1. 0 PURPOSE
The purpose of the multi-media, multi-concentration organic analytical
service is to provide analytical data for use by the U.S. Environmental
Protection Agency (EPA) in support of its investigation and clean-up
activities under the Comprehensive Environmental Response, Compensation,
and Liability Act of 1980 (CERCLA) and the Superfund Amendments and
Reauthorization Act of 1986 (SARA). Other EPA Program Offices who have
similar analytical data needs also use this service.
2.0 DESCRIPTION OF SERVICE
The organic analytical service provides a contractual framework for
laboratories to apply EPA Contract Laboratory Program (CLP) analytical
methods for the isolation, detection and quantitative measurement of 33
volatile, 64 semivolatile, and 28 pesticide/Aroclor target compounds in
water and soil/sediment environmental samples. The analytical service
provides the methods to be used, and the specific contractual
requirements by which EPA will evaluate the data. This service uses gas
chromatography/mass spectrometry (GC/MS) and gas chromatography/electron
capture (GC/EC) methods to analyze the target compounds.
3.0 DATA USES
This analytical service provides data which EPA uses for a variety of
purposes, such as determining the nature and extent of contamination at
a hazardous waste site, assessing priorities for response based on risks
to human health and the environment, determining appropriate cleanup
actions, and determining when remedial actions are complete. The data
may be used in all stages in the investigation of a hazardous waste site
including site inspections, Hazard Ranking System scoring, remedial
investigations/feasibility studies, remedial design, treatability
studies, and removal actions. In addition, this service provides data
that are available for use in Superfund enforcement/litigation
activities.
4.0 SUMMARY OF REQUIREMENTS
4.1 Introduction to the SOW. This statement of work (SOW) is designed as
part of the documentation for a contract between EPA and a commercial
laboratory performing analyses in support of EPA Superfund programs.
The SOW comprises eight exhibits. Exhibit A provides an overview of the
SOW and its general requirements. Exhibit B contains a description of
the reporting and deliverables requirements, in addition to the data
reporting forms and the forms instructions. Exhibit C specifies the
target compound list for this SOW with the contract-required
quantitation limits for sample matrices. Exhibit D details the specific
analytical procedures to be used with this SOW and resulting contracts.
Exhibit E provides descriptions of required quality assurance/quality
control (QA/QC), standard operating procedures, and procedures used for
evaluating analytical methodologies, QA/QC performance, and the
reporting of data. Exhibit "F contains chain-of-custody and sample
documentation requirements which the Contractor shall follow. To ensure
A-3 OLM03.0
-------
proper understanding of the terms utilized in this SOW, a glossary can
be found in Exhibit G. (When a term is used in the text without
explanation, the glossary meaning shall be applicable.) Specifications
for reporting data in computer-readable form appear in Exhibit H.
4.2 Overview of Major Task Areas. For each sample, the Contractor shall
perform the tasks described in this section. Specific requirements for
each task are detailed in the exhibits as referenced.
4.2.1 Task I: Chain-of-Custody
4.2.1.1 Chain-of-Custody. The Contractor shall receive and maintain
samples under proper chain-of-custody procedures. All associated
document control and inventory procedures shall be developed and
followed. Documentation, as described therein, shall be required
to show that all procedures are being strictly followed. This
documentation shall be reported as the Complete Sample Delivery
Group File (CSF) (see Exhibit B). The Contractor shall establish
and use appropriate procedures to handle confidential information
received from the Agency. See Exhibit F for specific
requirements.
4.2.1.2 Sample Scheduling/Shipments. Sample shipments to the Contractor's
facility will be scheduled and coordinated by the CLP Sample
Management Office (SMO). The Contractor shall communicate with
SMO personnel by telephone, as necessary throughout the process of
sample scheduling, shipment, analysis and data reporting, to
ensure that samples are properly processed.
4.2.1.2.1 Samples will be shipped routinely to the Contractor through an
overnight delivery service. However, as necessary, the
Contractor shall be responsible for any handling or processing
required for the receipt of sample shipments, including pick-up
of samples at the nearest servicing airport, bus station or
other carrier service within the Contractor's geographical
area. The Contractor shall be available to receive sample
shipments at any time the delivery service is operating,
including Saturdays.
4.2.1.2.2 If there are problems with the samples (e.g., mixed media,
containers broken or leaking) or sample documentation/paperwork
(e.g., Traffic Reports not with shipment, sample and Traffic
Report numbers do not correspond), the Contractor shall
immediately contact SMO for resolution. The Contractor shall
immediately notify SMO regarding any problems and laboratory
conditions that affect the timeliness of analyses and data
reporting. In particular, the Contractor shall notify SMO
personnel in advance regarding sample data that will be
delivered late and shall specify the estimated delivery date.
4.2.1.2.3 To more effectively monitor the temperature of the sample
shipping cooler, each USEPA Regional office may include a
sample shipping cooler temperature blank with each cooler
shipped. The temperature blank will be clearly labeled: USEPA
COOLER TEMPERATURE INDICATOR.
A-4 OLM03.0
-------
4.2.1.2.3.1 When the USEPA Regional office supplies a cooler temperature
indicator bottle in the sample shipping cooler, the Contractor
shall use the USEPA supplied cooler temperature indicator
bottle to determine the cooler temperature. The temperature of
the cooler shall be measured at the time of sample receipt by
the Contractor.
4.2.1.2.3.2 The temperature of the sample shipping cooler shall be measured
and recorded immediately upon opening the cooler, and prior to
unpacking the samples or removing the packing material.
4.2.1.2.3.3 To determine the temperature of the cooler, the contractor
shall locate the cooler temperature indicator bottle in the
sample shipping cooler, remove the cap and insert a calibrated
thermometer into the cooler temperature indicator bottle.
Prior to recording the temperature, the Contractor shall allow
a minimum of 3 minutes, but not greater than 5 minutes for the
thermometer to equilibrate with the liquid in the bottle. At a
minimum, the calibrated thermometer (±.1^_C) shall have a
measurable range of 0 to 50 degrees Celsius. Other devices
which can measure temperature may be used if they can be
calibrated to ±_1^_C and have a range of 0 to 20^_C.
4.2.1.2.3.4 If the temperature of the sample shipping cooler's temperature
indicator exceeds 10 degrees Celsius, the contractor shall
contact the Sample Management Office (SMO) and inform them of
the temperature deviation. The SMO will contact the Region
from which the samples were shipped for instructions on how to
proceed. The Region will either require that no sample
analysis(es) be performed or that the Contractor proceed with
the analysis(es). The SMO will in turn notify the Contractor
of the Region's decision. The Contractor shall document the
Region's decision in the SDG narrative. Also in the SDG
narrative, the Contractor shall list by fraction, the USEPA
sample number, all samples which were shipped in a cooler which
exceeded 10 degrees Celsius.
4.2.1.2.3.5 The Contractor shall record the temperature of the cooler on
the DC-1 Form, under Remark #8 - Sample Conditions, and in the
SDG narrative.
4.2.1.2.4 The Contractor shall accept all samples scheduled by SMO,
provided that the total number of samples received in any
calendar month does not exceed the monthly limitation expressed
in the contract. Should the Contractor elect to accept
additional samples, the Contractor shall remain bound by all
contract requirements for analysis of those samples accepted.
4.2.1.2.4 The Contractor shall be required to routinely return sample
shipping containers (e.g., coolers) to the appropriate sampling
office within 14 calendar days following shipment receipt (see
Clause entitled Government Furnished Supplies and Materials).
4.2.2 Task II: Analysis of Samples
4.2.2.1 Overview. Sample analyses will be scheduled by groups of samples,
each defined as a Case and identified by a unique EPA Case number
A-5 OLM03.1
-------
assigned by SMO. A Case signifies a group of samples collected at
one site or geographical area over a finite time period, and will
include one or more field samples with associated blanks. Samples
may be shipped to the Contractor in a single shipment or multiple
shipments over a period of time, depending on the size of the
Case.
4.2.2.1.1 A Case consists of one or more Sample Delivery Group(s). A
Sample Delivery Group (SDG) is defined by the following,
whichever is most frequent:
• Each Case of field samples received, OR
• Each 20 field samples within a Case, OR
• Each 14 calendar day period (7 calendar day period for 14-
day data turnaround contracts) during which field samples
in a Case are received (said period beginning with the
receipt of the first sample in the SDG).
4.2.2.1.2 Samples may be assigned to SDGs by matrix (i.e., all soils in
one SDG, all waters in another), at the discretion of the
laboratory. Such assignment shall be made at the time the
samples are received, and shall not be made retroactively.
4.2.2.2 Preparation Techniques. Prepare samples as described in Exhibit
D. For semivolatile and pesticide/Aroclor samples, an aliquot is
ext. .cted with a solvent and concent ated. The concentrated
extract is subjected to fraction-specific cleanup procedures and
then analyzed by GC/MS for semivolatile or GC/EC for the
pesticide/Aroclor target compounds listed in Exhibit C. For
volatile samples, an aliquot is purged with an inert gas, trapped
on a solid sorbent, and then desorbed onto the GC/MS for analysis
of the target compounds listed in Exhibit C.
4.2.2.3 Analytical Techniques. The target compounds listed in Exhibit C
shall be identified as described in the methodologies given in
Exhibit D. Automated computer programs may be used to facilitate
the identification of compounds.
4.2.2.4 Qualitative Verification of Compounds. The volatile and
semivolatile compounds identified by GC/MS techniques shall be
verified by an analyst competent in the interpretation of mass
spectra by comparison of the suspect mass spectrum to the mass
spectrum of a standard of the suspected compound. This procedure
requires the use of multiple internal standards.
4.2.2.4.1 If a compound initially identified by GC/MS techniques cannot
be verified, but in the technical judgment of the mass spectral
interpretation specialist the identification is correct, then
the Contractor shall report that identification and proceed
with quantitation.
4.2.2.4.2 The pesticide/Aroclor compounds identified by GC/EC techniques
shall be verified by an analyst competent in the interpretation
A-6 OLM03.0
-------
of gas chromatograms and by comparison of the retention times
of the suspected unknowns with the retention times of
respective standards of the suspected compounds. Compounds
shall also be confirmed by GC/MS techniques if the compounds
are of sufficient concentration to be detected by the GC/MS.
4.2.2.5 Quantitation of Verified Compounds. The Contractor shall
quantitate components identified by GC/MS techniques by the
internal standard method stipulated in Exhibit D. Where multiple
internal standards are required by EPA, the Contractor shall
perform quantitation utilizing the internal standards specified in
Exhibit D. The Contractor shall quantitate components analyzed by
GC/EC techniques by the external standard method stipulated in
Exhibit D. The Contractor shall also perform an initial three-
point calibration, verify its linearity, determine the breakdown
of labile components, and determine calibration factors for all
standards analyzed by GC/EC techniques as described in Exhibit D.
4.2.2.6 Tentative Identification of Non-Target Sample Components. For
each analysis of a sample, the Contractor shall conduct mass
spectral library searches to determine tentative compound
identifications as follows. For each volatile sample, the
Contractor shall conduct a search to determine the possible
identity of up to 30 organic compounds of greatest concentration
which are not system monitoring compounds or internal standards
and are not listed in Exhibit C under volatiles or semivolatiles.
For each semivolatile sample, the Contractor shall conduct a
search to determine the possible identification of up to 30
organic compounds of greatest concentration which are not
surrogates or internal standards and are not listed in Exhibit C
under volatiles or semivolatiles. In performing searches, the
NIST/EPA/NIH (May 1992 release or later) and/or Wiley (1991
release or later), or equivalent, mass spectral library shall be
used.
NOTE: Substances with responses less than 10% of the nearest
internal standard are not required to be searched in this fashion.
4.2.2.7 Quality Assurance/Quality Control Procedures. The Contractor
shall strictly adhere to all specific QA/QC procedures prescribed
in Exhibits D and E. Records documenting the use of the protocol
shall be maintained in accordance with the document control
procedures prescribed in Exhibit F, and shall be reported in
accordance with Exhibit B and Exhibit H.
4.2.2.7.1 The Contractor shall maintain a Quality Assurance Plan (QAP)
with the objective of providing sound analytical chemical
measurements. This program shall incorporate the quality
control procedures, any necessary corrective action, and all
documentation required during data collection as well as the
quality assessment measures performed by management to ensure
acceptable data production.
4.2.2.7.2 Additional quality control shall be conducted in the form of
the analysis of laboratory evaluation samples submitted to the
A-7 OLM03.0
-------
laboratory by the Agency. The results of all such quality
control or laboratory evaluation samples may be used as the
basis for an equitable adjustment to reflect the reduced value
of the data to the Agency or rejection of data for: sample(s),
a fraction within an SDG, or the entire SDG, and/or may be used
as the basis for contract action. "Compliant performance" is
defined as that which yields correct compound identification
and concentration values as determined by the Agency, as well
as meeting the contract requirements for analysis (Exhibit D),
quality assurance/quality control (Exhibit E), data reporting
and other deliverables (Exhibits B and H), and sample custody,
sample documentation and standard operating procedure
documentation (Exhibit F).
4.2.3 Task III: Reporting Requirements
4.2.3.1 EPA has provided to the Contractor formats for the reporting of
data (Exhibits B and H). The Contractor shall be responsible for
completing and returning analysis data sheets and submitting
computer-readable data on diskette in the format specified in this
SOW and within the time specified in the Contract Performance/
Delivery Schedule in Exhibit B.
4.2.3.2 Use of formats other than those designated by EPA will be deemed
as noncompliant. Such data are unacceptable. Resubmission in the
specified format at no additional cost to the Agency shall be
required.
4.2.3.3 Computer-generated forms may be submitted in the hardcopy data
package(s) provided that the forms are in exact EPA format. This
means that the order of data elements is the same as on each EPA-
required form, including form numbers and titles, page numbers and
header information.
4.2.3.4 The data reported by the Contractor on the hardcopy data forms and
the associated computer-readable data submitted by the Contractor
shall contain identical information. If discrepancies are found
during government inspection, the Contractor shall be required to
resubmit either the hardcopy forms or the computer-readable data,
or both sets of data, at no additional cost to the Agency.
A-8 OLM03.0
-------
4.3 Technical and Management Capability
4.3.1 Personnel. The Contractor shall have adequate personnel at all times
during the performance of the contract to ensure that EPA receives
data that meet the terms and conditions of the contract.
4.3.2 Instrumentation. The Contractor shall have sufficient gas
chromatograph/electron capture/data system (GC/EC/DS), gas
chromatograph/mass spectrometer/data system (GC/MS/DS), including
magnetic tape storage devices, and gel permeation chromatography
system (GPC) capability to meet all the terms and conditions of the
contract.
4.3.3 Facilities. The Contractor shall maintain a facility suitable for
the receipt, storage, analysis, and delivery of the product meeting
the terms and conditions of the contract.

major units described in this section. The last three units are each
specific to an analytical fraction (yolatiles, semivolatiles, and
pesticides/Aroclors). If the analysis of a fraction is not required,
then that fraction-specific unit is not required as a deliverable. The
sample data package shall include data for the analyses of all samples in
one SDG, including field samples, dilutions, reanalyses, blanks, matrix
spikes, and matrix spike duplicates. The Contractor shall retain a copy
of the sample data package for 365 days after final acceptance of data.

Exhibit B—Section 3
Forms Instructions
General Information
3.0 FORMS INSTRUCTIONS
3.1 Introduction. This section includes specific instructions for
completing the data reporting forms required under this contract. Each
of the forms is specific to a given fraction (volatile, semivolatile, or
pesticide/Aroclor) and, in some instances, specific to a given matrix
(water or soil) within each fraction. The Contractor shall submit only
those forms pertaining to the fractions analyzed for a given sample(s).
For instance, if a sample is scheduled for volatiles analysis only, the
Contractor shall provide only forms for the volatile fraction. NOTE:
There are two pages relating to the semivolatile fraction for Forms I,
VI, VII, and VIII. Whenever semivolatiles are analyzed and one of these
forms is required, both pages (SV-1 and SV-2) shall be submitted.
3.2 General Information. The Contractor shall report values on the hardcopy
forms according to the individual form instructions in this section.
For example, results for concentrations of volatile target compounds
shall be reported to two significant figures if the value is greater
than or equal to 10. Values that exceed the maximum length allowed
shall be reported to the maximum possible, maintaining the specified
decimal place.
3.2.1 The data reporting forms presented in Section 4 have been designed in
conjunction with the computer-readable data format specified in
Exhibit H. The specific length of each variable for
computer-readable data transmission purposes is also given in Exhibit
H. Information entered on these forms shall not exceed the size of
the field given on the form, including such laboratory-generated
items as lab name and lab sample identifier.
NOTE: The space provided for entries on the hardcopy forms (Section
4) is greater in some instances than the length prescribed for the
variable as written to diskette (see Exhibit H). Greater space is
provided on the hardcopy forms for visual clarity.
3.2.2 When submitting data, the Contractor shall reproduce all characters
that appear on the data reporting forms in Section 4. The format of
the forms submitted shall be identical to that shown in the contract.
No information may be added, deleted, or moved from its specified
position without prior written approval of the Administrative Project
Officer. The names of the various fields and compounds (e.g., "Lab
Code," "Chloromethane") shall appear as they do on the forms in the
contract, including the options specified in the form (e.g., "Matrix:
(soil/water)" shall appear, not just "Matrix"). For items appearing
on the uncompleted forms (Section 4), the use of uppercase and
lowercase letters is optional.
3.2.3 Alphabetical entries made on the forms by the Contractor shall be in
ALL UPPERCASE letters (e.g., "LOW", not "Low" or "low"). If an entry
does not fill the entire blank space provided on the form, null
characters shall be used to remove the remaining underscores that
comprise the blank line. See Exhibit H for more detailed
B-31 OLM03.0
-------
Exhibit B—Section 3
Forms Instructions
General Information
instructions. However, the Contractor shall not remove the
underscores or vertical bars that delineate "boxes" on the forms.
The only exception would be those underscores at the bottom of a
"box" that are intended as a data entry line. (For instance, on Form
2A, line 30, if data is entered on line 30, it will replace the
underscores.)
3.3 Header Information. Six pieces of information are common to the header
section of each data reporting form: lab name, contract, lab code, Case
number, SAS number and SDG number. Except as noted for SAS number, this
information shall be entered on every form and shall match on every
form.
3.3.1 Lab Name. The lab name shall be the name chosen by the Contractor to
identify the laboratory. It shall not exceed 25 characters.
3.3.2 Contract. Contract refers to the number of the EPA contract under
which the analyses were performed.
3.3.3 Lab Code. The lab code is an alphabetical abbreviation of up to six
letters, as assigned by EPA, to identify the laboratory and aid in
data processing. This lab code will be assigned by EPA at the time a
contract is awarded, and shall not be modified by the Contractor,
except at the direction of EPA. If a change of name or ownership
occurs at the laboratory, the lab code will remain the same until the
Contractor is directed by EPA to use another lab code.
3.3.4 Case Number. The Case number is the EPA-assigned Case number
associated with the sample. This number is reported on the Traffic
Report.
3.3.5 SAS Number. The SAS number is the EPA-assigned number for analyses
performed under Special Analytical Services. If samples are to be
analyzed under SAS only and reported on these forms, then enter the
SAS number and leave the case number blank. If samples are analyzed
according to the Routine Analytical Services (RAS) protocols and have
additional SAS requirements, list both the Case number and the SAS
number on all forms. If there are no SAS requirements, leave the
"SAS No." field blank.
NOTE: Some samples in an SDG may have a SAS number while others may
not.
3.3.6 SDG Number. The "SDG No." field is for the sample delivery group
number. It is the EPA sample number of the first sample received in
the SDG. When several samples are received together in the first SDG
shipment, the SDG number shall be the lowest sample number
(considering both alpha and numeric designations) in the first group
of samples received under the SDG.
3.3.7 Sample Number. This number appears either in the upper righthand
corner of the form, or as the left column of a table summarizing data
B-32 OLM03.0
-------
Exhibit B—Section 3
Forms Instructions
General Information
from a number of samples. When the EPA sample number is entered in
the triple-spaced box in the upper righthand corner of Form I, Form
IV, or Form X, it should be entered on the middle line of the three
lines that comprise the box.
3.3.7.1 The Contractor shall identify all samples, including dilutions and
reanalyses, matrix spikes, matrix spike duplicates, blanks, and
standards with an EPA sample number. For field samples, matrix
spikes and matrix spike duplicates, the EPA sample number is the
unique identifying number given in the Traffic Report that
accompanied that sample. In order to facilitate data assessment,
the Contractor shall use the following sample suffixes:
XXXXX = EPA sample number
XXXXXMS = Matrix spike sample
XXXXXMSD = Matrix spike duplicate sample
XXXXXRE = Re-extracted and reanalyzed sample
XXXXXDL = The suffix DL is appended to the EPA
sample number to indicate that the
analytical results are a result of a
dilution of the original analysis
(reported as EPA sample XXXXX). See
Exhibit D for requirements for
dilutions.
3.3.7.2 There may be instances when all samples analyzed must be listed on
the form, regardless of whether or not they are part of the SDG
being reported (e.g., Form VIII PEST). In these instances, use
ZZZZZ as the EPA sample number for any sample analysis not
associated with the SDG being reported.
3.3.7.3 For blanks, the Contractor shall use the following identification
scheme for the EPA sample number:
• Volatile method blanks shall be identified as VBLK##.
• Volatile instrument blanks shall be identified as VIBLK##.
• Volatile storage blanks shall be identified as VHBLK##.
• Semivolatile method blanks shall be identified as SBLK##.
• Pesticide/Aroclor method blanks and/or sulfur cleanup blanks
shall be identified as PBLK##.
• Pesticide/Aroclor instrument blanks shall be identified as
PIBLK##.
3.3.7.4 The EPA sample number shall be unique for each blank within an
SDG. Within a fraction, the Contractor shall achieve this by
replacing the two-character terminator (##) of the identifier with
B-33 OLM03.0
-------
Exhibit B—Section 3
Forms Instructions
General Information
3.3.7.5
3.3.7.6
one or two characters or numbers, or a combination of both. For
example, possible identifiers for volatile blanks would be VBLK1,
VBLK2, VBLKA1, VBLKB2, VBLK10, VBLKAB, etc. If the method blank
is analyzed on multiple instruments, then an additional two-
character suffix shall be added to make the blank EPA sample
number unique.
Volatile and semivolatile standards shall be identified as
FSTD***##, where
F = Fraction code (V for volatiles; S for semivolatiles).
STD = Standard.
* * * =
##
Concentration of volatile standards in ug/L (e.g.,
010, 020, 050, 100, and 200) or the amount injected in
ng for semivolatile standards (e.g., 020, 050, 080,
120, and 160).
One or two characters, numbers, or combinations of
both to create a unique EPA sample number within an
SDG.
The Contractor shall use the following scheme to identify
pesticide/Aroclor standards:
Name

General Information
The Contractor shall replace the two-character terminator (##) of
the identifier with one or two characters or numbers, or a
combination of both, to create a unique EPA sample number within
an SDG.
3.3.7.7 If the standards are injected onto both GC columns on the same
instrument simultaneously, the same EPA sample number may be used
for reporting data for the standards for both columns. If
simultaneous injections are not made, then the same number shall
not be used.
3.3.7.8 The EPA sample number for GPC shall be GPC#########, where
######### is the GPC column ID. If the GPC column ID is more than
nine characters, truncate at the ninth character.
3.3.7.9 The EPA sample number for florisil shall be FLO#########, where
######### is the florisil cartridge lot number. If the florisil
cartridge lot number is more than nine characters, truncate at the
ninth character.
3.3.8 Other Common Fields. Several other pieces of information are common
to many of the data reporting forms. These include matrix, sample
weight/volume, level, lab sample identifier, and lab file identifier.
• In the "Matrix" field, enter SOIL for soil/sediment samples and
WATER for water samples.
NOTE: The matrix shall be spelled out. Abbreviations such as S
or W shall not be used.
• In the "Sample wt/vol" field, enter the number of grams (for
soil) or milliliters (for water) of sample used in the first
blank. Enter the units, either G or ML, in the second blank.
• The "Level" field is used for the volatile and semivolatile
fractions. Enter the determination of concentration level made
from the screening of soils. Enter as LOW or MED, not L or M.
All water samples shall be entered as LOW.
NOTE: There is no differentiation between low and medium soil
samples for the pesticide/Aroclor fraction, and no level is
entered on any of these forms.
• The lab sample identifier is a unique laboratory-generated
internal identifier pertaining to a particular analysis. The
Contractor can enter up to 12 alpha-numeric characters in the
"Lab Sample ID" field. The Contractor may use the EPA sample
number ?.s the lab sample identifier.
• The lab file identifier is the unique laboratory-generated name
of the GC/MS data system file containing information pertaining
B-35 OLM03.0
-------
Exhibit B — Section 3
Forms Instructions
Form I
to a particular analysis. The Contractor can enter up to 14
alpha-numeric characters in the "Lab File ID" field.
3.3.8.1 The "Instrument ID" field is common to the forms containing
calibration data. The identifier used by the Contractor shall
include some indication of the manufacturer and/or model of the
instrument, and shall contain additional characters that
differentiate between all instruments of the same type in the
laboratory.
3.3.8.2 Forms II, IV, V, VIII, IX, and X contain a field labeled "page _
of _" in the bottom lefthand corner. If the number of entries
reg_uired on any of these forms exceeds the available space,
continue entries on another copy of the same fraction-specific
form, duplicating all header information. If a second page is
required, number the pages consecutively (i.e., "page I of 2" and
"page 2 of 2"). If a second page is not required, number the page
"page 1 of 1."
NOTE: These forms are fraction-specific, and often matrix-
specific within a fraction. For example, Form II VOA-1 and Form
II VOA-2 are for different data. Therefore, do not number the
pages of all six versions of Form II as "1 of 6," "2 of 6," etc.
Number only pages corresponding to the fraction-specific and
matrix-specific form.
3.3.9 Rounding Rule. For rounding off numbers to the appropriate level of
precision, the Contractor shall follow these rules. If the figure
following those to be retained is less than 5, drop it (round down).
If the figure is greater than 5, drop it and increase the last digit
to be retained by 1 (round up). If the figure following the last
digit to be retained equals 5, round up if the digit to be retained
is odd, and round down if that digit is even.
3.4 Organic Analysis Data Sheet (Form I, All Fractions)
3.4.1 Purpose. This form is used for tabulating and reporting sample
analysis, including blank, matrix spike, and matrix spike duplicate
results for target compounds. If all fractions are not requested for
analysis, only the pages for the fractions required shall be
submitted. For example, if only volatiles analysis is requested,
Form I VOA and Form I VOA-TIC shall be submitted. If only the
pesticide/Aroclor fraction is requested for analysis, Form I PEST
shall be submitted. Furthermore, pesticide instrument blanks
(PIBLKs) shall be reported on a per column/per analysis basis on Form
I PEST. Each PIBLK shall be named with a unique EPA sample number.
3.4.2 Instructions. Complete the header information according to the
instructions in Section 3.3. Complete the remainder of the form
using the following instructions.
B-36 OLM03.0

Exhibit B — Section 3
Forms Instructions
Form I
3.4.2.1 For soil samples analyzed for volatiles, enter the non-decanted
percent moisture in the "% Moisture: not dec." field on Form I
VOA. This is the only percent moisture determination made for
volatiles since the entire contents of the VOA vial are considered
as the sample. For water samples, leave this field blank.
3.4.2.2 For soil samples analyzed for semivolatiles and
pesticides/Aroclors, enter the values for the percent moisture
determined during the analysis in the "% Moisture" field on Form I
SV-1, SV-2 or PEST. In the "decanted (Y/N)" field, enter Y if the
sample had standing water above the soil/sediment that was
decanted, or N if no water was decanted off the surface of the
sample. Report percent moisture (decanted or not decanted) to the
nearest whole percentage point (e.g., 5%, not 5.3%). For water
samples, method blanks, sulfur cleanup blanks and instrument
blanks, leave these fields on Form I blank.
3.4.2.3 For volatiles, enter the GC column identifier in the "GC Column"
field on Form I VOA, and the internal diameter in millimeters

holding times were not exceeded.
3.4.2.9 If a medium soil sample is analyzed for volatiles, enter total
volume of the methanol extract in microliters (uL) in the "Soil
Extract Volume" field on Form I VOA. This volume includes any
methanol not collected from the filtration of the extract through
glass wool; the volume is typically 10,000 uL (i.e., the 10 mL of
methanol used for the extraction). If a medium soil sample is
analyzed, enter the volume of the methanol extract added to the
reagent water in the purge tube and analyzed in the "Soil Aliquot
Volume" field. Enter this volume in microliters (uL).
3.4.2.10 For semivolatiles and pesticides/Aroclors, enter the actual volume
of the most concentrated sample extract, in microliters (uL), in
the "Concentrated Extract Volume" field on Form I SV-1, SV-2 or
PEST. For semivolatiles, this volume will typically be 1,000 uL
(for water) or 500 uL (for water and soil) when GPC is performed.
For pesticides/Aroclors, the volume of the most concentrated
extract will typically be 10,000 uL (for water) or 5,000 uL (for
water and soil) when GPC is performed. For pesticides/Aroclors,
the volume of the most concentrated extract is not the volume
taken through the Florisil and sulfur cleanup steps. If a
dilution of the sample extract is made in a subsequent analysis,
this volume will remain the same, but the dilution factor will
change.
3.4.2.11 For semivolatiles and pesticides/Aroclors, enter the volume of the
sample extract injected into the GC in the "Injection Volume"
field on Form I SV-1, SV-2 or PEST. Report this volume in
microliters (uL) to one decimal place (e.g., 1.0 uL) .
NOTE: A 2.0 microliter injection is required for semivolatile
analyses.
3.4.2.12 If pesticides/Aroclors are analyzed using two GC columns connected
to a single injection port, enter the amount of half the volume in
the syringe in the "Injection Volume" field (i.e., assume that the
extract injected is evenly divided between the two columns).
3.4.2.13 If a sample or sample extract has been diluted for analysis, enter
the dilution factor as a single number (e.g., enter 100.0 for a 1
to 100 dilution of the sample) in the "Dilution Factor" field.
The dilution factor shall not be entered as a fraction. If a
sample was not diluted, enter 1.0. Report dilution factors to one

3.4.2.15 For positively identified target compounds, the Contractor shall
report the concentrations as uncorrected for blank contaminants.
3.4.2.16 For volatile and semivolatile results, report analytical results
to one significant figure if the value is less than 10, and two
significant figures if the value is 10 or above. Report all
pesticide/Aroclor results to two significant figures.
3.4.2.17 Enter the appropriate concentration units, ug/L or ug/Kg.
3.4.2.18 Under the column labeled "Q" for qualifier, flag each result with
the specific data reporting qualifiers listed below. When
reporting results to EPA, the Contractor shall use these contract-
specific qualifiers. The Contractor shall not modify the
qualifiers. Up to five qualifiers may be reported on Form I for
each compound. The Contractor is encouraged to use additional
flags or footnotes (see the X qualifier).
The EPA-defined qualifiers to be used are:
U: This flag indicates the compound was analyzed for but not
detected. The CRQL shall be adjusted according to the
equation listed in Exhibit D. CRQLs are listed in Exhibit C.
J: This flag indicates an estimated value This flag is used
(1) when estimating a concentration for tentatively
identified compounds where a 1:1 response is assumed, (2)
when the mass spectral and retention time data indicate the
presence of a compound that meets the volatile and
semivolatile GC/MS identification criteria, and the result is
less than the CRQL but greater than zero, and (3) when the
retention time data indicate the presence of a compound that
meets the pesticide/Aroclor identification criteria, and the
result is less than the CRQL but greater than zero. For
example, if the sample quantitation limit is 10 ug/L, but a
concentration of 3 ug/L is calculated, report it as 3J.
NOTE: The J flag is not used and the compound is not
reported as being identified for pesticide/Aroclor results
less than the CRQL if the pesticide residue analysis expert
determines that the peaks used for compound identification
resulted from instrument noise or other interferences (column
bleed, solvent contamination, etc.).
N: This flag indicates presumptive evidence of a compound. This
flag is only used for tentatively identified compounds
(TICs), where the identification is based on a mass spectral
library search. It is applied to all TIC results. For
generic characterization of a TIC, such as chlorinated
hydrocarbon, the N flag is not used.

P: This flag is used for a pesticide/Aroclor target analyte when
there is greater than 25% difference for detected
concentrations between the two GC columns (see Form X). The
lower of the two values is reported on Form I and flagged
with a P.
C: This flag applies to pesticide results where the
identification has been confirmed by GC/MS. If GC/MS
confirmation was attempted but was unsuccessful, do not apply
this flag; use a laboratory-defined flag instead (see the X
qualifier).
B: This flag is used when the analyte is found in the associated
method blank as well as in the sample. It indicates probable
blank contamination and warns the data user to take
appropriate action. This flag shall be used for a
tentatively identified compound as well as for a positively
identified target compound.
The combination of flags BU or UB is expressly prohibited.
Blank contaminants are flagged B only when they are detected
in the sample.
E: This flag identifies compounds whose concentrations exceed
the upper level of the calibration range of the instrument
for that specific analysis. If one or more compounds have a
response greater than the upper level of the calibration
range, the sample or extract shall be diluted and reanalyzed
according to the specifications in Exhibit D; exceptions are
also noted in Exhibit D. All such compounds with a response
greater than the upper level of the calibration range shall
have the concentration flagged with an E on Form I for the
original analysis.
NOTE: For total xylenes, where three isomers are quantified
as two peaks, the calibration range of each peak shall be
considered separately. For example, a diluted analysis is
not required for total xylenes unless the concentration of
the peak representing the single isomer exceeds 200 ug/L or
the peak representing the two co-eluting isomers on that GC
column exceeds 400 ug/L. Similarly, if the two 1,2-
Dichloroethene isomers coelute, a diluted analysis is not
required unless the concentration exceeds 400 ug/L.
D: If a sample or extract is reanalyzed at a higher dilution
factor, for example when the concentration of an analyte
exceeds the upper calibration range, the DL suffix is
appended to the sample number on Form I for the more diluted
sample, and all reported concentrations on that Form I are
flagged with the D flag. This flag alerts data users that
any discrepancies between the reported concentrations may be
due to dilution of the sample or extract. NOTE 1: The D

reporting the original analysis (EPA Sample No. XXXXX) and
the more diluted sample analysis (EPA Sample No. XXXXXDL)
i.e. the results from both analyses cannot be combined on a
single Form I.
A: This flag indicates that a tentatively identified compound is
a suspected aldol-condensation product.
X: Other specific flags may be required to properly define the
results. If used, the flags shall be fully described, with
the description attached to the sample data summary package
and the SDG Narrative. Begin by using X. If more than one
flag is required, use Y and Z as needed. If more than five
qualifiers are required for a sample result, use the X flag
to represent a combination of several flags. For instance,
the X flag might combine the A, B, and D flags for some
samples. The laboratory-defined flags are limited to X, Y,
and Z.

flagged A, and included in the "Number TICs found" field. The
peaks shall be counted as part of the 30 most intense non-target
semivolatile compounds to be searched.
3.6 System Monitoring Compound Recovery (Form II VOA)
3.6.1 Purpose. For volatiles, Form II VOA is used to report the recoveries
of the system monitoring compounds added to each volatile sample,
including dilutions and reanalyses, blank, matrix spike, and matrix
spike duplicate. The system monitoring compounds are used to monitor
the performance of the purge and trap-gas chromatograph-mass
spectrometer system as a whole. Form II VOA is matrix-specific, so
that system monitoring compound recoveries for \ fater samples are
reported on a different version of Form .1 than the recoveries for
soil samples. Soil sample recoveries are further differentiated by
concentration level.
3.6.2 Instructions. Complete the header information according to the

3.7 Surrogate Recovery (Form II SV and Form II PEST)
3.7.1 Purpose. Form II SV and Form II PEST are used to report the
recoveries of the surrogate compounds added to each semivolatile and
pesticide/Aroclor sample, blank, matrix spike, and matrix spike
duplicate. Form II SV and Form II PEST are matrix-specific as well
as fraction-specific, so surrogate recoveries for semivolatile and
pesticide water samples are reported on a different version of Form
II than surrogate recoveries for semivolatile and pesticide soil
samples.
3.7.2 Instructions. Complete the header information according to the
instructions in Section 3.3. NOTE: For semivolatile soil samples
only, specify the level as LOW or MED. Complete one form for each

shall be consistent across all the reporting forms. If the
analysis is not performed by simultaneous injection, then the
assignment of GC column number shall be based on the
chronological order of the two analyses.
3.7.2.7 Although the pesticide surrogate recovery limits for samples,
matrix spike and matrix spike duplicates are only advisory, the
Contractor shall flag those recoveries that are outside the
advisory QC limits or are diluted out. The total number of
recoveries that are outside the QC limits shall include all

3.12 GC/EC Initial Calibration Data (Form VI PEST)
3.12.1 Purpose. The initial calibration of pesticides/Aroclors involves the
determination of retention times, retention time windows, and
calibration factors. For single component pesticide target
compounds, these data are calculated from the analyses of the
Individual Standard Mixtures A and B at three different concentration
levels. For the multicomponent target compounds, these data are
calculated from a single point calibration.
3.12.2 Instructions. Complete one Form VI for each GC column used for the
three analyses of Individual Standard Mixture A (low point, mid-
point, and high point) and the three analyses of Individual Standard
Mixture B during an initial calibration. Complete the header
information according to the instructions in Section 3.3. Complete
the remainder of the form using the following instructions.
3.12.2.1 In the "Level (x low)" field, enter the concentration of the low
point, mid-point, and high point calibration standards as a
multiplier of the low point. Therefore, for the low point, enter
"1.0." The concentration of the mid-point standard is specified
in Exhibit D as four times the low point; therefore, enter "4.0."
The high point standard shall be at least 16 times the low point,
but may be higher, if that value lies within the linear range of
the instrument, as specified in Exhibit D. Therefore, enter the
appropriate multiplier to the high point standard concentration to
one decimal place.
3.12.2.2 Identify the GC column and internal diameter (in millimeters, mm)
in the appropriate fields.
3.12.2.3 Enter the dates of analysis of the first and last of the six
standards on each form in the "Date(s) Analyzed" field. Dates
shall be entered as MM/DD/YY.
3.12.2.4 For each standard analyzed, enter the retention time of each
applicable analyte in minutes and decimal minutes, under the
appropriate concentration level in the "RT OF STANDARDS" column on

3.20.1 Purpose. The Document Inventory Sheet (Form DC-2) is used to record
both the inventory of Complete SDG File (CSF) documents and the
number of documents in the original sample data package which is sent
to the EPA Region.
3.20.2 Instructions
3.20.2.1 Organize all EPA CSF documents as described in Exhibit B, Sections
II and III. Assemble the documents in the order specified on Form
DC-2 and Sections II and III, and stamp each page with a
consecutive number; however, do not number Form DC-2. Inventory
the JSF by reviewing the document numbers and recording page
number ranges in the columns provided on Form DC-2. The
Contractor shall verify and record in the "Comments" section on
Form DC-2 all intentional gaps in the page numbering sequence (for
example, "page numbers not used, XXXX - XXXX, XXXX - XXXX. If
there are no documents for a specific document type, enter a "NA"
in the empty space.
3.20.2.2 Certain laboratory-specific documents related to the CSF may not
fit into a clearly defined category. The Contractor shall review
Form DC-2 to determine if it is most appropriate to place them
under categories 7, 8, 9, or 10. Category 10 should be used if
there is no appropriate previous category. These types of
documents should be described or listed in the blanks under each
appropriate category on Form DC-2.
3.20.2.3 If it is necessary to insert new or inadvertently omitted
documents, the Contractor shall identify the documents with unique
accountable numbers and record the unique accountable numbers and
the locations of the documents in the CSF in the "Other Records"
section on Form DC-2.

Scope and Application
1.0 SCOPE AND APPLICATION
1.1 The analytical method that follows is designed to analyze water,
sediment and soil from hazardous waste sites for the organic compounds
on the Target Compounds List (TCL, see Exhibit C). The method is based
on EPA Method 624 (Purgeables).
1.2 The method includes sample preparation, a hexadecane screening procedure
on a GC/FID to determine the approximate concentration of organic
constituents in the sample (Appendix A), and the actual analysis which
is based on a purge and trap gas chromatograph/mass spectrometer (GC/MS)
method.
1.3 Problems have been associated with the following compounds analyzed by
this method:
• Chloromethane, vinyl chloride, bromomet.iane, and chloroethane can
display peak broadening if the compounds are not delivered to the GC
column in a tight band.
• Acetone, hexanone, 2-butanone, and 4-methyl-2-pentanone have poor
purge efficiencies.
• 1,1,1-trichloroethane and all the dichloroethanes can
dehydrohalogenate during storage or analysis.
• Chloromethane can be lost if the purge flow is too fast.
• Bromoform is one of the compounds most likely to be adversely
affected by cold spots and/or active sites in the transfer lines.
Response of its quantitation ion (m/z 173) is directly affected by
the tuning of the GC/MS to meet the instrument performance criteria
for 4-bromofluorobenzene (BFB) at ions m/z 174/176. Increasing the
m/z 174/176 ratio may improve bromoform response.

Summary of Method/Definitions
2.0 SUMMARY OF METHOD
2.1 Water
An inert gas is bubbled through a 5 mL sample contained in a
specifically designed purging chamber at ambient temperature. The
purgeable compounds are efficiently transferred from the aqueous phase
to the vapor phase. The vapor is swept through a sorbent column where
the purgeables are trapped. After purging is completed, the sorbent
column is heated and backflushed with the inert gas to desorb the
purgeable compounds onto a gas chromatographic column. The gas
chromatograph is temperature-programmed to separate the purgeable
compounds which are then detected with a mass spectrometer.
2.2 Low Soil
An inert gas is bubbled through a mixture of reagent water and 5 g of
sample contained in a specifically designed purging chamber that is held
at an elevated temperature. The purgeable compounds are efficiently
transferred from the aqueous phase to the vapor phase. The vapor is
swept through a sorbent column where the purgeables are trapped. After
purging is completed, the sorbent column is heated and backflushed with
the inert gas to desorb the purgeable compounds onto a gas
chromatographic column. The gas chromatograph is temperature-programmed
to separate the purgeable compounds which are then detected with a mass
spectrometer.

A measured amount of soil is extracted with methanol. A portion of the
methanol extract is diluted to 5 mL with reagent water. An inert gas is
bubbled through this solution in a specifically designed purging chamber
at ambient temperature. The purgeable compounds are effectively
transferred from the aqueous phase to the vapor phase. The vapor is
swept through a sorbent column where the purgeables are trapped. After
purging is completed, the sorbent column is heated and backflushed with
the inert gas to desorb the purgeable compounds onto a gas
chromatographic column. The gas chromatograph is temperature-programmed
to separate the purgeable compounds which are then detected with a mass
spectrometer.

Interferences/Safety
4.0 INTERFERENCES
4.1 Method interference may be caused by impurities in the purge gas,
organic compounds out-gassing from the plumbing ahead of the trap, and
solvent vapors in the laboratory. The analytical system must be
demonstrated to be free from contamination under the conditions of the
analysis by running laboratory method and instrument blanks- as described
in Section 12. The use of non-Polytetrafluoroethylene (PTFE) tubing,
non-PTFE thread sealants, or flow controllers with rubber components in
the purging device should be avoided.
4.2 Samples can be contaminated by diffusion of volatile organics
(particularly fluorocarbons and methylene chloride) through the septum
seal into the sample during storage and handling.
4.3 Contamination by carryover can occur whenever high level and low level
samples are sequentially analyzed. To reduce carryover, the purging
device and sampling syringe must be rinsed with reagent water between
sample analyses. For samples containing large amounts of water-soluble
materials, suspended solids, high-boiling compounds, or high purgeable
levels, it may be necessary to wash out the purging device with a
detergent solution between analyses, rinse it with distilled water, and
then dry it in an oven at 105 °C. The trap and other parts of the
system are also subjected to contamination; therefore, frequent bakeout
and purging of the entire system may be required.
4.4 The laboratory where volatile analysis is performed should be completely
free of solvents.
5.0 SAFETY
5.1 The toxicity or carcinogenicity of each reagent used in this method has
not been precisely defined; however, each chemical compound should be
treated as a potential health hazard. From this viewpoint, exposure to
these chemicals must be reduced to the lowest possible level by whatever
means available. The laboratory xs responsible for maintaining a
current awareness file of OSHA regulations regarding the safe handling
of the chemicals specified in this method. A reference file of material
data hand]ing sheets should also be made available to all personnel
involved in the chemical analysis.
5.2 The following analytes covered by this method have been tentatively
classified as known or suspected, human or mammalian carcinogens:
benzene, carbon tetrachloride, chloroform and vinyl chloride. Primary
standards of these toxic compounds should be prepared in a hood. A
NIOSH/MESA approved toxic gas respirator should be worn when the analyst
handles high concentrations of these toxic compounds.

observed at or above the CRQL of the analytes of interest. Reagent
water may be generated by passing tap water through a carbon filter
bed containing about 453 g (1 Ib) of activated carbon (Calgon Corp.,
Filtrasorb-300 or equivalent).
7.1.1.1 A water purification system (Millipore Super-Q or equivalent) may
be used to generate reagent water.
7.1.1.2 Reagent water may also be prepared by boiling water for 15
minutes. Subsequently, while maintaining the temperature at
90 °C, bubble a contaminant-free inert gas through the water for
one hour. While still hot, transfer the water to a narrow-mouth
screw-cap bottle and seal with a Teflon-lined septum and cap.
7.1.2 Methanol - pesticide quality or equivalent
7.2 Standards
7.2.1 Introduction
The Contractor must provide all standards to be used with this
contract. These standards may be used only after they have been
certified according to the procedure in Exhibit E. The Contractor
must be able to verify that the standards are certified.
Manufacturer's certificates of analysis must be retained by the
Contractor and presented upon request.
7.2.2 Stock Standard Solutions
7.2.2.1 Stock standard solutions may be purchased or may be prepared in
methanol from pure standard materials.
7.2.2.2 Prepare stock standard solutions by placing about 9.8 mL of
methanol into a 10 mL ground-glass stoppered volumetric flask.
Allow the flask to stand, unstoppered, for about 10 minutes, or
until all alcohol-wetted surfaces have dried. Weigh the flask to
the nearest 0.1 mg.
7.2.2.3 Add the assayed reference material as described below.
7.2.2.3.1 If the compound is a liquid, using a 100 /uL syringe,
immediately add two or more drops of assayed reference material
to the flask, then reweigh. The liquid must fall directly into
the alcohol without contacting the neck of the flask.
7.2.2.3.2 If the compound is a gas at room temperature, fill a 5 mL
valved gas-tight syringe with the reference standard to the
5 mL mark. Lower the needle to 5 mm above the methanol
meniscus. Slowly introduce the reference standard above the

Reagents and Standards
surface of the liquid. The gas will rapidly dissolve in the
methanol.
7.2.2.3.3 The procedure in Section 7.2.2.3.2 may also be accomplished by
using a lecture bottle equipped with a Hamilton Lecture Bottle
Septum (#86600). Attach Teflon tubing to the side-arm relief
valve and direct a gentle stream of the reference standard into
the methanol meniscus.
7.2.2.3.4 Reweigh, dilute to volume, stopper, then mix by inverting the
flask several times. For non-gaseous compounds, calculate the
concentration in micrograms per microliter from the net gain in
weight. When compound purity is assayed to be 97.0 percent or
greater, the weight may be used without correction to calculate
the concentration of the stock standard. If the compound
purity is assayed to be less than 97.0 percent, the weight must
be corrected when calculating the concentration of the stock
solution. See Exhibit E (Analytical Standards Requirements).
For gaseous compounds, calculate the concentration in
micrograms per microliter, using the Ideal Gas Law, taking into
account the temperature and pressure conditions within the
laboratory.
7.2.2.3.5 Prepare fresh stock standards every two months for gases or for
reactive compounds such as styrene. All other stock standards
for non-gases/non-reactive purgeable compounds must be replaced
after six months, or sooner if the standard has degraded or
evaporated.
7.2.3 Secondary Dilution Standards
7.2.3.1 Using stock standard solutions, prepare secondary dilution
standards in methanol that contain the compounds of interest,
either singly or mixed together. Secondary dilution standard
solutions should be prepared at concentrations that can be easily
diluted to prepare wording standard solutions.
7.2.3.2 Prepare fresh secondary dilution standards for gases and for
reactive compounds such as styrene every month, or sooner, if
standard has degraded or evaporated. Secondary dilution standards
for the other purgeable compounds must be replaced after six
months, or sooner, if standard has degraded or evaporated.

solution of BFB if a 1 jiL injection volume is used.
7.2.4.5 Calibration Standard Solution
Prepare a calibration standard solution containing all of the
purgeable target compounds in methanol. The recommended
concentration of the target compounds is 100 /tg/mL. Prepare fresh
calibration standard solutions weekly, or sooner if solutions have
degraded or evaporated.
7.2.4.6 Initial and Continuing Calibration Standards
7.2.4.6.1 Prepare five aqueous initial calibration standard solutions
containing all of the purgeable target compounds and system
monitoring compounds at 10, 20, 50, 100 and 200 /xg/L levels.
It is required that all three xylenp isomers (o-, m-, and p-
xylene) be present in the calibration standards at
concentrations of each isomer equal to that of the other target
compounds (i.e., 10, 20, 50, 100 and 200 /Kj/L). Similarly, the
cis and trans isomers of 1,2-dichloroethene must both be
present in the standards at concentrations of each isomer equal
to that of the other target compounds.
7.2.4.6.2 Aqueous calibration standards may be prepared in a volumetric

9.2 GC/MS Calibration (Tuning) and Ion Abundance
9.2.1 Summary of GC/MS Performance Check
9.2.1.1 The GC/MS system must be tuned to meet the manufacturer's
spe ifications, using a suitable caiibrant such as perfluoro-tri-
n-butylamine (FC-43) or perfluorokerosene (PFK). The mass
calibration and resolution of the GC/MS system are verified by the
analysis of the instrument performance check solution (Section
7.2.4.4).
9.2.1.2 Prior to the analysis of any samples, including MS/MSDs, blanks,
or calibration standards, the Contractor must establish that the
GC/MS system meets the mass spectral ion abundance criteria for
the instrument performance check solution containing BFB.
9.2.2 Frequency of GC/MS Performance Check
The instrument performance check solution must be injected once at
the beginning of each 12-hour period, during which samples or
standards are to be analyzed. The twelve (12) hour time period for
GC/MS instrument performance check (BFB), standards calibration
(initial or continuing calibration criteria), blank and sample
analysis begins at the moment of injection of the BFB analysis that
the laboratory submits as documentation of a compliant instrument
performance check. The time period ends after twelve (12) hours have
elapsed according to the system clock.

GC/MS Calibration and Ion Abundance
9.2.3 Procedure for GC/MS Performance check
9.2.3.1 The analysis of the instrument performance check solution may be
performed as follows:
• As an injection of up to 50 ng of BFB into the GC/MS.
• By adding 50 ng of BFB to 5 mL of reagent water and analyzing
the resulting solution as if it were an environmental sample
(see Section 10).
9.2.3.2 The instrument performance check solution must be analyzed alone
without calibration standards. NOTE: The calibration standards
contain BFB as a system monitoring compound (SMC).
9.2.4 Technical Acceptance Criteria for GC/MS Performance Check
9.2.4.1 The mass spectrum of BFB must be acquired in the following manner.
Three scans (the peak apex scan and the scans immediately
preceding and following the apex) are acquired and averaged.
Background subtraction is required, and must be accomplished using
a single scan no more than 20 scans prior to the elution of BFB.
Do not background subtract part of the BFB peak.
9.2.4.2 NOTE: All subsequent standards, samples, MS/MSD, and blanks
associated with a BFB analysis must use identical mass
spectrometer instrument conditions.
9.2.4.3 The analysis of the instrument performance check solution must
meet the ion abundance criteria given in Table 1.
9.2.5 Corrective Action for GC/MS Performance Check
9.2.5.1 If the BFB technical acceptance criteria are not met, retune the
GC/MS system. It may also be necessary to clean the ion source,
clean the quadrupole rods, or take other corrective actions to
achieve the technical acceptance criteria.
9.2.5.2 BFB technical acceptance criteria must, be met before any
standards, samples, including MS/MSDs or required blanks are
analyzed. Any samples or required blanks analyzed when tuning
technical acceptance criteria have not been met will require
reanalysis at no additional cost to the Agency.
9.3 Initial Calibration
9.3.1 Summary of Initial Calibration
Prior to the analysis of samples and required blanks, and after the
instrument performance check solution criteria have been met, each
GC/MS system must be calibrated at five concentrations
D-22/VOA OLM03.1

Initial Calibration
to determine instrument sensitivity and the linearity of GC/MS
response for the purgeable target compounds.
9.3.2 Frequency of Initial Calibration
9.3.2.1 Each GC/MS system must be calibrated upon award of the contract,
whenever the Contractor takes corrective action which may change
or affect the initial calibration criteria (e.g., ion source
cleaning or repair, column replacement, etc.), or if the
continuing calibration acceptance criteria have not been met.
9.3.2.2 If time remains in the 12-hour time period after meeting the
technical acceptance criteria for the initial calibration, samples
may be analyzed. It is not necessary to analyze a continuing
calibration standard if the initial calibration standard that is
the same concentration as the continuing calibration standard
meets the continuing calibration technical acceptance criteria. A
method blank is required. Quantify all sample and quality control
sample results, such as internal standard area response change and
retention time shift, against the initial calibration standard
that is the same concentration as the continuing calibration
standard.
9.3.3 Procedure for Initial Calibration
9.3.3.1 Assemble a purge and trap device that meets the specifications in
Section 6.4. Condition the device as described in Section 9.1.1.
9.3.3.2 Connect the purge and trap device to the gas chromatograph. The
gas chromatograph must be operated using temperature and flow rate
parameters equivalent to those in 9.1.2.
9.3.3.3 Add 10 ^L of the internal standard solution (Section 7.2.4.3) to
each of the five aqueous calibration standard solutions containing
the system monitoring compounds (Section 7.2.4.6) for a
concentration of 50 /xg/L at time of purge. Analyze each
calibration standard according to Section 10.
9.3.3.4 Separate initial and continuing calibrations must be performed for
water samples and low level soil/sediment samples (unheated purge
vs. heated purge). Extracts of medium level soil/sediment samples
may be analyzed using the calibrations of water samples.
9.3.4 Calculations for Initial Calibration
9.3.4.1 Calculate the relative reponse factor (RRF) for each volatile
target and system monitoring compound using equation 1. The
primary characteristic ions used for quantitation are listed in
Table 2 and Table 4. Assign the target compounds, and system
monitoring compound to an internal standard according to Table 3.
If an interference prevents the use of a primary ion for a given
internal standard, use a secondary ion listed in Table 4. NOTE:

Unless otherwise stated, the area response of the primary
characteristic ion is the quantitation ion.

Where,
Ax = Area of the characteristic ion (EICP) for the compound to
be measured (see Table 2)
Ajs = Area of the characteristic ion (EICP) for the specific
internal standard (see Tables 3 and 4)
CjS = Concentration of the internal standard
Cx = Concentration of the compound to be measured
9.3.4.2 Calculating the relative response factor of the xylenes and the
cis and trans isomers of 1,2-dichloroethene requires special
attention. On packed columns, o- and p-xylene isomers co-elute.
On capillary columns, the m- and p-xylene isomers co-elute.
Therefore, when calculating the relative response factor in the
equation above, use the area response (Ax) and concentration (Cx)
of the peak that represents the single isomer on the GC column
used for analysis.
9.3.4.3 For the cis and trans isomers of 1,2-dichloroethene which may co-
elute on packed columns but not on capillary columns, both isomers
must be present in the standards. If the two isomers co-elute,
use the area of the co-eluting peak and the total concentration of
the two isomers in the standard to determine the relative response
factor. If the two isomers do not co-elute, sum the areas of the
two peaks and the concentrations of the two isomers in the
standard to determine the relative response factor.
9.3.4.4 The mean relative response factor (RRF) must be calculated for all
compounds.

9.3.5.1 All initial calibration standards must be analyzed at the
concentration levels described in Section 7.2.4.6.1, and at the
frequency described in Section 9.3.2 on a GC/MS system meeting the
BFB technical acceptance criteria.
9.3.5.2 The relative response factor (RRF) at each calibration
concentration for each purgeable target and system monitoring
compound must be greater than or equal to the compound's minimum
acceptable response factor listed in Table 5.
9.3.5.3 The %RSD for each target or system monitoring compound listed in
Table 5 must be less than or equal to that value listed.
9.3.5.4 Up to two compounds may fail the criteria listed in Sections
9.3.5.2 and 9.3.5.3 and still meet the minimum response factor and
%RSD requirements. However, these compounds must have a minimum
RRF greater than or equal to 0.010, and the %RSD must be less than
or equal to 40.0 percent.
9.3.5.5. Excluding those ions in the solvent front, the combined xylenes
and 1,2-Dichloroethenes in the 200 /*g/L standard, no quantitation
ion may saturate the detector. Follow the manufacturer's
instrument operating manual to determine how saturation is
indicated for your instrument.
9.3.6 Corrective Action for Initial Calibration
9.3.6.1 If the initial calibration technical acceptance criteria are not
met, inspect the system for problems. It may be necessary to
clean the ion source, change the column, service the purge and
trap device or take other corrective actions to achieve the
technical acceptance criteria.

before any samples or required blanks are analyzed. Any samples
including MS/MSD or required blanks analyzed when initial
calibration technical acceptance criteria have not been met will
require reanalysis at no additional cost to the Agency.
9.4 Continuing Calibration
9.4.1 Summary of Continuing Calibration
Prior to the analysis of samples and required blanks and after BFB
and initial calibration acceptance criteria have been met, each GC/MS
system must be routinely checked by analyzing a continuing
calibration standard containing all the purgeable target and system
monitoring compounds to ensure that the instrument continues to meet
the instrument sensitivity and linearity requirements of the SOW.
9.4.2 Frequency of Continuing Calibration
9.4.2.1 A check of the calibration curve must be performed once every 12
hours (see Section 9.2.2 for the definition of the 12-hour time
period) . If time remains in the 12-hour time period after meeting
the technical acceptance criteria for the initial calibration,
samples may be analyzed. It is not necessary to analyze a
continuing calibration standard if the initial calibration
sta iard that is the same concentration as the continuing
calibration standard meets the continuing calibration technical
acceptance criteria. A method blank is required. Quantify all
sample results against the initial calibration standard that is
the same concentration as the continuing calibration standard (50
9.4.2.2 If time does not remain in the 12-hour period beginning with the
injection of the instrument performance check solution, a new
injection of the instrument performance check solution must be
made. If the new injection meets the ion abundance criteria for
BFB, then a continuing calibration standard may be injected.
9.4.3 Procedure for Continuing Calibration
9.4.3.1 Set up the purge and trap GC/MS system per the requirements in
Section 9.1.1.
9.4.3.2 Add 10 /xL of internal standard solution (Section 7.2.4.3) to the 5
mL syringe or volumetric flask containing the continuing
calibration standard (Section 7.2.4.6). Analyze the continuing
calibration standard according to Section 10.

frequency described in Section 9.4.2 on a GC/MS system meeting the
BFB and initial calibration technical acceptance criteria.
9.4.5.2 The relative response factor (RRF) for each purgeable target and

10.0 PROCEDURE
10.1 Sample Preparation
10.1.1 If insufficient sample amount (less than 90% of the required amount)
is received to perform the analyses, the Contractor shall contact SMO
to apprise them of the problem. SMO will contact the Region for
instructions. The Region will either require that no sample analyses
be performed or will require that a reduced volume be used for the
sample analysis. No other changes in the analyses will be permitted.
The Contractor shall document the Region's decision in the SDG
Narrative.
10.1.2 If multiphase samples (e.g., two-phase liquid sample, oily
sludge/sandy soil sample) are received by the Contractor, the
Contractor shall contact SMO to apprise them of the type of sample
received. SMO will contact the Region. If all phases of the sample
are amenable to analysis, the Region may require the Contractor to do
the following:
• Mix the sample and analyze an aliquot from the homogenized
sample.
• Separate the phases of the sample and analyze each phase
separately. SMO will provide EPA sample numbers for the
additional phases, if required.
• Separate the phases, and analyze one or more of the phases, but
not all of the phases. SMO will provide EPA sample numbers for
the additional phases, if required.
• Do not analyze the sample.
10.1.2.1 If all of the phases are not amenable to analysis (i.e., outside
scope), the Region may require the Contractor to do tae following:
• Separate the phases and analyze the phase(s) that is amenable
to analysis. SMO will provide EPA sample numbers for the
additional phases, if required.
• Do not analyze the sample.
10.1.2.2 No other changes in the analyses will be permitted. The
Contractor shall document the Region's decision in the SDG
Narrative.
10.1.3 Water Samples
10.1.3.1 All water samples must be allowed to warm to ambient temperature
before analysis.
10.1.3.2 Prior to the analysis of samples, establish the appropriate purge

analyze the instrument performance check solution (9.2), and
calibrate the GC/MS system according to Sections 9.3 through
9.4.6.
10.1.3.3 If time remains in the 12-hour period (as described in Section
9.3.2), samples may be analyzed without analysis of a continuing
calibration standard.
10.1.3.4 If time does not remain in the 12-hour period since the injection
of the instrument performance check solution, both the instrument
performance check solution and the continuing calibration standard
must be analyzed before sample analysis may begin (see Section
9.4.2) .
10.1.3.5 Adjust the purge gas (helium) flow rate to 25-40 mL/minute.
Variations from this flow rate may be necessary to achieve better
purging and collection efficiencies for some compounds,
particularly chloromethane and bromoform.
10.1.3.6 Remove the plunger from a 5 mL syringe and attach a closed syringe
valve. Open the sample or standard bottle which has been allowed
to come to ambient temperature, and carefully pour the sample into
the syringe barrel to just short of overflowing. Replace the
syringe plunger and compress the sample. Open the syringe valve
and vent any residual air while adjusting the sample volume to 5
mL. This process of taking an aliquot destroys the validity of
the sample for future analysis so, if there is only one VOA vial,
the analyst must fill a second syringe at this time to protect
against possible loss of sample integrity. This second sample is
maintained only until such time as the analyst has determined that
the first sample has been analyzed properly. Filling one 5 mL
syringe would allow the use of only one syringe. If an analysis
is needed from the second 5 mL syringe, it must be performed
within 24 hours. Care must also be taken to prevent air from
leaking into the syrin-,3.
10.1.3.7 Add 10 /xL of the system monitoring compound spiking solution
(Section 7.2.4.1) and 10 ;tL of the internal standard spiking
solution (Section 7.2.4.3) through the valve bore of the syringe,
then close the valve. The system monitoring compounds and
internal standards may be mixed and added as a single spiking
solution. The addition of 10 /tL of the system monitoring compound
spiking solution to 5 mL of sample is equivalent to a
concentration of 50 /xg/L of each system monitoring compound.
10.1.3.8 Attach the syringe-syringe valve assembly to the syringe valve on
the purging device. Open the syringe valves and inject the sample
into the purging chamber.
10.1.3.9 Close both valves and purge the sample for 11.0 ± 0.1 minutes at
ambient temperature.

Exhibit D Volatiles — Section 10
Procedure
Sample Preparation
10.1.3.10 At the conclusion of the purge time, attach the trap to the
chromatograph, adjust the device to the desorb mode, and begin the
gas chromatographic temperature program. Concurrently, introduce
the trapped materials to the gas chromatographic column by rapidly
heating the trap to 180 °C while backflushing the trap with an
inert gas between 20 and 60 mL/minute for four minutes.
10.1.3.11 While the trap is being desorbed into the gas chromatograph, empty
the purging chamber. Wash the chamber with a minimum of two 5 mL
flushes of reagent water to avoid carryover of target compounds.
For samples containing large amounts of water-soluble materials,
suspended solids, high-boiling compounds, or high purgeable
levels, it may be necessary to wash out the purging device with a
detergent solution between analyses, rinse it with distilled
water, and then dry it in an oven at 105 °C.
10.1.3.12 After desorbing the sample for four minutes, recondition the trap
by returning the purge and trap device to the purge mode. Wait 15
seconds, then close the syringe valve on the purging device to
begin gas flow through the trap. The trap temperature should be
maintained at 180 °C. Trap temperatures up to 220 °C may be
employed. However, the higher temperature will shorten the useful
life of the trap. After approximately seven minutes, turn off the
trap heater and open the syringe valve to stop the gas flow
through the trap. When cool, the trap is ready for the next
sample.
10.1.4 Low Level Soil/Sediment Samples
10.1.4.1 The Contractor must determine whether a soil/sediment sample
should be analyzed by the low or medium method. It is the
responsibility of the Contractor to analyze the sample at the
correct level.
10.1.4.2 Three approaches may be taken to determine whether the low level
or medium level method must be followed.
• Assume the sample is low level and analyze a 5 g sample.
• Use the X factor calculated from the hexadecane screen
(Appendix A) to determine the appropriate method for analysis.
• Use an in-house laboratory screening procedure. This
procedure must be documented and available for review during
on-site laboratory evaluation or when requested by the
Technical Project Officer or Administrative Project Officer.
10.1.4.3 If the on column concentration of any TCL compound exceeds the
initial calibration range from the analysis of 5 g sample, a
smaller sample size must be analyzed. However, the smallest
sample size permitted is 0.5 g. If smaller than 0.5 g sample size
is needed to prevent the on column concentration of TCL compounds
D-31/VOA OLM03.0

Exhibit D Volatiles — Section 10
Procedure
Sample Preparation
from exceeding the initial calibration range, the medium level
method must be used.
10.1.4.4 The low level soil/sediment method is based on a heated purge of a
soil/sediment sample mixed with reagent water containing the
system monitoring compounds and the internal standards. Analyze
all MS/MSD samples, blanks and standards under the same conditions
as the samples.
10.1.4.5 Use 5 grams of sample, or use the X Factor (Appendix A) or your
in-house screening procedure to determine the sample size for
purging.
10.1.4.6 Prior to the analysis of samples, establish the appropriate purge
and trap GC/MS operating conditions, as outlined in Section 9.1,
analyze the instrument performance check solution (9.2), and
calibrate the GC/MS system according to Sections 9.3 through
9.4.6. This should be done prior to the preparation of the sample
to avoid loss of volatiles from standards and sample. A heated
purge calibration curve must be prepared and used for the
quantitation of all samples analyzed with the low level method.
Follow the initial and daily calibration instructions (9.3.3 and
9.4.3), but increase the purge temperature to 40 °C.
10.1.4.7 To prepare the reagent water containing the system monitoring
compounds and the internal standards, remove the plunger from a 5
mL "Luerlok" type syringe equipped with a syringe valve and fill
until overflowing with reagent water. Replace the plunger and
compress the water to vent trapped air. Adjust the volume to 5
mL. Add 10 jitL of the system monitoring compound spiking solution
and 10 /xL of the internal standard solution to the syringe through
the valve. NOTE: Up to 10 mL of reagent water may be added to a
soil sample to increase purge gas/sample interaction. All soil
samples including MS and MSD, standards, and blanks within an SDG
must have the same amount of reagent water added. Do not
increase/change the amount of system monitoring compound and
internal standard solution added.
10.1.4.8 The sample (for volatile organics) is defined as the entire
contents of the sample container. Do not discard any supernatant
liquids. Mix the contents of the sample container with a narrow
metal spatula. Weigh 5 g or the amount determined in using the
screening procedure in Appendix A or an in-house screening
procedure into a tared purge device. Use a top loading balance.
Note and record the actual weight to the nearest 0.1 g.
10.1.4.9 Add the spiked reagent water to the purge device and connect the
device to the purge and trap system.
10.1.4.10 NOTE: Prior to the attachment of the purge device, the steps in
Sections 10.1.4.7 and 10.1.4.9 above must be performed rapidly to

a laboratory free of solvent fumes.
10.1.4.11 Heat the sample to 40 °C ±1 °C and purge the sample for 11.0 ±
0.1 minutes.
10.1.4.12 Proceed with the analysis as outlined in Sections 10.1.3.9 through
10.1.3.12.
10.1.5 Medium Level Soil/Sediment Samples
10.1.5.1 The medium level soil/sediment method is based on extracting the
soil/sediment sample with methanol. An aliquot of the methanol
extract is added to reagent water containing the system monitoring
compounds and the internal standards. The reagent water
containing the methanol extract is purged at ambient temperature.
When using the screening method in Appendix A, all samples with an
X Factor > 1.0 should be analyzed by the medium level method.
10.1.5.2 Prior to the analysis of samples, establish the appropriate purge
and trap GC/MS operating conditions, as outlined in Section 9.1,
analyze the instrument performance check solution (9.2), and
calibrate the GC/MS system according to Sections 9.3 through
9.4.6. This should be done prior to the addition of the methanol
extract to reagent water. Because the methanol extract and
reagent water mixture is purged at ambient temperature, the
instrument performance check, initial calibration, and continuing
calibration for water samples may be used for analyses of medium
level soil/sediment sample extracts.
10.1.5.3 The sample (for volatile organics) is defined as the entire
contents of the sample container. Do not discard any supernatant
lig_uids. Mix the contents of the sample container with a narrow
metal spatula. Weigh 4 g (wet weight) into a tared 15 mL vial.
Use a top loading balance. Note and record the actual weight to
the nearest 0.1 g.
10.1.5.4 Quickly add 10 mL of methanol to the vial. Cap and shake for 2
minutes.
10.1.5.5 NOTE: The steps in Sections 10.1.5.3 and 10.1.5.4 must be
performed rapidly to avoid loss of volatile organics. These steps
must be performed in a laboratory free of solvent fumes.
10.1.5.6 Let the solution settle. Then, using a disposable pipette,
transfer approximately 1 mL of extract into a GC vial for storage.
The remainder may be discarded. The 1 mL extract may be stored in
the dark at less than 4 °C but not greater than 6 °C prior to the
analysis.
10.1.5.7 Table 6 can be used to determine the volume of methanol extract to
add to the 5 mL of reagent water for analysis. If the hexadecane
screen procedure (Appendix A) was followed, use the estimated

the appropriate volume. Otherwise, estimate the concentration
range of the sample from the low level analysis or from the in-
house screening procedure to determine the appropriate volume.
10.1.5.8 Remove the plunger from a 5 mL "Luerlok" type syringe equipped
with a syringe valve and fill until overflowing with reagent
water. Replace the plunger and compress the water to vent trapped
air. Adjust the volume to 4.9 mL. Pull the plunger back to 5 mL
to allow volume for the addition of sample and standards. Add 10
/iL of system monitoring compound and 10 /xL of the internal
standard solution. Also add the volume of methanol extract
determined in Section 10.1.5.7 and a volume of clean methanol to
total 100 /xL (excluding methanol in system monitoring/internal
standard solutions).
10.1.5.9 Attach the syringe-syringe valve assembly to the syringe valve on
the purge device. Open the syringe valve and inject the
water/methanol sample into the purging chamber.
10.1.5.10 Proceed with the analysis as outlined in Section 10.1.3.9 through
10.1.3.12.
10.1.6 Sample Dilutions
10.1.6.1 For medium level soil/sediment analyses, the purgeable organics
screening procedure (Appendix A), if used, will show the
approximate concentrations of major sample components. If a
dilution of the sample was indicated, this dilution shall be made
just prior to GC/MS analysis of the sample. All steps in the
dilution procedure must be performed without delays until the
point at which the diluted sample is in a gas tight syringe.
10.1.6.2 If the on-column concentration of any compound in any sample
exceeds the initial calibration range, a new aliquot of that
sample must be diluted and purged. Guidance in performing
dilutions and exceptions to this requirement are given in Sections
10.1.6.3 through 10.1.6.12.
10.1.6.3 Use the results of the original analysis to determine the
approximate dilution factor required to get the largest analyte
peak within the initial calibration range.
10.1.6.4 The dilution factor chosen should keep the response of the largest
analyte peak for a target compound in the upper half of the
initial calibration range of the instrument.
10.1.6.5 All dilutions for water samples are made in volumetric flasks
(10 mL to 100 mL).
10.1.6.6 Select the volumetric flask that will allow for the necessary
dilution. Intermediate dilutions may be necessary for extremely
large dilutions.

Procedure
pH Determination
10.1.6.7 Calculate the approximate volume of reagent water which will be
added to the volumetric flask selected and add slightly less than
this quantity of reagent water to the flask.
10.1.6.8 For water samples, inject the proper aliquot from the syringe
prepared in Section 10.1.3.6 into the volumetric flask. Aliquots
of less than 1 mL increments are prohibited. Dilute the flask to
the mark with reagent water. Cap the flask, invert, and shake
three times.
10.1.6.9 Fill a 5 mL syringe with the diluted sample as in Section
10.1.3.6.
10.1.6.10 If this is an intermediate dilution, use it and repeat the above
procedure to achieve larger dilutions.
10.1.6.11 Do not submit data for more than two analyses, i.e., the original
sample and one dilution, or, from the most concentrated dilution
analyzed and one further dilution.
10.1.6.12 For total xylenes, where three isomers are quantified as two
peaks, the calibration of each peak should be considered
separately, i.e., a diluted analysis is not required for total
xylenes unless the concentration of the peak representing the
single isomer exceeds 200 ^g/L (/xg/kg for so\ls/sediment) or the
peak representing the two co-eluting somers on the GC column
exceeds 400 /xg/L (/xg/kg for soils/sediment) . Similarly, if the
cis and trans isomers of 1,2-dichloroethene co-elute, a diluted
analysis is not required unless the concentration of the co-
eluting peak exceeds 400 /ug/L (/xg/kg for soils/sediment). If the
two isomers do not co-elute, a diluted analysis is not required
unless the concentration of either peak exceeds 200 /xg/L (tig/kg
for soils/sediment).
10.2 pH Determination (Water Samples)
Once the sample aliquots have been taken from the VOA vial, the pH of
the water sample must be determined. The purpose of the pH
determination is to ensure that all VOA samples were acidified in the
field. Test the pH by placing one or two drops of sample on the pH
paper (do not add pH paper to the vial). Record the pH of each sample,
and report these data in the SDG Narrative, following the instructions
in Exhibit B. No pH adjustment is to be performed by the Contractor.

Qualitative Identification
11.0 DATA ANALYSIS AND CALCULATIONS
11.1 Qualitative Identification
ll.l.i Identification of Target Compounds
11.1.1.1 The compounds listed in the Target Compound List (TCL) in Exhibit
C (Volatiles) shall be identified by an analyst competent in the
interpretation of mass spectra (see Exhibit A, Section 4.3.1) by
comparison of the sample mass spectrum to the mass spectrum of a
standard of the suspected compound. Two criteria must be
satisfied to verify the identifications: (1) elution of the sample
component at the same GC relative retention time as the standard
component, and (2) correspondence of the sample component and
standard component mass spectra.
11.1.1.2 For establishing correspondence of the GC relative retention time
(RRT), the sample component RRT must compare within ±0.06RRT
units of the RRT of the standard component. For reference, the
standard must be run in the same 12-hour time period as the
sample. If samples are analyzed during the same 12-hour time
period as the initial calibration standards, use the RRT values
from the 50 /xg/L standard. If co-elution of interfering
components prohibits accurate assignment of the sample component
RRT from the total ion chromatogram, the RRT should be assigned by
usir extracted ion current profiles for ions unique to the
component of interest.
11.1.1.3 For comparison of standard and sample component mass spectra, mass
spectra obtained on the Contractor's GC/MS are required. Once
obtained, these standard spectra may be used for identification
purposes, only if the Contractor's GC/MS meets the daily
instrument performance requirements for BFB. These standard
spectra may be obtained from the run used to obtain reference
RRTs.
11.1.1.4 The requirements for qualitative verification by comparison of
mass spectra are as follows:
• All ions present in the standard mass spectra at a relative
intensity greater than 10.0 percent (most abundant ion in the
spectrum equals 100.0 percent) must be present in the sample
spectrum.
• The relative intensities of ions specified above must agree
within ± 20.0 percent between the standard and sample spectra.
(Example: For an ion with an abundance of 50.0 percent in the
standard spectra, the corresponding sample abundance must be
between 30.0 and 70.0 percent).
• Ions greater than 10.0 percent in the sample spectrum but not
present in the standard spectrum must be considered and
D-37/VOA OLM03.0

Exhibit D Volatiles — Section 11
Data Analysis and Calculations
Qualitative Identification
accounted for by the analyst making the comparison. In
Exhibit A, Task II, the verification process should favor
false positives. All compounds meeting the identification
criteria must be reported with their spectra. For all
compounds below the CRQL, report the actual value followed by
a "J", e.g., "3J".
11.1.1.5 If a compound cannot be verified by all of the criteria in
11.1.1.4, but in the technical judgment of the mass spectral
interpretation specialist, the identification is correct, then the
Contractor shall report that identification and proceed with
quantitation in Section 11.2.
11.1.2 Identification of Non-Target Compounds
11.1.2.1 A library search shall be executed for non-target sample
components for the purpose of tentative identification. For this
purpose, the NIST/EPA/NIH (May 1992 release or later) and/or Wiley
(1991 release or later), or equivalent mass spectral library,
shall be used.
11.1.2.2 Up to 30 organic compounds of greatest apparent concentration not
listed in Exhibit C for the volatile and semivolatile organic
fraction, excluding the system monitoring compounds and internal
standard compounds, shall be tentatively identified via a forward
search of the NIST/EPA/NIH (May 1992 release or later) and/or
Wiley (1991 release or later), or equivalent mass spectral
library. The following are not to be reported: 1) Substances with
responses less than 10 percent of the internal standard (as
determined by inspection of the peak areas or height), 2)
Substances which elute earlier than 30 seconds before the first
purgeable compound listed in Exhibit C (Volatiles) or three
minutes after the last purgeable compound listed in Exhibit C
{Volatiles) has eluted are not required to be searched in this
fashion, 3) Carbon dioxide, and 4) Semivolatile TCL compounds
listed in Exhibit C). Only after visual comparison of sample
spectra with the nearest library searches will the mass spectral
interpretation specialist assign a tentative identification.
11.1.2.3 NOTE: Computer generated library search routines must not use
normalizations which would misrepresent the library or unknown
spectra when compared to each other.
11.1.2.4 Guidelines for making tentative identification:
• Relative intensities of major ions in the reference spectrum
(ions greater than 10.0 percent of the most abundant ion)
should be present in the sample spectrum.
• The relative intensities of the major ions should agree within
±20.0 percent. (Example: For an ion with an abundance of
50.0 percent of the standard spectra, the corresponding sample
ion abundance must be between 30.0 and 70.0 percent.)
D-38/VOA OLM03.1

Exhibit D Volatiles — Section 11
Data Analysis and Calculations
Calculations
• Molecular ions present in reference spectrum should be present
in sample spectrum.
• Ions present in the sample spectrum but not in the reference
spectrum should be reviewed for possible background
contamination or presence of co-eluting compounds.
• Ions present in the reference spectrum but not in the sample
spectrum should be reviewed for possible subtraction from the
sample spectrum because of background contamination or co-
eluting compounds. Data system library reduction programs can
sometimes create these discrepancies.
11.1.2.5 If, in the technical judgment of the mass spectral interpretation
specialist, no valid tentative identification can be made, the
compound should be reported as unknown. The mass spectral
specialist should give additional classification of the unknown
compound, if possible (i.e., unknown aromatic, unknown
hydrocarbon, unknown acid type, unknown chlorinated compound) . If
probable molecular weights can be distinguished, include them.
11.2 Calculations
11.2.1 Target Compounds
11.2.1.1 Target compounds identified shall be quantified by the internal
standard method using the equations below. The internal standard
used shall be that which is assigned in Table 3. The relative
response factor (RRF) from the continuing calibration standard is
used to calculate the concentration in the sample.

samples for volatiles by this method is defined as the ratio

The dilution factor is equal to 1.0 in all cases other than
those requiring dilution of the sample methanol extract

(Section .10.1.5.7) is S12.5. The factor of 1,000 in the
numerator converts the value of Vt from mL to jtL.

Data Analysis and Calculations

11.2.1.5 For water, low level and medium level soil/sediment samples,
xylenes (o-,m- and p-isomers) are to be reported as xylenes
(total). Because the o- and p-xylene isomers co-elute on packed
columns, and the m- and p-xylene isomers co-elute on capillary
columns, special attention must be given to the quantitation of
the xylenes. The relative response factor (RRF) determined in
Section 9.4.4 is based on the peak that represents the single
isomer on the GC column used (m-xylene on packed columns, o-xylene
on capillary columns). In quantitating sample concentrations,
use the areas on both peaks and the RRF from Section 9.4.4. The
areas of the two peaks may be summed, and the concentration
determined, or the concentration represented by each of the two
peaks may be determined separately, and then summed. It is
required that all three xylene isomers be present in the initial
and continuing calibration standards.
11.2.1.6 The cis and trans stereo isomers of 1,2-dichloroethene are to be
reported as 1,2-dichloroethene (total). If the two isomers co-
elute on the GC column used for analysis, use the area of the co-
eluting peaks and the RRF determined in Section 9.4.4 to calculate
the concentration. If the isomers do not co-elute, use the single
RRF values determined in Section 9.3.4 to calculate the
concentration.
11.2.1.7 Secondary ion quantitation is allowed only when there are sample
matrix interferences with the primary ion. If secondary ion
quantitation is performed, document the reasons in the SDG
Narrative. A secondary ion cannot be used unless a relative
response factor is calculated using the secondary ion.
11.2.1.8 The requirements listed in 11.2.1.9 and 11.2.1.10 apply to all
standards, samples including MS/MSDs, and blanks.
11.2.1.9 It is expected that situations will arise where the automated
quantitation procedures in the GC/MS software provide
inappropriate quantitations. This normally occurs when there is
compound co-elution, baseline noise, or matrix interferences. In
these circumstances the Contractor must perform a manual
quantitation. Manual quantitations are performed by integrating
the area of the quantitation ion of the compound. This
integration shall only include the area attributable to the
specific TCL compound. The area integrated shall not include
baseline background noise. The area integrated shall not extend
past the point where the sides of the peak intersect with the
baseline noise. Manual integration is not to be used solely to
meet QC criteria, nor is it to be used as a substitute for
corrective action on the chromatographic system. Any instances of
manual integration must be documented in the SDG Narrative.
11.2.1.10 In all instances where the data system report has been edited, or
where manual integration or quantitation has been performed, the

GC/MS operator must identify such edits or manual procedures by
initialing and dating the changes made to the report, and shall
include the integration scan range. In addition, a hardcopy
printout of the EICP of the quantitation ion displaying the manual
integration shall be included in the raw data. This applies to
all compounds listed in Exhibit C (Volatiles), internal standards
and system monitoring compounds.
11.2.2 Non-Target Compounds
11.2.2.1 An estimated concentration for non-target compounds tentatively
identified shall be determined by the internal standard method.
For quantitation, the nearest internal standard free of
interferences shall be used.
11.2.2.2 The formulas for calculating concentrations are the same as in
Sections 11.2.1.2, 11.2.1.3, and 11.2.1.4. Total area counts (or
peak heights) from the total ion chromatograms are to be used for
both the compound to be measured and the internal standard. A
relative response factor (RRF) of one (1) is to be assumed. The
resulting concentration shall be qualified as "J" (estimated, due
to lack of a compound-specific response factor), and "N"
(presumptive evidence of presence), indicating the quantitative
and qualitative uncertainties associated with this non-target
component. An estimated concentration must be calculated for all
ten itively identified compounds as /ell as those identified as
unknowns.

continuing calibration internal standard response and retention
times. For samples analyzed during the same 12-hour time period as
the initial calibration standards, compare the internal standard
responses and retention times against the 50 /xg/L calibration
standard. The extracted ion current profile (EICP) of the internal
standards must be monitored and evaluated for each sample, blank,
matrix spike and matrix spike duplicate.
11.3 Technical Acceptance Criteria for Sample Analysis
11.3.1 The samples must be analyzed on a GC/MS system meeting the BFB,
initial calibration, continuing calibration, and blank technical
acceptance criteria.
11.3.2 The sample must be analyzed within the contract holding time.
11.3.3 The sample must have an associated method blank meeting the blank
technical acceptance criteria.
11.3.4 The percent recovery of each of the system monitoring compounds in
the sample must be within the acceptance windows in Table 7.
11.3.5 The EICP area for each of the internal standards must be within the
inclusive range of -50.0 percent and +100.0 percent of the response
of the internal standards in the most recent continuing calibration
analysis.
11.3.6 The retention time shift for each of the internal standards must be
within ±0.50 minutes (30 seconds) between the sample and the most
recent continuing calibration standard analysis.
11.3.7 The relative retention time (RRT) of the system monitoring compound
in a sample must be within ±0.06 (RRT) units of its relative
retention time in the continuing calibration standard.
11.3.8 Excluding those ions in the solvent front, no ion may saturate the
detector. No target compound concentration may exceed the upper
limit of the initial calibration range unless a more diluted aliquot
of the sample is also analyzed according to the procedures in Section
10.1.6.
11.3.9 The Contractor must demonstrate that there is no carryover from a
contaminated sample before data from subsequent analyses may be
submitted. After a sample that contains a target compound at a level
exceeding the initial calibration range, the Contractor must either:
• Analyze an instrument blank immediately after the contaminated
sample. If an autosampler is used, an instrument blank must also
be analyzed using the same purge inlet that was used for the
contaminated sample. The instrument blanks must meet the
technical acceptance criteria for blank analysis (see Section
12.1.4), or
D-44/VOA OLM03.0
-------
Exhibit D Volatiles — Section 11
Data Analysis and Calculations
Corrective Action for Sample Analysis
• Monitor the sample analyzed immediately after the contaminated
sample for all compounds that were in the contaminated sample and
that exceeded the calibration range. The maximum contamination
criteria are as follows: the sample must not contain a
concentration above the CRQL for the target compounds that
exceeded the limits in the contaminated sample. If an auto
sampler is used, the next sample analyzed using the same purge
inlet that was used for the contaminated sample also must meet
the maximum contamination criteria. If the maximum criteria were
exceeded, then all samples affected by the carryover must be
reanalyzed at no additional cost to the Agency.
11.4 Corrective Action for Sample Analysis
11.4.1 Sample technical acceptance criteria must be met before data are
reported. Samples contaminated from laboratory sources or sample
results which failed to meet the sample technical acceptance criteria
require reanalysis at no additional cost to the Agency.
11.4.2 Corrective actions for failure to meet instrument performance checks,
initial and continuing calibration, and method blanks must be
completed before the analysis of samples.
11.4.3 Corrective action for system monitoring compounds and internal
standard compounds that fail to meet acceptance criteria.
11.4.3.1 If any of the system monitoring compounds and internal standard
compounds fail to meet acceptance criteria:
• Check all calculations, instrument logs, the system monitoring
compound and internal standard compound spiking solutions, and
the instrument operation. If the calculations were incorrect,
correct the calculations and verify that the system monitoring
compound recoveries and internal standard compound responses
meet acceptance criteria.
• If the instrument logs indicate that the incorrect amount of
system monitoring compound or internal standard compound
spiking solution was added, then reanalyze the sample after
adding the correct amount of system monitoring compound and
internal standard spiking solutions.
• If the system monitoring compound spiking solution or internal
standard compound spiking solution was improperly prepared,
concentrated, or degraded, re-prepare the solutions and
reanalyze the samples.
• If the instrument malfunctioned, correct the instrument
problem and reanalyze the sample. If the instrument
malfunction affected the calibration, recalibrate the
instrument before reanalyzing the sample. Verify that the
system monitoring compound recoveries meet acceptance
criteria.

11.4.3.2 If the above actions do not correct the problem, then the problem
may be due to a sample matrix effect. To determine if there was a
matrix effect, take the following corrective action steps:
• Reanalyze the sample. EXCEPTION: If system monitoring
compound recoveries or internal standard compound responses in
a sample used for a matrix spike or matrix spike duplicate
were outside the acceptance criteria, then it should be
reanalyzed only if system monitoring compound recoveries and
internal standard compound responses met acceptance criteria
in both the matrix spike and matrix spike duplicate analyses.
• If the system monitoring compound recoveries and the internal
standard compound responses meet the acceptance criteria in
the reanalyzed sample, then the problem was within the
Contractor's control. Therefore, submit data only from the
reanalysis.
• If the system monitoring compound recoveries and/or the
internal standard compound responses fail to meet the
acceptance windows in the reanalysis, then submit data from
both analyses. Distinguish between the initial analysis and
the reanalysis on all deliverables using the suffixes on

times/internal standard compounds retention times outside acceptance
criteria.
11.4.4.1 If the system monitoring compounds relative retention times or
internal standard compounds retention times are not within their
acceptance criteria, check the instrument for malfunctions. If
the instrument malfunctioned, correct the instrument problem and
reanalyze the sample. If the instrument malfunction affected the
calibration, recalibrate the instrument before reanalyzing the
samples.
11.4.4.2 If the above actions do not correct the problem, then the problem
may be due to a sample matrix effect. To determine if there was a
matrix effect, take the following corrective action steps:
• Reanalyze the sample. EXCEPTION: If the system monitoring
compounds relative retention times or internal standard
compounds retention times in a sample used for a matrix spike
or matrix spike duplicate were outside the acceptance
criteria, then it should be reanalyzed only if the system
monitoring compounds and internal standard compounds retention
times were within the acceptance criteria in both the matrix
spike and matrix spike duplicate analyses.
• If the system monitoring compounds relative retention times
and internal standard compounds retention times are within the
acceptance criteria, then the problem was within the

Blank Analyses
12.0 QUALITY CONTROL
12.1 Blank Analyses
12.1.1 Summary — There are three different types of blanks required by this
method.
12.1.1.1 METHOD BLANK - a volume of a clean reference matrix (reagent water
for water samples or a purified solid matrix for soil/sediment
samples) that is carried through the entire analytical procedure.
The volume or weight of the reference matrix must be approximately
equal to the volume or weight of samples associated with the
blank. The purpose of a method blank is to determine the levels
of contamination associated with the processing and analysis of
samples.
12.1.1.2 STORAGE BLANK - upon receipt of the first samples in an SDG, two
40.0 mL screw-cap volatile vials with a PTFE-faced silicone septum
are filled with reagent water (80 mL total). The vials are stored
with the samples in the SDG under the same conditions. After all
samples in the SDG have been analyzed, the storage blank is
analyzed. The storage blank indicates whether contamination may
have occurred during storage of samples.
12.1.1.3 INSTRUMENT BLANK - a 5.0 mL aliquot of reagent water that is
carried through the entire analytical procedure. Instrument
blanks are analyzed after a sample/dilution which contains a
target compound exceeding the initial calibration range. The
results from the instrument blank analysis indicate whether there
is contamination from a previous sample.
12.1.2 Frequency of Blank Analyses
12.1.2.1 The method blank must be analyzed at least once during every 12-
hour time period on eacn GC/MS system used for volatile analysis
(see Section 9.2.2 for the definition of the 12-hour time period).
12.1.2.2 The method blank must be analyzed after the continuing calibration
and before any samples, including matrix spike/matrix spike
duplicates, dilutions or storage blanks are analyzed. The method
blank must be analyzed after the initial calibration sequence if
samples are analyzed before the 12-hour period expires. A method
blank must be analyzed in each 12-hour time period in which
samples, including dilutions, matrix spikes/matrix spike
duplicates, and storage blanks are analyzed.
12.1.2.3 A minimum of one storage blank must be analyzed per SDG after all
samples for that SDG have been analyzed.
12.1.2.4 The Contractor must demonstrate that there is no carryover from
contaminated samples before data from subsequent analyses may be
used. Samples/dilutions may contain target compounds at levels
exceeding the initial calibration range. An instrument blank must

Quality Control
Blank Analyses
be analyzed after the sample that exceeds the calibration range
(also in the same purge inlet if an autosampler is used) or a
sample that meets the maximum contamination criteria in Section
11.3.8 must be analyzed. For these purposes, if the instrument
blank meets the technical acceptance criteria for blank analyses
or the sample meets the max_mum contamination criteria, the system
is considered to be uncontaminated. If the instrument blank or
sample does not meet the criteria (i.e., contaminated), the system
must be decontaminated. Until an instrument blank meets the blank
technical acceptance criteria or a sample meets the maximum
contamination criteria in Section 11.3.8, any samples analyzed
since the original contaminated sample will require reanalysis at
no additional cost to the Agency. NOTE: Only the instrument blank
which demonstrates that there was no carryover from the previous
sample or the instrument blank that demonstrates that the system
is clean (Section 12.1.4) needs to be reported. Instrument blanks
analyzed during the instrument decontamination process which
exceed the requirements listed in Section 12.1.4 do not need to be
reported.
12.1.3 Procedure for Blank Analyses
12.1.3.1 For water samples, a volatile method blank consists of a 5 mL
volume of reagent water (Section 7.1.1) spiked with 10 /xL of the
system monitoring compound spiking solution (Section 7.2.4.1) and
10 jiL of the internal standard spiking solution (Section 7.2.4.3)
and carried through the analytical procedure.
12.1.3.2 For low level soil/sediment samples, a volatile method blank
consists of 5 g of a purified solid matrix added to 5 mL of
reagent water that has been spiked with 10 iiL each of the system
monitoring compound spiking solution and the internal standard
spiking solution. The method blank is then carried through the
analytical procedure.
12.1.3.3 For medium level soil/sediment samples, a volatile method blank
consists of 4 g of a purified solid matrix added to 10 mL of
methanol and extracted for two minutes. A 100 /xL aliquot of the
methanol is added to reagent water and spiked with 10 /xL of the
internal standard spiking solution and 10 /xL of the system
monitoring compound spiking solution and taken through the
analytical procedure.
12.1.3.4 Storage/instrument blanks consist of a 5 mL volume of reagent
water (Section 7.1.1) spiked with 10 /uL of the system monitoring
compound spiking solution (Section 7.2.4.1) and 10 iiL of the
internal standard spiking solution (Section 7.2.4.3) and carried
through the analytical procedure.
12.1.3.5 Identify and quantitate analytes according to Section 11.0.

Blank Analyses
12.1.4 Technical Acceptance Criteria for Blank Analyses
12.1.4.1 All blanks must be analyzed on a GC/MS system meeting the BFB,
initial calibration and continuing calibration technical
acceptance criteria and at the frequency described in Section
12.1.2.
12.1.4.2 The percent recovery of each of the system monitoring compounds in
a blank must be within the acceptance windows in Table 7.
12.1.4.3 The EICP area for each of the internal standards in a blank must
be within the inclusive range of -50.0 percent and +100.0 percent
of the response of the internal standards in the most recent
continuing calibration analysis.
12.1.4.4 The retention time shift for each of the internal standards in a
blank must be within ±0.50 minutes (30 seconds) of its retention
time in the most recent continuing calibration standard analysis.
12.1.4.5 The concentration of each target compound found in the blank must
be less than its CRQL listed in Exhibit C (Volatiles), except for
methylene chloride which must be less than 2.5 times its CRQL, and
acetone and 2-butanone, which must be less than 5 times the CRQL.
12.1.5 Corrective Action for Blank Analyses
12.1.5.1 It is the Contractor's responsibility to ensure that method
interferences caused by the contaminants in solvent, reagents,
glassware, laboratory air and other sample storage and processing
hardware that lead to discrete artifacts and/or elevated baselines
in gas chromatograms be eliminated. If a Contractor's blanks
exceed the criteria in Section 12.1.4.5, the Contractor must
consider the analytical system to be out of control. The source
of the contamination must be investigated and appropriate
corrective measures must be taken and documented before further
analysis proceeds.
12.1.5.2 Any method blank or instrument blank that fails to meet the
technical acceptance criteria for blank analyses must be
reanalyzed at no additional cost to the Agency. Furthermore, all
samples, including MS/MSD samples, processed within the 12-hour
period with a method blank or instrument blank that does not meet
the technical acceptance criteria for blanks will require
reanalysis at no additional cost to the Agency.
12.1.5.3 If the storage blank does not meet the technical acceptance
criteria for blank analyses in Sections 12.1.4.1 through 12.1.4.4,
correct system problems and reanalyze the storage blank. If the
storage blank does not meet the criteria in Section 12.1.4.5,
reanalyze the storage blank to determine whether the contamination
occurred during storage or during the analysis. If, upon
reanalysis, the storage blank meets the criteria in Section
12.1.4.5, the problem occurred during the analysis and the
reanalyzed storage blank results must be reported. If upon
D-50/VOA OLM03.0
-------
Exhibit D Volatiles — Section 12
Quality Control
Matrix Spike/Matrix Spike Duplicate (MS/MSD)
reanalysis, the storage blank did not meet the criteria in Section
12.1.4.5, the problem occurred during storage. The laboratory
manager or his/her designee must address the problem in the SDG
Narrative and discuss the corrective actions implemented to
prevent future occurrences. NOTE: A copy of the storage blank
data must also be retained by the Contractor and be made available
for inspection during on-site laboratory evaluations.
12.2 Matrix Spike/Matrix Spike Duplicate (MS/MSD)
12.2.1 Summary of MS/MSD
In order to evaluate the effects of the sample matrix on the methods
used for volatile analyses, the Agency has prescribed a mixture of
volatile target compounds to be spiked into two aliquots of a sample,
and analyzed in accordance with the appropriate method.
12.2.2 Frequency of MS/MSD
12.2.2.1 A matrix spike and matrix spike duplicate must be performed for
each group of samples of a similar matrix for the following,
whichever is most frequent:
• Each SDG (not to exceed 20 field samples), or
• Each matrix within an SDG, or
• Each group of samples of a similar concentration level (soils
only).
12.2.2.2 As a part of the Agency's QA/QC program, water rinsate samples
and/or field/trip blanks (field QC) may accompany soil/sediment
samples and/or water samples that are delivered to a laboratory
for analysis. The Contractor shall not perform MS/MSD analysis on
any of the field QC samples.
12.2.2.3 If the EPA Region designates a sample to be used as an MS/MSD,
then that sample must be used. If there is insufficient sample,
less than the required amount, remaining to perform an MS/MSD,
then the Contractor shall choose another sample to perform an
MS/MSD analysis. At the time the selection is made, the
Contractor shall notify the Region (through SMO) that insufficient
sample was received and identify the EPA sample selected for the
MS/MSD analysis. The rationale for the choice of a sample other
than the one designated by the Region shall be documented in the
SDG Narrative.
12.2.2.4 If there is insufficient sample remaining in any of the samples in
an SDG to perform an MS/MSD, then the Contractor shall immediately
contact SMO to inform them of the problem. SMO will contact the
Region for instructions. The Region will either approve that no
MS/MSD is required, or require that a reduced sample aliquot be
used for the MS/MSD analysis. SMO will notify the Contractor of
D-51/VOA OLM03.0
-------
Exhibit D Volatiles — Section 12
Quality Control
Matrix Spike/Matrix Spike Duplicate (MS/MSD)
the resolution. The Contractor shall document the decision in the
SDG Narrative.
12.2.2.5 The Contractor will not be paid for MS/MSD analysis performed at a
greater frequency than required by the contract. If it appears
that the Region has requested MS/MSD analysis at a greater
frequency than required by the contract, the Contractor shall
contact SMO. SMO will contact the Region to determine which
samples should have an MS/MSD performed on them. SMO will notify
the Contractor of the Region's decision. The Contractor shall
document the decision in the SDG Narrative.
12.2.2.6 When a Contractor receives only a Performance Evaluation (PE)
sample(s), no MS/MSD shall be performed within that SDG.
12.2.2.7 When a Contractor receives a PE sample as part of a larger SDG, a
sample other than the PE sample must be chosen for the MS/MSD when
the Region did not designate samples to be used for this purpose.
If the PE sample is received as an ampulated standard extract, the
ampulated PE sample is not considered to be another matrix type.
12.2.3 Procedure for Preparing MS/MSD
12.2.3.1 Water
To prepare a matrix spike and matrix spike duplicate for water
samples, add 10 /iL of the matrix spike solution (Section 7.2.4.2)
to each of the 5 mL aliquots of the sample chosen for spiking.
Process samples according to Sections 10.1.3.7 through 10.1.3.12.
Disregarding any dilutions, this is equivalent to a concentration
of 50 ^g/L of each matrix spike compound.
12.2.3.2 Soil - Low Level
To prepare a matrix spike and matrix spike duplicate for low level
soil/sediment samples, add 10 fiL of the matrix spike solution to
the 5 mL of spiked reagent water added to each of the two aliquots
of the soil/sediment from the sample chosen for spiking. Process
samples according to Sections 10.1.4.7 through 10.1.4.12. The
concentration for a 5 g sample should be equivalent to 50 /*g/kg of
each matrix spike compound.
12.2.3.3 Soil - Medium Level
12.2.3.3.1 To prepare a matrix spike and matrix spike duplicate for medium
level soil/sediment samples, add 9 mL of methanol and 1 mL of
matrix spike solution to each of the two aliquots of the
soil/sediment sample chosen for spiking. Process samples
according to Sections 10.1.5.6 through 10.1.5.10. This results
in a 6,200 /ig/kg concentration of each matrix spike compound
when added to a 4 g sample. Add a 100 pL aliquot of this
extract to 5 mL of water for purging (as per Sections 10.1.5.8
through 10.1.5.9).

Exhibit D Volatiles — Section 12
Quality Control
Matrix Spike/Matrix Spike Duplicate (MS/MSD)
12.2.3.3.2 NOTE: Before performing an MS/MSD analysis, analyze the sample
used for MS/MSD. If the sample analysis required dilution, the
aliquots for the MS/MSD can be prepared at the same dilution as
the least diluted analysis for which the sample results will be
reported to the Agency. Sample dilutions must be performed in
accordance with Section 10.1.6. Do not further dilute MS/MSD
samples to get either spiked or non-spiked analytes within
calibration range.
12.2.4 Calculations for MS/MSD
12.2.4.1 Calculate the concentrations of the matrix spike compounds using
the same equations as used for target compounds (Equations 5, 6
and 7). Calculate the recovery of each matrix spike compound as
follows:
EQ. 12
Matrix Spike Recovery = - — x 100
Where,
SSR = Spiked sample result
SR = Sample result
S? = Spike added
12.2.4.2 Calculate the relative percent difference (RPD) of the recoveries
of each compound in the matrix spike and matrix spike duplicate as
follows:
EQ. 13
RPD = - x 100
— (MSR + MSDR)
Where,
MSR = Matrix spike recovery
MSDR = Matrix spike duplicate recovery
The vertical bars in the formula above indicate the absolute value
of the difference, hence RPD is always expressed as a positive
value.

Quality Control
Matrix Spike/Matrix Spike Duplicate (MS/MSD)
12.2.5 Technical Acceptance Criteria for MS/MSD
12.2.5.1 All MS/MSDs must be analyzed on a GC/MS system meeting the BFB,
initial calibration and continuing calibration technical
acceptance criteria, the blank technical acceptance criteria, and
at the frequency described in Section 12.2.2.
12.2.5.2 The MS/MSD must be analyzed within the contract holding time.
12.2.5.3 The retention time shift for each of the internal standards in the
MS/MSD must be within ±0.50 minutes (30 seconds) of its retention
time and the most recent continuing calibration standard analysis.
12.2.5.4 The limits for matrix spike compound recovery and RPD are given in
Table 8. As these limits are only advisory, no further action by
the laboratory is required. However, frequent failures to meet
the limits for recovery or RPD warrant investigation by the
laboratory, and may result in questions from the Agency.
12.2.6 Corrective Action for MS/MSD
Any MS/MSD that does not meet the technical acceptance criteria for
MS/MSD must be reanalyzed at no additional cost to the Agency.

14.0 POLLUTION PREVENTION
14.1 Pollution prevention encompasses any technique that reduces or
eliminates the quantity or toxicity of waste at the point of generation.
Numerous opportunities for pollution prevention exist in laboratory
operation. The EPA has established a preferred hierarchy of
environmental management techniques that places pollution prevention as
the management option of first choice. Whenever feasible, laboratory
personnel should use pollution prevention techniques to address their
waste generation. When wastes cannot be feasibly reduced at the source,
the Agency recommends recycling as the next best option.

15.0 WASTE MANAGEMENT
The Environmental Protection Agency requires that laboratory waste
management practices be conducted consistent with all applicable rules
and regulations. The Agency urges laboratories to protect the air,
water, and land by minimizing and controlling all releases from hoods
and bench operations, complying with the letter and spirit of any sewer
discharge permits and regulations, and by complying with all solid and
hazardous waste regulations, particularly the hazardous waste
identification rules and land disposal restrictions. For further
information on waste management consult The Waste Management Manual for
Laboratory Personnel, available from the American Chemical Society at

Exhibit D — Volatiles Appendix A
Screening of Hexadecane Extracts for Volatiles
APPENDIX A - SCREENING OF HEXADECANE EXTRACTS FOR VOLATILES
1.0 SCOPE AND APPLICATION
1.1 The hexadecane extraction and screening methods for purgeables described
in this section are designed to aid the analyst in deciding whether a
soil sample is low or medium level in order to prevent saturation of the
purge and trap system and/or the GC/MS system. These or other screening
methods should be used, particularly if there is some doubt about the
level of organics in a sample. This is especially true in soil/sediment
analysis. Water samples may also be screened to determine an
appropriate dilution factor for analysis.
1.2 These extractions and preparation procedures were developed for rapid
screening of water and soil/sediment samples from hazardous waste sites.
The design of the methods thus does not stress efficient recoveries or
low limits of guantitation. Rather, the procedures were designed to
screen at moderate recovery and sufficient sensitivity for a broad
spectrum of organic chemicals. The results of the analyses thus may
reflect only a minimum of the amount actually present in some samples.
This is especially true if water soluble solvents are present.
2.0 SUMMARY OF METHODS
2.1 Sample Preparation
2.1.1 Water
A 40 mL aliquot of sample is extracted with 2 mL of hexadecane. This
provides a minimum guantitation limit (MQL) as follows:
Compounds MOL (ua/D
non-halogenated aromatics 40-50
halogenated methanes 80-1000
halogenated ethanes 400-500
2.1.2 Soil/Sediment
40 mL of reagent water are added to 10 g (wet weight) of
soil/sediment and shaken. The water phase is in turn extracted with
2 mL of hexadecane. This provides a minimum quantitation limit of
approximately four times higher than those listed for water.
2.2 GC/FID Screening
The hexadecane extracts of water and soil/sediment are screened on a gas
chromatograph/flame ionization detector (GC/FID). The results of the
screen will determine if volatile organics are to be analyzed by low or
medium level GC/MS procedures if the sample is a soil/sediment, or to
determine the appropriate dilution factor if the sample is water. Note:
The flame ionization detector varies considerably in sensitivity when
comparing aromatics and halogenated methanes and ethanes. Halomethanes
are approximately 20x less sensitive than aromatics and haloethanes are
D-62/VOA OLM03.0

Exhibit D — Volatiles Appendix A
Screening of Hexadecane Extracts for Volatiles
approximately lOx less sensitive than aromatics. Low molecular weight,
water soluble solvents (e.g., alcohols and ketones, will not be
extracted from the water, and therefore will not be detected by the
GC/FID.
3.0 INTERFERENCES
Method interferences may be caused by contaminants in solvents,
reagents, glassware, and other sample processing hardware that lead to
discrete artifacts and/or elevated baselines in the total ion current
profiles. All of these materials must be routinely demonstrated to be
free from interferences under the conditions of the analysis by running
laboratory reagent blanks. Matrix interferences may be caused by
contaminants that are coextracted from the sample. The extent of matrix
interferences will vary considerably from source to source depending
upon the nature and diversity of the site being sampled.
4.0 SAFETY
The toxicity or carcinogenicity of each reagent used in this method has
not been precisely determined, however, each chemical should be treated
as a potential health hazard. Exposure to these reagents should be
reduced to the lowest possible level. The laboratory is responsible for
maintaining a current awareness file of OSHA regulations regarding the
safe handling of the chemicals specified in this method. A reference
file of data handling sheets should be made available to all personnel
involved in these analyses. Use all reagents in fume hoods whenever
possible. Always wear safety glasses or a shield for eye protection,
protective clothing and observe proper mixing when working with these
reagents.

8.0 CALIBRATION AND STANDARDIZATION
8.1 GC/FID Operating Conditions
Refer to Section 5.5.2 for recommended column temperature program.
8.2 GC Calibration
8.2.1 Summary
Prior to sample analysis each GC/FID system must be standardized for
half scale response.
8.2.2 Frequency

Exhibit D — Volatiles Appendix A
Screening of Hexadecane Extracts for Volatiles
9.1.1.2 Transfer approximately 1 tnL of the hexadecane layer to a 2 mL GC
vial. If an emulsion is present after shaking the sample, break
it by doing the following:
• Pulling the emulsion through a small plug of Pyrex glass wool
packed in a pipet, or
• Transferring the emulsion to a centrifuge tube and
centrifuging for several minutes.
9.1.2 Soil/Sediment
Add approximately 10 g of soil/sediment (wet weight) to 40 mL of
reagent water in a 50 mL centrifuge tube with a ground glass stopper
or Teflon-lined cap. Cap and shake vigorously for 1 minute.
Centrifuge the capped flask briefly. Quickly transfer supernatant
water to a 50 mL volumetric flask equipped with a ground-glass
stopper. Follow 9.1.1 starting with the addition of 2 mL of
hexadecane.
9.2 GC/FID Analysis
Inject the same volume of sample hexadecane extract as the extracted
standard mixture in 8.2.3.
9.2.1 GC/FID chromatogram Interpretation — Following are two options for
interpreting the GC/FID Chromatograms.
9.2.1.1 Option A is to use standard mixture #1 containing the aromatics to
calculate an approximate concentration of the aromatics in the
sample. Use this information to determine the proper dilution for
purge and trap if the sample is water, or whether to use the low
or medium level GC/MS purge and trap methods if the sample is
soil/sediment (see Table 1, Section 9.3 for guidance). This
should be the best approach; however, the aromatics may be absent
or obscured by higher concentrations of other purgeables. In
these cases, Option B may be the best approach.
9.2.1.2 Option B is to use standard mixture #2 containing n-nonane and n-
dodecane to calculate a factor. Use the factor to calculate a
dilution for purge and trap of a water sample or to determine
whether to use the low or medium level GC/MS purge and trap
methods for soil/sediment samples (see Table 1, Section 9.3 for
guidance). All purgeables of interest have retention times less
than the n-dodecane.
9.3 Analytical Decision Point
9.3.1 Water
9.3.1.1 Compare the chromatograms of the hexadecane extract of the sample
with those of the reagent blank and extract of the standard.
D-67/VOA OLM03.0
-------
Exhibit D — Volatiles Appendix A
Screening of Hexadecane Extracts for Volatiles
9.3.1.2 If no peaks are noted, other than those also in the reagent blank,
analyze a 5 mL water sample by purge and trap GC/MS.
9.3.1.3 If peaks are present prior to the n-dodecane and the aromatics are
distinguishable, follow Option A (Section 9.2.1).
9.3.1.4 If peaks are present prior to the n-dodecane but ths aromatics are
absent or indistinguishable, use option B as follows: if all
peaks are ^3% of the n-nonane, analyze a 5 mL water sample by
purge and trap GC/MS. If any peaks are S3%of the n-nonane,
measure the peak height or area of the major peak and calculate
the dilution factor as follows:
Peak area of sample major peak x 50 = dilution factor
Peak area of n-nonans
The water sample will be diluted using the calculated factor just
prior to purge and trap GC/MS analysis.
9.3.2 Soil/Sediment
9.3.2.1 Compare the chroraatograms of the hexadecane extract of the sample
with those of the reagent blank and extract of the standard.
9.3.2.2 If no peaks are noted, other than those also in the reagent blank,
analyze a 5 g sample by low level GC/MS.
9.3.2.3 If peaks are present prior to the n-dodecane and the aromatics are
distinguishable, follow Option A (Section 9.2.1) and the
concentration information in Table 1, to determine whether to
analyze by low or medium level method.
9.3.2.4 If peaks are present prior to the n-nonane but the aromatics are
absent or indistinguishable, and using Option B as follows,
calculate a factor using the following formula:
Peak area of sample major peak = X Factor
Peak area of n-nonane
Table 1
Determination of GC/MS Purge and Trap Method
Approximate Concentration
X Factor Analyze by Range* (^g/Kg)
0-1.0 low level method 0-1,200
> l.o medium level method >1,200
* This concentration range is based on the response of
aromatics to GC/FID. When comparing GC/FID responses, the
concentration for halomethanes is 20 times higher, and that for
haloethanes is 10 times higher.

Scope and Application
1.0 SCOPE AND APPLICATION
1.1 The analytical method that follows is designed to analyze water, soil
and sediment from hazardous waste sites for the semivolatile organic
compounds on the Target Compound List (TCL), (see Exhibit C).
1.2 The method is based on EPA Method 625 (Base/Neutrals and Acids) and it
covers the determination of a number of organic compounds that are
partitioned into an organic solvent and are amenable to gas
chromatography. These target compounds and the contract required
quantitation limits are listed in Exhibit C.
1.3 The method involves solvent extraction of the matrix sample,
characterization to determine the appropriate analytical protocol to be
used followed by appropriate cleanup procedure and GC/MS analysis to
determine the semivolatile organic compounds present in the sample.
1.4 Problems have been associated with the following compounds analyzed by
this method:
1.4.1 Dichlorobenzidine and 4-chloroaniline can be subject to oxidative
losses during solvent concentration.
1.4.2 Hexachlorocyclopentadiene is subject to thermal decomposition in the
inlet of the gas chromatograph, chemical reactions in acetone
solution, and photochemical decomposition.
1.4.3 N-nitrosodiphenylamine decomposes in the gas chromatograph inlet
forming diphenylamine and, consequently, may be detected as
diphenylamine.

Summary of Method/Definitions
2.0 SUMMARY OF METHOD
2.1 Water
A one liter aliquot of sample is acidified to pH 2.0 and extracted with
tr.ethylene chloride using a continuous liquid-liquid extractor.
Separatory funnel extraction is NOT permitted. The methylene chloride
extract is dried with sodium sulfate, concentrated, subjected to GPC
(GPC is required when higher molecular weight compounds are present that
interfere with the analyses of target compounds; GPC is optional for all
other circumstances), and analyzed by GC/MS for extractable organics.
2.2 Low Soil/Sediment
A thirty (30) gram portion of soil/sediment is mixed with anhydrous
powdered sodium sulfate and extracted with 1:1 methylene
chloride/acetone solution using an ultrasonic probe. If the low level
screen (Appendix A) is used, a portion of this dilute extract is
concentrated fivefold and screened by GC/FID or GC/MS. If peaks are
present at greater than 10,000 /xg/kg, discard the extract and prepare
the sample by the medium level method. If no peaks are present at
greater than 10,000 ^g/kg the entire extract is concentrated, subjected
to GPC cleanup, and analyzed by GC/MS for extractable organics.
2.3 Medium Soil/Sediment
Approximately one gram portion of soil/sediment is mixed with anhydrous
powdered sodium sulfate in a vial and extracted with methylene chloride.
The methylene chloride extract can be screened for extractable organics
by GC/FID or GC/MS. A method for screening is found in Appendix A. If
organic compounds are detected by the screen, the methylene chloride
extract is subjected to GPC cleanup and analyzed by GC/MS for
extractable organics. If no organic compounds are detected by the
medium level screen, then a low level sample preparation is required.
3.0 DEFINITIONS
See Exhibit G for a complete list of definitions.

Interferences/Safety
4.0 INTERFERENCES
Contaminants in solvents, reagents, glassware, and other sample
processing hardware may cause method interferences such as discrete
artifacts and/or elevated baselines in the extracted ion current
profiles (EICPs). All of these materials routinely must be demonstrated
to be free from interferences under the conditions of the analysis by
running laboratory method blanks. Matrix interferences may be caused by
contaminants that are coextracted from the sample. The extent of matrix
interferences will vary considerably from source to source.
5.0 SAFETY
The toxicity or carcinogenicity of each reagent used in this method has
not been precisely determined; however, each chemical should be treated
as a potential health hazard. Exposure to these reagents should be
reduced to the lowest possible level. The laboratory is responsible for
maintaining a current awareness file of OSHA regulations regarding the
safe handling of the chemicals specified in this method. A reference
file of data handling sheets should be made available to all personnel
involved in these analyses. Specifically, concentrated sulfuric acid
presents some hazards and is moderately toxic and extremely irritating
to skin and mucous membranes. Use these reagents in a fume hood
whenever possible and if eye or skin contact occurs flush with large
volumes of water. Always wear safety glasses or a shield for eye
protection, protective clothing, and observe proper mixing when working
with these reagents.

7.2 Standards
7.2.1 Introduction
The Contractor must provide all standards to be used with this
contract. These standards may be used only after they have been
certified according to the procedure in Exhibit E. The Contractor
must be able to verify that the standards are certified.
Manufacturer's certificates of analysis must be retained by the
Contractor and presented upon request.
7.2.2 Stock Standard Solutions
7.2.2.1 Stock standard solution may be purchased or prepared using the
following procedure.
7.2.2.1.1 Prepare stock standard solutions by accurately weighing about
0.0100 g of pure material. Dissolve the material in methylene
chloride or another suitable solvent and dilute to volume in a
10 mL volumetric flask. Larger volumes may be used at the
convenience of the analyst.
7.2.2.1.2 When compound purity is assayed to be 97.0 percent or greater,

corrected when calculating the concentration of the stock
solution. See Exhibit E (Analytical Standards Requirements).
7.2.2.1.3 Fresh stock standards must be prepared once every twelve
months, or sooner if standards have degraded or concentrated.
Stock standards must be checked for signs of degradation or
concentration just prior to preparing secondary dilution and
working standards from them.
7.2.3 Secondary Dilution Standards
7.2.3.1 Using stock standards, prepare secondary dilution standards in
methylene chloride that contain the compounds of interest either
singly or mixed together.
7.2.3.2 Fresh secondary dilution standards must be prepared once every
twelve months, or sooner if standards have degraded or
concentrated. Secondary dilution standards must be checked for
signs of degradation or concentration just prior to preparing
working standards from them.
7.2.4 Working Standards
7.2.4.1 Surrogate Standard Spiking Solution
Prepare a surrogate standard spiking solution that contains
nitrobenzenene-dS, terphenyl-d!4, 2-fluorobiphenyl, and 1,2-
dici.lorobenzene-d4 at a concentration of 100 /tg/mL; phenol-d5,
2,4,6-tribromophenol, 2-fluorophenol and 2-chlorophenol-d4 at a
concentration of 150 /xg/mL. Surrogate standards are added to all
samples and calibration solutions. Additional surrogates may be
added at the laboratory's discretion.
7.2.4.2 Matrix Spiking Solution
7.2.4.2.1 The matrix spiking solution consists of the following:
Bases/Neutrals Acids
1,2,4-Trichlorobenzene Pentachlorophenol
Acenaphthene Phenol
2,4-Dinitrotoluene 2-Chlorophenol

7.2.4.3 GPC Calibration Solution
7.2.4.3.1 Prepare a calibration solution in methylene chloride containing
the following analytes at the minimum concentrations listed (in
elution order):
Compound Concentration (mq/mL)
Corn oil 25.0
bis(2-ethylhexyl)phthalate 0.5
Methoxychlor 0.1
Perylene 0.02
Sulfur (optional) 0.08
7.2.4.3.2 NOTE: Sulfur is not very soluble in methylene chloride, but it
is soluble in warm corn oil. Therefore, one approach is to
weigh out the corn oil, warm it, and transfer the weighed
amount of sulfur into the warm corn oil. Mix it and then
transfer into a volumetric flask with methylene chloride, along
with the other calibration compounds.
7.2.4.4 Instrument Performance Check Solution.
Prepare a solution of decafluorotriphenylphosphine (DFTPP), such
that a 2 jxL injection will contain 50 ng of DFTPP. The DFTPP may
also be included in the calibration standards at this level.
7.2.4.5 Initial and Continuing Calibration Solutions.
7.2.4.5.1 Prepare calibration standards at a minimum of five
concentration levels (20, 50, 80, 120, and 160 total ng per 2
jiL). Each calibration standard should contain each compound of
interest and each surrogate. Eight compounds (2,4-
Dinitrophenol, 2,4,5-Trichlorophenol, 2-Nitroaniline, 3-
Nitroaniline, 4-Nitroaniline, 4-Nitrophenol, 4,6-Dinitro-2-
methylphenol, and Pentachlorophenol) will require only a four-
point initial calibration at 50, 80, 120, and 160 total ng per
2 /iL, since detection at less than 50 ng per injection is
difficult.
7.2.4.5.2 In order to facilitate the confirmation of single component
pesticides from the semivolatile library search data (see
Exhibit D (Pesticides/Aroclors), Section 12.1.2), the
laboratory may include the single component pesticide target
compounds listed in Exhibit C in the semivolatile continuing
calibration standard. The laboratory may add any or all of
these compounds to the semivolatile continuing calibration
standard, but at a concentration of 10 ng//*L or less. Do not
include the Aroclors or toxaphene mixtures in the semivolatile
initial and continuing calibration standards. If added to this
GC/MS standard, these additional analytes are not reported on
the semivolatile calibration form (Form VII), but must be
included in the quantitation report for the continuing

calibration standard. As only a single point calibration would
be performed, no %RSD or percent difference criteria would
apply to these additional analytes.
7.2.4.5.3 The 50 ng/2 fiL calibration standard is the continuing
calibration standard.
7.2.4.6 Internal Standard Solution.
An internal standard solution can be prepared by dissolving 100 mg
of each of the following compounds in 50 mL of methylene chloride:
l,4-dichlorobenzene-d4, naphthalene-d8, acenaphthene-dlO,
phenanthrene-dlO, chrysene-d!2 and perylene-d!2. It may be
necessary to use 5.0 to 10.0 percent toluene in this solution and
a few minutes of ultrasonic mixing in order to dissolve all the
constituents. The resulting solution will contain each standard
at a concentration of 2000 ng//iL. A 10 /±L portion of this
solution should be added to each 1 mL of sample extract just prior
to analysis by GC/MS. This will result in 40 ng of each internal
standard in the 2 ^L volume of extract injected into the GC/MS.
Note: For automated systems using an injection volume of less than
10 jtL, the internal standard solution may need to be prepared at a
different concentration. Prepare the internal standard solution
such that the aliquot used by the system maintains the required 40
ng of each internal standard in the 2 /*L volume of extract
injected into the GC/MS.
7.2.5 Ampulated Standard Extracts
Standard solutions purchased from a chemical supply house as
ampulated extracts in glass vials may be retained for 2 years from
the preparation date, unless the manufacturer recommends a shorter
time period. Standard solutions prepared by the Contractor which are
immediately ampulated in glass vials may be retained for 2 years from
the preparation date. Upon breaking the glass seal, the expiration
times listed in Sections 7.2.2.1.3, 7.2.3.2, and 7.3.3. will apply.
The Contractor is responsible for assuring that the integrity of the
standards have not degraded (see Section 7.3.5).
7.3 Storage of Standard Solutions
7.3.1 Store the stock and secondary dilution standard solutions at less
than 4 °C but not greater than 6 °C in Teflon-lined screw-cap amber
bottles. Fresh standards should be prepared every twelve months at a
minimum.
7.3.2 Store the working standards at less than 4 °C but not greater than
6 °C in Teflon-sealed containers. The solution should be checked
frequently for stability. These solutions must be replaced after
twelve months or sooner if comparison with quality control check
samples indicates a problem.

Reagents and Standards
7.3.3 The continuing calibration standard (50 ng) should be prepared weekly
and stored at less than 4 °C but not greater than 6 °C.
Refrigeration of the GPC calibration solution may cause the corn oil
to precipitate. Before use, allow the solution to stand at room
temperature until the corn oil dissolves. Replace this calibration
solution every six months, or more frequently if necessary.
7.3.4 Protect all standards from light. Samples, sample extracts and
standards must be stored separately.
7.3.5 The Contractor is responsible for maintaining the integrity of
standard solutions and verifying prior to use. Storage of standard
solutions in the freezer may cause some compounds to precipitate.
This means at a minimum, the standards must be brought to room
temperature prior to use, checked for losses, and checked that all
components have remained in solution. Additional steps may be
necessary to ensure all components are in solution.

9.2.2.2 The 12-hour time period for a GC/MS system instrument performance
check and standards calibration (initial or continuing calibration
criteria) begins at the moment of injection of the DFTPP analysis
that the laboratory submits as documentation of a compliant
instrument performance check. The time period ends after 12 hours
have elapsed according to the system clock.
9.2.3 Procedure for GC/MS Instrument Performance Check
The analysis of the instrument performance check solution may be
performed as an injection of up to 50 ng of DFTPP into the GC/MS or
by adding 50 ng of DFTPP to the calibration standards (Section
7.2.4.5) and analyzing the calibration standard.
9.2.4 Technical Acceptance Criteria for GC/MS Instrument Performance Check
9.2.4.1 The GC/MS system must be tuned at the frequency described in
Section 9.2.2.
9.2.4.2 The abundance criteria listed in Table 1 must be met for a 50 ng
injection of DFTPP. The mass spectrum of DFTPP must be acquired
in the following manner: Three scans (the peak apex scan and the
scans immediately preceding and following the apex) are acquired
and averaged. Background subtraction is required, and must be
accomplished using a single scan acquired no more than 20 scans
prior to the elution of DFTPP. Do not subtract part of the DFTPP
peak. Note: All subsequent standards, samples, MS/MSD, and
blanks associated with a DFTPP analysis must use the identical
mass spectrometer instrument conditions.

9.3.1 Summary of Initial Calibration
Prior to the analysis of samples and required blanks, and after the
instrument performance check solution criteria have been met, each
GC/MS system must be calibrated at a minimum of five concentrations
(Section 7.2.4.5) to determine instrument sensitivity and the
linearity of GC/MS response for the semivolatile target and surrogate
compounds.
9.3.2 Frequency of Initial Calibration
9.3.2.1 Each GC/MS system must be initially calibrated upon award of the
contract, whenever the contractor takes corrective action which
may change or affect the initial calibration criteria (e.g., ion
source cleaning or repairs, column replacement, etc.), or if the
continuing calibration technical acceptance criteria have not been
met.
9.3.2.2 If time still remains in the 12-hour time period after meeting the
technical acceptance criteria for the initial calibration, samples
may be analyzed. It is not necessary to analyze a continuing
calibration standard within this 12-hour time period, if the
initial calibration standard that is the same concentration as the
continuing calibration standard meets the continuing calibration
technical acceptance criteria. Quantitate all sample and quality
control sample results and quality control criteria results, such
as internal standard area response change and retention time
shift, against the initial calibration standard that is the same
concentration as the continuing calibration standard (50 ng/2 ^L).
9.3.3 Procedure for Initial Calibration
9.3.3.1 All standard/spiking solutions and blanks must be allowed to warm
to ambient temperature (approximately 1 hour) before preparation
or analysis.
9.3.3.2 Prepare five calibration standards containing all the semivolatile
target and surrogate compounds at the concentrations described in
Section 7.2.4.5.

7.2.4.6) to 1 mL aliquot of calibration standards to result in 40
ng of internal standard in the 2 fiL volume of calibration standard
injected onto the GC/MS. The internal standards specified in
Section 7.2.4.6 should permit most of the semivolatile target
compounds to have relative retention times of 0.80 to 1.20, using
the assignments of internal standards to target compounds given in

concentration levels described in Section 7.2.4.5 and at the
frequency described in Section 9.3.2 on a GC/MS system meeting the
DFTPP technical acceptance criteria.
9.3.5.2 The relative response factor (RRF) at each calibration
concentration for each semivolatile target and surrogate compound
must be greater than or equal to the compound's minimum acceptable
relative response factor listed in Table 5.
9.3.5.3 The %RSD over the initial calibration range for relative response
factor for each semivolatile and surrogate compound that has a
required %RSD must be less than or equal to the %RSD listed in
Table 5.
9.3.5.4 Up to four compounds may fail to meet the criteria listed in Table
5. However, these four compounds must meet a minimum RRF
criterion of 0.010 and have a %RSD less than or equal to 40.0
percent.
9.3.5.5 Excluding those ions in the solvent front, no quantitation ion may
saturate the detector, with the exception of quantitation ions in
up to 3 compounds (including internal standards and surrogates)
from the high standard (160 ng/2 /*L). Consu t the manufacturer's
instrument manual to determine how saturation is indicated for
your instrument.
9.3.6 Corrective Action for Initial Calibration
9.3.6.1 If any technical acceptance criteria for initial calibration are
not met, inspect the system for problems. It may be necessary to
clean the ion source, change the column, or take other corrective
actions to achieve the acceptance criteria.
9.3.6.2 Initial calibration technical acceptance criteria must be met
before any samples, including matrix spike/matrix spike duplicates
or required blanks are analyzed. Any samples, including matrix
spike/matrix spike duplicates or required blanks analyzed when
initial calibration technical acceptance criteria have not been
met will require reanalysis at no additional cost to the Agency.
9.4 Continuing Calibration
9.4.1 Summary of Continuing Calibration
Prior to the analysis of samples, including MS/MSD and required
blanks, and after tuning criteria and initial calibration criteria
have been met, each GC/MS system must be routinely checked by

contains all the semivolatile target and surrogate compounds and
internal standards.
9.4.2 Frequency of Continuing Calibration
9.4.2.1 Each GC/MS used for analysis must be calibrated once every 12-hour
time period of operation. The 12-hour time period begins with the
injection of DFTPP.
9.4.2.2 If time still remains in the 12-hour time period after meeting the
technical acceptance criteria for the initial calibration, samples
may be analyzed. It is not necessary to analyze a continuing
calibration standard within this 12-hour time period, if the
initial calibration standard that is the same concentration as the
continuing calibration standard meets the continuing calibration
technical acceptance criteria. Quantitate all sample results
against the initial calibration standard that is the same
concentration as the continuing calibration standard (50 ng/2 ;xL).
9.4.3 Procedure for Continuing Calibration

standards specified in paragraph 7.2.4.6 should permit most of the
semivolatile target compounds to have relative retention times of

9.4.5 Technical Acceptance Criteria for Continuing Calibration
9.4.5.1 The continuing calibration standard must be analyzed at the
50 ng/2 ^L concentration level at the frequency described in
Section 9.4.2, on a GC/MS system meeting the DFTPP tuning and the
initial calibration technical acceptance ciiteria.
9.4.5.2 The relative response factor (RRF) for each semivolatile target
and surrogate compound must be greater than or equal to the
compound's minimum acceptable relative response factor listed in
Table 5.
9.4.5.3 The relative response factor percent difference for each
semivolatile target and surrogate compound that has a percent
difference criteria must be within the inclusive range listed in
Table 5.
9.4.5.4 Up to four semivolatile target compounds may fail to meet the
minimum RRF or maximum percent difference criteria listed in Table
5, but the RRFs of those four compounds must be greater than or
equal to 0.010, and the percent differences must be within the
inclusive range of ±40.0 percent.
9.4.5.5 Excluding those ions in the solvent front, no quantitation ion may
saturate the detector. Consult the manufacturer's instrument
operating manual to determine how saturation is indicated for your
instrument.

9.4.6 Corrective Action for Continuing Calibration
9.4.6.1 If any continuing calibration technical acceptance criteria are
not met, recalibrate the GC/MS instrument according to Section
9.3.3. It may be necessary to clean the ion source, change the
column or take other corrective actions to achieve the continuing
calibration technical acceptance criteria.
9.4.6.2 Continuing calibration technical acceptance criteria MUST be met
before any samples, including MS/MSD or required blanks are
analyzed. Any samples, including MS/MSD or required blanks
analyzed when continuing calibration criteria have not been met
will require reanalysis at no additional cost to the Agency.

10.0 PROCEDURE
10.1 Sample Preparation
10.1.1 If insufficient sample amount (less than 90% of the required amount)
is received to perform the analyses, the Contractor shall contact SMO
to apprise them of the problem. SMO will contact the Region for
instructions. The Region will either require that no sample analyses
be performed or will require that a reduced volume be used for the
sample analysis. No other changes in the analyses will be permitted.
The Contractor shall document the Region's decision in the SDG
Narrative.
10.1.2 If multiphase samples (e.g., a two-phase liquid sample, oily
sludge/sandy soil sample) are received by the Contractor, the
Contractor shall contact SMO to apprise them of the type of sample
received. SMO will contact the Region. If all phases of the sample
are amenable to analysis, the Region may require the Contractor to do
the following:
• Mix the sample and analyze an aliquot from the homogenized
sample.
• Separate the phases of the sample and analyze each phase
separately. SMO will provide EPA sample numbers for the
additional phases.
• Separate the phases and analyze one or more of the phases, but
not all of the phases. SMO will provide EPA sample numbers for
the additional phases, if required.
• Do not analyze the sample.
10.1.2.1 If all of the phases are not amenable to analysis (i.e., .outside
scope), the Region may require the Contractor to do the following:
• Separate the phases and analyze the phase(s) that is amenable
to analysis. SMO will provide EPA sample numbers for the
additional phases, if required.
• Do not analyze the sample.
10.1.2.2 No other change in the analyses will be permitted. The Contractor
shall document the Region's decision in the SDG Narrative.
10.1.3 Water Samples
10.1.3.1 Continuous liquid-liquid extraction is used to extract the
samples. Separatory funnel extraction cannot be used.

Sample Preparation
10.1.3.2 Continuous Liquid-Liquid Extraction Without Hydrophobic Membrane
10.1.3.2.1 Follow manufacturer's instructions for set-up.
10.1.3.2.2 Add methylene chloride to the bottom of the extractor and fill
it to a depth of at least one inch above the bottom sidearm.
10.1.3.2.3 Measure out a 1 L sample aliquot in a separate, clean graduated
cylinder; transfer the aliquot to the continuous extractor.
Adjust the pH to 2.0 with 1:1 H2SC>4 and verify it with a pH
meter or narrow range pH paper. Record the pH. NOTE: With
some samples, it may be necessary to place a layer of glass
wool between the methylene chloride and the water layer in the
extractor to prevent precipitation of suspended solids into the
methylene chloride during extraction.
10.1.3.2.4 Using a syringe or volumetric pipet, add 0.5 mL of the
surrogate standard spiking solution (7.2.4.1) into the sample
and mix well.
10.1.3.2.5 Rinse the graduated cylinder with 50 mL of methylene chloride
and transfer the rinsate to the continuous extractor. If the
sample was received in a 1 L container, rinse the empty
container with 50 mL of methylene chloride and add rinsate to
the continuous extractor.
10.1.3.2.6 Add sufficient methylene chloride ;o the continuous extractor
to ensure proper solvent cycling during operation. Adjust the
drip rate to 5 to 15 mL/minute (recommended); optimize the
extraction drip rate. Extract for a minimum of 18 hours.
NOTE: When a minimum drip rate of 10-15 mLs/min is maintained
throughout the extraction, the extraction time may be reduced
to a minimum of 12 hours. Allow to cool, then detach the
distillation flask. Proceed to Section 10.2.
10.1.3.2.7 NOTE: Some continuous liquid-liquid extractors are also capable
of concentrating the extract within the extraction set-up.
Follow the manufacturer's instructions for concentration when
using this type of extractor.
10.1.3.3 Continuous Liquid-Liquid Extraction With Hydrophobic Membrane
10.1.3.3.1 Follow the manufacturer's instructions for set-up.
10.1.3.3.2 Measure out each 1 L sample aliquot in a separate, clean
graduated cylinder. If the sample was received in a 1 L
container, rinse the empty container with 50 mL of methylene
chloride and add the rinsate to the continuous extractor. If
the sample was not received in a 1 L container, add 50 mL of
methylene chloride to the continuous extractor. Slowly
transfer the aliquot to the continuous extractor. Adjust the pH
to 2.0 with 1:1 H2SO4 and verify it with a pH meter or narrow
range pH paper. Record the pH.

10.1.3.3.5 Add sufficient methylene chloride to the continuous extractor
to ensure proper solvent cycling during operation. Adjust the
drip rate to 15 mL/minute (recommended); optimize the
extraction drip rate. Extract for a minimum of 6 hours. (NOTE:
Due to the smaller volume of solvent used during the extraction
process, some sample matrices (e.g., oily samples, samples
containing a high concentration of surfactants) may create an
emulsion which will consume the solvent volume, preventing the
efficient extraction of the sample. When this occurs, add
additional solvent to assure efficient extraction of the
sample, and extend the extraction time for a minimum of 6
hours. If the sample matrix prevents the free flow of solvent
through the membrane, then the non-hydrophobic membrane
continuous liquid-liquid type extractor must be used.) Allow
to cool, then detach the distillation flask. Proceed to
Section 10.2.
10.1.3.3.6 NOTE: Some continuous liquid-liquid extractors are also capable
of concentrating the extract within the extraction set-up.
Follow the manufacturer's instructions for concentration when
using this type of extractor. Using the hydrophobic membrane
type extractor, it may not be necessary to dry the extract with
sodium sulfate.
10.1.3.4 NOTE: If low surrogate recoveries occur, assure 1) the apparatus
was properly assembled to prevent leaks; 2) the drip rate/solvent
cycling was optimized; and 3) there was proper cooling for
condensation of solvent.
10.1.3.5 NOTE: Alternate continuous liquid-liquid extractor types that meet
the requirements of the SOW may also be used. If using alternate
extractors or design types, follow the manufacturer's instructions
for set-up.
10.1.4 Soil/Sediment Samples
Decant and discard any water layer on a sediment sample. Mix samples
thoroughly, especially composited samples. Discard any foreign
objects such as sticks, leaves, and rocks.
10.1.4.1 pH Determination
Transfer 50 g of soil/sediment to a 100 mL beaker. Add 50 mL of
water and stir for 1 hour. Determine pH of sample with a pH meter
while stirring. Report pH value on appropriate data sheets. If
the pH of the soil/sediment is greater than 11 or less than 5,

sample. NOTE: If limited sample volume is received use a smaller
1:1 ratio of grams of soil/sediment sample to mLs of water for the
pH determination. Note this in the SDG Narrative.
10.1.4.2 Percent Moisture
Immediately after weighing the sample for extraction, weigh 5-10 g
of the soil/sediment into a tared crucible. Determine the percent
moisture by drying overnight at 105 °C. Allow to cool in a
desiccator before weighing. Concentrations of individual analytes
will be reported relative to the dry weight of soil/sediment.

10.1.4.3 Mandatory Determination of Concentration Level
The Contractor must determine whether a soil/sediment sample
should be analyzed by the low or medium level soil/sediment
method. It is the responsibility of the Contractor to analyze the
sample at the correct level. Three approaches may be taken to
determine whether the low level or medium 1-avel method must be
fol. jwed.
• Assume the sample is low level and analyze a 30 g sample.
• Use the screening method in Appendix A to determine the
appropriate method for analysis.
• Use an in-house laboratory screening procedure. This
procedure must be documented and available for review during
on-site laboratory evaluation or when requested by the
Technical Project Officer or Administrative Project Officer.
10.1.4.4 Low Level Soil/Sediment Samples
10.1.4,4.1 The following steps should be performed rapidly to avoid loss
of the more volatile extractables. Weigh approximately 30 g of
sample to the nearest 0.1 g into a 400 mL beaker and add 60 g
of anhydrous powdered or granulated sodium sulfate. Mix well.
The sample should have a sandy texture at this point. Add 0.5
mL of the surrogate standard spiking solution (Section 7.2.4.1)
to the sample, then immediately add 100 mL of 1:1 methylene
chloride-acetone.
10.1.4.4.2 Place the bottom surface of the tip of the 3/4 inch tapered

10.1.4.4.4 Repeat the extraction two more times with 2 additional 100 mL
portions of 1:1 methylene chloride-acetone. Before each
extraction, make certain that the sodium sulfate is free-
flowing and not a consolidated mass. As reg_uired, break up
large lumps with a clean spatula, or, very carefully, with the
tip of the unenergized probe. Decant the extraction solvent
after each sonication. On the final sonication, pour the
entire sample into the Buchner funnel and rinse with 1:1
methylene chloride-acetone.
10.1.4.4.5 ' If the sample is to be screened following the low level
preparation method prior to GPC, refer to Appendix A,
"Screening of Semivolatile Organic Extracts."
10.1.4.4.6 After screening, transfer the remainder of the 1 mL back to the
total extract. CAUTION: To minimize sample loss, autosamplers
which pre-flush samples through the syringe should not be used.
10.1.4.5 Medium Level Soil/Sediment Samples
10.1.4.5.1 Transfer approximately 1 g (record weight to the nearest 0.1 g)
of sample to a 20 mL vial. Wipe the mouth of the vial with a
tissue to remove any sample material. Record the exact weight
of sample taken. Cap the vial before proceeding with the next
sample to avoid any cross-contamination.
10.1.4.5.2 Add 2.0 g of anhydrous powdered or granulated sodium sulfate to
the sample in the 20 mL vial, and mix well.
10.1.4.5.3 Surrogates are added to all samples, spikes, and blanks. Add

Procedure
Sample Concentration
10.2 Concentrating the Extract
NOTE: Low level soil/sediment samples prepared by the procedure
described in Section 10.1.4.4 will result in extracts containing a
mixture of acetone and methylene chloride. Because all soil/sediment
sample extracts MUST be subjected to GPC cleanup prior to analysis, the
majority of the acetone must be removed from the extract, otherwise it
will have adverse effects on the GPC column. To remove the acetone from
the soil/sediment sample extract, follow the steps in Section 10.2.1
then concentrate to 1 mL using the nitrogen evaporation technique in
Section 10.2.2.2.
10.2.1 Concentration by K-D
10.2.1.1 Assemble a Kuderna-Danish (K-D) apparatus by attaching a 10 mL
concentrator tube to a 500 mL evaporative flask. Other
concentration devices or techniques may be used in place of the K-
D, if equivalency is demonstrated for all the semivolatile target
compounds listed in Exhibit C.
10.2.1.2 For water samples, transfer the extract to a Kuderna-Danish (K-D)
concentrator by pouring the extract through a drying column
containing about 10 cm of anhydrous granular sodium sulfate.
10.2.1.2.1 For soil/sediment samples, directly transfer the extract to the
K-D concentrator.
10.2.1.2.2 Rinse the Erlenmeyer flasks (for both water and soil/sediment
samples) and the column (for water samples) with 20-30 mL of
methylene chloride to complete the quantitative transfer.
10.2.1.3 Add one or two clean boiling chips to the evaporative flask and
attach a three-ball Snyder column. Pre-wet the Snyder column by
adding about 1 mL methylene chloride to the top of the column.
Place the K-D apparatus in a hot water bath (60 °C to 70 °C
recommended) so that the concentrator tube is partially immersed
in the hot water and the entire lower rounded surface of the flask
is bathed with hot vapor. Adjust the vertical position of the
apparatus and the water temperature as required to complete the
concentration in 10 to 15 minutes. At the proper rate of
distillation, the balls of the column will chatter actively, but
the chambers will not flood with condensed solvent. When the
apparent volume of liquid reaches 1 mL, remove the K-D apparatus
from the water bath and allow it to drain and cool for at Least 10
minutes. DO NOT ALLOW THE EVAPORATOR TO GO DRY. Remove the
Snyder column and rinse the flask and its lower joint into the
concentrator tube with 1 or 2 mL of methylene chloride. A 5 mL
syringe is recommended for this operation.
10.2.1.4 For water samples which do not require GPC cleanup, proceed to
final concentration of extract (Section 10.2.2). Oily water
samples require GPC.

Sample Concentration
10.2.1.5 For water samples which require GPC, adjust the volume of the
extract to 10.0 mL with methylene chloride and proceed with GPC
cleanup (Section 10.3).
10.2.1.6 For soil/sediment samples, adjust the volume of the extract to
10.0 mL with methylene chloride, and proceed with GPC cleanup
(Section 10.3).
10.2.1.7 For water samples or soil/sediment samples which have undergone
GPC, proceed to final concentration of extract (Section 10.2.2).
10.2.2 Final Concentration of Extract
Two different concentration techniques are permitted to obtain the
final extract volume: Micro Snyder column and Nitrogen Evaporation
Techniques.
10.2.2.1 Micro Snyder Column Technique
Add another one or two clean boiling chips to the concentrator
tube and attach a two-ball micro Snyder column. Pre-wet the
Snyder column by adding about 0.5 mL of methylene chloride to the
top of the column. Place the K-D apparatus on a hot water bath
(60 °C to 70 °C recommended) so that the concentrator tube is
partially immersed in the hot water. Adjust the vertical position
of the apparatus and the water temperature as required to complete
the concentration in 5 to 10 minutes. At the proper rate of
distillation, the balls of the column will chatter actively, but
the chambers will not flood with condensed solvent. When the
apparent volume of liquid reaches about 0.5 mL (0.4 mL for
soil/sediment samples or water samples that have undergone GPC),
remove the K-D apparatus from the water bath and allow it to drain
for at least 10 minutes while cooling. Remove the Snyder column
and rinse the evaporative flask and its lower joint into the
concentrator tube with 0.2 mL (0.1 mL for soil/sediment samples or
water samples that have undergone GPC) of methylene chloride.
Adjust the final volume to 1.0 mL (0.5 mL for soil/sediment
samples and water samples that have undergone GPC) with methylene
chloride. Transfer the extract to the Teflon-sealed screw-cap
bottle, label the bottle, and store at less than 4 °C but not
greater than 6 °C.
10.2.2.2 Nitrogen Evaporation Technique (Taken from ASTM Method D3086)
The following method may be used for final concentration of the
semivolatile extract instead of the procedure in Section 10.2.2.1.
Place the concentrator tube in a warm water bath (30 °C to 35 °C
recommended) and evaporate the solvent volume to just below 1 mL
(below 0.5 mL for soil/sediment samples and water samples that
have undergone GPC) by blowing a gentle stream of clean, dry
nitrogen (filtered through a column of activated carbon) above the
extract. CAUTION: Gas lines from the gas source to the
evaporation apparatus must be stainless steel, copper, or Teflon

tubing. New plastic tubing must not be used between the carbon
trap and the sample, since it may introduce interferences. The
internal wall of the concentrator tube must be rinsed down several
times with methylene chloride during the operation. During
evaporation the tube solvent level must be kept below the water
level of the bath. The extract must never be allowed to become
dry.
10.2.2.3 Final Extract Volumes
10.2.2.3.1 Water
For water samples that did not undergo GPC, the extract must be
brought to a final volume of 1.0 mL with methylene chloride.
For water samples that underwent GPC, the extract must be
brought to a final volume of 0.5 mL with methylene chloride.
(Concentrating the extract to 0.5 mL will result in no loss of
sensitivity despite the volume of extract (5 mL) not recovered
after GPC. )
10.2.2.3.2 Soil/Sediment
Adjust the final volume to 0.5 mL with methylene chloride
(concentrating the extract to 0.5 mL will result in no loss of
sensitivity despite the volume of extract (5 mL) not recovered
after GPC) .
10.2.2.3.3 Transfer the extract to a Teflon-sealed screw-cap bottle, label
the bottle, and store at less than 4 °C but not greater than 6
10.3 Sample Cleanup by GPC
10.3.1 Introduction
10.3.1.1 Gel Permeation Chromatography (GPC) is a size exclusion cleanup
procedure using organic solvents and hydrophobic gels in the
separation of natural macromolecules . The packing gel is porous
and is characterized by the range or uniformity (exclusion range)
of that pore size. In the choice of gels, the exclusion range
must be larger than the molecular size of the molecules to be
separated.
10.3.1.2 GPC must be performed for all soil/sediment extracts. GPC must be
performed for water extracts that contain higher molecular weight
contaminants that interfere with the analysis of the target
analytes.
10.3.2 GPC Column Preparation
The instructions listed below for GPC column preparation are for Bio
Beads. Alternative column packings may be used if 1) the column
packings have equivalent or better performance than the Bio Beads and

meet the technical acceptance criteria for GPC calibration and GPC
calibration check, 2) the column packings do not introduce
contaminants/artifacts into the sample which interfere with the
analysis of the semivolatile compounds. Follow the manufacturer's
instructions for preparation of the GPC column packing.
10.3.2.1 Weigh out 70 g of Bio Beads (SX-3). Transfer them to a quart
bottle with a Teflon-lined cap or a 500 mL separatory funnel with
a large bore stopcock, and add approximately 300 mL of methylene
chloride. Swirl the container to ensure the wetting of all beads.
Allow the beads to swell for a minimum of 2 hours. Maintain
enough solvent to cover the beads sufficiently at all times. If a
guard column is to be used, repeat the above with 5 g of Bio Beads
in a 125 mL bottle or a beaker using 25 mL of the methylene
chloride.
10.3.2.2 Turn the column upside down from its r.ormal position, and remove
the inlet bed support plunger (the inlet plunger is longer than
the outlet plunger). Position and tighten the outlet bed support
plunger as near the end as possible, but no closer than 5 cm
(measured from the gel packing to the collar).
10.3.2.3 Raise the end of the outlet tube to keep the solvent in the GPC
column, or close the column outlet stopcock. Place a small amount
of solvent in the column to minimize the formation of air bubbles
at the base of poured column packing.
10.3.2.4 Swirl the bead/solvent slurry to get a homogeneous mixture and, if
the wetting was done in a quart bottle, quickly transfer it to a
500 mL separatory funnel with a large bore stopcock. Drain the
excess methylene chloride directly into the waste beaker, and then
start draining the slurry into the column by placing the
separatory funnel tip against the column wall. This will help to
minimize bubble formation. Swirl occasionally to keep the slurry
homogeneous. Drain enough to fill the column. Place the tubing
from the column outlet into a waste beaker below the column, open
the stopcock (if attached), and allow the excess solvent to drain.
Raise the tube to stop the flow, and close the stopcock when the
top of the gel begins to look dry. Add additional methylene
chloride to just rewet the gel.
10.3.2.5 Wipe any remaining beads and solvent from the inner walls of the
top of the column with a laboratory tissue. Loosen the seal
slightly on the other plunger assembly (long plunger) and insert
it into the column. Make the seal just tight enough so that any
beads on the glass surface will be pushed forward, but loose
enough so that the plunger can be pushed forward.
CAUTION: Do not tighten the seal if beads are between the seal
and the glass surface because this can damage the seal and cause
leakage.

Procedure
Sample Cleanup (GPC)
10.3.2.6 Compress the column as much as possible without applying
excessive force. Loosen the seal and gradually pull out the
plunger. Rinse and wipe off the plunger. Slurry any remaining
beads and transfer them into the column. Repeat the step in
Section 10.3.2.5 and reinsert the plunger. If the plunger cannot
be inserted and pushed in without allowing beads to escape around
the seal, continue compression of the beads without tightening the
seal, and loosen and remove the plunger as described. Repeat this
procedure until the plunger is inserted successfully.
10.3.2.7 Push the plunger until it meets the gel, then compress the column
bed about four centimeters.
10.3.2.8 Pack the optional 5 cm column with approximately 5 g of pre-
swelled beads (different guard columns may require different
amounts). Connect the guard column to the inlet of the analytical
column.
10.3.2.9 Connect the column inlet to the solvent reservoir (reservoir
should be placed higher than the top of the column) and place the
column outlet tube in a waste container. Placing a restrictor in
the outlet tube will force air out of the column more quickly. A
restrictor can be made from a piece of capillary stainless steel
tubing of 1/16" OD x 0.010" ID x 2". Pump methylene chloride
through the column at a rate of 5 mL/min for one hour.
10.3.2.10 After washing the column for at least one hour, connect the column
outlet tube without the restrictor, to the inlet side of the UV
detector. Connect the system outlet to the outlet side of the UV
detector. A restrictor (same size as the one in Section 10.3.2.9)
in the outlet tube from the UV detector will prevent bubble
formation which causes a noisy UV baseline.
10.3.2.11 The restrictor will not affect flow rate. After pumping methylene
chloride through the column for an additional 1-2 hours, adjust
the inlet bed support plunger until approximately 6-10 psi
backpressure is achieved. Push the plunger in to increase
pressure or slowly pull outward to reduce pressure.
10.3.2.12 When the GPC column is not to be used for several days, connect
the column outlet line to the column inlet to prevent column
drying and/or channeling. If channeling occurs, the gel must be
removed from the column, re-swelled, and re-poured as described
above. If drying occurs, methylene chloride should be pumped
through the column until the observed column pressure is constant
and the column appears wet. Always recalibrate after column
drying has occurred to verify retention volumes have not changed.

10.3.3 Calibration of GPC
10.3.3.1 Summary of Calibration of GPC
The GPC calibration procedure is based on monitoring the elution
of standards with a UV detector connected to the GPC column.
10.3.3.2 Frequency of Calibration of GPC
Each GPC system must be initially calibrated upon award of a
contract, when the column is changed, when channeling occurs, and
once every seven days when samples, including matrix spikes and
matrix spike duplicates, and blanks are cleaned up using GPC.
10.3.3.3 Procedure for GPC Calibration
The following instructions are for the Analytical Biochemical
Laboratories system. If you are using a different GPC system,
consult your manufacturer's instruction manual for operating
instructions. A 2 mL injection loop may be used in place of a 5
mL injection loop, in accordance with the manufacturer's
instructions.
10.3.3.3.1 Verify the flow rate by collecting column eluate for 10 minutes
in a graduated cylinder and measure the volume, which should be
45-55 mL (4.5-5.5 mL/min). Once the flow rate is within the
range of 4.5-5.5 mL/min, record the column pressure (should be
6-10 psi) and room temperature. Changes in pressure, solvent
flow rate, and temperature conditions can affect analyte
retention times and must be monitored.
10.3.3.3.2 Using a 10 mL syringe, load sample loop #1 with calibration
solution (Section 7.2.4.3). With the ABC automated system, the
5 mL sample loop requires a minimum of 8 mL of the calibration
solution. Use a firm continuous pressure to push the sample
onto the loop. Switch the valve so that GPC flow is through
the UV flow-through cell.
10.3.3.3.3 Inject the calibration solution and obtain a UV trace showing a
discrete peak for each component. Adjust the detector and/or
recorder sensitivity to produce a UV trace that meets the
requirements in Section 10.3.4. Differences between
manufacturer's cell volumes and detector sensitivities may
require a dilution of the calibration solution to achieve
similar results. An analytical flow-through detector cell will
require a much less concentrated solution than the semi-prep
cell and, therefore, the analytical flow-through detector cell
is not acceptable for use.
10.3.3.3.4 Using the information from the UV trace, establish appropriate
collect and dump time periods to ensure collection of all
target analytes. Initiate column eluate collection just before
elution of bis (2-ethylhexyl) phthalate and after the elution

Procedure
Sample cleanup (GPC)
of corn oil. Stop eluate collection shortly after the elution
of perylene. Collection should be stopped before sulfur
elutes. Use a "wash" time of 10 minutes after the elution of
sulfur. Each laboratory is required to establish its specific
time sequences.
10.3.3.3.5 Reinject the calibration solution after appropriate collect and
dump cycles have been set, and the solvent flow and column
pressure have been established.
10.3.3.3.6 Measure and record the volume of collected GPC eluate in a
graduated cylinder. The volume of GPC eluate collected for
each sample extract processed may be used to indicate problems
with the system during sample processing.
10.3.3.3.7 Analyze a GPC blank by loading 5 mL of methylene chloride into
the GPC. Concentrate the methylene chloride that passes
through the system during the collect cycle using a Kuderna-
Danish (K-D) evaporator. Add internal standards at the
appropriate concentration and analyze the concentrate by GC/MS.
10.3.4 Technical Acceptance Criteria for GPC Calibration
10.3.4.1 The GPC system must be calibrated at the frequency described in
Section 10.3.3.2. The UV trace must meet the following
requirements:
• Peaks must be observed and should be symmetrical for all
compounds in the calibration solution.
• Corn oil and the phthalate peaks must exhibit > 85.0 percent
resolution.
.• The phthalate and methoxychlor peaks must exhibit > 85.0
percent resolution.
• Methoxychlor and perylene peaks must exhibit > 85.0 percent
resolution.
• Perylene and sulfur (if sulfur was added) peaks must not be
saturated and must exhibit > 90.0 percent baseline resolution.
10.3.4.2 The solvent flow rate and column pressure must be within the
ranges described in Section 10.3.3.3.1.
10.3.4.3 If the retention time shift is > 5.0 percent between calibrations,
take corrective action. Excessive retention time shifts are
caused by the following:
• Poor laboratory temperature control or system leaks.
• An unstabilized column that requires pumping methylene
chloride through it for several more hours or overnight.
D-38/SVOA OLM03.0
-------
Exhibit D Semivolatiles — Section 10
Procedure
Extract Cleanup (GPC)
• Excessive laboratory temperatures causing outgassing of the
methylene chloride.
10.3.4.4 A copy of the UV trace of the calibration solution must be
submitted with the data for the associated samples.
10.3.4.5 The analyte concentrations in the GPC blank must contain less than
the CRQL for all target compounds in Exhibit C (Semivolatiles),
except phthalate esters, which must contain less than 5 times the
CRQL.
10.3.5 Corrective Action for GPC Calibration
10.3.5.1 If the requirements in Section 10.3.4 cannot be met, the column
may be cleaned by processing several 5 mL volumes of butylchloride
through the system. Butylchloride removes the discoloration and
particles that may have precipitated out of the methylene chloride
extracts. If a guard column is being used, replace it with a new
one. This may correct the problem. If column maintenance does
not restore the performance of the column, the column must be
repacked with new packing and recalibrated. It may be necessary
to obtain a new lot of Bio Beads if the column fails all criteria.
10.3.5.2 If the GPC blank exceeds the requirements in 10.3.4.5, pump
additional methylene chloride through the system for 1-2 hours.
Analyze another GPC blank to ensure the system is sufficiently
clean. Repeat the methylene chloride pumping if necessary.
10.4 Sample Extract Cleanup by GPC
10.4.1 It is very important to have constant laboratory temperatures during
an entire GPC run, which could be 24 hours or more. If temperatures
are not constant, retention times will shift, and the dump and
collect times determined by the calibration standard no longer will
be appropriate. The ideal laboratory temperature to prevent
outgassing of the methylene chloride is 22 °C.
10.4.2 In order to prevent overloading of the GPC column, highly viscous
sample extracts must be diluted prior to cleanup. Any sample extract
with a viscosity greater than that of a 1:1 glycerol:water solution
must be diluted and loaded into several loops. Similarly, extracts
containing more than 40 mg/mL of nonvolatile residue must be diluted
and loaded into several loops. The nonvolatile residue may be
determined by evaporating a 100 jiL aliquot of the extract to dryness
in a tared aluminum weighing pan, or other suitable container.
Systems using automated injection devices to load the sample on the
column must be carefully monitored to assure that the required amount
is being injected on the column. Viscous extracts or extracts
containing a large amount of non-volatile residue will cause problems
with an automated injection system's ability to inject the proper
amount of sample extract on a column. After the sample extract has
been processed, the remaining sample extract in the injection vial
must be checked before proceeding with extract cleanup to assure that
D-39/SVOA OLM03.0
-------
Exhibit D Semivolatiles — Section 10
Procedure
Extract Cleanup (GPC)
the proper amount was injected on the column. If the proper amount
of extract was not injected, the sample must be re-prepared at no
additional cost to the Agency, and the sample extract must either be
diluted and loaded into several loops or the sample extract must be
injected manually.
Note: When multiple loops/runs are necessary for an individual
sample, be sure to combine the all of the sample eluates collected
from each run.
10.4.3 Frequency of GPC Sample Cleanup
GPC cleanup must be performed once for each soil/sediment extract and
for water extracts that contain high molecular weight contaminants
that interfere with the analysis of the target analytes. In
addition, GPC must be performed for all associated blanks, matrix
spikes and matrix spike duplicates. If Cleanup procedure is
inadequate, contact SMO.
10.4.4 Procedure for GPC Sample Cleanup
10.4.4.1 Particles greater than 5 microns may scratch the valve, which may
result in a system leak and cross contamination of sample extracts
in the sample loops. To avoid such problems, filter the extract
through a 5 micron filter disc by attaching a syringe filter
assembly containing the filter disc to a 10 mL syringe. Draw the
sample extract through the filter assembly and into the 10 /zL
syringe. Disconnect the filter assembly before transferring the
sample extract into a small glass container, e.g., a 15 mL culture
tube with a Teflon-lined screw cap. Alternatively draw the
extract into the syringe without the filter assembly. Attach the
filter assembly and force the extract through the filter and into
the glass container. Draw a minimum of 8 mL of extract into a 10
mL syringe.
Note: Some GPC instrument manufacturer's recommend using a
smaller micron size filter. Follow the manufacturer's recommended
operating instructions.
10.4.4.2 Introduction of particulates or glass wool into the GPC switching
valves may require factory repair of the apparatus.
10.4.4.3 The following instructions are for the Analytical Biochemical
Laboratories system. If a different GPC system is being used,
consult the manufacturer's instruction manual for operating
instructions. A 2 mL injection loop may be used in place of a
5 mL injection loop. If a 2 mL injection loop is used,
concentrate the sample extract to 4 mL instead of 10 mL and then
inject 2 mL instead of 5 mL.
10.4.4.4 Attach the syringe to the turn lock on the injection port. Use
firm, continuous pressure to push the sample onto the 5 mL sample
loop. If the sample is difficult to load, some part of the system

Exhibit D Semivolatiles — Section 10
Procedure
Final Concentration/Sample Analysis by GC/MS
may be blocked. Take appropriate corrective action. If the back
pressure is normal (6-10 psi) the blockage is probably in the
valve. Blockage may be flushed out of the valve by reversing the
inlet and outlet tubes and pumping solvent through the tubes (this
should be done before sample loading).
10.4.4.5 Approximately 2 mL of extract remains in the lines between the
injection port and the sample loop; excess sample also passes
through the sample loop to waste. (ABC system)
10.4.4.6 After loading a loop, and before removing the syringe from the
injection port, index the GPC to the next loop. This will prevent
loss of sample caused by unequal pressure in the loops. After
loading each sample loop, wash the loading port with methylene
chloride in a PTFE wash bottle to minimize cross-contamination.
Inject approximately 10 mL of methylene chloride to rinse the
common tubes.
10.4.4.7 After loading all the sample loops, index the GPC to 00 position,
switch to the "RUN" mode and start the automated sequence.
Process each sample using the collect and dump cycle time
established in Section 10.3.3.3.3.
10.4.4.8 Collect each sample in a 250 mL Erlenmeyer flask, covered with
aluminum foil to reduce solvent evaporation, or directly into a
Kuderna-Danish (K-D) evaporator. Monitor r. ample volumes
col ected. Changes in sample volumes collected may indicate one
or more of the following problems:
• Change in solvent flow rate, caused by channeling in the
column or changes in column pressure.
• Increase in column operating pressure due to the absorption of
particles or gel fines onto either the guard column or the
analytical column gel, if a guard column is not used.
• Leaks in the system or significant variances in room
temperature.
10.5 Final Concentration
Concentrate the extract as per Section 10.2.2. Final volumes should be
brought to the volumes stated in Section 10.2.2.3.
10.6 Sample Analysis by GC/MS
10.6.1 Sample extracts shall be analyzed only after the GC/MS system has met
the instrument performance check, initial calibration, and continuing
calibration requirements. The same instrument conditions must be
employed for the analysis of samples as were used for calibration.
10.6.2 Internal standard solution is added to each sample extract. Add 10
/xL of internal standard solution to each accurately measured 1.0 mL
D-41/SVOA OLM03.0
-------
Exhibit D Semivolatiles — Section 10
Procedure
Sample Analysis by GC/MS
of water sample extract. For soil/sediment samples and water samples
subjected to GPC, add 5 fiL of internal standard solution to each
accurately measured 0.5 mL of sample extract. This will result in a
concentration of 20 ng//*L of each internal standard.
Note: An alternate amount of internal standard solution may be
added, however, the internal standards must be added to maintain the
required 20 ng//*L of each internal standard in the sample extract.
10.6.3 Prior to the addition of internal standards, make any extract
dilution indicated by characterization step. Add internal standards
after dilution. Internal standards must be added to maintain the
required 20 ng/>L of each internal standard in the extract volume.
10.6.4 Inject 2 /tL of the sample extract into the GC/MS. This 2 /*L volume
must contain 40 ng of each internal standard.
10.6.5 Sample Dilutions
10.6.5.1 If the on-column concentration of any compound in any sample
exceeds the initial calibration range, that sample extract must be
diluted, the internal standard concentration must be readjusted,
and the sample extract must be reanalyzed. Guidance in performing
dilution and exceptions to this requirement are given below.
10.6.5.2 Use the results of the original analysis to determine the
approximate dilution factor required to get the largest analyte
peak within the initial calibration range.
10.6.5.3 The dilution factor chosen should keep the response of the largest
peak for a target compound in the upper half of the calibration
range of the instrument.
10.6.5.4 Do not submit data for more than two analyses, i.e., the original
sample extract and one dilution, or if the semivolatile screening
procedure was employed, from the most concentrated dilution
analyzed and one further dilution.

Data Analysis and Calculations
Qualitative Identification
11.0 DATA ANALYSIS AND CALCULATIONS
11.1 Qualitative Identification
11.1.1 Identification of Target Compounds
11.1.1.1 The compounds listed in the Target Compound List (TCL), Exhibit C
(Semivolatile), shall be identified by an analyst competent in the
interpretation of mass spectra (see Exhibit A, Section 4.3.1) by
comparison of the sample mass spectrum to the mass spectrum of the
standard of the suspected compound. Two criteria must be
satisfied to verify the identifications.
• Elution of the sample analyte within GC relative retention
time unit window established from the 12-hour calibration
standard.
• Correspondence of the sample analyte and calibration standard
component mass spectra.
11.1.1.2 For establishing correspondence of the GC relative retention time
(RRT), the sample component RRT must compare within ±0.06 RRT
units of the RRT of the standard component. For samples analyzed
during the same 12-hour time period as the initial calibration
standards, compare the analyte retention times to those from the
50 ng calibration standard. For reference, the standard must be
run on the same shift as the sample. If co-elution of interfering
components prohibits accurate assignment of the sample component
RRT from the total ion chromatogram, the RRT should be assigned by
using extracted ion current profiles for ions unique to the
component of interest.
11.1.1.3 For comparison of standard and sample component mass spectra, mass
spectra obtained from a calibration standard on the Contractor's
GC/MS meeting the daily instrument performance requirements for
DFTPP are required. Once obtained, these standard spectra may be
used for identification purposes, only if the contractor's GC/MS
meets the DFTPP daily instrument performance requirements.
11.1.1.4 The requirement for qualitative verification by comparison of mass
spectra are as follows:
• All ions present in the standard mass spectrum at a relative
intensity greater than 10.0 percent (most abundant ion in the
spectrum equals 100.0 percent) must be present in the sample
spectrum.
• The relative intensities of ions specified in the paragraph
above must agree within ±20.0 percent between the standard
and sample spectrum. (Example: For an ion with an abundance
of 50.0 percent in the standard spectrum, the corresponding
sample ion abundance must be between 30.0 and 70.0 percent).
D-43/SVOA OLM03.0
-------
Exhibit D Semivolatiles — Section 11
Data Analysis and Calculations
Qualitative Identification
• Ions greater than 10.0 percent in the sample spectrum but not
present in the standard spectrum must be considered and
accounted for by the analyst making the comparison. In Task
II (Exhibit A) the verification process should favor false
positives. All compounds meeting the identification criteria
must be reported with their spectra. When target compounds
are below contract required guantitation limits (CRQL) but the
spectrum meets the identification criteria, report the
concentration with a "J". For example, if the CRQL is 10 /tg/L
and concentration of 3 /ig/L is calculated, report as "3J".
11.1.1.5 If a compound cannot be verified by all of the criteria in Section
11.1.1 (11.1.1.1 through 11.1.1.4), but in the technical judgement
of the mass spectra interpretation specialist the identification
is correct, then the contractor shall report the identification
and proceed with guantitation.
11.1.2 Identification of Non-Target Compounds
11.1.2.1 A library search shall be executed for non-target sample
components for the purpose of tentative identification. For this
purpose, the NIST/EPA/NIH (May 1992 release cr later) and/or Wiley
(1991 release or later), or equivalent mass spectral library shall
be used.
11.1.2.2 Up to 30 organic compounds of greatest apparent concentration not
listed in Exhibit C for the volatile and semivolatile fraction,
excluding the surrogate and internal standard compounds, shall be
identified tentatively via a forward search of the NIST/EPA/NIH
(May 1992 release or later) and/or Wiley (1991 release or later),
or equivalent mass spectral library. The following are not to be
reported; 1) Substances with responses less than 10 percent of the
internal standard (as determined by inspection of the peak areas
or heights); 2) substances which elute earlier than 30 seconds
before the first semivolatile compound listed in Exhibit C
(Semivolatiles) or three minutes after the last semivolatile
compound listed in Exhibit C has eluted; and 3) volatile compounds
listed in Exhibit C. Only after visual comparison of sample
spectra to spectra resulting from the library search(es) will the
mass spectral interpretation specialist assign a tentative
identification. NOTE: Computer generated library search routines
must not use normalization routines that would misrepresent the
library or unknown spectra when compared to each other.
11.1.2.3 Peaks that are suspected to be straight-chain, branched, or cyclic
alkanes, alone or part of an alkane series shall be library
searched. Documentation for the tentative identification must be
supplied. Alkanes are not counted as part of the 30 organic
compounds described in section 11.1.2.2.
11.1.2.4 Peaks that are suspected to be aldol-condensation reaction
products (i.e., 4-methyl-4-hydroxy-2-pentanone and 4-methyl-3-
pentene-2-one) shall be searched and reported and counted as part

Qualitative Identification
of the 30 most intense non-target semivolatile compounds and are
qualified with an "A" flag on Form I TIC.
11.1.2.5 Guidelines for Making Tentative Identifications
11.1.2.5.1 Major ions in the reference spectrum (ions greater than 10
percent of the most abundant ion) should be present in the
sample spectrum.
11.1.2.5.2 The relative intensities of the major ions should agree within
± 20 percent (Example: For an ion with an abundance of 50
percent in the standard spectrum, the corresponding sample ion
abundance must be between 30 and 70 percent).
11.1.2.5.3 Molecular ions present in reference spectrum should be present
in sample spectrum.
11.1.2.5.4 Ions present in the sample spectrum but not in the reference
spectrum should be reviewed for possible background
contamination or presence of co-eluting compounds.
11.1.2.5.5 Ions present in the reference spectrum but not in the sample
spectrum should be reviewed for possible subtraction from the
sample spectrum because of background contamination or co-
eluting compounds. NOTE: Data system library reduction
programs sometimes can create these disciepancies.
11.1.2.5.6 If, in the technical judgement of the mass spectral
interpretation specialist, no valid tentative identification
can be made, the compound should be reported as unknown. The
mass spectral interpretation specialist should give additional
classification of the unknown compound, if possible (i.e.,
unknown phthalate, unknown hydrocarbon, unknown acid type,
unknown chlorinated compound). If probable molecular weights
can be distinguished, include them.
11.1.2.5.7 The Contractor shall report pesticide target compounds listed
in Exhibit C (Pesticides) that appear as semivolatile
tentatively identified compounds.
11.1.2.5.8 Straight-chain, branched, or cyclic alkanes are NOT to be
reported as tentatively identifed compounds on FORM IF (FORM I
SV-TIC). When the above alkanes are tentatively identifed, the
concentration(s) are to be estimated as described in Section
11.2.2 and reported in the SPG narrative as alkanes, by class
(i.e. straight-chain, branched, or cyclic; as a series; as
applicable).

11.2 Calculations
11.2.1 Target Compounds
11.2.1.1 Target compounds identified rhall be quantitated by the internal
standard method. The internal standard used shall be the one
assigned to that analyte for guantitation (see Table 2). The EICP
area of primary characteristic ions of analytes listed in Tables 3
and 4 are used for guantitation.
11.2.1.2 It is expected that situations will arise where the automated
guantitation procedures in the GC/MS software provide
inappropriate quantitations. This normally occurs when there is
compound co-elution, baseline noise, or matrix interferences. In
these circumstances, the Contractor must perform a manual
guantitation. Manual quantitations are performed by integrating
the area of the quantitation ion of tne compound. This
integration shall only include the area attributable to the
specific TCL compound. The area integrated shall not include
baseline background noise. The area integrated shall not extend
past the point where the sides of the peak intersect with the
baseline noise. Manual integration is not to be used solely to
meet QC criteria, nor is it to be used as a substitute for
corrective action on the chromatographic system. Any instance of
manual integration must be documented in the SDG Narrative.
11.2.1.3 In all instances where the data system report has been edited, or
where manual integration or quantitation has been performed, the
GC/MS operator must identify such edits or manual procedures by
initialing and dating the changes made to the report, and shall
include the integration scan range. In addition, a hardcopy
printout of the EICP of the quantitation ion displaying the manual
integration shall be included in the raw data. This applies to
all compounds listed in Exhibit C (Semivolatiles), internal
standards and surrogates.
11.2.1.4 The requirements listed in 11.2.1.2 and 11.2.1.3 apply to all
standards, samples including MS/MSD, and blanks.
11.2.1.5 The relative response factor (RRF) from the continuing calibration
analysis is used to calculate the concentration in the sample.
For samples analyzed during the same 12-hour time period as the
initial calibration standards, use the RRF values from the 50 ng
calibration standard. Secondary ion quantitation is allowed ONLY
when there are sample interferences with the primary ion. If
secondary ion quantitation is performed, document the reason in
the SDG Narrative. The area of a secondary ion cannot be used for
the area of a primary ion unless a relative response factor is
calculated using the secondary ion.
11.2.1.6 Calculate the concentration in the sample using the relative
response factor (RRF) and the following equations.

Technical Acceptance Criteria For Sample Analysis
11.3 Technical Acceptance Criteria for Sample Analysis
11.3.1 The samples must be analyzed on a GC/MS system meeting the DFTPP,
initial calibration, continuing calibration, and blank technical
acceptance criteria. The sample must undergo cleanup procedures,
when required, on a GPC meeting the technical acceptance criteria for
GPC calibration.
11.3.2 The sample must be extracted and analyzed within the contract holding
times.
11.3.3 The sample must have an associated method blank meeting the blank

additional cost to the Agency.
11.4.2 Corrective Action for Surrogate Recoveries Which Fail to Meet Their
Acceptance Criteria (Section 11.3.4, Table 7)
11.4.2.1 If the surrogate compounds fail to meet their recovery acceptance
criteria, check calculations, sample preparation logs, the
surrogate compound spiking solutions, and the instrument
operation. If the calculations were incorrect, correct the
calculations and verify that the surrogate compound recoveries
meet their acceptance criteria. If the sample preparation logs
indicate that the incorrect amount of surrogate compound spiking
solution was added, then re-extract/reanalyze the sample after
adding the correct amount of surrogate spiking solution. If the
surrogate compound spiking solution was improperly prepared,
concentrated, or degraded, re-prepare solutions and re-
extract/reanalyze samples. If the surrogate recoveries were
outside the lower surrogate acceptance limit and the extract from
the sample was cleaned up on a GPC using an automated injection
system, the Contractor shall verify that the proper amount was
injected on the GPC column. If insufficient sample volume was
injected on the GPC, the sample must be reprepared and reanalyzed
at no additional cost to the Agency. If the instrument
malfunctioned, correct the instrument problem and reanalyze the
sample extract. Verify that the surrogate recoveries meet their
acceptance criteria. If the instrument malfunction affected the
calibrations, recalibrate the instrument before reanalyzing the
sample extract.
11.4.2.2 If the above actions do not correct the problem, then the problem
may be due to a sample matrix effect. To determine if there was
matrix effect, take the following corrective action steps.
11.4.2.2.1 Re-extract and reanalyze the sample. EXCEPTION: If surrogate
compound recoveries in a sample used for a matrix spike and/or
matrix spike duplicate were considered unacceptable, then it
should be re-extracted/reanalyzed only if surrogate compound
recoveries met the surrogate acceptance criteria in both the
matrix spike and matrix spike duplicate analysis.
11.4.2.2.2 If the surrogate compound recoveries meet acceptance criteria
in the re-extracted/reanalyzed sample, then the problem was
within the Contractor's control. Therefore, submit only data
from the re-extraction/reanalysis.
11.4.2.2.3 If the surrogate compound recoveries fail to meet the
acceptance criteria in the re-extracted/reanalyzed sample, then
submit data from both analyses. Distinguish between the
initial analysis and the re-extraction/reanalysis on all
deliverables, using the suffixes in Exhibit B.

11.4.3.1 If the internal standards fail to meet their acceptance criteria,
check calculations, the internal standard compound spiking
solutions, and the instrument operation. If the calculations were
incorrect, correct the calculations and verify that the internal
standard response met their acceptance criteria. If the internal
standard compound spiking solution was improperly prepared,
concentrated, or degraded, re-prepare solutions and re-
extract/reanalyze samples. If the instrument malfunctioned,
correct the instrument problem and reanalyze the sample extract.
If the instrument malfunction affected the calibration,
recalibrate the instrument before reanalyzing the sample extract.
11.4.3.2 If the above actions do not correct the problem, then the problem
may be due to a sample matrix effect. To determine if there was
matrix effect, take the following corrective action steps.
11.4.3.2.1 Reanalyze the sample extract. EXCEPTION: If internal standard
compound recoveries in a sample used for a matrix spike and/or
matrix spike duplicate were outside t.he acceptance windows,
then it should be reanalyzed only if internal standard compound
recoveries met the surrogate acceptance criteria in both the
matrix spike and matrix spike duplicate analysis.
11.4.3.2.2 If the internal standard compound recoveries meet acceptance
criteria in the reanalyzed sample extract, then the problem was
within the Contractor's control. Therefore, submit only data
from the reanalysis.
11.4.3.2.3 If the internal standard compound recoveries fail to meet their
acceptance windows in the reanalyzed sample extract, then
submit data from both analyses. Distinguish between the
initial analysis and the reanalysis on all deliverables, using

11.4.4 Corrective Action for Surrogate Compounds Relative Retention
Times/Internal Standard Compound Retention Times Outside Acceptance
Criteria (Sections 11.3.5 and 11.3.6)
11.4.4.1 If the surrogate compounds relative retention times or internal
standard compounds retention times are not within their acceptance
criteria, check the instrument for malfunctions. If the
instrument malfunctioned, correct the instrument problem and
reanalyze the sample extract. If the instrument malfunction
affected the calibration, recalibrate the instrument before
reanalyzing the sample extract.
11.4.4.2 If the above actions do not correct the problem, then the problem
may be due to a sample "matrix effect". To determine if there was
matrix effect, take the following corrective action steps.

12.0 QUALITY CONTROL
12.1 Method Blanks
12.1.1 Summary of Method Blanks
A method blank is a volume of a clean reference matrix (reagent water
for water samples, or purified sodium sulfate for soil/sediment
samples) that is carried through the entire analytical procedure.
The volume or weight of the reference matrix must be approximately
equal to the volume or weight of samples associated with the blank.
The purpose of a method blank is to determine the levels of
contamination associated with the processing and analysis of samples.
12.1.2 Frequency of Method Blanks
Method blank extraction and analysis must be performed once for the
following, whichever is most frequent, and analyzed on each GC/MS
system used to analyze associated samples:
• Each SDG, or
• Each 20 samples in an SDG, including matrix spikes/matrix spike
duplicates, that are of a similar matrix (water, soil/sediment)
or similar concentration (soil/sediment only), or
• Whe lever samples are extracted by tne same procedure (continuous
liquid-liquid extraction or sonication).
12.1.3 Procedure for Method Blank Preparation
For semivolatile analyses, a method blank for water samples consists
of 1 L volume of reagent water spiked with 0.5 mL of the surrogate
spiking solution. For medium and low level soil/sediment samples, a
method blank consists of 1 g and 30 g of sodium sulfate spiked with
0.5 mL of the surrogate spiking solution respectively. Extract,
concentrate, cleanup and analyze the blank according to procedures
for water and soil samples.
12.1.4 Technical Acceptance Criteria for Method Blank Analysis
12.1.4.1 All blanks must be extracted and analyzed at the frequency
described in Section 12.1.2 on a GC/MS system meeting the DFTPP,
initial calibration, and continuing calibration technical
acceptance criteria.
12.1.4.2 The blank must meet the sample acceptance criteria listed in
Sections 11.3.4 through 11.3.7.
12.1.4.3 For all other target compounds, the method blank must contain less
than the CRQL of any single target compound (see Exhibit C). A
method blank for semivolatile analysis must contain less than five

times (5x) the contract required guantitation limit (CRQL) of the
phthalate esters listed in Exhibit C.
12.1.5 Corrective Action for Method Blanks
12.1.5.1 If a method blank does not meet the technical acceptance criteria
for method blank analysis, the Contractor shall consider the
analytical system to be out of control.
12.1.5.2 If contamination is the problem, then the source of the
contamination must be investigated and appropriate corrective
measures must be taken and documented before further sample
analysis proceeds. It is the Contractor's responsibility to
ensure that method interferences caused by contaminants in
solvent, reagents, glassware, and sample storage and processing
hardware that lead to discrete artifacts and/or elevated baselines
in the GC/MS be eliminated. Samples associated with the
contaminated blank must be re-extracted and reanalyzed at no
additional cost to the Agency.
12.1.5.3 If surrogate recoveries in the method blank do not meet the
acceptance criteria listed in 11.3.4 and Table 7, first reanalyze
the method blank. If tho surrogate recoveries (except those with
advisory limits) do not meet the acceptance criteria after
reanalysis, the method blank and all samples associated with that
method blank must be re-extracted and reanalyzed at no additional
cost to the Agency.
12.1.5.4 If the method blank does not meet internal standard response
requirements listed in 11.3.6, check calculations, the internal
standard spiking solutions, and the instrument operation. If the
calculations were incorrect, correct the calculations and verify
that the internal standard responses meet their acceptance
criteria. If the internal standard compound spiking solution was
improperly prepared, concentrated, or degraded, re-prepare
solutions and re-extract/reanalyze samples. If the instrument
malfunctioned, correct the instrument problem and reanalyze the
method blank. If the instrument malfunction affected the
calibration, recalibrate the instrument before reanalyzing the
blank. The Contractor shall resolve and document the resolution
of the problem before proceeding with sample analysis.
12.1.5.5 If the method blank does not meet the retention time requirements
for internal standards (11.3.7) or the surrogate (11.3.5), check
the instrument for malfunction, and recalibrate. Reanalyze the
method blank. Sample analyses cannot proceed until the method
blank meets these requirements.

MS/MSD
12.2 Matrix Spike/Matrix Spike Duplicate (MS/MSD)
12.2.1 Summary of MS/MSD
In order to evaluate the effects of the sample matrix on the methods
used for semivolatile analyses, the Agency has prescribed a mixture
of semivolatile target compounds to be spiked into two aliquots of a
sample and analyzed in accordance with the appropriate method.
12.2.2 Frequency of MS/MSD Analyses
12.2.2.1 A matrix spike and matrix spike duplicate must be extracted and
analyzed for every 20 field samples of a similar matrix in an SDG,
whenever samples are extracted by the same procedure.
12.2.2.2 As part of the Agency's QA/QC program, water rinsate samples
and/or field/trip blanks (field QC) may accompany soil/sediment
samples and/or water samples that are delivered to the laboratory
for analysis. The Contractor shall not perform MS/MSD analysis on
any of the field QC samples.
12.2.2.3 If the EPA Region designates a sample to be used as an MS/MSD,
then that sample must be used. If there is insufficient sample
remaining to perform an MS/MSD, then the Contractor shall choose
another sample on which to perform an MS/MSD analysis. At the
time the selection is made, the Contractor shall notify the Region
(through SMO) that insufficient sample was received and identify
the EPA sample selected for the MS/MSD analysis. The rationale
for the choice of another sample other than the one designated by
the Agency shall be documented in the SDG Narrative.
12.2.2.4 If there is insufficient sample remaining in any of the samples in
an SDG to perform an MS/MSD, then the Contractor shall immediately
contact SMO to inform them of the problem. SMO will contact the
Region for instructions. The Region will either approve that no
MS/MSD is required, or require that a reduced sample aliquot be
used for the MS/MSD analysis. SMO will notify the Contractor of
the Region's decision. The Contractor shall document the decision
in the SDG Narrative.
12.2.2.5 The Contractor will not be paid for MS/MSD analysis performed at
greater frequency than is required by the contract. If it appears
that the Region has requested MS/MSD analysis at a greater
frequency than required by the contract, then the Contractor shall
contact SMO. SMO will contact the Region to determine which
samples should have an MS/MSD performed on them. SMO will notify
the Contractor of the Region's decision. The Contractor shall
document the decision in the SDG Narrative.
12.2.2.6 When a Contractor receives only a performance evaluation (PE)
sample(s), no MS/MSD shall be performed within that SDG.

Quality Control
MS/MSD
12.2.2.7 When a Contractor receives a performance evaluation (PE) sample as
part of a larger SDG, a sample other than the PE sample must be
chosen for the MS/MSD when the Region did not designate samples to
be used for this purpose. If the PE sample is an ampulated
standard, the ampulated PE sample is not considered to be another
matrix type.
12.2.3 Procedure for Preparing MS/MSD
12.2.3.1 Water Samples
For water samples, prepare two additional 1 L aliquots of the
sample chosen for spiking in two continuous extractors. Add 0.5
mL of surrogate spiking solution and 0.5 mL of the matrix spiking
solution to each aliquot. Extract, concentrate, cleanup, and
analyze the MS/MSD according to the procedures for water samples.
12.2.3.2 Soil/Sediment Samples - Low Level
For low level soil/sediment samples, prepare two additional 30 g
aliquots (record weight to nearest 0.1 g) of the sample chosen for
spiking in the two 400 mL beakers. Add 60 g of anhydrous powdered
sodium sulfate to each aliqout. Mix well. Add 0.5 mL of the
surrogate standard spiking solution and 0.5 mL of the matrix
spiking solution to each aliquot, then immediately add 100 mL of
1:1 methylene chloride-acetone. Extract, concentrate, cleanup,
and analyze the MS/MSD according to the procedures for low level
soil samples.
12.2.3.3 Soil/Sediment Samples - Medium Level
For medium level soil/sediment samples, prepare two additional 1 g
aliquots (record weight to nearest 0.1 g) of the sample chosen for
spiking in two 20 mL vials. Add 2.0 g of anhydrous powdered
sodium sulfate to each aliquot. Mix well. Add 0.5 mL of
surrogate spiking solution, 0.5 mL of matrix spiking solution, and
9.0 mL of methylene chloride. Extract, concentrate, cleanup, and
analyze the MS/MSD according to the procedures for medium level
samples.
12.2.4 Dilution of MS/MSD
Before any MS/MSD analysis, analyze the original sample, then analyze
the MS/MSD at the same concentration as the most concentrated extract
for which the original sample results will be reported. For example,
if the original sample is to be reported at a 1:1 dilution and a 1:10
dilution, then analyze and report the MS/MSD at a 1:1 dilution only.
However, if the original sample is to be reported at a 1:10 dilution
and a 1:100 dilution, then the MS/MSD must be analyzed and reported
at a 1:10 dilution only. Do not further dilute the MS/MSD samples to
get either spiked or non-spiked analytes within calibration range.

MS/MSD
Dilution of the sample must be performed in accordance to the
conditions in Section 10.6.5.
12.2.5 Calculations for MS/MSD
12.2.5.1 Calculate the recovery of each matrix spike compound in the matrix
spike and matrix spike duplicate and report on the appropriate
forms. Calculate the concentrations of the matrix spike compounds
using the same equations as used for target compounds (Equations 6
and 7). Calculate the recovery of each matrix spike compound as
follows:
EQ. 11
Matrix Spike Recovery = - — x 100
Where,
SSR = Spike Sample Result
SR = Sample Result
SA = Spike Added
12.2.5.2 Calculate the relative percent difference (RPD) of the recoveries
of each compound in the matrix spike and matrix spike duplicate as
follows:
EQ. 12
RPD = \MSR ~ MSDR\ x 100
(MSR + MSDR}
Where,
RPD = Relative Percent Difference
MSR = Matrix Spike Recovery
MSDR = Matrix Spike Duplicate Recovery
The vertical bars in the formula above indicate the absolute value
of the difference, hence RPD is always expressed as a positive
value.

12.2.6 Technical Acceptance Criteria for MS/MSD
12.2.6.1 All MS/MSD must be prepared and analyzed at a frequency described
in Section 12.2.2. All MS/MSD must be analyzed on a GC/MS system
meeting DFTPP, initial and continuing calibration technical
acceptance criteria and the method blank technical acceptance
criteria. The MS/MSD must undergo cleanup procedures, when
required, on a GPC meeting the technical acceptance criteria for
GPC calibration.
12.2.6.2 The MS/MSD must have an associated method blank meeting the blank
technical acceptance criteria.
12.2.6.3 The MS/MSD must be extracted and analyzed within the contract
holding time.
12.2.6.4 The retention time shift for each of .he internal standards must
be within ±0.50 minutes (30 seconds) between the MS/MSD sample and
the most recent continuing calibration standard.
12.2.6.5 The relative retention time for the surrogate must be within
±0.06 RRT units of its standard retention time in the continuing
calibration standard.
12.2.6.6 The limits for matrix spike compound recovery and RPD are given in
Table 6. As these limits are only advisory, no further action by
the laboratory is required, however, frequent failures to meet the
limits for recovery or RPD warrant investigation by the
laboratory, and may result in questions from the Agency.
12.2.7 Corrective Action for MS/MSD
Any MS/MSD which fails to meet the technical acceptance criteria for
MS/MSD must be reanalyzed at no additional cost to the Agency.

14.0 POLLUTION PREVENTION
14.1 Pollution prevention encompasses any technique that reduces or
eliminates the quantity or toxicity of waste at the point of generation.
Numerous opportunities for pollution prevention exist in laboratory
operation. The EPA has established a preferred hierarchy of
environmental management techniques that places pollution prevention as
the management option of first choice. Whenever feasible, laboratory
personnel should use pollution prevention techniques to address their
waste generation. When wastes cannot be feasibly reduced at the source,
the Agency recommends recycling as the next best option.

15.0 WASTE MANAGEMENT
The Environmental Protection Agency requires that laboratory waste
management practices be conducted consistently with all applicable rules
and regulations. The Agency urges laboratories to protect the air,
water, and land by minimizing and controlling all releases from hoods
and bench operations, complying with the letter and spirit of any sewer
discharge permits and regulations, and by complying with all solid and
hazardous waste regulations, particularly the hazardous waste
identification rules and land disposal restrictions. Fcr further
information on waste management consult The Waste Management Manual for
Laboratory Personnel, available from the American Chemical Society at

Screening of Semivolatile Organic Extracts
APPENDIX A - SCREENING OF SEMIVOLATILE ORGANIC EXTRACTS
1.0 SCOPE AND APPLICATION
1.1 The analytical method described in this section is designed to
characterize soil/sediment samples from hazardous waste sites for the
concentration level of organics.
1.2 The method involves the preparation of soil/sediment samples which may
contain organic compounds at a level greater than 10,000 jtg/kg and
screening with a gas chromatograph equipped with a flame ionization
detector (GC/FID).
1.3 For soil/sediment samples, the results of the screen are used to
determine which of the two sample preparation procedures (low or medium)
is required, and to determine appropriate dilution factor for GC/MS
analysis. The results of the screen may also be used to assist the
analyst in performing Gel Permeation Chromatography (GPC) cleanup
procedures on extracts of either water or soil/sediment samples.
1.4 The procedure is designed to allow a g_uantitation limit for screening
purposes as low as 10,000 /ug/kg for extractable organics. For analysis
purposes, the quantitation limit is 10,000 ^g/kg for extractable
organics. Some samples may contain high concentrations of compounds
that interfere with the analysis of other components at lower levels;
the guantitation limits in those cases may be significantly higher.
1.5 These ext iction and preparation procedures were developed for rapid and
safe handling of high concentration hazardous waste samples. The design
of the methods thus does not stress efficient recoveries or low limits
of quantitation of all components. Rather, the procedures were designed
to screen, at moderate recovery and sufficient sensitivity, a broad
spectrum of organic chemicals. The results of the analyses thus may
reflect only a minimum of the amount actually present in some samples.
2.0 SUMMARY OF METHOD
2.1 It is mandatory that all soil/sediment samples be characterized as to
concentration level so that the appropriate analytical protocol is
chosen to ensure proper quantitation limits for the sample. Note that
the terms "low level" and "medium level" are descriptions of the
concentration ranges that are encompassed by the "low" and "medium"
level procedures.
2.2 The laboratory is at liberty to select the method of characterization.
The following two screening methods may be used for soil/sediment
sample characterization:
• Screen an aliquot from the "low level" 30 g extract or an aliquot
from the "medium level" 1 g extract.
• Screen using GC/FID as the screening instrument.
D-70/SVOA OLM03.0
-------
Exhibit D Semivolatiles — Appendix A
Screening of Semivolatile Organic Extracts
2.3 The concentration ranges covered by these two procedures may be
considered to be approximately 330 /*g/kg - 10,000 /*g/kg for the low
level analysis and >10,000 /xg/kg for medium level analysis for
semivolatile extractables.
2.4 Sample Preparation
2.4.1 Low Level Soil/Sediment
A 30 g portion of soil/sediment is mixed with anhydrous powdered
sodium sulfate and extracted with 1:1 methylene chloride/acetone
using an ultrasonic probe.
5.0 mL of the 300 mL (approximate) total extract is concentrated to
1.0 mL and screened. If the original sample concentration is >10,000
/xg/Kg, the 30 g extract is discarded and the medium level preparation
procedure followed.
2.4.2 Medium Level Soil/Sediment
Approximately 1 g portions of soil/sediment are transferred to vials,
mixed with anhydrous powdered sodium sulfate and extracted with
methylene chloride. 5.0 mL of the 10.0 mL extract is concentrated to
1.0 mL and screened. If the sample concentration is <10,000 ^tg/kg
the 1 g extract is discarded and the low level method is followed.
2.5 GC/FID Screening
The concentrated extracts of soil/sediment or water samples are screened
on a gas chromatograph/flame ionization detector using a fused silica
capillary column (FSCC) for semivolatile priority pollutants and related
organics. The results of these screens will determine whether
sufficient quantities of pollutants are present to warrant analysis by
the medium level protocol.
3.0 INTERFERENCES
Method interferences may oe caused by contaminants in solvents,
reagents, glassware, and other sample processing hardware that lead to
discrete artifacts and/or elevated baselines in the chromatograms. All
of these materials routinely must be demonstrated to be frae from
interferences under the conditions of the analysis by running laboratory
method blanks. Matrix interferences may be caused by contaminants that
are co-extracted from the sample. The extent of matrix interferences
will vary considerably from source to source.
4.0 SAFETY
4.1 The toxicity or carcinogenicity of each reagent used in this method has
not been precisely determined; however, each chemical should be treated
as a potential health hazard. Exposure to these reagents should be
reduced to the lowest possible level. The laboratory is responsible for
maintaining a current awareness file of OSHA regulations regarding the
safe handling of the chemicals specified in this method. A reference
file of data handling sheets should be made available to all personnel

involved in these analyses. Specifically, concentrated sulfuric acid
presents some hazards and is moderately toxic and extremely irritating
to the skin and mucous membranes. Use these reagents in fume hoods
whenever possible, and if eye or skin contact occurs, flush with large
volumes of water.
4.2 Always wear safety glasses or a shield for eye protection, protective
clothing and observe proper mixing when working with these reagents.

9.3.1 Soil/Sediment
9.3.1.1 If no sample peaks from the extract (from low or medium level
preparation) are detected, or all are less than 10.0 percent full
scale deflection, the sample must be prepared by the low level
protocol.
9.3.1.2 Peaks are detected at greater than 10.0 percent full scale
deflection and less than or equal to full scale deflection.
• If the screen is from the medium level extract, proceed with
GC/MS analysis of this extract with appropriate dilution if
necessary.
• If the screen is from the low level extract, discard the
extract and prepare the samples by medium level method for
GC/MS analysis.
9.3.1.3 Peaks are detected at greater than full scale deflection.
• If the screen is from the medium level preparation, calculate
the dilution necessary to reduce the major peaks to between
half and full scale deflection. Use this dilution factor to
dilute the extract. This dilution is analyzed by GC/MS for
extractable organics.
• If the screen is from the low level preparation, discard the
extract and prepare the samples by the medium level method for
GC/MS analysis.

Scope and Application
1.0 SCOPE AND APPLICATION
1.1 The analytical method that follows is designed to analyze water,
sediment and soil from hazardous waste sites to determine the presence
and concentration of the chlorinated pesticides and Aroclors found in
the Target Compound List (TCL) in Exhibit C. The method can be used for
determining analyte concentrations in the range from the contract
required quantitation limits (CRQL) to one million times the CRQL in
these matrices when appropriate dilutions are made. The method is based
on EPA Method 608, and it covers sample extraction, extract cleanup
techniques and GC/EC analytical methods for pesticides and Aroclors.
1.2 Resolution difficulties have been associated with the following pairs of
compounds using this method:
• On a DB-608 or equivalent column, DDE and dieldrin; methoxychlor and
endrin ketone; and endosulfan I and gamma-Chlordane.
• On a DB-1701 or equivalent column, endosulfan I and gamma-Chlordane,
and methoxychlor and endosulfan sulfate.
1.3 There are two isomers of heptachlor epoxide, the endo isomer (isomer A)
and the exo isomer (isomer B). The two isomers are separable using
current GC capillary columns. Only the exo isomer (isomer B) is of
environmental significance. This is the isomer that must be used as an
analytical standard, identified and quantitated in sample analysis, and
reported on appropriate forms as heptachlor epoxide.

Summary of Method/Definitions
2.0 SUMMARY OF METHOD
2.1 Water
Continuous liquid-liquid or separatory funnel extraction procedures are
employed for aqueous samples. AIL volume of sample is spiked with the
surrogate solution and extracted with methylene chloride using a
separatory funnel or a continuous extractor. The methylene chloride
extract is dried with anhydrous sodium sulfate, concentrated and cleaned
up by GPC (GPC is required when higher molecular weight compounds are
present that interfere with the analyses of target compounds; GPC is
optional for all other circumstances). The extract is then solvent-
exchanged into hexane, cleaned up by Florisil cartridges, and the final
volume adjusted to 1 mL or 2 mL. The extract is analyzed using a dual
column wide-bore capillary Gas Chromatography/Electron Capture (GC/EC)
technique.
2.2 Soil/Sediment
A 30 g aliquot of sample is spiked with the surrogate and then mixed
with anhydrous sodium sulfate and extracted with a 1:1 acetone/methylene
chloride solvent mixture by sonication. The extract is filtered,
concentrated and solvent-exchanged into methylene chloride. The
methylene chloride extract is then cleaned up by GPC (mandatory),
solvent-exchanged into hexane, cleaned up by Florisil cartridge, and
adjusted to a final volume of 1 mL or 2 mL. The extract is analyzed
using a dual column wide-bore capillary Gas Chromatography/Electron
Capture (GC/EC) technique.
3.0 DEFINITIONS
See Exhibit G for a complete list of definitions.
D-5/PEST OLM03.0

Exhibit D Pesticides/Aroclors — Sections 4 & 5
Interferences/Safety
4.0 INTERFERENCES
4.1 Method interferences may be caused by contaminants in solvents,
reagents, glassware, and other sample processing hardware. These
contaminants lead to discrete artifacts or to elevated baselines in gas
chromatograms. Routinely, all of these materials must be demonstrated
to be free from interferences under the conditions of the analysis by
running reagent blanks. Interferences caused by phthalate esters can
pose a major problem in pesticide analysis. Common flexible plastics
contain varying amounts of phthalates which are easily extracted during
laboratory operations, so cross-contamination of glassware frequently
occurs when plastics are handled. Interferences from phthalates can
best be minimized by avoiding the use of such plastics in the
laboratory.
4.2 Matrix interferences may be caused by contaminants that are co-extracted
from the sample. The extent of matrix interferences will vary
considerably from source to source, depending upon the nature of the
site being sampled. The cleanup procedures must be used to remove such
interferences in order to achieve the contract required quantitation
limits.
5.0 SAFETY
5.1 The toxicity or carcinogenicity of each reagent used in this method has
not been precisely determined; however, each chemical should be treated
as a potential health hazard. Exposure to these rtagents should be
reduced to the lowest possible level. The laboratory is responsible for
maintaining a current awareness file of OSHA regulations regarding the
safe handling of the chemicals specified in this method. A reference
file of data handling sheets should be made available to all personnel
involved in these analyses. Specifically, concentrated sulfuric acid
and the 10 N sodium hydroxide solution are moderately toxic and
extremely irritating to skin and mucous membranes. Use these reagents
in a fume hood whenever possible and if eye or skin contact occurs,
flush with large volumes of water. Always wear safety glasses or a
shield for eye protection, protective clothing, and observe proper
mixing when working with these reagents.
5.2 The following analytes covered by this method have been tentatively
classified as known or suspected human or mammalian carcinogens: 4,4'-
DDT, 4,4'-DDD, the BHCs, and the Aroclors. Primary standards of these
toxic compounds should be prepared in a hood. A NIOSH/MESA approved
toxic gas respirator should be worn when the analyst handles high
concentrations of these toxic compounds.

that maintains a constant column flow rate throughout temperature
program operations. The system must be suitable for splitless
injection and have all required accessories including syringes,
analytical columns and gases.
6.23.2 Gas chromatographs that are available from some manufacturers may
have difficulty in meeting certain method QC requirements because of
endrin and DDT breakdown in the injector. This problem can be
minimized by operating the injector at 200 - 205 °C, using a Pvrex
(not quartz) methyl silicone deactivated injector liner, and
deactivating the metal parts in the injector with dichlorodimethyl
silane. In some cases, using a 0.25 inch packed column injector
converted for use with 0.53 mm capillary columns works better than a
Grob-type injector. If a Grob-type injector is used, a 4 mm liner
may be required to meet breakdown criteria.

9.2.4 Calculations for Initial Calibration
9.2.4.1 During the initial calibration sequence, absolute retention times
(RT) are determined for all single component pesticides, the
surrogates, and at least three major peaks of each multicomponent
analyte.
9.2.4.2 For single component pesticides, an RT is measured in each of
three calibration standards and the mean RT is calculated as the
average of the three values. An RT is measured for the surrogates

in each of the three analyses of Individual Standard Mixture A

RT =

Where,
ET = Mean absolute retention time of analyte.
RTj = Absolute retention time of analyte.
n = Number of measurements (3).
9.2.4.3 A retention time window is calculated for each single component
analyte and surrogate and for the major peaks (3 to 5) of each
multicomponent analyte by using the list in Table 1. Windows are
centered around the mean absolute retentior time for the analyte
est olished during the initial calibrations. Analytes are
identified when peaks are observed in the RT window for the
compound on both GC columns.
9.2.4.4 The linearity of the instrument is determined by calculating a
percent relative standard deviation (%RSD) of the calibration
factors from a three-point calibration curve for each single
component pesticide and surrogate. Either peak area or peak
height may be used to calculate calibration factors used in the
%RSD equation. For example, it is permitted to calculate
linearity for endrin based on peak area and to calculate linearity
for aldrin based on peak height. It is not permitted within a
%RSD calculation for an analyte to use calibration factors
calculated from both peak area and peak height. For example, it
is not permitted to calculate the calibration factor for the low
point standard for endrin using peak height and calculate the
midpoint and high point standard calibration factors for endrin
using peak area.
9.2.4.5 Calculate the calibration factor for each single component
pesticide and surrogate over the initial calibration range using

may exceed the 20.0 percent limit for %RSD (25.0 percent for
alpha-BHC and delta-BHC), but those compounds must have a %RSD of
less than or equal to 30.0 percent.
9.2.5.8 The resolution between any two adjacent peaks in the midpoint
concentrations of Individual Standard Mixtures A and B in the
initial calibration must be greater than or equal to 90.0 percent.
9.2.5.9 All instrument blanks must meet the technical acceptance criteria
in Section 12.1.4.4.
9.2.5.10 The identification of single component pesticides by gas
chromatographic method^ is based primarily on retention time data.
The retention time of the apex of a peak can only be verified from
an on-scale chromatogram. The identification of muIticomponent
analytes by gas chromatographic methods is based primarily on
recognition of patterns of retention times displayed on a
chromatogram. Therefore, the following requirements apply to all
data presented for single component and multicomponent analytes.
• The chromatograms that result from the analyses of the
Resolution Check Mixture, the PEM, and Individual Standard
Mixtures A and B during the initial calibration sequence must
display the single component analytes present in each standard
at greater than 10 percent of full scale but less than 100
percent of full scale.
• The chromatograms for at least one of the three analyses each
of Individual Standard Mixtures A and B from the initial
calibration sequence must display the single component

analytes at greater than 50 percent and less than 100 percent
of full scale.
• The chromatograms of the standards for the multicomponent
analytes analyzed during the initial calibration sequence must
display the peaks chosen for identification of each analyte at
greater than 25 percent and less than 100 percent of full
scale.
• For any standard containing alpha-BHC, the baseline of the
chromatogram must return to below 50 percent of full scale
before the elution time of alpha-BHC, and return to below 25
percent of full scale after the elution time of alpha-BHC and
before the elution time of decachlorobiphenyl.

9.3 Calibration Verification
9.3.1 Summary of Calibration Verification
Three types of analyses are used to verify the calibration and
evaluate instrument performance. The analyses of instrument blanks,
PEMs, and the midpoint concentration of Individual Standard Mixtures
A and B constitute the continuing calibration. Sample data are not
acceptable unless bracketed by acceptable analyses of instrument
blanks, PEMs, and both Individual Standard Mixtures A and B.
9.3.2 Frequency of Calibration Verification
9.3.2.1 An instrument blank and the PEM must bracket one end of a 12-hour
period during which sample data are collected, and a second
instrument blank and the midpoint concentration of Individual
Standard Mixtures A and B must bracket the other end of the 12-
hour period.
9.3.2.2 For the 12-hour period immediately following the initial
calibration sequence, the instrument blank and the PEM that are
the last two steps in the initial calibration sequence bracket the
front end of that 12-hour period. The injection of the instrument
blank starts the beginning of that 12-hour period (see Section
10.2.2.1). Samples may be injected for 12 hours from the
injection of the instrument blank. The three injections
immediately after that 12-hour period must be an instrument blank,
Individual Standard Mixture A, and Individual Standard Mixture B.
The instrument blank must be analyzed first, before either
standard. The Individual Standard Mixtures may be analyzed in
either order (A,B or B,A).
9.3.2.3 The analyses of the instrument blank and Individual Standard
Mixtures A and B immediately following one 12-hour period may be
used to begin the subsequent 12-hour period, provided that they
meet the acceptance criteria in Section 9.3.5. In th?°t instance,
the subsequent 12-hour period must be bracketed by the acceptable
analyses of an instrument blank and a PEM, in that order. Those
two analyses may in turn be used to bracket the front end of yet
another 12-hour period. This progression may continue every 12
hours until such time as any of the instrument blanks, PEMs, or
Individual Standard Mixtures fails to meet the acceptance criteria
in Sections 9.3.5. The 12-hour time period begins with the
injection of the instrument blank.
9.3.2.3.1 Standards (PEM or Individual Standard Mixtures), samples and
required blanks may be injected for 12 hours from the time of
injection of the instrument blank.

Exhibit D Pesticides/Aroclors — Section 9
Calibration and Standardization
Calibration Verification
9.3.2.4 If more than 12 hours have elapsed since the injection of the
instrument blank that bracketed a previous 12-hour period, an
acceptable instrument blank and PEM must be analyzed in order to
start a new sequence. This requirement applies even if no
analyses were performed since that standard was injected.
9.3.2.5 The requirements for running the instrument blanks, PEM, and
Individual Standard Mixtures A and B are waived when no samples,
dilutions, reanalyses, method/sulfur blanks, MS/MSD, and
multicomponent analytes for the 72-hour confirmation requirement
are analyzed during that 12-hour period. To resume analysis,
using the existing initial calibration, the Contractor first must
analyze an instrument blank and PEM which meet the technical
acceptance criteria.
9.3.2.6 If the entire 12-hour period is not required for the analyses of
all samples to be reported, the sequence must be ended with either
the instrument blank/PEM combination or the instrument
blank/Individual Standard Mixtures A and B combination, whichever
was due to be performed at the end of the 12-hour period.
9.3.3 Procedure for Calibration Verification
9.3.3.1 Analyze the PEM, instrument blank and the midpoint concentration
of Individual Standard Mixtures A and B at the required
frequencies (Section 9.3.2).
9.3.3.2 All standards and blanks must be at ambient temperature at the
time of preparation and analysis.
9.3.4 Calculations for Calibration Verification
9.3.4.1 For each analysis of the PEM used to demonstrate continuing
calibration, calculate the percent difference between the amount
of each analyte (including the surrogates) found in the PEM and
the nominal amount using Equations 5 and 9.
9.3.4.2 Calculate the percent breakdown of DDT and endrin, and the
combined breakdown in each PEM analyzed using Equations 5, 6, 7,
and 8.
9.3.4.3 For each analysis of the midpoint concentration of Individual
Standard Mixtures A and B used to demonstrate continuing
calibration, calculate the percent difference between the amount
of each analyte (including the surrogates) found in the standard
mixture and the nominal amount using Equations 5 and 9. Do not
attempt to calculate the breakdown of Endrin and DDT in the
Individual Standard Mixtures, as these standards contain the
breakdown products as well as the parent compounds.

9.3.5 Technical Acceptance Criteria for Calibration Verification
All calibration verification technical acceptance criteria apply
independently to each column. Each column roust meet criteria.
9.3.5.1 The PEMs, Individual Standard Mixtures A and B and instrument
blanks must be analyzed at the required frequency on a GC/EC
system that has met the initial calibration technical acceptance
criteria.
9.3.5.2 All single component pesticides and surrogates in the PEMs used to
demonstrate continuing calibration must be greater than or equal
to 90.0 percent resolved. The resolution between any two adjacent
peaks in the midpoint concentrations of Individual Standard
Mixtures A and B in the initial calibration must be greater than
or equal to 90.0 percent.
9.3.5.3 The absolute retention time for each of the single component
pesticides and surrogates in the PEMs and midpoint concentration
of the Individual Standard Mixtures used to demonstrate continuing
calibration must be within the retention time window determined
from the three-point initial calibration in Section 9.2.4.3.
9.3.5.4 The percent difference between the calculated amount and the
nominal amount (amount added) for each of the single component
pesticides and surrogates in the PEM must be greater than or equal
to -25.0 percent and less than or equal to 25.0 percent.
9.3.5.5 The percent difference between the calculated amount and the
nominal amount (amount added) for each of the single component
pesticides and surrogates in the INDA and INDB that have been used
as calibration verification must be greater than or equal to -25.0
percent and less than or equal to 25.0 percent.
9.3.5.6 The percent breakdown of DDT in the PEM must be less than or equal
to 20.0 percent on e^ch column. The percent breakdown of endrin
in the PEM must be less than or equal to 20.0 percent on each
column. The combined breakdown of both DDT and endrin must be
less than or equal to 30.0 percent on each column.
9.3.5.7 All instrument blanks must meet the technical acceptance criteria
in Section 12.1.4.4.
9.3.5.8 The identification of single component pesticides by gas
chromatographic methods is based primarily on retention time data.
Since the retention time of the apex of a. peak can only be
verified from an on-scale chromatogram, the following requirements
must be met for continuing calibration to be acceptable.
9.3.5.8.1 The chromatograms that result from the analyses of the PEM and
the Individual Standard Mixtures must display the single
component analytes present in each standard at greater than 10
percent of full scale but less than 100 percent of full scale.
D-32/PEST OLM3.0
-------
Exhibit D Pesticides/Aroclors — Section 9
Calibration and Standardization
Calibration Verification
9.3.5.8.2 For any PEM, Individual Standard Mixture or blank, the baseline
of the chromatogram must return to below 50 percent of full
scale before the elution time of alpha-BHC, and return to below
25 percent of full scale after the elution time of alpha-BHC
and before the elution time of deca-chlorobiphenyl.
9.3.5.8.3 If a chromatogram is replotted electronically to meet these
requirements, the scaling factor used must be displayed on the
chromatogram.
9.3.5.8.4 If the chromatogram of any standard or blank needs to be
replotted electronically to meet these requirements, both the
initial chromatogram and the replotted chromatogram(s) must be
submitted in the data package.
9.3.6 Corrective Action for Calibration Verification
9.3.6.1 If the technical acceptance criteria for the calibration
verification are not met, inspect the system for problems and take
corrective action to achieve the acceptance criteria.
9.3.6.2 Major corrective actions such as replacing the GC column or baking
out the detector will require that a new initial calibration be
performed that meets the technical acceptance criteria in Section
9.2.5.
9.3.6.3 Minor corrective actions may not require performing a new initial
calibration, provided that a new analysis of the standard (PEM or
Individual Standard Mixture) that originally failed the criteria
and an associated instrument blank immediately after the
corrective action do meet all the acceptance criteria.
9.3.6.4 If a PEM or Individual Standard Mixture does not meet technical
acceptance criteria listed above, it must be reinjected
immediately. If the second injection of the PEM or Individual
Standard Mixture meets the criteria, sample analysis may continue.
If the second injection does not meet the criteria, all data
collection must be stopped. Appropriate corrective action must be
taken, and a new initial calibration sequence must be run before
more sample data are collected.
9.3.6.5 If an instrument blank does not meet the technical acceptance
criteria listed in Section 12.1.4.4, all data collection must be
stopped. Appropriate corrective action must be taken to clean out
the system, and an acceptable instrument blank must be analyzed
before more sample data are collected.
9.3.6.6 Analysts are reminded that running an instrument blank and a PEM
or Individual Standard Mixtures once every 12 hours is the minimum
contract requirement. Late eluting peaks may carry over from one
injection to the next if highly complex samples are analyzed or if
the GC conditions are unstable. Such carryover is unacceptable.
D-33/PEST OLM3.0
-------
Exhibit D Pesticides/Aroclors — Section 9
Calibration and Standardization
Calibration Verification
Therefore, it may be necessary to run instrument blanks and
standards more often to avoid discarding data.
9.3.6.7 If a successful instrument blank and PEM cannot be run after an
interruption in analysis (Section 9.3.2.5), an acceptable initial
calibration must be run before sample data may be collected. All
acceptable sample analyses must be preceded and followed by
acceptable standards and instrument blanks, as described in
Section 9.3.2.
9.3.6.8 Calibration verification technical acceptance criteria must be met
before any samples, including MS/MSD and required blanks are
reported. Any samples, including KS/MSD and required blanks
associated with a calibration verification which did not meet the
technical acceptance criteria will require reanalysis at no
additional cost to the Agency.

10.0 PROCEDURE
10.1 Sample Preparation
10.1.1 If insufficient sample amount (less than 90% of the required amount)
is received to perform the analyses, the Contractor shall contact SMO
to apprise them of the problem. SMO will contact the Region for
instructions. The Region will either require that no sample analyses
be performed or will require that a reduced volume be used for the
sample analysis. No other changes in the analyses will be permitted.
The Contractor shall document the Region's decision in the SDG
Narrative.
10.1.2 If multiphase samples (e.g., a two-phase liquid sample, oily
sludge/sandy soil sample) are received by the Contractor, the
Contractor shall contact SMO to apprise them of the type of sample
received. SMO will contact the Region. If all phases of the sample
are amenable to analysis, the Region may require the Contractor to do
the following:
• Mix the sample and analyze an aliquot from the homogenized
sample.
• Separate the phases of the sample and analyze each phase
separately. SMO will provide EPA sample numbers for the
additional phases.
• Separate the phases and analyze one or more of the phases, but
not all of the phases. SMO will provide EPA sample numbers for
the additional phases, if required.
• Do not analyze the sample.
10.1.2.1 If all of the phases are not amenable to analysis (i.e., outside
scope), the Region may require the Contractor to do the following:
• Separate the phases and analyze the phase(s) that is amenable
to analysis. SMO will provide EPA sample numbers for the
additional phases, if required.
• Do not analyze the sample.
10.1.2.2 No other change in the analyses will be permitted. The Contractor
shall document the Region's decision in the SDG Narrative.
10.1.3 Extraction of Water Samples
Water samples may be extracted by either a separatory funnel
procedure or a continuous liquid-liquid extraction procedure. If an
emulsion prevents acceptable solvent recovery with the separatory
funnel procedure, continuous liquid-liquid extraction must be
employed.

Sample Preparation
10.1.3.1 Separatory Funnel Extraction
10.1.3.1.1 Measure out each 1 L sample aliquot in a separate graduated
cylinder. Measure and record pH of the sample with wide range
pH paper and adjust the pH to between 5 and 9 with 10 N sodium
hydroxide or concentrated sulfuric acid, if required. Samples
requiring pH adjustment must be noted in the SDG Narrative.
Place the sample into a 2 L separatory funnel.
10.1.3.1.2 Using a syringe or a volumetric pipet, add 1.0 mL of the
surrogate solution to all water samples.
10.1.3.1.3 Rinse the graduated cylinder with 30 mL of methylene chloride
and transfer the rinsate to the separatory funnel. If the
sample was received in a 1 L container, rinse the empty
container with 30 mL of methylene chloride and add rinsate to
the separatory funnel. If the sample container is not rinsed,
then add another 30 mL of methylene chloride to the separatory
funnel and extract the sample by shaking the funnel for two
minutes, with periodic venting to release excess pressure.
NOTE: The total volume of solvent used for extraction is 60 mL.
Allow the organic layer to separate from the water phase for a
minimum of 10 minutes. If the emulsion interface between
layers is more than one-third the volume of the solvent layer,
the analyst must employ mechanical techniques to complete the
phase separation. The optimum technique depends upon the
sample, and may include stirring, filtration of the emulsion
through glass wool, centrifugation or other physical means.
Drain the methylene chloride into a 250 mL Erlenmeyer flask.
10.1.3.1.4 Add a second 60 mL volume of methylene chloride to the
separatory funnel and repeat the extraction procedure a second
time, combining the extracts in the Erlenmeyer flask. Perform
a third extraction in the same manner.
10.1.3.2 Continuous Liquid-Liquid Extraction
10.1.3.2.1 Continuous Liquid-Liquid Extraction Without Hydrophobic
Membrane
10.1.3.2.1.1 Follow manufacturer's instructions for set-up.
10.1.3.2.1.2 Add methylene chloride to the bottom of the extractor and
fill it to a depth of at least one inch above the bottom
sidearm.
10.1.3.2.1.3 Measure out each 1 L sample aliquot in a separate, clean
graduated cylinder; transfer the aliquot to the continuous
extractor. Measure the pH of the sample with wide range pH
paper and record pH. Adjust the pH to between 5 and 9 with
10 N sodium hydroxide or concentrated sulfuric acid, as
required. Samples requiring the pH adjustment must be noted
in the SDG Narrative. NOTE: With some samples, it may be

methylene chloride and the water layer in the extractor to
prevent precipitation of suspended solids into the methylene
chloride during extraction.
10.1.3.2.1.4 Using a syringe or volumetric pipet, add 1.0 mL of the
surrogate standard spiking solution (7.2.4.1) into the
sample and mix well.
10.1.3.2.1.5 Rinse the graduated cylinder with 50 mL of methylene
chloride and transfer the rinsate to the continuous
extractor. If the sample was received in a 1 L container,
rinse the empty container with 50 mL of methylene chloride
and add the rinsate to the continuous extractor.
10.1.3.2.1.6 Add sufficient methylene chloride to the continuous
extractor to ensure proper solvent cycling during operation.
Adjust the drip rate to 5 to 15 mL/minute (recommended);
optimize the extraction drip rate. Extract for a minimum of
18 hours. NOTE: When a minimum drip rate of 10-15
mLs/minute is maintained throughout the extraction, the
extraction time may be reduced to a minimum of 12 hours.
Allow to cool, then detach the distillation flask. Proceed
to Section 10.1.4.
10.1.3.? 1.7 NOTE: Some continuous liquid-liquid extractors are also
capable of concentrating the oxtract within the extraction
set-up. Follow the manufacturer's instructions for
concentration when using this type of extractor.
10.1.3.2.2 Continuous Liquid-Liquid Extraction With Hydrophobic Membrane
10.1.3.2.2.1 Follow the manufacturer's instructions for set-up.
10.1.3.2.2.2 Measure out each 1 L sample aliquot in a separate, clean
graduated cylinder. If the sample was received in a 1 L
container, rinse the empty container with 50 mL of methylene
chloride and add the rinsate to the continuous extractor.
If the sample was not received in a 1 L container, add 50 mL
of methylene chloride to the continuous extractor. Slowly
transfer the aliquot to the continuous extractor. Measure
the pH of the sample with wide range pH paper and record pH.
Adjust the pH to between 5 and 9 with 10 N sodium hydroxide
or concentrated sulfuric acid, as required. Samples
requiring the pH adjustment must be noted in the SDG
Narrative.
10.1.3.2.2.3 Using a syringe or volumetric pipet, add 1.0 mL of the

extractor to ensure proper solvent cycling during operation.
Adjust the drip rate to 15 mL/minute (recommended); optimize
the extraction drip rate. Extract for a minimum of 6 hours.
(NOTE: Due to the smaller volume of solvent used during the
extraction process, some sample matrices (e.g., oily
samples, samples containing a high concentration of
surfactants) may create an emulsion which will consume the
solvent volume, preventing the efficient extraction of the
sample. When this occurs, add additional solvent to assure
efficient extraction of the sample, and extend the
extraction time for a minimum of 6 hours. If the sample
matrix prevents the free flow of solvent through the
membrane, then the non-hydrophobic membrane continuous
liquid-liquid type extractor must be used.) Allow to cool,
then detach the distillation flask.
10.1.3.2.2.6 NOTE: Some continuous liquid-liquid extractors are also
capable of concentrating the extract within the extraction
set-up. Follow the manufacturer's instructions for
concentration when using this type of extractor. Using the
hydrophobic membrane, it may not be necessary to dry the
extract with sodium sulfate.
10.1.3.2.3 NOTE: If low surrogate recoveries occur, assure 1) the
apparatus was properly assembled to prevent leaks; 2) the drip
rate/solvent cycling was optimized; and 3) there was proper
cooling for condensation of solvent.
10.1.3.2.4 NOTE: Alternate continuous liquid-liquid extractor types that
meet the requirements of the SOW may also be used. If using
alternate extractors or design types, follow the manufacturer's
instructions for set-up. Optimize the extraction procedure.
10.1.4 Extract Drying
10.1.4.1 Assemble a Kuderna-Danish (K-D) concentrator by attaching a 10 mL
concentrator tube to a 500 mL evaporative flask. Other
concentration devices or techniques may be used in place of the
K-D if equivalency is demonstrated for all the pesticide/Aroclor
target compounds listed in Exhibit C.
10.1.4.2 Pour the extract through a drying column containing about 10 cm of
anhydrous granular sodium sulfate and collect the extract in the
K-D concentrator. Rinse the Erlenmeyer flask and the column with
at least two additional 20 to 30 mL portions of methylene chloride
to complete the quantitative transfer.

10.1.5 Soil/Sediment Samples
Mix samples thoroughly, especially composited samples. Discard any
foreign objects such as sticks, leaves and rocks. Also, decant and
discard any standing aqueous phase.
10.1.5.1 pH Determination
10.1.5.1.1 Transfer 50 g of soil/sediment to a 100 mL beaker. Add 50 mL
of water and stir the solution with a magnetic stirrer for 1
hour. Determine the pH of the sample by using a combination
glass electrode and pH meter while the sample is stirred.
Report pH value on the appropriate data sheet. If the pH of
the soil/sediment is > 9 or < 5, document any subsequent
problems in the analysis related to pH in the SDG Narrative,
but do not attempt to adjust the pH of the sample. Discard the
portion of the sample used for pH determination.
10.1.5.1.2 NOTE: If insufficient volume of soil/sediment is received, use
a smaller 1:1 ratio of grams of sample to mLs of water for the
pH determination, and note in the SDG Narrative.
10.1.5.2 Percent Moisture
Weigh 5 to 10 g of the soil/sediment to the nearest 0.01 g into a
tared crucible or aluminum weighing pan. Determine the weight
percent volatilized by drying overnight at 105 °C (hereafter
referred to as percent moisture). After the sample is dry, remove
the sample and pan and allow them to cool in a desiccator before
weighing. Calculate the percent moisture according to Equation 11
below. Concentrations of individual analytes will be reported
relative to the dry weight of soil/sediment. CAUTION: Gases
volatized from some soil/sediment samples may require that this
drying procedure be carried out in a hood.

prior to extracting samples by this procedure.
10.1.5.3.2 Weigh approximately 30 g of sample (to the nearest 0.1 g) into
a 250 or 400 mL beaker and add 60 g of anhydrous sodium sulfate
(granular).
10.1.5.3.3 Add 2.0 mL of surrogate solution to all soil/sediment samples
by using a volumetric pipet or a syringe. Mix the sample well.

homogeneous, granular mixture at this point. (Twice as much of
the surrogate solution is added to soil/sediment samples than
to water samples.)
10.1.5.3.4 Immediately add 80 to 100 mL of 1:1 methylene chloride/acetone
to the sample.
10.1.5.3.5 Place the bottom surface of the sonicator probe about 1/2 inch
below the surface of the solvent but above the sediment layer.
10.1.5.3.6 Sonicate for 3 minutes using a 3/4 inch disruptor horn at full
power (output control knob at 10) with pulse on and percent
duty cycle knob set at 50 percent. Do not use a microtip.
NOTE: These settings refer to the Model W-385. When using a
sonicator other then Model W-385, refer to the instructions
provided by the manufacturer for appropriate output settings.
10.1.5.3.7 The extracted sample can be filtered by using gravity or vacuum
filtration.
10.1.5.3.8 For gravity filtration prepare a filtration/drying bed by
placing a plug of glass wool in the neck of a 10 cm powder
funnel and filling the funnel to approximately half its depth
(4 or 5 cm) with anhydrous sodium sulfate (80-100 g) . Decant
the extract through the packed funnel and collect it in a
500 mL evaporative (K-D) flask attached to a concentrator tube.
10.1.5.3.9 For vacuum filtration, use Whatman No. 41 paper in the Buchner
funnel. Pre-wet the paper with methylene chloride/acetone
before decanting the solvent.
10.1.5.3.10 Repeat the extraction two more times with additional 80 to
100 mL portions of the 1:1 methylene chloride/acetone. Before
each extraction, thoroughly mix the solid residue and make
certain that the sodium sulfate is free flowing and not a
consolidated mass. As required, break up large lumps with a
clean spatula. Decant and filter the extraction solvent after
each sonication by using the same funnel described above.
After the final sonication, pour the entire sample into the
funnel and rinse the beaker and funnel with 60 mL of 1:1
methylene chloride/acetone.
10.1.6 Concentrating the Extract
10.1.6.1 Concentration by K-D
Other concentration devices or techniques may be used in place of
the K-D if equivalency is demonstrated for all the
pesticide/Aroclor target compounds listed in Exhibit C.
10.1.6.1.1 Add one or two clean boiling chips to the evaporative flask and
attach a three-ball Snyder column. Pre-wet the Snyder column
by adding about 1 mL of methylene chloride to the top of the

column. Place the K-D apparatus on a hot water bath (60 °C to
70 °C recommended) so that the concentrator tube is partially
immersed in the hot water and the entire lower rounded surface
of the flask is bathed with hot vapor. Adjust the vertical
position of the apparatus and the water temperature as required
to complete the concentration in 15 to 30 minutes. At the
proper rate of distillation, the balls of the column will
actively chatter, but the chambers will not flood with
condensed solvent. When the apparent volume of liquid reaches
3 to 5 mL for water samples (and less than 10 mL for
soil/sediment samples), remove the K-D apparatus. Allow it to
drain and cool for at least 10 minutes. DO NOT ALLOW THE
EVAPORATOR TO GO DRY.
10.1.6.1.2 For water extracts which do not require GPC cleanup, and for
water and soil/sediment extracts which have been through the
GPC cleanup step, proceed with the hexane exchange described in
Section 10.1.6.2.
10.1.6.1.3 For water extracts which require GPC cleanup, remove the Snyder
column, rinse the flask and its lower joint, collect the
rinsate in the concentrator tube, and adjust the volume to
10 mL with methylene chloride. Proceed to Section 10.1.8.1.
10.1.6.1.4 For soil/sediment extracts that have not been cleaned-up using
GPC, it is absolutely necessary to further reduce the volume of
all soil/sediment extracts to 1 mL in order to remove most of
the acetone. This is best accomplished using the nitrogen
evaporation technique (Section 10.1.7.2). The presence of
acetone will cause a dead volume to develop in the GPC column
and thus will cause loss of surrogates and analytes during GPC
cleanups. Adjust the soil/sediment extract volume to 10 mL
with methylene chloride. Proceed to Section 10.1.8.1 for

10.1.6.2 Solvent Exchange into Hexane
This procedure applies to both extracts of water samples and
extracts of soil/sediment samples.
10.1.6.2.1 With the extract in a K-D apparatus, remove the Snyder column,
add 50 mL of hexane and a new boiling chip, and reattach the
Snyder column. Pre-wet the column by adding about 1 mL of
hexane to the top. Concentrate the solvent extract as
described previously (Section 10.1.6.1), but increase the
temperature of the water bath (to between 80 and 90 °C
recommended). When the apparent volume of liquid reaches 3 to
•5 mL, remove the K-D apparatus and allow it to drain and cool
for at least 10 minutes. DO NOT ALLOW THE EVAPORATOR TO GO
DRY.
10.1.6.2.2 Remove the Snyder column; using 1 to 2 mL of hexane, rinse the
flask and its lower joint into the concentrator tube. Complete

hexane.
10.1.6.2.3 For samples which have not been subjected to GPC cleanup,
adjust the volume of che hexane extract to 10 mL. For samples
which have been subjected to GPC cleanup, concentrate the
hexane extract to 5 mL using a micro Snyder column or nitrogen
evaporation, as described in Section 10.1.7.1 or 10.1.7.2.
Proceed to Section 10.1.8.2 for Florisil cartridge cleanup.
10.1.7 Final Concentration of Extract
Two different techniques are permitted to concentrate the extract to
volume before Florisil cleanup or extract volume before instrumental
analysis. They are the Micro Snyder Column and Nitrogen Evaporation
Technique.
10.1.7.1 Micro Snyder Column Concentration
Add another one or two clean boiling chips to the concentrator
tube and attach a two-ball micro Snyder column. Pre-wet the
Snyder column by adding about 0.5 mL of hexane to the top of the
column. Place the K-D apparatus in a hot water bath (80 °C to
90 °C recommended) so that the concentrator tube is partially
immersed in the hot water. Adjust the vertical position of the
apparatus and the water temperature as required to complete the
con, entration in 5 to 10 minutes. Ac the proper rate of
distillation the balls of the column will actively chatter but the
chambers will not flood with condensed solvent. When the
apparent volume of liquid reaches 0.5 mL, remove the K-D apparatus
from the water bath and allow it to drain for at least 10 minutes
while cooling. Remove the Snyder column and rinse its flask and
lower joint into the concentrator tube with 0.2 mL of hexane.
Adjust the final volume with hexane to 1 or 2 mL (see Sample
Cleanup by Florisil Cartridge, Section 10.1.8.2.3).
10.1.7.2 Nitrogen Evaporation Technique (taken from ASTM Method D 3086)
10.1.7.2.1 Place the concentrator tube in a warm water bath (30 °C to
35 °C recommended) and evaporate the solvent volume to the
final volume by blowing a gentle stream of clean, dry nitrogen
(filtered through a column of activated carbon) onto the
solvent. DO NOT ALLOW THE EXTRACT TO GO TO DRYNESS. Adjust
the soil/sediment extract volume to 10 mL with methylene
chloride. Proceed to Section 10.3 for mandatory GPC cleanup
procedures.
10.1.7.2.2 Gas lines from the gas source to the evaporation apparatus must
be stainless steel, copper, or Teflon tubing. Plastic tubing
must not be used between the carbon trap and the sample as it
may introduce interferences. The internal wall of new tubing
must be rinsed several times with hexane and then dried prior
to use.

Procedure
Cleanup Procedures
1C.1.7.2.3 During evaporation, the tube solvent level must be kept below
the water level of the bath.
10.1.8 Cleanup Procedures
There are three cleanup procedures specified in this method: GPC,
Florisil cartridge, and sulfur cleanup. GPC must be performed for
all soil/sediment extracts. GPC must be performed for water extracts
that contain higher molecular weight contaminants that interfere with
the analysis of the target analytes. Florisil cartridge cleanup is
mandatory for all extracts. Sulfur cleanup must be performed for all
sample extracts contaminated with sulfur. Blanks and matrix spike
and matrix spike duplicate samples must be subjected to the same
cleanup as the unspiked samples.
10.1.8.1 Sample Cleanup by Gel Permeation Chromatography (GPC)
10.1.8.1.1 Introduction
Gel Permeation Chromatography (GPC) is a size exclusion cleanup
procedure using organic solvents and hydrophobic gels in the
separation of natural (and synthetic) macromolecules. The
packing gel is porous and is characterized by the range or
uniformity (exclusion range) of that pore size. In the choice
of gels, the exclusion range must be larger than the molecular
size of the molecules to be separated.
10.1.8.1.2 GPC Column Preparation
The instructions listed below for GPC column preparation are
for Bio Beads. Alternate column packings may be used if 1) the
column packings have equivalent or better performance than the
Bio Beads and meet the technical acceptance criteria for GPC
calibration and GPC calibration checks, and 2) the column
packings do not introduce contaminants/artifacts into the
sample which interfere with the analysis of the pesticide
compounds. Follow the manufacturer's instructions for
preparation of the GPC column packing.
10.1.8.1.2.1 Weigh out 70 g of Bio Beads (SX-3). Transfer them to a 1 L
bottle with a Teflon-lined cap or a 500 mL separatory funnel
with a large bore stopcock, and add approximately 300 mL of
methylene chloride. Swirl the container to ensure the
wetting of all beads. Allow the beads to swell for a
minimum of 2 hours. Maintain enough solvent to cover the
beads sufficiently at all times. If a guard column is to be
used, repeat the above with 5 g of Bio Beads in a 125 mL
bottle or a beaker, using 25 mL of methylene chloride.
10.1.8.1.2.2 Turn the column upside down from its normal position and
remove the inlet bed support plunger (the inlet plunger is
longer than the outlet plunger). Position and tighten the
outlet bed support plunger as near the end as possible, but
D-43/PEST OLM3.0

Procedure
Cleanup Procedures
no closer than 5 cm (measured from the gel packing to the
collar).
10.1.8.1.2.3 Raise the end of the outlet tube to keep the solvent in the
GPC column, or close the column outlet stopcock. Place a
small amount of solvent in the column to minimize the
formation of air bubbles at the base of poured column
packing.
10.1.8.1.2.4 Swirl the bead/solvent slurry to get a homogeneous mixture
and, if the wetting was done in a quart bottle, quickly
transfer it to a 500 mL separatory funnel with a large bore
stopcock. Drain the excess methylene chloride directly into
the waste beaker, and then start draining the slurry into
the column by placing the separatory funnel tip against the
column wall. This will help to minimize bubble formation.
Swirl occasionally to keep the slurry homogeneous. Drain
enough to fill the column. Place the tubing from the column
outlet into a waste beaker below the column, open the
stopcock (if attached), and allow the excess solvent to
drain. Raise the tube to stop the flow, and close the
stopcock when the top of the gel begins to look dry. Add
additional methylene chloride to just rewet the gel.
10.1.8.1.2.5 Wipe any remaining beads and solvent from the inner walls of
the top of the column with a laboratory tissue. Loosen the
seal slightly on the other plunger assembly (long plunger)
and insert it into the column. Make the seal just tight
enough so that any beads on the glass surface will be pushed
forward, but loose enough so that the plunger can be pushed
forward.
CAUTION: Do not tighten the seal if beads are between the
seal and the glass surface because this can damage the seal
and cause leakage.
10.1.8.1.2.6 Compress the column as much as possible without applying
excessive force. Loosen the seal and gradually pull out the
plunger. Rinse and wipe off the plunger. Slurry any
remaining beads and transfer them into the column. Repeat
the step in Section 10.1.8.1.2.5 and reinsert the plunger.
If the plunger cannot be inserted and pushed in without
allowing beads to escape around the seal, continue
compression of the beads without tightening the seal, and
loosen and remove the plunger as described. Repeat this
procedure until the plunger is inserted successfully.
10.1.8.1.2.7 Push the plunger until it meets the gel, then compress the
column bed about four centimeters.
10.1.8.1.2.8 Pack the optional 5 cm column with approximately 5 g of pre-
swelled beads (different guard columns may require different
D-44/PEST OLM3.0

Procedure
Cleanup Procedures
amounts). Connect the guard column to the inlet of the
analytical column.
10.1.8.1.2.9 Connect the column inlet to the solvent reservoir (reservoir
should be placed higher than the top of the column) and
place the column outlet tube in a waste container. Placing
a restrictor in the outlet tube will force air out of the
column more quickly. A restrictor can be made from a piece
of capillary stainless steel tubing of 1/16" OD x 0.010" ID
x 2". Pump methylene chloride through the column at a rate
of 5 mL/min for one hour.
10.1.8.1.2.10 After washing the column for at least one hour, connect the
column outlet tube, without the restrictor, to the inlet
side of the UV detector. Connect the system outlet to the
outlet side of the UV detector. A restrictor (same size as
the one in 10.1.8.1.2.9 above) in the outlet tube from the
UV detector will prevent bubble formation which causes a
noisy UV baseline. The restrictor will not affect flow
rate. After pumping methylene chloride through the column
for an additional 1-2 hours, adjust the inlet bed support
plunger until approximately 6-10 psi backpressure is
achieved. Push the plunger in to increase pressure or
slowly pull outward to reduce pressure.
10.1.8.1.2.11 When the GPC column is not to be used for several days,
connect the column outlet line to the column inlet to
prevent column drying and/or channeling. If channeling
occurs, the gel must be removed from the column, reswelled,
and repoured as described above. If drying occurs,
methylene chloride should be pumped through the column until
the observed column pressure is constant and the column
appears wet. Always recalibrate after column drying has
occurred to verify retention volumes have not changed.
NOTE: The description of solvent flow rate and column
pr-essure applies only to the ABC GPC apparatus.
Laboratories using equivalent equipment must develop the
parameters for their apparatus which give acceptable
performance as described in Section 10.1.8.1.3.
10.1.8.1.3 Calibration of GPC
10.1.8.1.3.1 Summary of GPC Calibration
10.1.8.1.3.1.1 The GPC calibration procedure is based on monitoring the
elution of standards with a UV detector connected to the
GPC column.
10.1.8.1.3.1.2 The UV detector calibration procedure described in
10.1.8.1.3.3 is to be used for the analyses of
organochlorine pesticides and Aroclors listed in Exhibit
C. IT MUST NOT BE USED FOR THE ANALYSIS OF GC/MS
EXTRACTABLES OR OTHER ANALYTES WITHOUT A RECOVERY STUDY.
D-45/PEST OLM3.0

Exhibit D Pesticides/Aroclors — Section 10
Procedure
Cleanup Procedures
10.1.8.1.3.2 Frequency of GPC Calibration
Each GPC system must be initially calibrated upon award of
the contract, when the GPC check solution fails to meet
criteria, when the column is changed, or when channeling
occurs.
10.1.8.1.3.3 Procedure for GPC Calibration
The following instructions are for the Analytical
Biochemical Laboratories (ABC) system. If you are using a
different GPC system, consult the manufacturer's instruction
manual for operating instructions. A 2 mL injection loop
may be used in place of a 5 mL injection loop in accordance
with the manufacturer's instructions.
10.1.8.1.3.3.1 Verify the flow rate by collecting column eluate for 10
minutes in a graduated cylinder and measure the volume,
which should be 45-55 mL (4.5-5.5 mL/min). Once the flow
rate is within the required range, record the column
pressure (should be 6-10 psi) and room temperature.
Changes in pressure, solvent flow rate, and temperature
conditions can affect analyte retention times and must be
monitored.
10.1.8.1.3.3.2 Using a 10 mL syringe, load sample loop #1 with
calibration solution (Section 7.2.4.3). With the ABC
automated system, the 5 mL sample loop requires a minimum
of 8 mL of the calibration solution. Use a firm,
continuous pressure to push the sample onto the loop.
Switch the valve so that GPC flow is through the UV flow-
through cell.
10.1.8.1.3.3.3 Inject the calibration solution and obtain a UV trace
showing a discrete peak for each component. Adjust the
detector and/or recorder sensitivity to produce a UV
trace that meets the requirements in Section
10.1.8.1.3.4. Differences between manufacturer's cell
volumes and detector sensitivities may require a dilution
of the calibration solution to achieve similar results.
An analytical flow-through detector cell will require a
much less concentrated solution than the semi-prep cell
and, therefore, the analytical flowthrough detector cell
is not acceptable for use.
10.1.8.1.3.3.4 Determine the elution times for the phthalate,
methoxychlor, and perylene. Phthalate will elute first,
perylene, last.
10.1.8.1.3.3.5 Choose a "DUMP" time which removes > 85 percent of the
phthalate. Choose a "COLLECT" time so that > 95 percent
of the methoxychlor is collected, and continue to collect
D-46/PEST OLM3.0

Cleanup Procedures
until just prior to the elution time of sulfur. Use a
"WASH" time of 10 minutes.
NOTE: The DUMP and COLLECT times must be adjusted to
compensate for the difference in volume of the lines
between the detector and the collection flask.
10.1.8.1.3.3.6 Reinject the calibration solution after appropriate
collect and dump cycles have been set, and the solvent
flow and column pressure have been established.
10.1.8.1.3.3.7 Measure and record the volume of collected GPC eluate in
a graduated cylinder. The volume of GPC eluate collected
for each sample extract processed may be used to
indicate problems with the system during sample
processing.
10.1.8.1.3.3.8 Analyze a GPC blank by loading 5 mL of methylene chloride
into the GPC. Concentrate the methylene chloride that
passes through the system during the collect cycle using
Kuderna-Danish (K-D) evaporator. Exchange the solvent to
hexane and analyze the concentrate by GC/EC according to
the procedure in 10.2 (usual protocol). Assuming that
the blank represents the extract from a 1 L water sample,
calculate the analyte concentrations using Eguation 13.
10.1.8.1.3.4 Technical Acceptance Criteria for GPC Calibration
10.1.8.1.3.4.1 The GPC system must be calibrated at the frequency
described in Section 10.1.8.1.3.2. The UV trace must
meet the following requirements:
• Peaks must be observed and should be symmetrical for
all compounds in the calibration solution.
• Corn oil and phthalate peaks must exhibit > 85 percent
resolution.
• Phthalate and methoxychlor peaks must exhibit > 85
percent resolution.
• Methoxychlor and perylene peaks must exhibit > 85
percent resolution.
• Perylene and sulfur peaks must not be saturated and
must exhibit > 90 percent baseline resolution.
10.1.8.1.3.4.2 The solvent flow rate and column pressure must be within
the ranges described in Section 10.1.8.1.3.3.1.
10.1.8.1.3.4.3 The retention times for bis (2-ethylhexyl) phthalate and
perylene must not vary more than ± 5 percent between
calibrations. If the retention time shift is > 5
D-47/PEST OLM3.0
-------
Exhibit D Pesticides/Aroclors — Section 10
Procedure
Cleanup Procedures
percent, take corrective action. Excessive retention
time shifts are caused by the following:
• Poor laboratory temperature control or system leaks.
• An unstabilized column that requires pumping methylene
chloride through it for several more hours or
overnight.
• Excessive laboratory temperatures causing outgassing
of the methylene chloride.
10.1.8.1.3.4.4 The analyte concentrations in a GPC blank must be less
than the CRQL of any compound in Exhibit C (Pesticides).
10.1.8.1.3.5 Corrective Action for GPC Calibration
10.1.8.1.3.5.1 If the flow rate and/or column pressure do not fall
within the ranges in Section 10.1.8.1.3.3.5, a new column
should be prepared.
10.1.8.1.3.5.2 AUV trace that does not meet the criteria in Section
10.1.8.1.3.4 would also indicate that a new column should
be prepared. It may be necessary to obtain a new lot of
Bio Beads if the column fails all the criteria.
10.1.8.1.3.5.3 If the GPC blank is equal to or exceeds the CRQL of any
compound in Exhibit C (Pesticides), pump additional
methylene chloride through the system for 1-2 hours.
Analyze another GPC blank to ensure the system is
sufficiently clean. Repeat the methylene chloride
pumping if necessary.
10.1.8.1.4 GPC Calibration Check
10.1.8.1.4.1 Summary of GPC Calibration Check
The GPC calibration must be routinely verified with two
check mixtures. No Florisil cleanup is used in the GPC
calibration check.
10.1.8.1.4.2 Frequency of GPC Calibration Check
10.1.8.1.4.2.1 The calibration check must be performed at least once
every 7 days whenever samples, including matrix spikes,
matrix spike duplicates, and blanks are cleaned up using
the GPC.
10.1.8.1.4.2.2 Some samples may contaminate the SX-3 Bio Beads and
change the retention volume of the GPC column.
Therefore, system calibration and analyte recovery must
be checked whenever a sample causes significant
discoloration of the GPC column. Even if no darkening is
D-48/PEST OLM3.0

Procedure
Cleanup Procedures
visible, GPC calibration must be checked not less than
once every seven days. In many cases, the SX-3 Bio Beads
may be used for several months as long as the column
calibration and flow rate remain constant.
10.1.8.1.4.3 Procedure for GPC Calibration Check
The instructions below are for a GPC injection loop of 5 mL.
If a 2 mL injection loop is used, the Contractor will adjust
the volume to 4 mL instead of 10 mL before injecting extract
on the GPC.
10.1.8.1.4.3.1 The pesticide GPC calibration check solution contains the
following six compounds in methylene chloride: gamma-
BHC, Hepatachlor, and Aldrin each at a concentration of
0.1 iig/mL for a 5 mL GPC loop (0.25 ng/mL when a 2 mL GPC
loop is used) and 4,4 '-DDT, Endrin and Dieldrin at 0.2
jig/mL (0.25 ^g/mL for a 2 mL loop). The Aroclor mixture
contains 2 ng/mL each of Aroclor 1016 and 1260 in
methylene chloride (0.25 ng/mL when a 2 mL GPC loop is
used).
10.1.8.1.4.3.2 Load the first 5 mL sample loop by using a 10 mL syringe
containing 8 tnL of the pesticide GPC calibration check
solution. The Aroclor mixture is loaded into loop #2 in
the same manner. Fractions are collected in an auto
sequence by using the GPC program established by the UV
detector calibration procedure (Section 10.1.8.1.3).
10.1.8.1.4.3.3 The collected GPC calibration fraction is transferred to
a K-D apparatus, and the collection vessel is rinsed with
two additional 10 mL portions of methylene chloride to
complete the transfer. The volume of methylene chloride
is reduced according to Section 10.1.6.1. After cooling,
the solvent is exchanged to hexane according to the
instructions in Section 10.1.6.2. The final volume is
adjusted to 10 mL, and the sample is analyzed by GC
according to the procedure in Section 10.2 (usual
protocol). The analysis must be performed on only one of
the GC columns used for sample analysis.
10.1.8.1.4.3.4 The pattern of the Aroclor quantitation peaks and the
recovery of each single component analyte must be
determined for evaluation and reporting purposes.
10.1.8.1.4.4 Technical Acceptance Criteria for GPC Calibration Check
10.1.8.1.4.4.1 The GPC must meet the technical acceptance criteria for
GPC calibration in Section 10.1.8.1.3.4 and be calibrated
at the frequency listed in Section 10.1.8.1.4.2.
10.1.8.1.4.4.2 The recovery of each of the single component analytes
must be between 80 - 110 percent.
D-49/PEST OLM03.1

Exhibit D Pesticides/Aroclors — Section 10
Procedure
Cleanup Procedures
10.1.8.1.4.4.3 The Aroclor patterns must be the same as those from the
Aroclor 1016 and Aroclor 1260 standards in the initial
calibration sequence.
10.1.8.1.4.5 Corrective Action for GPC Calibration Check
Analysts may continue to use the GPC column if the technical
acceptance criteria for the GPC calibration check are met.
If the recoveries are out of the acceptance window or if
changes in the relative peak heights of the patterns of the
Aroclor are observed, the columns must be replaced and the
GPC recalibrated according to the instructions in Section
10.1.8.1.3 before proceeding with any GPC cleanup on
samples, including blanks - method and/or sulfur and MS/MSD.
10.1.8.1.5 Daily UV Calibration Check (Optional)
The calibration of the GPC may be monitored daily by use of the
UV-GPC calibration solution (Section 7.2.4.3) and the UV
detector calibration procedure (Section 10.1.8.1.3.3). The UV
detector should be used to monitor the elution times for the
phthalate, methoxychlor and perylene, in that order. The pre-
calibrated GPC program should "dump" > 85 percent of the
phthalate and should "collect" > 95 percent of the methoxychlor
and perylene. Significant changes in elution times of the
analytes (e.g., > 0.5 minutes) indicate that the column is out
of calibration and must be recalibrated or replaced.
10.1.8.1.6 Sample Cleanup by GPC
10.1.8.1.6.1 Introduction to Sample Cleanup by GPC
10.1.8.1.6.1.1 It is very important to have consistent laboratory
temperatures during an entire GPC run, which could be 24
hours or more. If temperatures are not consistent,
retention times will shift, and the dump and collect
times determined by the calibration standard no longer
will be appropriate. The ideal laboratory temperature to
prevent outgassing of the methylene chloride is 22 °C.
10.1.8.1.6.1.2 In order to prevent overloading of the GPC column, highly
viscous sample extracts must be diluted prior to cleanup.
Any sample extract with a viscosity greater than that of
1:1 glycerol:water solution must be diluted and loaded
into several loops. Similarly, extracts containing more
than 40 mg/mL of nonvolatile residue must be diluted and
loaded into several loops. The nonvolatile residue may
be determined by evaporating a 100 /xL aliquot of the
extract to dryness in a tared aluminum weighing pan, or
other suitable container. When multiple loops/runs are
necessary for an individual sample, be sure to combine
all of the sample eluates collected.

Procedure
Cleanup Procedures
10.1.8.1.6.1.3 Systems using automated injection devices to load the
sample on the column must be carefully monitored to
assure that the required amount is injected onto the
column. Viscous extracts, or extracts containing a large
amounts of nonvolatile residue, will cause problems with
injecting the proper amount of sample extract onto the
column using automated injection systems. After the
sample extract has been processed, the remaining sample
extract in an injection vial must be checked to assure
that the proper amount of extract was injected on the
column before proceeding with the sample analysis. If
the proper amount of extract was not injected, the sample
must be reprepared and the sample extract must be either
diluted and loaded into several loops or the sample
extract must be injected manually.
10.1.8.1.6.2 Frequency of Sample Cleanup by GPC
GPC cleanup must be performed at least once for each
soil/sediment extract, water extracts that contain high
molecular weight contaminants that interfere with the
analysis of the target analytes and all associated QC
(blanks and spikes). If cleanup procedure is inadequate
contact SMO.
10.1.8.1.6.3 Procedure for Sample Cleanup by GPC
10.1.8.1.6.3.1 Particles greater than 5 microns may scratch the valve,
which may result in a system leak and cross contamination
of sample extracts in the sample loops. To avoid such
problems, filter the extract through a 5 micron filter
disc by attaching a syringe filter assembly containing
the filter disc to a 10 mL syringe. Draw the sample
extract through the filter assembly and into the 10 mL
syringe. Disconnect the filter assembly before
transferring the sample extract into a small glass
container (e.g., a 15 mL culture tube with a Teflon-lined
screw cap). Alternatively, draw the extract into the
syringe without the filter assembly. Attach the filter
assembly and force the extract through the filter and
into the glass container. Draw a minimum of 8 mL of
extract into a 10 mL syringe.
Note: Some GPC instrument manufacturer's recommend using
a smaller micron size filter disc. In this instance,
follow the manufacturer's recommended operating
instructions.

Cleanup Procedures
10.1.8.1.6.3.3 The following instructions are for the Analytical
Biochemical Laboratories (ABC) system. If you are using
a different GPC system, consult your manufacturer's
instruction manual for operating instructions. Note:
These instructions were written for a 5 mL GPC injection
loop. A 2 mL injection loop may be used in place of a 5
mL injection loop. If a 2 mL loop is used, concentrate
the 10 mL extract to 4 mL, and then inject 2 mL from the
4 mL.
10.1.8.1.6.3.4 Prior to loading samples, put the GPC into the "load"
mode, set the instrument terminal for the number of loops
to be loaded, and set the "dump," "collect," and "wash"
times for the values determined by the calibration
procedure described in Section 10.1.8.1.3.
10.1.8.1.6.3.5 Using a 10 mL syringe, load ^he sample into the system.
With the ABC automated system, the 5 mL loop requires a
minimum of 8 mL of sample. Attach the syringe to the
turn lock on the injection port. Use firm, continuous
pressure to push the sample onto the 5 mL sample loop.
If the sample is difficult to load, some part of the
system may be blocked. Take appropriate corrective
action. If the back pressure is normal (6-10 psi), the
blockage is probably in the valve. Blockage may be
flushed out of the valve by reversing the inlet and
outlet tubes and pumping solvent through the tubes (this
should be done before sample loading). NOTE:
Approximately 2 mL of the extract remains in the lines
between the injection port and the sample loop; excess
sample also passes through the sample loop to waste.
10.1.8.1.6.3.6 After loading a loop, and before removing the syringe
from the injection port, index the GPC to the next loop.
This will prevent loss of sample caused by unequal
pressure in the loops.
10.1.8.1.6.3.7 After loading each sample loop, wash the loading port
with methylene chloride in a PTFE wash bottle to minimize
cross contamination. Inject approximately 10 mL of
methylene chloride to rinse the common tubes.
10.1.8.1.6.3.8 After loading all sample loops, index the GPC to the 00
position, switch to the "RUN" mode and start the
automated sequence. Process each sample using the
collect and dump cycle times established in Section
10.1.8.1.3.
10.1.8.1.6.3.9 Collect each sample in a 250 mL Erlenmeyer flask covered
with aluminum foil to reduce solvent evaporation, or
directly into a Kuderna-Danish evaporator. Monitor
sample volumes collected. Changes in sample volumes

collected may indicate one or more of the following
problems:
• Change in solvent flow rate, caused by channeling in
the column or changes in column pressure.
• Increase in column operating pressure due to the
absorption of particles or gel fines onto either the
guard column or the analytical column gel, if a guard
column is not used.

10.1.8.1.6.3.10 After the appropriate GPC fraction has been collected for
each sample, concentrate the extract as per Section 10.1.6.1
and proceed to solvent exchange into hexane as described in
Section 10.1.6.2 and Florisil cleanup in 10.1.8.2.
10.1.8.1.6.3.11 Any samples that were loaded into two or more loops must be
recombined before proceeding with concentration.
10.1.8.2 Florisil Cleanup
10.1.8.2.1 Introduction
lorisil cartridge cleanup significantly reduces matrix
interference caused by polar compounds and is required for all
extracts. The same volume of the concentrated extract taken
for Florisil cleanup must be maintained after Florisil cleanup
(1 or 2 mL).
10.1.8.2.2 Florisil Cartridge Performance Check
10.1.8.2.2.1 Summary of Florisil Cartridge Performance Check
Every lot number of Florisil cartridges must be tested
before they are used for sample cleanup.
10.1.8.2.2.2 Frequency of Florisil Cartridge Performance Check
Cartridge performance check must be conducted at least once
on each lot of cartridges used for sample cleanup.
10.1.8.2.2.3 Procedure for Florisil Cartridge Performance Check
Add 0.5 mL of 2,4,5-trichlorophenol solution (0.1 ng/mL in
acetone, Section 7.2.4.4) and 0.5 mL of Standard Mixture A,
midpoint concentration, Section 7.2.4.7) to 4 mL of hexane.
Reduce the final volume to 0.5 mL using nitrogen (Section
10.1.7.2). Place the mixture onto the top of a washed
Florisil cartridge, and elute it with 9 mL of hexane/acetone
[(90:10)(V/V)]. Use two additional 1 mL hexane rinses to

ensure quantitative transfer of standard from the cartridge.
Reduce the final volume to 1 mL using nitrogen (Section
10.1.7.2) and analyze the solution by GC/EC using at least
one of the GC columns specified for sample analysis.
Determine the recovery of each analyte for evaluation and
reporting purposes. Calculate the percent recovery using

10.1.8.2.2.4 Technical Acceptance Criteria for Florisil Cartridge
Performance Check
10.1.8.2.2.4.1 The cartridge performance check solution must be analyzed
on a GC/EC meeting the initial calibration and
calibration verification technical acceptance criteria.
10.1.8.2.2.4.2 The lot of Florisil cartridges is acceptable if all
pesticides are recovered at 80 to 120 percent, if the
recovery of trichlorophenol is less than 5 percent, and
if no peaks interfering with the target analytes are
detected.
10.1.8.2.2.5 Corrective Action for Florisil Cartridge Performance Check
Any lot of Florisil cartridges that does not meet the
criteria above must be discarded and a new lot, meeting
criteria, used for sample cleanup.
10.1.8.2.3 Sample Cleanup by Florisil Cartridge
The required Florisil cartridge size and the final volume of
the extract after Florisil cleanup are a function of the GC
autosampler that a laboratory uses. If the autosampler
operates reliably with 1 mL of sample extract, then a 500 mg
cartridge is used and the required final volume is 1 mL. If
the autosampler requires more sample, prepare 2 mL of sample
extract using a 1 g cartridge. Manual injection requires only
a 1 mL final extract and a 500 mg cartridge.

Procedure
Cleanup Procedures
All sample extracts are required to be cleaned up by the
Florisil cartridge technique.
10.1.8.2.3.2 Procedure for Sample Cleanup by Florisil Cartridge
10.1.8.2.3.2.1 Attach the vacuum manifold to a water aspirator or to a
vacuum pump with a trap installed between the manifold
and the vacuum source. Adjust the vacuum pressure in the
manifold to between 5 and 10 pounds of vacuum.
10.1.8.2.3.2.2 Place one Florisil cartridge into the vacuum manifold for
each sample extract.
10.1.8.2.3.2.3 Prior to cleanup of samples, the cartridges must be
washed with hexane/acetone (90:10). This is accomplished
by placing the cartridge on the vacuum manifold, by
pulling a vacuum, and by passing at least 5 mL of the
hexane/acetone solution through the cartridge. While the
cartridges are being washed, adjust the vacuum applied to
each cartridge so that the flow rate through each
cartridge is approximately equal. DO NOT ALLOW THE
CARTRIDGES TO GO DRY AFTER THEY HAVE BEEN WASHED.
10.1.8.2.3.2.4 After the cartridges on the manifold are washed, the
vacuum is released, and a rack containing labeled 10 mL
volumetric flasks is placed inside the manifold. Care
must be taken to ensure that the solvent line from each
cartridge is placed inside of the appropriate volumetric
flask as the manifold top is replaced.
10.1.8.2.3.2.5 After the volumetric flasks are in place, the vacuum to
the manifold is restored, and a volume of extract equal
to the required final volume (1 or 2 mL) from each
sample, blank or matrix spike extract is transferred to
the top frit of the appropriate Florisil cartridge. This
must equal the final volume after Florisil cleanup.
10.1.8.2.3.2.6 Because the volumes marked on concentrator tubes are not
necessarily accurate at the 1 mL level, the use of a
syringe or a volumetric pipet is required to transfer the
extract to the cleanup cartridge.
10.1.8.2.3.2.7 The pesticides/Aroclors in the extract concentrates are
then eluted through the column with 8 mL of
hexane/acetone (90:10) and are collected into the 10 mL
volumetric flasks held in the rack inside the vacuum
manifold.
10.1.8.2.3.2.8 Transfer the eluate in each volumetric flask to a clean
centrifuge tube or 10 mL vial. Use two additional 1 mL
hexane rinses to ensure quantitative transfer of the
cartridge eluate.

Cleanup Procedures
10.1.8.2.3.2.9 Adjust the extract to the same 1 or 2 mL aliquot volume
as was taken for cleanup using either nitrogen blowdown
(Section 10.1.7.2) or a micro Snyder column (Section
10.1.7.1). Measure the final volume with a syringe or by
transferring the extract to a volumetric flask.
10.1.8.2.3.2.10 If sulfur cleanup is to be performed, proceed to Section
10.1.8.3. Otherwise, transfer the sample to a GC vial
and label the vial. The extract is ready for GC/EC
analysis.
10.1.8.3 Sulfur Cleanup
10.1.8.3.1 Introduction to Sulfur Cleanup
10.1.8.3.1.1 Sulfur contamination will cause a rise in the baseline of a
chromatogram and may interfere with the analyses of the
later eluting pesticides. If crystals of sulfur are evident
or if the presence of sulfur is suspected, sulfur removal
must be performed. Interference which is due to sulfur is
not acceptable. Sulfur can be removed by one of two
methods, according to laboratory preference. If the sulfur
concentration is such that crystallization occurs in the
concentrated extract, centrifuge the extract to settle the
crystals, and remove the sample extract with a disposable
pipette, leaving the excess sulfur in the centrifuge tube.
Transfer the extract to a clear, centrifuge tube or clean
concentrator tube before proceeding with further sulfur
cleanup.
10.1.8.3.1.2 If only part of a set of samples require sulfur cleanup,
then, a sulfur cleanup blank is required for that part of
the set (Section 12.1.3).
10.1.8.3.2 Frequency of Sulfur Cleanup
Sulfur removal is required for all sample extracts that contain
sulfur.
10.1.8.3.3 Procedure for Sulfur Cleanup
10.1.8.3.3.1 Mercury Technique
Add one to three drops of mercury to each hexane extract in
a clean vial. Tighten the top on the vial and agitate the
sample for 30 seconds. Filter or centrifuge the extract.
Pipet the extract to another vial and leave all solid
precipitate and liquid mercury. If the mercury appears
shiny, proceed to Section 10.2 and analyze the extract. If
the mercury turns black, repeat sulfur removal as necessary.
The extract transferred to the vial still represents the 1.0
or 2.0 mL final volume. CAUTION: Waste containing mercury
should be segregated and disposed of properly. NOTE:

Procedure
GC/EC Analysis
Mercury is a highly toxic metal and therefore must be used
with great care. Prior to using mercury, it is recommended
that the analyst become acquainted with proper handling and
cleanup techniques associated with this metal.
10.1.8.3.3.2 Copper Technique
Add approximately 2 g of cleaned copper powder to the
extract in the centrifuge or concentrator tube (2 g will
fill the tube to about the 0.5 mL mark). Mix the copper and
extract for at least 1 minute on a mechanical shaker.
Separate the extract from the copper powder by drawing off
the extract with a disposable pipet, and transfer the
extract to a clean vial. The extract transferred to the
vial still represents the 1.0 or 2.0 mL final volume. The
separation of the extract from the copper powder is
necessary to prevent degradation of the pesticides. If the
copper appears bright, proceed to Section 10.2 and analyze
the extracts. If the copper changes color, repeat the
sulfur removal procedure as necessary.
10.2 GC/EC Analysis
10.2.1 Introduction to Sample Analysis by GC/EC
10.2.1.1 Before samples or required blanks can be analyzed, the instrument
must meet the initial calibration and calibration verification
technical acceptance criteria. Sample analysis on both GC columns
is required for all samples, blanks, matrix spikes, and matrix
spike duplicates.
10.2.1.2 Sample extracts, standards and blanks must be analyzed within an
analytical sequence as defined in Section 10.2.2.1, under the same
instrumental conditions.
10.2.1.3 Set up the GC/EC system per the requirements in Section 9.0.
Unless ambient temperature on-column injection is used (see
Section 9.1.4), the injector must be heated to at least 200 °C.
The optimized gas chromatographic conditions from Section 9.1 must
be used,
10.2.2 Procedure for Sample Analysis by GC/EC
The injection must be made on-column by using either automatic or
manual injection. If autoinjectors are used, 1 fiL injection volumes
may be used. Manual injections shall use at least 2 jtL injection
volumes. The same injection volume must be used for all standards,
samples, MS/MSD, and blanks associated with the same initial
calibration. If a single injection is used for two GC columns
attached to a single injection port, it may be necessary to use an
injection volume greater than 2 /xL. However, the same injection
volume must be used for all analyses.

10.2.2.1.1 NOTE: The first 12 hours are counted from injection #16 (the
instrument blank at the end of the initial calibration
sequence), not from injection #1. Samples may be injected
until 12 hours have elapsed. All subsequent 12-hour periods
are timed from the injection of the instrument blank that
brackets the front end of the samples. Because the 12-hour
time period is timed from injection of the instrument blank
until the injection of the last sample, each 12-hour period may
be separated by the length of one chromatographic run, that of
the analysis of the last sample. While the 12-hour period may
not be exceeded, the laboratory may run instrument blanks and
standards more frequently for instance, to accommodate staff
working 8-hour shifts.
10.2.2.1.2 After the initial calibration, the analysis sequence may
continue as long as acceptable instrument blanks, PEMs and
Individual Standard Mixtures A and B are analyzed at the
required frequency. This analysis sequence shows only the
minimum required blanks and standards. More blanks and
standards may be run at the discretion of the Contractor; uhese
must also satisfy the criteria presented in Section 9 in order
to continue the run sequence.
10.2.2.1.3 An analysis sequence must also include all required matrix
spike/matrix spike duplicate and method (and/or sulfur) blank
analyses, but the Contractor may decide at what point in the
sequence they are to be analyzed.
10.2.2.1.4 The requirements for the analysis sequence apply to both GC
columns and for all instruments used for these analyses.
10.2.3 Sample Dilutions
10.2.3.1 All samples must be analyzed at the most concentrated level that
is consistent with achieving satisfactory chromatography (defined
in Section 11.3).
10.2.3.2 If the response of any single component pesticide is greater than
the response of that analyte in the initial calibration high point

standard, then the extract must be diluted to have the response of
that analyte between the initial calibration low point and high
point standards.
10.2.3.3 If the response of the largest peak in a multicomponent analyte is
greater than the most intense single component analyte response in
the initial calibration high point standard, then the sample must
be diluted to have the response of the largest peak in the
multicomponent analyte between the responses of the initial
calibration midpoint and high point standards of that single
component pesticide.
10.2.3.4 If dilution is employed solely to bring a peak within the
calibration range or to get a multicomponent pattern on scale, the
results for both the more and the less concentrated extracts must
be reported. The resulting changes in quantitation limits and
surrogate recovery must be reported also for the diluted samples.
10.2.3.5 If the Contractor has reason to believe that diluting the final
extracts will be necessary, an undiluted run may not be required.
If an acceptable chromatogram (as defined in Section 11.3) is
achieved with the diluted extract, an additional extract 10 times
more concentrated than the diluted sample must be injected and
reported with the sample data.
10.2.3.6 When diluted, the chromatographic data for the single component
pesticides must be able to be reported at greater than 10.0
percent of full scale but less than 100.0 percent of full scale.
10.2.3.7 When diluted, multicomponent analytes must be able to be reported
at greater than 25.0 percent of full scale but less than 100.0
percent of full scale.
10.2.3.8 If a chromatogram is replotted electronically to meet these
requirements, the scaling factor used must be displayed on the
chromatogram. If the chromatogram of any sample needs to be
replotted electronically to meet these requirements both the
initial chromatogram and the replotted chromatogram must be
submitted in the data package.
10.2.3.9 Samples with analytes detected at a level greater than the high
calibration point must be diluted until the response is within the
linear range established during calibration or to a maximum of
1:100,000.
10.2.3.10 If the response is still above the high calibration point after
the dilution of 1:100,000, the Contractor shall contact SMO
immediately.
10.2.3.11 Use the results of the original analysis to determine the
approximate dilution factor required to get the largest analyte
peak within the initial calibration range.

10.2.3.12 The dilution factor chosen should keep the response of the largest
peak for a target compound in the upper half of the initial
calibration range of the instrument.
10.2.3.13 Sample dilutions must be made quantitatively. Dilute the sample
extract with hexane.
10.2.3.14 Do not submit data for more than two analyses, i.e., the original
sample extract and one dilution, or, if a screening procedure was
employed, from the most concentrated dilution analyzed and one
further dilution. This statement does not refer to reanalyses
required due to failed technical acceptance criteria.

Data Analysis and Calculations
Qualitative Identification
11.0 DATA ANALYSIS AND CALCULATIONS
11.1 Qualitative Identification
11.1.1 Identification of Target Compounds
11.1.1.1 The laboratory will identify and quantitate analyte peaks based on
the RT windows and the calibration factors of the midpoint
standard (single component pesticides) established during the
initial calibration sequence.
11.1.1.2 Analytes are identified when peaks are observed in the RT window
for the analyte on both GC columns.
11.1.1.3 A set of three to five major peaks is selected for each
multicomponent analyte. The retention time window for each peak
is determined from the initial calibration analysis.
Identification of a multicomponent analyte in the sample is based
on pattern recognition in conjunction with the elution of three to
five sample peaks within the retention time windows of the
corresponding peaks of the standard on both GC columns.
Calibration factors used to quantitate toxaphene and the Aroclors
are based on the single-point calibration standard analyzed during
the initial calibration. The number of potential quantitation
peaks is listed in Table 2.
11.1.1.4 When any multicomponent analyte is detected in a sample, a
standard must be run within 72 hours of the analyte's detection
(from time of injection), and within a valid 12-hour sequence.
11.1.1.5 The choice of the peaks used for multicomponent analyte
identification and the recognition of those peaks may be
complicated by the environmental alteration of the toxaphene or
Aroclors, and by the presence of co-eluting analytes or matrix
interferences, or both. Because of the alteration of these
materials in the environment, multicomponent analytes in samples
may give patterns similar to, but not identical with, those of the
standards.
11.1.1.6 If more than one multicomponent analyte is observed in a sample,
the Contractor must choose different peaks to quantitate each
multicomponent analyte. A peak common to both analytes present in
the sample must not be used to quantitate either compound.
11.1.2 GC/MS Confirmation of Pesticides and Aroclors
11.1.2.1 Any pesticide or Aroclor analyte listed in Exhibit C for which a
concentration is reported from a GC/EC analysis must have the
identification confirmed by GC/MS if the concentration is
sufficient for that purpose. The following paragraphs are to be
used as guidance in performing GC/MS confirmation. If the
Contractor fails to perform GC/MS confirmation as appropriate, the
D-62/PEST OLM03.0

Agency may require reanalysis of any affected samples at no
additional cost to the Agency.
11.1.2.2 The GC/MS confirmation may be accomplished by one of three general
means:
• Examination of the semivolatile GC/MS library search results
(i.e., TIC data), or
• A second analysis of the semivolatile extract, or
• Analysis of the pesticide/Aroclor extract, following any
solvent exchange and concentration steps that may be
necessary.
11.1.2.3 The semivolatile GC/MS analysis procedures outlined in Exhibit D
SVGA are based on the injection into the instrument of
approximately 20 ng of a target compound in a 2 tiL volume. The
semivolatile CRQL values in Exhibit C are based on the sample
concentration that corresponds to an extract concentration of
10 ng//xL of target analyte. However, these are quantitation
limits, and the detection of analytes and generation of
reproducible mass spectra will routinely be possible at levels 3-
10 times lower. The sample concentration corresponding to
10 ng//xL in extract will depend on the sample matrix.
11.1.2.3.1 For water samples, 20 ng/2 /xL corresponds to a sample
concentration of 10 /xg/L.
11.1.2.3.2 For soil/sediment samples prepared according to the
semivolatile low level soil/sediment method (i.e., 30 g of
soil/sediment), the corresponding sample concentration is
330 /xg/Kg.
11.1.2.3.3 For soil/sediment samples prepared according to the
semivolatile medium level soil/sediment method (i.e., 1 g of
soil/sediment), the corresponding sample concentration is
10,000 /xg/Kg.
11.1.2.3.4 Therefore, based on the values given above, any pesticide
sample in which compound concentration in the sample extract is
greater than or equal to 10 ng//xL for single component
pesticides, 50 ng//xL for Aroclors, and 125 ng/iiL for Toxaphene
should enable the laboratory to confirm the pesticide/Aroclor
by GC/MS analysis of the semivolatile extract.
11.1.2.4 In order to confirm the identification of the target
pesticide/Aroclor, the laboratory must also analyze a reference
standard for the analyte. In order to demonstrate the ability of
the GC/MS system to identify the analyte in question, the
concentration of the standard should be 10 ng/iiL for single
component pesticides, 50 ng//xL for Aroclors, and 125 ng//xL for
Toxaphene.
D-63/PEST OLM03.0
-------
Exhibit D Pesticides/Aroclors — Section 11
Data Analysis and Calculations
Qualitative Identification
11.1.2.5 To facilitate the confirmation of the single component pesticide
analytes from the semivolatile library search data, the laboratory
may wish to include these analytes in the semivolatile continuing
calibration standard at a concentration of 10 ng//iL or less. Do
not include the Aroclors and toxaphene mixture in the semivolatile
initial and continuing calibration standard. If added to this
GC/MS standard, the response factors, retention times, etc. for
these analytes would be reported on the GC/MS quantitation report,
but not on the GC/MS calibration data reporting forms. As only a
single concentration of each analyte would be analyzed, no
linearity (%RSD) or percent difference criteria would be applied
to the response factors for these additional analytes.
11.1.2.6 The laboratory is advised that library search results from the
NIST/EPA/NIH (May 1992 release or later) and Wiley (1991 release
or later) mass spectral library will not likely list the name of
the pesticide/Aroclor analyte as it appears in this SOW, hence,
the mass spectral interpretation specialist is advised to compare
the CAS Registry numbers for the pesticides/Aroclors to those from
the library search routine.
11.1.2."? If the analyte cannot be confirmed from the semivolatile library
search data for the original semivolatile GC/MS analysis, the
laboratory may analyze another aliquot of the semivolatile sample
extract after further concentration of the aliquot. This second
aliquot must either be analyzed as part of a routine semivolatile
GC/MS analysis, including instrument performance checks (DFTPP),
calibration standards containing the pesticides/Aroclors as
described in Section 11.1.2.5, or it must be analyzed along with
separate reference standards for the analytes to be confirmed.
11.1.2.8 If the analyte cannot be confirmed by either the procedures in
Sections 11.1.2.5 or 11.1.2.7, then an aliquot of the extract
prepared for the GC/EC analysis must be analyzed by GC/MS,
following any necessary solvent exchange and concentration steps.
As in Section 11.1.2.%, analysis of a reference standard is
required if the GC/MS continuing calibration standard does not
contain the analyte to be confirmed.
11.1.2.9 Regardless of which of the three approaches above is used for
GC/MS confirmation, the appropriate blank must also be analyzed by
GC/MS to demonstrate that the presence of the analyte was not the
result of laboratory contamination. If the confirmation is based
on the analysis of the semivolatile extract, then the semivolatile
method blank extracted with the sample must also be analyzed. If
the confirmation is based on the analysis of the extract prepared
for the GC/EC analysis, then the pesticide method blank extracted
with the sample must be analyzed.
11.1.2.10 If the identification of the analyte cannot be confirmed by any of
the GC/MS procedures above and the concentration calculated from
the GC/EC analysis is greater than or equal to the concentration
of the reference standard analyzed by GC/MS, then report the

analyte as undetected, adjust the sample quantitation limit (the
value associated with the "U" qualifier) to a sample concentration
equivalent to the concentration of the GC/MS reference standard,
and qualify the results on Form I with one of the laboratory-
defined qualifiers ("X," "Y," or "Z"). In this instance, define
the qualifier explicitly in the SDG Narrative, and describe the
steps taken to confirm the analyte in the SDG Narrative.
11.1.2.11 For GC/MS confirmation of single component analytes, the required
deliverables are copies of the library search results (best TIC
matches) or analyte spectrum and the spectrum of the reference
standard. For multicomponent analytes, spectra of three
characteristic peaks are required for both the sample component
and the reference standard.
11.1.2.12 The purpose of the GC/MS analysis for the single component
pesticides is for identification. The purpose of the GC/MS
analysis for the multicomponent analytes is to confirm the
presence of chlorinated biphenyls in Aroclor and the presence of
chlorinated camphenes in Toxaphene. The GC/MS analytical results
for the pesticides/Aroclors shall not be used for quantitation and
the GC/MS results shall not be reported on Form I and Form X. The
exception noted in Section 11.1.2.10 applies only to analytes that
cannot be confirmed above the reference standard concentration.

j»L most cone, extract used to make dilution
If no dilution is performed, Df = 1.0.
GPC = GPC factor = 2.
11.2.1.2.1 The GPC factor is used to account for the amount of extract
that is not recovered from the mandatory use of GPC cleanup.
Concentrating the extract collected after GPC to 5.0 mL rather
than 10.0 mL for water samples not subjected to GPC maintains
the sensitivity of the soil/sediment method comparable to that
of the water method, but correction of the numerical results is
still required.

11.2.1.2.2 Note that the calibration factors used for the quantitation of
the single component pesticides are the calibration factors
from the midpoint concentration standard in the most recent
initial calibration.
11.2.1.2.3 Because of the likelihood that compounds co-eluting with the
target compounds will cause positive interferences and increase
the concentration determined by the method, the lower of the
two concentrations calculated for each single component
pesticide is reported on Form I. In addition, the
concentrations calculated for both the GC columns are reported
on Form X, along with a percent difference comparing the two
concentrations. The percent difference is calculated according
to Equation 15.

Where,
ConcH = The higher of the two concentrations
for the target compound in question
ConcL = The lower of the two concentrations
for the target compound in question
11.2.1.2.4 Note that using this equation will result in percent difference
values that are always positive. The value will also be
greater than a value calculated using the higher concentration
in the denominator; however, given the likelihood of a positive
interference raising the concentration determined on one GC
column, this is a conservative approach to comparing the two
concentrat ions.
11.2.1.2.5 The quantitative determination of Toxaphene or Aroclors is
somewhat different from that of single component pesticides.
Quantitation of peaks within the detector linear range CRQL to
> 16 times CRQL is based on a single calibration point assuming
linear detector response. Alternatively, a linear calibration
range may be established during a run sequence by a three-point
calibration curve for any multicomponent analyte. If the
concentration is calculated to be 106 times the CRQL, the
Contractor shall contact SMO immediately.
11.2.1.2.6 The quantitation of toxaphene or Aroclors must be accomplished
by comparing the heights or the areas of each of the three to
five major peaks of the multicomponent analyte in the sample
with the calibration factor for the same peaks established
during the initial calibration sequence. The concentration of
multicomponent analytes is calculated by using Equations 13 and
14, where Ax is the area for each of the major peaks of the

multicomponent analyte. The concentration of each peak is
determined and then a mean concentration for the three to five
major peaks is determined on each column.
11.2.1.2.7 The reporting requirements for Toxaphene and the Aroclors are
similar to those for the single component analytes, except that
the lower mean concentration (from three to five peaks) is
reported on Form I, and the two mean concentrations reported on
Form X. The two mean concentrations are compared by
calculating the percent difference using Equation 15.

11.2.3.3 As these limits are only advisory, no further action is required
by the laboratory; however, frequent failures to meet the limits
for surrogate recovery warrant investigation by the laboratory,
and may result in questions from the Agency. Surrogate recovery
data from both GC columns are reported (see Exhibit B).
11.3 Technical Acceptance Criteria for Sample Analysis
The requirements below apply independently ^o each GC column and to all
instruments used for these analyses. Quantstation must be performed on
each GC column.
11.3.1 Samples must be analyzed under the GC/EC operating conditions in
Section 9. The instrument must have met all initial calibration,
calibration verification, and blank technical acceptance criteria.
Samples must be cleaned-up, when required, on a GPC meeting the
technical acceptance criteria for GPC calibration and GPC calibration
checks. Samples must be cleaned-up using florisil meeting the
technical acceptance criteria for florisil. Sample data must be
bracketed at 12-hour intervals (or less) by acceptable analyses of
instrument blanks, PEMs and Individual Standard Mixtures A and B, as
described in Section 10.2.2.1.
11.3.2 The samples must be extracted and analyzed within the contract
required holding times.
11.3.3 The samples must have an associated method blank meeting the
technical acceptance criteria for method blanks. When sulfur cleanup
blanks are required, the samples must have associated with it a
sulfur cleanup blank meeting the technical acceptance criteria for
sulfur cleanup blanks.
11.3.4 The retention time for each of the surrogates must be within the
retention time window as calculated in Section 9 for both GC columns.

Technical Acceptance Criteria for Sample Analysis
11.3.5 No target analyte concentrations may exceed the upper limit of the
initial calibration, or else the extract must be diluted and
reanalyzed.
11.3.6 A standard for any identified multicomponent analyte must be analyzed
during a valid analytical sequence on the same instrument and column,
within 72 hours of its detection in a sample.
11.3.7 The identification of single component pesticides by gas
chromatographic methods is based primarily on retention time data.
The retention time of the apex of a peak can be verified only from an
on-scale chromatogram. The identification of multicomponent analytes
is based primarily on recognition of patterns of retention times
displayed on a chromatogram. Therefore, the following requirements
apply to all data presented for single component and multicomponent
analytes.
11.3.7.1 When no analytes are identified in a sample, the chromatograms
from the analyses of the sample extract must use the same scaling
factor as was used for the low point standard of the initial
calibration associated with those analyses.
11.3.7.2 Chromatograms must display single component pesticides detected in
the sample at less than full scale.
11.3.7.3 Chromatograms must display the largest peak of any multicomponent
analyte detected in the sample at less than full scale.
11.3.7.4 If an extract must be diluted, chromatograms must display single
component pesticides between 10 and 100 percent of full scale.
11.3.7.5 If an extract must be diluted, chromatograms must display the
peaks chosen for quantitation of multicomponent analytes between
25 and 100 percent of full scale.
11.3.7.6 For any sample or blank, the baseline of the chromatogram must
return to below 50 percent of full scale before the elution time
of alpha-BHC, and return to below 25 percent of full scale after
the elution time of alpha-BHC and before the elution time of
decachlorobiphenyl.
11.3.7.7 If a chromatogram is replotted electronically to meet these
requirements, the scaling factor used must be displayed on the
chromatogram.
11.3.7.8 If the chromatogram of any sample needs to be replotted
electronically to meet these requirements, both the initial
chromatogram and the replotted chromatogram must be submitted in
the data package.

11.4 Corrective Action for Sample Analysis
11.4.1 Sample analysis technical acceptance criteria MUST be met before data
are reported. Samples contaminated from laboratory sources or
associated with a contaminated method blank or sulfur cleanup blank
will require re-extraction and reanalysis at no additional cost to
the Agency. Any samples analyzed that do not meet the technical
acceptance criteria will require re-extraction and/or reanalysis at
no additional cost to the Agency.
11.4.2 If the sample analysis technical acceptance criteria are not met,
check calculations, surrogate solutions, and instrument performance.
It may be necessary to recalibrate the instrument or take other
corrective action procedures to meet the technical acceptance
criteria, in which case, the affected samples must be reanalyzed at
no additional cost to the Agency after the corrective action.
11.4.3 The extract from samples which were cleaned-up by GPC using an
automated injection system and have surrogate recoveries outside the
lower advisory surrogate acceptance limits must be checked to assure
that the proper amount was injected on the GPC column. If
insufficient volume was injected, the sample must be reprepared and
reanalyzed at no additional cost to the Agency.
11.4.4 If sample chromatograms have a high baseline or interfering peaks,
inspect the system to determine the cause of the problem (e.g.
carryo er, column bleed, dirty BCD, contaminated gasses, leaking
septum, etc.). After correcting the problem, analyze an instrument
blank to demonstrate that the system is functioning properly.
Reanalyze the sample extracts. If the problem with the samples still
exists, then those samples must be re-extracted and reanalyzed.
Samples which cannot be made to meet the given specifications after
one re-extraction and three-step cleanup (GPC, Florisil, and sulfur
cleanups) are reported in the SDG Narrative and do not require
further analysis.

12.1 Blank Analyses
12.1.1 Introduct ion
There are two types of blanks always required by this method: the
method blank and the instrument blank. A separate sulfur cleanup
blank may be required if all samples associated with a given method
blank are not subjected to sulfur cleanup. Samples that are
associated with a sulfur cleanup blank are also associated with the
method blank with which they were extracted. Both the method and
sulfur cleanup blanks must meet the respective acceptance criteria
for the sample analysis acceptance criteria to be met.
12.1.2 Method Blanks
12.1.2.1 Summary of Method Blanks
A method blank is a volume of a clean reference matrix (reagent
water for water samples, or purified sodium sulfate for
soil/sediment samples) that is carried through the entire
analytical procedure. The volume or weight of the reference
matrix must be approximately equal to the volume or weight of
samples associated with the blank. The purpose of a method blank
is to determine the levels of contamination associated with the
processing and analysis of samples.
12.1.2.2 Frequency of Method Blanks
A method blank must be extracted once for the following, whichever
is most frequent, and analyzed on each GC/EC system used to
analyze samples:
• Each SDG (not to exceed 20 field samples), or
• Each matrix within an SDG, or
• Each extraction procedure within an SDG, or
• Whenever samples are extracted.
12.1.2.3 Procedure for Method Blank Preparation
12.1.2.3.1 For pesticide/Aroclor analyses, a method blank for water
samples consists of a 1 L volume of reagent water spiked with
I mL of the surrogate spiking solution (Section 7.2.4.1). For
soil/sediment samples, the method blank consists of 30 g of
sodium sulfate spiked with 2 mL of the surrogate spiking
solution.

frequency described in Section 12.1.2.2 using the procedure
above and in Section 10 on a GC/EC system meeting the initial
calibration and calibration verification technical acceptance
criteria. Method blanks must undergo cleanup, when required,
on a GPC meeting the technical acceptance criteria for GPC
calibration and GPC calibration checks. Method blanks must be
cleaned-up using Florisil meeting the technical acceptance
criteria for Florisil. Method blanks must be bracketed at 12-
hour intervals (or less) by acceptable analyses of instrument
blanks, PEMS, and individual standard mixtures A and B as
described in Section 10.2.2.1.
12.1.2.4.3 The concentration of the target compounds (Exhibit C
(Pesticides)) in the method blank must be less than the CRQL
for each target compound.
12.1.2.4.4 The method blank must meet all sample technical acceptance
criteria in Sections 11.3.4 to 11.3.7
12.1.2.4.5 Surrogate recoveries must fall within the acceptance windows of
30-150%. In the case of the method blank(s), these limits are
not advisory.
12.1.2.5 Corrective Action for Method Blanks
12.1.2.5.1 If a method blank does not meet the technical acceptance
criteria, the Contractor must consider the system to be out of
control.
12.1.2.5.2 If contamination is a problem, then the source of the
contamination must be investigated and appropriate corrective
measures must be taken and documented before further sample
analysis proceeds. It is the Contractor's responsibility to
ensure that method interferences caused by contaminants in
solvents, reagents, glassware, and sample storage and sample
processing hardware that lead to discrete artifacts and/or
elevated baselines be investigated and appropriate corrective
actions be taken and documented before further sample analysis.
All samples associated with a contaminated method blank must be
re-extracted/reanalyzed at no additional cost to the Agency.
12.1.2.5.3 If the surrogate recoveries in the method blank do not meet the
acceptance criteria listed in 12.1.2.4.5, first reanalzye the
method blank. If surrogate recoveries do not meet the

acceptance criteria after reanalysis, the method blank and all
samples associated with that method blank must be re-extracted
and reanalyzed at no additional cost to the Agency.
12.1.2.5.4 If the method blank failed to meet the criteria listed in
Sections 12.1.2.4.2 and 12.1.2.4.4, then there is an instrument
problem. Correct the instrument problem and reanalyze the
method blank.
12.1.3 Sulfur Cleanup Blanks
12.1.3.1 Summary of Sulfur Cleanup Blanks
The sulfur cleanup blank is a modified form of the method blank.
The sulfur cleanup blank is hexane spiked with the surrogates and
carried through the sulfur cleanup and analysis procedures. The
purpose of the sulfur cleanup blank is to determine the levels of
contamination associated with the separate sulfur cleanup steps.
12.1.3.2 Frequency of Sulfur Cleanup Blanks
The sulfur cleanup blank is prepared separately when only part of
a set of samples extracted together requires sulfur removal. A
method blank is associated with the entire set of samples. The
sulfur cleanup blank is associated with the part of the set which
required sulfur cleanup. If all the samples associated with a
given method blank are subjected to sulfur cleanup, then the
method blank must be subjected to sulfur cleanup, and no separate
sulfur cleanup blank is required.
12.1.3.3 Procedure for Sulfur Cleanup Blank
12.1.3.3.1 The concentrated volume of the blank must be the same as the
final volume of the samples associated with the blank. The
sulfur blank must also contain the surrogates at the same
concentrations as the sample extracts (assuming 100.0 percent
recovery). Therefore, add 0.1 mL of the surrogate solution to
0.9 mL of hexane in a clean vial, or for a sulfur blank with a
final volume of 2 mL, add 0.2 mL of the surrogate solution to
1.8 mL of hexane in a clean vial.
12.1.3.3.2 Proceed with the sulfur removal (Section 10.1.8.3.3.1 or
10.1.8.3.3.2) using the same technique (mercury or copper) as
the samples associated with the blank.
12.1.3.3.3 Analyze the sulfur cleanup blank according to Section 10.2.
Assuming that the material in the sulfur cleanup blank resulted
from the extraction of a 1 L water sample, calculate the
concentration of each analyte using the equation in Section
11.2.1.1. Compare the results to the CRQL values for water
samples in Exhibit C (Pesticides).

Correct the instrument problem and reanalyze the sulfur cleanup
blank.
12.1.4 Instrument Blanks
12.1.4.1 Summary of Instrument Blanks
An instrument blank is a volume of clean solvent spiked with the
surrogates and analyzed on each GC column and instrument used for
sample analysis. The purpose of the instrument blank is to
determine the levels of contamination associated with the
instrumental analysis itself, particularly with regard to the
carry over of analytes from standards or highly contaminated
samples into other analyses.
12.1.4.2 Frequency of Instrument Blanks
The first analysis in a 12-hour analysis sequence must be an
instrument blank. All acceptable sample analyses are to be
bracketed by acceptable instrument blanks, as described in Section
10.2.2.1 If more than 12 hours have elapse 1 since the injection
of t le instrument blank that bracketed a previous 12-hour period,
an instrument blank must be analyzed to initiate a new 12-hour
sequence.
12.1.4.3 Procedure for Instrument Blanks
12.1.4.3.1 Prepare the instrument blank by spiking the surrogates into
hexane or iso-octane for a concentration of 20 ng/mL of
tetrachloro-m-xylene and decachlorobiphenyl.
12.1.4.3.2 Analyze the instrument blank according to Section 10.2 at the
frequency listed in Section 12.1.4.2
12.1.4.3.3 For comparing the results of the instrument blank analysis to
the CRQLs, assume that the material in the instrument resulted
from the extraction of a 1 L water sample and calculate the
concentration of each analyte using the equation in Section

12.2 Matrix Spike/Matrix Spike Duplicate (MS/MSD)
12.2.1 Summary of MS/MSD
In order to evaluate the effects of the sample matrix on the methods
used for pesticide/Aroclor analyses, the Agency has prescribed a
mixture of pesticide/Aroclor target compounds to be spiked into two
aliquots of a sample, and analyzed in accordance with the appropriate
method.
12.2.2 Frequency of MS/MSD Analysis
12.2.2.1 A matrix spike and matrix spike duplicate must be extracted and
analyzed at least every 20 samples of each matrix. NOTE: There
is no differentiation between "low" and "medium" level
soil/sediment samples in this method. Therefore only one
soil/sediment MS/MSD is to be submitted per Sample Delivery Group
(SDG).
12.2.2.2 As part of the Agency's QA/QC program, water rinsate samples
and/or field blanks may be delivered to a laboratory for analysis.
Do not perform MS/MSD analysis on a water rinsate sample or field
blank.
12.2.2.3 If the EPA Region designates a sample to be used as an MS/MSD,
then that sample must be used. If there is insufficient sample
volume remaining to perform an MS/MSD, then the Contractor shall
choose another sample to perform an MS/MSD analysis. At the time
the selection is made, the Contractor shall notify the Region
(through SMO) that insufficient sample was received and identify
the EPA sample selected for the MS/MSD analysis. The rationale
for the choice of another sample other than the one designated by
the Agency shall be documented in the SDG Narrative.
12.2.2.4 If there is insufficient sample volume remaining in any of the
samples in an SDG to perform an MS/MSD, the Contractor shall
immediately contact SMO to inform them of the problem. SMO will
contact the Region for instructions. The Region will either
approve that no MS/MSD be performed, or require that a reduced
sample aliquot be used for the MS/MSD analysis. SMO will notify
the Contractor of the Region's decision. The Contractor shall
document the decision in the SDG Narrative.
12.2.2.5 The Contractor will not be paid for MS/MSD analysis performed at a
greater frequency then required by the contract. If it appears
that the Region has requested MS/MSD analysis at a greater
frequency then required by the contract, the Contractor shall
contact SMO. SMO will contact the Region to determine which
samples should have an MS/MSD performed on them. SMO will notify
the Contractor of the Region's decision. The Contractor shall
document the decision in the SDG Narrative.

12.2.2.6 When a Contractor receives only performance evaluation (PE)
samples, no MS/MSD shall be performed within that SDG.
12.2.2.7 When a Contractor receives a PE sample as part of a larger SDG, a
sample other than the PE sample must be chosen for the MS/MSD when
the Region did not designate samples to be used for this purpose.
If the PE sample is received as an ampulated standard extract, the
ampulated PE sample is not considered to be another matrix type.
12.2.3 Procedure for Preparing MS/MSD
12.2.3.1 Water Samples
For water samples, measure out two additional 1 L aliquots of the
sample chosen for spiking. Adjust the pH of the samples (if
required) and fortify each with 1 mL of matrix spiking solution.
Using a syringe or volumetric pipet, add 1 mL of surrogate spiking
solution to each sample. Extract, concentrate, cleanup, and
analyze matrix spikes and matrix spike duplicate according to
Section 10.0.
12.2.3.2 Soil/Sediment Samples
For soil/sediment samples weigh out two additional 30 g (record
weight to the nearest 0.1 g) aliguots of the sample chosen for
spiking. Add 1 mL of matrix ppiking solution and 2 mL of
surrogate solution. Extract, concentrate, cleanup, and analyze
matrix spikes and matrix spike duplicates according to Section
10.0.
12.2.3.3 Note: Before any MS/MSD analysis, analyze the original sample,
then analyze the MS/MSD at the same concentration as the most
concentrated extract for which the original sample results will be
reported. For example, if the original sample is to be reported
at a 1:1 dilution and a 1:10 dilution, then analyze and report the
MS/MSD at a 1:1 dilution only. However, if the original sample is
to be reported at a 1:10 dilution and a 1:100 dilution, then the
MS/MSD must be analyzed and reported at a 1:10 dilution only. Do
not further dilute the MS/MSD samples to get either spiked or non-
spiked analytes within calibration range.
12.2.4 Calculations for MS/MSD
12.2.4.1 The percent recoveries and the relative percent difference between
the recoveries of each of the compounds in the matrix spike
samples will be calculated and reported by using the following
equations:

14.0 POLLUTION PREVENTION
14.1 Pollution prevention encompasses any technique that reduces or
eliminates the quantity or toxicity of waste at the point of generation.
Numerous opportunities for pollution prevention exist in laboratory
operation. The EPA has established a preferred hierarchy of
environmental management techniques that places pollution prevention as
the management option of first choice. Whenever feasible, laboratory
personnel should use pollution prevention techniques to address their
waste generation. When wastes cannot be feasibly reduced at the source,
the Agency recommends recycling as the next best option.
14.2 For information about pollution prevention that may be applicable to
laboratories and research institutions, consult Less is Better:
Laboratory Chemical Management for Waste Reduction, available from the
American Chemical Society's Department of Government Relations and
Science Policy, 1155 16th Street N.W., Washington, D.C. 20036, (202)872-
4477.
15.0 WASTE MANAGEMENT
The Environmental Protection Agency requires that laboratory waste
management practices be conducted consistent with all applicable rules
and regulations. The Agency urges laboratories to protect the air,
water, and land by minimizing and controlling all releases from hoods
and bench operations, complying with the letter and spirit of any sewer
discharge permits and regulations, and by complying with all solid and
hazardous waste regulations, particularly the hazardous waste
identification rules and land disposal restrictions. For further
information on waste management consult The Waste Management Manual for
Laboratory Personnel, available from the American Chemical Society at
the address listed in Section 14.2.

Overview
1.0 OVERVIEW
1.1 Quality assurance and quality control are integral parts of the
Environmental Protection Agency's (EPA) Contract Laboratory Program
(CLP). The quality assurance (QA) process consists of management review
and oversight at the planning, implementation, and completion stages of
the environmental data collection activity, and ensures that data
provided are of the quality required. The quality control (QC) process
includes those activities required during data collection to produce the
data quality desired and to document the quality of the collected data.
1.2 During the planning of an environmental data collection program, QA
activities focus on defining data quality criteria and designing a QC
system to measure the quality of data being generated. During the
implementation of the data collection effort, QA activities ensure that
the QC system is functioning effectively, and that the deficiencies
uncovered by the QC system are corrected. After environmental data are
collected, QA activities focus on assessing the quality of data obtained
to determine its suitability to support enforcement or remedial
decisions.
1.3 This exhibit describes the overall quality assurance/quality control
operations and the processes by which the CLP meets the QA/QC objectives
defined above. This contract requires a variety of QA/QC activities.
These contract requirements are the minimum QC operations necessary to
satisfy the analytical requirements associated with the determination of
the different method analytes. These QC operations are designed to
facilitate laboratory comparison by providing EPA with comparable data
from all Contractors. These requirements do not release the analytical
Contractor from maintaining their own QC checks on method and instrument
performance.
E-4 OLM03.0

Exhibit E — Section 2
Introduction
2.0 INTRODUCTION
2.1 Appropriate use of data generated under the large range of analytical
conditions encountered in environmental analyses requires reliance on
the QC procedures and criteria incorporated into the methods. The
••nethods in this contract have been validated on samples typical of those
received by the laboratories in the CLP. However, the validation of
these methods does not guarantee that they perform equally well for all
sample matrices encountered. Inaccuracies can also result from causes
other than unanticipated matrix effects, such as sampling artifacts,
equipment malfunctions, and operator error. Therefore, the quality
control component of each method is indispensable.
2.2 The data acquired from QC procedures are used to estimate and evaluate
the information content of analytical results and to determine the
necessity for or the effect of corrective action procedures. The
parameters used to estimate information content include precision,
accuracy, detection limit, and other quantitative and qualitative
indicators. In addition, QC procedures give an overview of the
activities required in an integrated program to generate data of known
and documented quality required to meet defined objectives.
2.3 The necessary components of a complete QA/QC program include internal QC
criteria that demonstrate acceptable levels of performance, as
determined by QA review. External review of data and procedures is
accomplished by the monitoring activities of the National Program
Of-ice, Regional data users, Sample Management Oifice (SMO), and
Environme-.tal Monitoring Systems Laboratory/Las Vegas (EMSL/LV). Each
external review accomplishes a different purpose. These reviews are
described in specific sections of this exhibit. Laboratory evaluation
samples, GC/MS tape audits, and data packages provide an external QA
reference for the program. A Contractor on-site evaluation system is
also part of the external QA monitoring. A feedback loop provides the
results of the various review functions to the Contractors through
direct communications with the Technical Project Officers (TPOs) and
Administrative Project Officers (APOs).
2.4 This exhibit does not provide specific instructions for constructing QA
plans, QC systems, or a QA organization. It is, however, an explanation
of the QA/QC requirements of the program. It outlines some minimum
standards for QA/QC programs. It also includes specific items that are
required in a QA plan and by the QA/QC documentation detailed in this
contract. Delivery of this documentation provides the Agency with a
complete data package which will stand alone, and limits the need for
contact with the Contractor or with an analyst, at a later date, if some
aspect of the analysis is questioned.
2.5 In order to assure that the product delivered by the Contractor meets
the requirements of the contract, and to improve interlaboratory data
comparison, the Agency requires the following from the Contractor:
• Preparation of and adherence to a written quality assurance plan,
the elements of which are designated in Section 3,
E-5 OLM03.0
-------
Exhibit E — Section 2
Introduction
• Preparation of and adherence to QA/QC standard operating procedures
as described in Section 4,
• Adherence to the analytical methods and associated QC requirements
specified in the contract,
• Verification of analytical standards and documentation of the purity
of neat materials and the purity and accuracy of solutions obtained
from private chemical supply houses,
• Submission of all raw data and pertinent documentation for Regional
review,
• Participation in the analysis of laboratory evaluation samples,
including adherence to corrective action procedures,
• Submission, upon request, of GC/MS tapes and applicable
documentation for tape audits, including a copy of the sample data
package,
• Participation in on-site laboratory evaluations, including adherence
to corrective action procedures, and
• Submission of all original documentation generated during sample
analyses for Agency review.

Standard Operating Procedures
4.0 STANDARD OPERATING PROCEDURES
4.1 Introduction. In order to obtain reliable results, adherence to
prescribed analytical methodology is imperative. In any operation that
is performed on a repetitive basis, reproducibility is best accomplished
through the use of standard operating procedures (SOPs). As defined by
EPA, an SOP is a written document which provides directions for the
step-by-step execution of an operation, analysis, or action which is
commonly accepted as the method for performing certain routine or
repetitive tasks.
4.1.1 SOPs prepared by the Contractor shall be functional (i.e., clear,
comprehensive, up-to-date, and sufficiently detailed to permit
duplication of results by qualified analysts). The SOPs shall be
paginated consecutively in ascending order.
4.1.2 All SOPs shall reflect activities as they are currently performed by
the Contractor. In addition, all SOPs shall be:
• Consistent with current Agency regulations, guidelines, and the
CLP contract's requirements.
• Consistent with instrument manufacturers' specific instruction
manuals.
• Available to the Agency during an on-site laboratory evaluation.
A complete set of SOPs shall be bound together and available for
inspection at such evaluations. During on-site evaluations,
Contractor personnel may be asked to demonstrate the application
of the SOPs.
• Available to the designated recipients within 7 days, upon
request by the Technical Project Officer or Administrative
Project Officer.
• Capable of providing for the development of documentation that is
sufficiently complete to record the performance of all tasks
required by the protocol.
• Capable of demonstrating the validity of data reporteU by the
Contractor and explaining the cause of missing or inconsistent
results.

Analytical Standards Requirements
5.0 ANALYTICAL STANDARDS REQUIREMENTS
5.1 Overview. EPA will not supply analytical reference standards either for
direct analytical measurements or for the purpose of traceability. All
Contractors shall be required to prepare from neat materials or purchase
from private chemical supply houses those standards necessary to
successfully and accurately perform the analyses required in this
protocol.
5.2 Preparation of Chemical Standards from the Neat High Purity Bulk
Material. A Contractor may prepare their chemical standards from neat
materials. Contractors shall obtain the highest purity possible when
purchasing neat chemical standards; when standards are purchased at less
than 97% purity, the Contractor shall document the reason why a higher
purity could not be obtained.
5.2.1 Neat chemical standards shall be kept refrigerated when not being
used in the preparation of standard solutions. Proper storage of
neat chemicals is essential in order to safeguard them from
decomposition.
5.2.2 The purity of a compound can sometimes be misrepresented by a
chemical supply house. Since knowledge of purity is needed to
calculate the concentration of solute in a solution standard, it is
the Contractor's responsibility to have analytical documentation
ascertaining that the purity of each compound is correctly stated.
Purity confirmation, when performed, should use either differential
scanning calorimetry, gas chromatography with flame ionization
detection, high performance liquid chromatography, infrared
spectrometry, or other appropriate techniques. Use of two or more
independent methods is recommended. The correction factor for
impurity when weighing neat materials in the preparation of solution
standards is:
EQ. 1
weight of impure compound = ^ight of pure compound
(percent purity/100)
where "weight of pure compound" is that required to prepare a
specific volume of a standard solution at a specified concentration,
5.2.3 When compound purity is assayed to be 97% or greater, the weight may
be used without correction to calculate the concentration of the
stock standard. If the compound purity is assayed to be less than
97%, the weight shall be corrected when calculating the concentration
of the stock solution.

Exhibit E — Section 5
Analytical Standards Requirements
5.2.4 Mis-identification of compounds occasionally occurs and it is
possible that a mislabeled compound may be received from a chemical
supply house. It is the Contractor's responsibility to have
analytical documentation ascertaining that all compounds used in the
preparation of solution standards are correctly identified.
Identification confirmation, when performed, shall use gas
chromatography/mass spectrometry analysis on at least two different
analytical columns, or other appropriate techniques.
5.2.5 Calculate the weight of material to be weighed out for a specified
volume taking into account the purity of the compound and the desired
concentration. A second person shall verify the accuracy of the
calculations. Check balances for accuracy with a set of standard
weights every 12 hours. All weighing shall be performed on an
analytical balance to the nearest 0.1 mg and verified by a second
person. The solvent used to dissolve the solute shall be compatible
with the protocol in which the standard is to be used; the solute
shall be soluble, stable, and nonreactive with the solvent. In the
case of a multicomponent solution, the components must not react with
each other.
5.2.6 Transfer the solute to a volumetric flask and dilute to the specified
solution volume with solvent after ensuring dissolution of the solute
in the solvent. Sonication or warming may be performed to promote
dissolution of the solute. This solution shall be called the primary
standard and all subsequent dilutions shall be traceable back to the
primary standard.
5.2.7 Log notebooks shall be kept for all weighing and dilutions. All
subsequent dilutions from the primary standard and the calculations
for determining their concentrations shall be recorded and verified
by a second person. All solution standards shall be refrigerated
when not in use. All solution standards shall be clearly labeled as
to the identity of the compound or compounds, concentration, date
prepared, solvent, and initials of the preparer.
5.3 Purchase of Chemical Standards Already in Solution. Solutions of
analytical reference standards can be purchased by Contractors provided
they meet the following criteria.
5.3.1 Contractors shall maintain the following documentation to verify the
integrity of the standard solutions they purchase:
• Mass spectral identification confirmation of the solution,
• Purity confirmation of the solution, and
• Chromatographic and quantitative documentation that the solution
standard was QC checked according to the following section.
5.3.2 The Contractor shall purchase standards for which the quality is
demonstrated statistically and analytically. One way this may be
demonstrated is to prepare and analyze three solutions, a high
standard, a low standard, and a standard at the target concentration
E-19 OLM03.0

Exhibit E — Section 5
Analytical Standards Requirements
(see Sections 5.3.2.1 and 5.3.2.2). The Contractor shall have
documentation to demonstrate that the analytical results for the high
standard and low standard are consistent with the difference in
theoretical concentrations. This is done by the Student's t-test in
Section 5.3.2.4. If this is achieved, the Contractor shall then
demonstrate that the concentration of the target standard lies midway
between the concentrations of the low and high standards. This is
done by the Student's t-test in Section 5.3.2.5. The standard is
certified to be within 10% of the target concentration using the
equations in Section 5.3.2.6. If this procedure is used, the
Contractor shall document that the following have been achieved.
5.3.2.1 Two solutions of identical concentration shall be prepared
independently from solutions. An aliquot of the first solution
shall be diluted to the intended concentration (the "target
standard"). One aliquot is taken from the second solution and
diluted to a concentration 10% greater than the target standard.
This is called the "high standard." One further aliquot is taken
from the second solution and diluted to a concentration 10% less
that the target standard. This is called the "low standard."
5.3.2.2 Six replicate analyses of each standard (a total of 18 analyses)
shall be performed in the following sequence: low standard,
target, high standard, low standard, target standard, high
standard, ...
5.3.2.3 The mean and variance of the six results for each solution shall
be calculated.

ability to discriminate the 10% difference in concentrations
has not been demonstrated. In such a case, the standards are
not acceptable.
5.3.2.6.2 In any event, the Contractor is responsible for the quality of
the standards employed for analyses under this contract.
5.4 Requesting Standards From the EPA Standards Repository. Solutions of
analytical reference materials can be ordered from the U.S. EPA Chemical
Standards Repository, depending on availability. The Contractor can
place an order for standards only after demonstrating that these
standards are not available from commercial vendors, either in solution
or as a neat material.
5.5 Documentation of the Verification and Preparation of Chemical Standards.
It is the responsibility of each Contractor to maintain the necessary
documentation to show that the chemical standards they have used in the
performance of CLP analysis conform to the requirements previously
listed.
5.5.1 Weighing logbooks, calculations, chromatograms, mass spectra, etc.,
whether produced by the Contractor or purchased from chemical supply
houses, shall be maintained by the Contractor and may be subject to
review during on-site laboratory evaluations. In those cases where
the documentation is supportive of the analytical results of data
packages sent to the Agency, such documentation is to be kept on file
by the Contractor for a period of one year.
5.5.2 Upon request by the Technical Project Officer or Administrative
Project Officer, the Contractor shall submit their most recent
previous year's documentation (12 months) for the verification and
preparation of chemical standards within 14 days of the receipt of

Contract Compliance Screening
6.0 CONTRACT COMPLIANCE SCREENING
6.1 Contract compliance screening (CCS) is one aspect of the Government's
contractual right of inspection of analytical data. CCS examines the
Contractor's adherence to the contract requirements based on the sample
data package delivered to the Agency.
6.2 CCS is performed by the Sample Management Office (SMO) under the
direction of the Agency. To assure a uniform review, a set of
standardized procedures has been developed to evaluate the sample data
package submitted by a Contractor against the technical and completeness
requirements of the contract. The government reserves the right to add
and/or delete individual checks. CCS results are used in conjunction
with other information to measure overall Contractor performance and to
take appropriate actions to correct deficiencies in performance.
6.3 CCS results are mailed to the Contractor and all other data recipients.
The Contractor has a period of time to correct deficiencies. The
Contractor shall send all corrections to the Regional client and SMO.
6.4 The Agency may generate a CCS trend report which summarizes CCS results
over a given period of time. The Agency may send the CCS trend report
or discuss the CCS trend report during an on-site laboratory evaluation.
In a detailed letter to the Technical Project Officer and Administrative
Project Officer, the Contractor shall address the deficiencies and the
subsequent corrective action implemented by the Contractor to correct
the deficiencies within 14 days of receipt of the report or the on-site
laboratory evaluation. An alternate delivery schedule may be proposed
by the Contractor, but it is the sole decision of the Agency,
represented by the Technical Project Officer or Administrative Project
Officer, to approve or disapprove the alternate delivery schedule. If
an alternate delivery schedule is proposed, the Contractor shall
describe in a letter to the Technical Project Officer, Administrative
Project Officer, and Contracting Officer why he/she is unable to meet
the delivery schedule listed in this section. The Technical Project
Officer/Administrative Project Officer will not grant an extension for
greater than 14 days for the Contractor's response to the CCS trend
report. The Contractor shall proceed and not assume that an extension
will be granted until so notified by the Technical Project Officer
and/or Administrative Project Officer.
6.5 If new SOPs are required to be written or SOPs are required to be
amended because of the deficiencies and the subsequent corrective action
implemented by the Contractor, the Contractor shall write/amend and
submit the SOPs per the requirements listed in Section 4.
6.6 If the Contractor fails to adhere to the requirements listed in Section
6, the Contractor may expect, but the Agency is not limited to, the
following actions: reduction of number of samples sent under the

Regional Data Review
7.0 REGIONAL DATA REVIEW
7.1 Contractor data are generated to meet the specific needs of the EPA
Regions. In order to verify the usability of data for the intended
purpose, each Region reviews data from the perspective of the end user,
based upon functional aspects of data quality. General guidelines for
data review have been developed jointly by the Regions and the National
Program Office. Each Region uses these guidelines as the basis for data
evaluation. Individual Regions may augment the basic guideline review
process with additional review based on Region-specific or site-specific
concerns. Regional reviews, like the sites under investigation, vary
based on the nature of the problems under investigation and the Regional
response appropriate to the specific circumstances.
7.2 Regional data reviews, relating usability of the data to a specific
site, are part of the collective assessment process. They complement
the review done at the Sample Management Office, which is designed to
identify contractual discrepancies, and the review done at EMSL/LV,
which is designed to evaluate Contractor and method performance. These
individual evaluations are integrated into a collective review that is
necessary for Program and Contractor administration and management and
may be used to take appropriate action to correct deficiencies in the
Contractor's performance.

Laboratory Evaluation Samples
8.0 LABORATORY EVALUATION SAMPLES
8.1 Although intralaboratory QC may demonstrate contractor and method
performance that may be tracked over time, an external performance
evaluation program is an essential feature of a QA program. As a means
of measuring Contractor and method performance, Contractors participate
in interlaboratory comparison studies conducted by the Agency. Results
from the analysis of these laboratory evaluation samples, also referred
to as performance evaluation (PE) samples, will be used by the Agency to
verify the Contractor's continuing ability to produce acceptable
analytical data. The results are also used to assess the precision and
accuracy of the analytical methods for specific analytes.
8.2 Sample sets may be provided to participating Contractors as frequently
as on an SDG-by-SDG basis as a recognizable QC sample of known
composition, as a recognizable QC sample of unknown composition, or not
recognizable as a QC material. The laboratory evaluation samples may be
sent either by the Regional client or the National Program Office. The
results of all such quality control samples may be used as the basis for
an equitable adjustment to reflect the reduced value to the Agency; may
be used as the basis for rejection of data for: sample(s) within an SDG,
a fraction within an SDG or the entire SDG; and/or may be used as the
basis for contract action. The Contractor shall analyze the samples and
return the data package and all raw data within the contract required
turnaround time.
8.3 At a minir-im, the results are evaluated fo^- compound identification,
quantitation, and sample contamination. Confidence intervals for the
quantitation of target compounds are based on reported values using
population statistics. The Agency may adjust the scores on any given
laboratory evaluation sample to compensate for unanticipated
difficulties with a particular sample. Normally, a fraction of the
compounds spiked into the sample are not specifically listed in the
contract. Contractors are required to use the NIST/EPA/NTH (May 1992
release or later) and/or Wiley (1991 release or later), or equivalent,
mass spectral library to tentatively identify a maximum number of non-
target compounds in each fraction that are present above a minimal
response. Tentative identification of these compounds, based on
contractually described spectral interpretation procedures, is evaluated
and integrated into the evaluation process.
8.4 A Contractor's results on the laboratory evaluation samples will
determine the Contractor's performance as follows.
8.4.1 Acceptable, No Response Required (Score greater than or equal to
90%): Data meets most or all of the scoring criteria.
8.4.2 Acceptable, Response Explaining Deficiency(ies) Required (Score
greater than or equal to 75% but less than 90%): Deficiencies exist
in the Contractor's performance.
8.4.3 Unacceptable Performance, Response Explaining Deficiency(ies)
Required (Score less than 75%): Deficiencies exist in the
Contractor's performance to the extent that the National Program

Office has determined that the Contractor has not demonstrated the
capability to meet the contract requirements.
8.5 In the case of Sections 8.4.2 and 8.4.3, the Contractor shall describe
the deficiency(ies) and the action(s) taken to correct the
deficiency(ies) in a letter to the Administrative Project Officer, the
Technical Project Officer and EMSL/LV within 14 days of receipt of
notification from the Agency.
8.6 An alternate delivery schedule may be proposed by the Contractor, but it
is the sole decision of the Agency, represented either by the Technical
Project Officer or Administrative Project Officer, to approve or
disapprove the alternate delivery schedule. If an alternate delivery
schedule is proposed, the Contractor shall describe in a letter to the
Technical Project Officer, Administrative Project Officer, and the
Contracting Officer why he/she is unable to meet the delivery schedule
listed in this section. The Technical Project Officer/Administrative
Project Officer will not grant an extension for greater than 14 days for
the Contractor's response letter to the laboratory evaluation sample
report. The Contractor shall proceed and not assume that an extension
will be granted until so notified by the Technical Project Officer
and/or Administrative Project Officer.
8.7 If new SOPs are required to be written or SOPs are required to be
amended because of the deficiencies and the subsequent corrective action
implemented by the Contractor, the Contractor shall write/amend and
submit the SOPs per the requirements listed in Section 4.
8.8 The Contractor shall be notified by the Technical Project Officer,
Administrative Project Officer, or Contracting Officer concerning the
remedy for their unacceptable performance. The Contractor may expect,
but the Agency is not limited to, the following actions: reduction of
the number of samples sent under the contract, suspension of sample
shipment to the Contractor, a GC/MS tape audit, a data package audit, an
on-site laboratory evaluation, a remedial laboratory evaluation sample,
and/or contract sanctions, such as a Cure Notice.
NOTE: The Contractor's prompt response demonstrating that corrective
actions have been taken to ensure the Contractor's capability to meet
contract requirements may facilitate continuation of sample scheduling.
8.9 If the Contractor fails to adhere to the requirements listed in Section
8, the Contractor may expect, but the Agency is not limited to, the
following actions: reduction in the number of samples sent under the
contract, suspension of sample shipment to the Contractor, a GC/MS tape
audit, a data package audit, an on-site laboratory evaluation, a
remedial laboratory evaluation sample and/or contract sanctions, such as

GC/MS Tape Audits
9.0 GC/MS TAPE AUDITS
9.1 Overview. Periodically, the Agency requests the GC/MS magnetic tapes
from Contractors for a specific Case in order to accomplish tape audits.
Generally, tape submissions and audits are requested for the following
reasons.
• Program overview,
• Indication of data quality problems from EMSL/LV, SMO, or Regional
data reviews,
• Support for on-site audits, and
• Specific Regional requests.
9.1.1 Depending upon the reason for an audit, the tapes from a recent Case,
a specific Case, or a laboratory evaluation sample may be requested.
Tape audits provide a mechanism to assess adherence to contractual
requirements and to ensure the consistency of data reported on the
hardcopy/floppy diskettes with that generated on the GC/MS tapes.
This function provides external monitoring of Program QC requirements
and checks adherence of the Contractor to internal QA procedures. In

Data Package Audits
10.0 DATA PACKAGE AUDITS
10.1 Overview. Data package audits are performed by the Agency for program
overview and specific Regional concerns and to assess the technical
quality of the data and evaluate overall Contractor performance. They
provide the Agency with an in-depth inspection and evaluation of the
Case data package with regard to achieving QA/QC acceptability. Data
packages are periodically selected from recently received Cases. They
are evaluated for the technical quality of hardcopy raw data, quality
assurance, and adherence to contractual requirements. A thorough review
of the raw data is completed, including: a check of instrument
printouts, quantitation reports, chromatograms, spectra, library
searches and other documentation for deviations from the contractual
requirements, a check for transcription and calculation errors, a review
of the qualifications of the Contractor personnel involved with the
Case, and a review of all current SOPs on file. Standardized procedures
have been established to assure uniformity of the auditing process.
10.2 Responding to the Data Package Audit Report. After completing the data
package audit, the Agency may send a. copy of the data package audit
report to the Contractor or may discuss the data package audit report at
an on-site laboratory evaluation. In a detailed letter to the Technical
Project Officer, Administrative Project Officer, and EMSL/LV, the
Contractor shall discuss the corrective actions implemented to resolve
the deficiencies listed in the data package audit report within 14 days
of receipt of the report.
10.2.1 An alternate delivery schedule may be proposed by the Contractor, but
it is the sole decision of the Agency, represented either by the

On-Site Laboratory Evaluations
11.0 ON-SITE LABORATORY EVALUATIONS
11.1 Overview. At a frequency dictated by a Contractor's performance, the
Administrative Project Officer, Technical Project Officer or the
Contracting Officer will conduct an on-site laboratory evaluation. On-
site laboratory evaluations are Carried out to monitor the Contractor's
ability to meet selected terms and conditions specified in the contract.
The evaluation process incorporates two separate categories: a quality
assurance evaluation and an evidentiary audit.
11.2 Quality Assurance On-Site Evaluation. Quality assurance evaluators
inspect the Contractor's facilities to verify the adequacy and
maintenance of instrumentation, the continuity of personnel meeting
experience or education requirements, and the acceptable performance of
analytical and QC procedures.
11.2.1 The Contractor shall expect that items to be monitored will include,
but not be limited to, the following items:
• Size and appearance of the facility,
• Quantity, age, availability, scheduled maintenance and
performance of instrumentation,
• Availability, appropriateness, and utilization of the QAP and
SOPs,
• Staff qualifications and experience, and personnel training
programs,
• Reagents, standards, and sample storage facilities,
• Standard preparation logbooks and raw data,
• Bench sheets and analytical logbook maintenance and review, and
• Review of the Contractor's sample analysis/data package
inspection/data management procedures.
11.2.2 Prior to an on-site evaluation, various documentation pertaining to
performance of the specific Contractor is integrated in a profile
package for discussion during the evaluation. Items that may be
included are previous on-site reports, laboratory evaluation sample
scores, Regional review of data, Regional QA materials, GC/MS tape
audit reports, data audit reports, results of CCS, and date trend
reports.
11.3 Evidentiary Audit. Evidence auditors conduct an on-site laboratory
evaluation to determine if Contractor policies and procedures are in
place to satisfy evidence handling requirements as stated in Exhibit F.
The evidence audit comprises a procedural audit, an audit of written
SOPs, and an audit of analytical project file documentation.
E-33 OLM03.0

On-Site Laboratory Evaluations
11.3.1 Procedural Audit. The procedural audit consists of review and
examination of actual standard operating procedures and accompanying
documentation for the following Contractor operations: sample
receiving, sample storage, sample identification, sample security,
sample tracking (from receipt to completion of analysis) and
analytical project file organization and assembly.
11.3.2 Written SOPs Audit. The written SOPs audit consists of review and
examination of the written SOPs to determine if they are accurate and
complete for the following Contractor operations: sample receiving,
sample storage, sample identification, sample security, sample
tracking (from receipt to completion of analysis) and analytical
project file organization and assembly.
11.3.3 Analytical Project File Evidence Audit. The analytical project file
evidence audit consists of review and examination of the analytical
project file documentation. The auditors review the files to
determine:
• The accuracy of the document inventory,
• The completeness of the file,
• The adequacy and accuracy of the document numbering system,
• Traceability of sample activity,
• Identification of activity recorded on the documents, and
• Error correction methods.
11.4 Discussion of the On-Site Team's Findings. During the debriefing, the
auditors present their findings and recommendations for corrective
actions necessary to the Contractor personnel.
11.5 Corrective Action Reports for Follow-Through to Quality Assurance and
Evidentiary Audit Reports. Following an on-site laboratory evaluation,
quality assurance and/or evidentiary audit reports which discuss
deficiencies found during the on-site evaluation may be sent to the
Contractor. In a detailed letter, the Contractor shall discuss the
corrective actions implemented to resolve the deficiencies discussed
during the on-site evaluation and discussed in the report(s) to the
Technical Project Officer, Administrative Project Officer, and EMSL/LV
within 14 days of receipt of the report.

Quality Assurance and Data Trend Analysis
12.0 QUALITY ASSURANCE AND DATA TREND ANALYSIS
12.1 Data submitted by Contractors are subject to review from several
aspects: compliance with contract-required QC, usability, and full data
package evaluation. Problems resulting from any of these reviews may
determine the need for a GC/MS tape audit, an on-site laboratory
evaluation and/or a remedial laboratory evaluation sample. In addition,
QC prescribed in the methods provides information that is continually
used by the Agency to assess sample data quality, Contractor data
quality and Program data quality via data trend analysis. Trend
analysis is accomplished by entering data into a computerized database.
Statistical reports that evaluate specific anomalies or disclose trends
in many areas, including the following, are generated from this
database:
• Surrogate spike recovery,
• Laboratory evaluation sample results,
• Blanks,
• GC/MS instrument performance checks (BFB and DFTPP),
• Initial and continuing calibration data, and
• Other QC and method parameters.
12.2 Program-wide statistical results are used to rank Contractors in order
to observe the relative performance of each Contractor using a given
protocol against its peers. The reports are also used to identify
trends within Contractors. The results of many of these trend analyses
are included in the overall evaluation of a Contractor's performance,
and are reviewed to determine if corrective action or an on-site
laboratory evaluation may be required to ensure that the Contractor can
meet the QA/QC requirements of the contract. Contractor performance
over time is monitored using these trend analysis techniques to detect
departures of Contractor output from required or desired levels of
quality control, and to provide an early warning of Contractor QA/QC
problems which may not be apparent from the results of an individual
Case.
12.3 As a further benefit to the Program, the database provides the
information needed to establish performance-based criteria in updated
analytical protocols, where advisory criteria have been previously used.
The vast empirical data set produced by Contractors is carefully
analyzed, with the results augmenting theoretical and research-based
performance criteria. The result is a continuously monitored set of
quality control and performance criteria specifications of what is
routinely achievable and expected of environmental chemistry Contractors
engaged in mass production analysis of environmental samples. This, in
turn, assists the Agency in meeting its objectives of obtaining data of
known and documented quality.

Introduction
1.0 INTRODUCTION
1.1 A sample is physical evidence collected from a facility or from the
environment. Controlling evidence is an essential part of the hazardous
waste investigation effort. To ensure that the Environmental Protection
Agency's (EPA) sample data and records supporting sample-related
activities are admissible and have weight as evidence in future
litigation, Contractors are required to maintain EPA samples under
chain-of-custody and to account for all samples and supporting records
of sample handling, preparation, and analysis. Contractors shall
maintain sample identity, sample custody, and all sample-related records
according to the requirements in this exhibit.
1.2 The purposes of the evidence requirements include:
• Ensuring traceability of samples while in the possession of the
Contractor.
• Ensuring custody of samples while in the possession of the
Contractor.
• Ensuring the integrity of sample identity while in the possession of
the Contractor.
• Ensuring sample-related activities are recorded on documents or in
other formats for EPA sample receipt, storage, preparation,
analysis, and disposal.
• Ensuring all laboratory records for each specified sample delivery
group will be accounted for when the project is completed.
• Ensuring that all laboratory records directly related to EPA samples
are assembled and delivered to EPA or, prior to delivery, are
available upon EPA's request.

Format Characteristics
1.0 FORMAT CHARACTERISTICS
1.1 This constitutes an implementation of the EPA Agency Standard for
Electronic Data Transmission based upon analytical results and ancillary
information required by the contract. All data generated by a single
analysis are grouped together, and the groups are aggregated to produce
files that report data from an SDG. Because this implementation is only
a subset of the Agency Standard, some fields have been replaced by
delimiters as place holders for non-CLP data elements.
1.2 This implementation includes detailed specifications for the required
format of each record. The position in the record where each field is
to be contained relevant to other fields is specified, as well as the
maximum length of the field. Each field's required contents are
specified as literal (contained in quotes), which must appear exactly as
shown (without quotes), or as a variable for which format and/or
descriptions are listed in the format/contents column. Options and
examples are listed for most fields. For fields where more than three
options are available, a list and description of options are supplied on
a separate page following the record descriptions. Fields are separated
from each other by the delimiter ")" (ASCII 124). Fields that do not
contain data should be zero length or a blank field (empty with no space
or additional delimiters between the delimiters before and after the
field) with the delimiter as a place holder. For the purposes of
Section 9 of this exhibit, wherever "blank" is given as an option under
the "Format/Contents" column, it refers to a blank field as explained
above.
1.3 Numeric fields may contain numeric digits, a decimal place, and a
leading minus sign. A positive sign is assumed if no negative sign is
entered in a numeric field and shall not be entered into any numeric
field. Values that exceed the maximum length allowed shall be reported
to the maximum possible, maintaining the specified decimal place and
maximum field length restrictions.
1.4 Requirements for significant figures and number of decimal places are
specified in Exhibit B. The numeric field lengths are specified such
that all possible numeric values can be written to the file. The size
of the numeric field indicates the maximum number of digits, including a
decimal place and negative sign (if appropriate), that can appear in the
field at the same time. Therefore, the number reported may need to be
rounded (using rounding rules described in Exhibit B) to fit into the
field. The rounding shall maintain the greatest significance possible
providing the field length limitation. In addition, the rounded number
that appears on the form, and therefore in the field on the diskette
file, must be used in any calculation that may result in other numbers
reported on the same form or other forms in the SDG. The numbers/values
reported by the Contractor are used by CCS to calculate a result (e.g.,
CRQL). The final value calculated by CCS is then rounded according to
rounding rules described in Exhibit B and is used for comparison to the
final value (e.g., CRQL) reported by the Contractor. Field lengths
should only be as long as necessary to contain the data; packing with
blanks is not allowed.

Record Types
2.0 RECORD TYPES
2.1 The Agency Standard consists of variable length ASCII records. Maximum
field length specifications match the reporting requirements in Exhibit
B. The last two bytes of each record shall contain "carriage return"
and "line feed", respectively.
2.2 This implementation consists of twelve record types that can be
summarized in four groups, designated by the first record type in each
group:
Type Type ID Contents
Run Header 10 Information pertinent to a group of
samples processed in a continuous
sequence; usually several per SDG
Sample Header 20 Sample identifying, qualifying, and
linking information
Results Record 30 Analyte results and qualifications
Comments Record 90 Free form comments
2.3 A separate run header is used for volatiles (VOA), semivolatiles (SV),
and for each column analysis for pesticides (PEST) (minimum of four type
10 series for VOA/SV/PEST SDG). The 20 series records contain sample
character'sties and link samples within an SDG to the corresponding
calibrations, blanks, and other QCs. The 30 series records contain the
actual analytical results by analyte within each sample. The 10, 20,
and 30 records are associated with each other by their position in the
file (i.e., 30 series records follow the corresponding 20 series, which
in turn follow the 10 series run header records).

Production Runs
3.0 PRODUCTION RUNS
3.1 A production run represents a "group" or "batch" of samples that are
processed in a continuous sequence under relatively stable conditions.
Specifically:
3.1.1 Calibration - All samples in a run use the same initial calibration
data.
3.1.2 Method number - Constant throughout a run.
3.1.3 Instrument conditions - Constant throughout a run.
3.2 Each instrumental analysis consists of a separate production run and is
reported in a separate file. There will be a separate production run
for each of the two pesticide GC columns utilized. Thus, a full three
fraction analysis will consist of a minimum of four production runs.

Record Sequence
4.0 RECORD SEQUENCE
4.1 The sequence of records for Agency Standard files is as follows: A Run
Header (type 10) record shall be present once and once only (per file.)
as the first record in a file. Therefore, a complete VOA/SV/PEST SDG
will consist of several files.
4.2 Each environmental sample, calibration standard, or quality control
sample is represented by a group composed of type 20, 21, 22, 23, and 27
records, that hold sample level identifying information, followed by
type 30, 32, 33, and 36 records for each method analyte including
surrogates, system monitoring compounds, and internal standards in the
sample. The type 20 record holds a count for the number of method
analytes being determined and includes all target compounds, surrogates,
system monitoring compounds, and internal standards plus each peak of
the multi-component pesticides (do not include TICs in this count). A
separate field on the type 23 record contains the number of TICs found.
Type 20 records shall occur in the order of sample analysis. In
addition, a type 20 record with a QC code "MNC", followed by a type 30
record for each method analyte {reporting values such as mean response
factors) will appear after the type 10 or type 11 record and before the
type 20 record that initiates the analytical sequence. Similarly, for
pesticide runs, a type 20 record with a QC code "GPC" for GPC recovery,
followed by type 30 records for each of the method analytes spiked; and
a type 20 record with a QC code "FLO" for Florisil recovery, followed by
ty;3 30 records for each of the method analytes (and the two surrogates)
included . \ the Florisil check will appear before the type 20 record
that initiates the analytical sequence.
4.3 Type 90 comment records may be defined to occupy any position after the
type 10 (header) record.

First Field 2 Record type "10" or as appropriate
Last Field 5 Record sequence number 00001-99999, numbered
within file sequentially
4 Record checksum1 Four hexadecimal digits
2 Must contain CR and LF
6.0 DATES AND TIMES
Date or time-of-day information consists of successive groups of two
decimal digits, each separated by delimiters. Dates are given in the
order YY MM DD, and times as HH MM. All hours shall be given as 00 to
23 using a 24-hour clock and shall be local time. All days shall be
given as 01 to 31. All months shall be given as 01 to 12 (e.g., 01 is
January, 02 is February).
7.0 MULTIPLE VOLUME DATA
There is no requirement under this format that all the data from an
entire sample delivery group fit onto a single diskette. However, each
single production run must fit onto a single diskette if possible. If
that is not possible, then it is necessary that all files start with a
type 10 record, and that the multiple type 10 records for each file of
the same production run be identical. Information for a single sample
shall not be split between files.
The checksum is the sum of the ASCII representation of the data on the
record up to the Record Sequence Number (not including the Record Sequence
Number) plus the checksum of the previous record. The sum is taken modulo
65536 (216) and is represented as four hexadecimal digits (i.e., the
remainder of the sum divided by 65536 represented as four hexadecimal

8.1 The file shall be submitted on 5-1/4 inch floppy diskette(s), which may
be either double-sided, double density, 360 K-byte or high density
1.2 M-byte diskette(s). IBM-compatible, 3.5 inch double-sided, double
density 720 K-byte or high density 1.44 M-byte diskettes may also be
submitted. The diskettes shall be formatted and recorded using MS-DOS
Operating System. The diskettes shall contain all information relevant
to one and only one SDG.
8.2 Agency Standard data from an entire SDG may not fit onto a single
diskette. If a single production run is being split onto multiple
diskettes, then all files shall start with a type 10 record, and the
multiple type 10 records for each file of the same production run shall
be identical. Do not split the data from a single sample onto multiple
diskettes.
8.3 Information on the diskette must correspond to information submitted in
the hardcopy raw data package and on the hardcopy raw data package
forms. For example, type 30 results field specifies maximum length of
13. When reporting CRQLs or results on Form 1, maximum length is 13 as
is specified in this exhibit; when reporting 'calculated amounts' on
Form 7D, hardcopy specified maximum length is 8. Unused records shall
not be included on the diskettes. If the information submitted in the
hardcopy data package forms is changed, the information in the diskette
file shall be changed accordingly, and a complete diskette containing
all the information for the SDG shall be resubmitted along with the
hardcopy at no additional cost to the EPA.
8.4 Each diskette shall be identified with an external label containing (in
this order) the following information:
Disk Density
File Name(s)
Laboratory Name (optional)
Laboratory Code
Contract Number
Case Number/SDG
SAS Number (where applicable)
Initial Submission or Resubmission (as applicable) and Date
8.5 The format for File Name shall be XXXXX.O01 to XXXXX.O99. Where XXXXX
is the SDG identifier, O designates Organics, and 01 through 99 is the
file number.
8.6 Dimensions of the label must be in the range of 2-1/2" to 2-3/4" long by
1-1/4" to 1-1/2" wide for a 5-1/4 inch floppy diskette, and 2-1/2" to 2-
3/4" long by 2" to 2-1/8" wide for a 3-1/2 inch IBM-compatible diskette.
8.7 Section 9.0 (Record Listing) provides information for the usage of each
of the record types. Where specified, labels indicate the nature of the
value(s) that follow on that record. If the value(s) will not be
reported, the label shall be omitted.

pesticides (see Exhibit D PEST).
Response factors (GC/MS) or
Calibration Factors (pesticides)
will be reported on the following
type 30 records.
The Initial Toxaphene/Aroclor Mixes
used to determine all calibration
factors (see Exhibit D PEST).
The continuing calibration
(VSTD50/SSTD50) for GC/MS.
The subsequent Individual Standard
Mixes (A,B), Performance Evaluation
Mixture, and for subsequent
injections of Toxaphene/Aroclor
mixes for pesticides (see Exhibit D
PEST).
A calibration solution as above used
both as an initial calibration (CLM)
and a continuing check (CLC). (50
level initial calibration if needed
for Form 8.)
The following QCC values are used on type 20 records which act as a
header, and indicate that additional (usually calculated) analyte
specific data will be present on type 30 (and following type)
records. Usually, these data will apply to an entire production run,
in which case they will appear immediately following the type 10
record or type 11 record if present. If the data apply to only a
portion of the samples in the run, they shall be placed immediately
preceding the samples to which they apply. Much of the rest of the
information in the type 20 record may be blank, indicating that these
data do not apply to these results.

10.3 List of Sample and Result Qualifiers
Definition: A sample qualifier consists of three characters which act
as an indicator of the fact and the reason that the subject analysis (a)
did not produce a numeric result, or (b) produced a numeric result for
an entire sample but it is qualified in some respect relating to the
type or validity of the result.
10.3.1 Sample Qualifiers
Qualifier Full Name Definition
RIN RE-ANALYZED The indicated analysis results were
generated from a re-injection of the same
sample extract or aliquot (RE SUFFIX).
REX RE-PREPARED The indicated analysis results were
generated from a re-extraction of the same
sample (RE SUFFIX).
REJ REJECTED The results for the entire sample analysis
have been rejected for an unspecified
reason by the laboratory. For initial
calibration data, these data were not
utilized in the calculation of the mean.
SRN DILUTED The indicated analysis results were
generated from a dilution of the same
sample (DL SUFFIX).
10.3.2 Result Qualifiers in Type 30 Records
A result qualifier consists of three characters which act as an
indicator of the fact and the reason that the subject analysis (a)
did not produce a numeric result, or (b) produced a numeric result
for a single analyte but it is qualified in some respect relating to
the type or validity of the result. This qualifier is complementary
to the flags field on a type 30 record. A TIC must have either a
TIE, TFB, ALC, or PRE result qualifier.
BDL BELOW DETECTABLE Indicates compound was analyzed for but
LIMITS not detected (Form 1 "U" Flag).
NAR NO ANALYSIS RESULT There is no analysis result required
for this subject parameter.
