Introduction to the
Contract Laboratory Program
-------
Introduction
This document is designed to educate primarily EPA's Superfund staff and managers (e.g., Remedial Project
Managers, On Scene Coordinators, Site Assessment Managers, and Risk Assessors) in obtaining laboratory analytical
services for Superfund and Brownfields sites. The Contract Laboratory Program (CLP) is administered by OERR's
Analytical Operations/Data Quality Center (AOC), Regional CLP Project Officers, and Regional Sample Control Center
Coordinators. Other programs or agencies can "buy" into the CLP - please refer to the section on "CLP Participants"
in Chapter 1 and the AOC contact list in Appendix C.
CLP analytical data is used to demonstrate the nature and extent of contamination at hazardous waste sites,
assess priorities for response based on risks to human health and the environment, establish appropriate cleanup
actions, and determine when remedial actions are complete. Each CLP sample is properly documented to ensure
timely, accurate, and complete analysis for all parameters requested, and to support the use of sample data in
potential enforcement actions against responsible parties. Therefore the CLP is not available to the private sector
(e.g., Potentially Responsible Parties) since it is a federally funded program and use by private parties would cause
a conflict of interest.

Welcome to the Contract Laboratory
Program (CLP). The CLP is a
national network of Environmental
Protection Agency (EPA) personnel,
commercial laboratories, and
support contractors whose
fundamental mission is providing
customers with analytical data of
known and documented quality. Initiated in 1980, the CLP supports environmental data
users in identifying contaminants and determining the level of contamination at
Superfund hazardous waste sites prior to, during, and after site cleanup. (Note:
Potentially Responsible Parties (PRPs) cannot access the CLP).
Benefits of the CLP
Customer satisfaction is the key factor in the design and application of all CLP services.
The CLP supplies its customers with timely, high-quality, high-volume, low cost services
and solutions. Customers using the CLP receive the following benefits:
Analytical Services
• The CLP provides a variety of analytical services for the most
commonly requested organic and inorganic analytes. For a full listing
of CLP target compounds and analytes, please see the Fact Sheets for
the Inorganic, Organic, and Organic Low Concentration programs in
Appendix A. You may also obtain the Fact Sheets from the CLP Web
site at:
www.epa.gov/superfund/proqrams/clp/facts.htm
• The CLP provides environmental sample analysis, electronic and
manual data review, and compliance with EPA specifications, giving
customers a full spectrum of analytical services from a review of
sample results to a full assessment of analytical raw data.
Quality Assurance
• The CLP provides a comprehensive quality assurance (QA) program
through on-site audits, Performance Evaluation (PE) samples, quarterly
performance reports, fraud detection mechanisms, performance-based
scheduling, and continuous inspection of laboratory data for contractual
compliance.
• To simplify the Quality Assurance Project Plan (QAPP) development
process, the CLP predefines elements such as: analytical methods;
preventive laboratory equipment maintenance and calibration; sample
shipment Chain-of-Custody procedures and forms; analytical precision
and accuracy (including quantitation limits for organics and detection
limits for inorganics); laboratory quality control (QC) requirements; data
management; and documentation for laboratory analysis.

in Chapter 2 on page 9
The following activities and products demonstrate the CLP's success in providing its
customers with analytical and technical support services to achieve data of known and
documented quality.
Brownfields Initiatives
EPA's Brownfields Initiative is an effort to identify contamination and conduct
cleanup activities at various "Brownfield" sites across the United States. The
objective is to make these sites safe for use in a short period of time. In
FY1999, the CLP laboratories completed 84 separate projects involving the
analysis of more than 4,200 field samples for 64 Brownfields sites. The CLP
has provided, and continues to provide, Brownfields customers with certain
advantages, such as the CLP's comprehensive QC procedures, data turnaround
options, and low market prices with high quality that may not be available
through other analytical programs. To learn more about the Brownfields
Initiative, visit the Web site at:
http://www.epa.gov/swerosps/bf/
Federal Creosote Initiatives
In February 1998, EPA Region II requested assistance with the Federal
Creosote site in New Jersey. Because 140 residences stand upon the site,
Region II needed to quickly assess environmental damage and potential risks
to human health. The CLP processed more than 2,900 soil samples during a
4 week sampling period, with 80-100 samples shipped daily to the participating
laboratories. The Region required a fast turnaround of 14 days for analytical
data. Analytical Operations/Data Quality Center (AOC), CLP laboratories, and
CLP contractors worked in unison to provide Region II with the highest quality
analytical and support services possible, successfully meeting the Region's time
frame. As of January 2000, the CLP has analyzed more than 4,896 samples for
the Federal Creosote site.
Data Assessment Tool
During the Federal Creosote site project, AOC recognized the need for an
analytical tool that would facilitate the rapid transfer and storage of electronic
analytical data and would streamline the data validation process. To meet this
challenge, the CLP developed the Data Assessment Tool (DAT), a software-
driven process designed to produce enhanced CLP deliverables and more
usable reports. DAT allows Regional data users to electronically receive data
that has already been assessed by Contract Compliance Screening (CCS) and
Computer Aided Data Review and Evaluation (CADRE) data reviews. DAT
rapidly transfers electronic analytical data into any client database, foregoing the
need for manual data entry by the Regions. (Regional data validation has
typically required manual data entry of post-review data). Overall, DAT has
dramatically improved data turnaround times, making it possible to transmit
electronic data to the data validators and the ultimate customers (e.g., Regional
Project Managers (RPMs), site assessors, on-scene coordinators). DAT
performed so well that AOC made it available to all Regions following the
Federal Creosote site project. AOC can now provide data assessment reports
to CLP customers within 24 to 48 hours of receipt of data.

Analytical Data
The CLP provides analytical data that is used to help define the nature and
extent of contamination at Superfund sites. This allows customers to:
• Assess priorities for response based on the risk to human health and the
environment;
• Determine appropriate cleanup; and
• Determine when remedial actions are complete.
CLP data is used in all stages of hazardous waste site investigation, including
site inspections, Hazard Ranking System (HRS) scoring, remedial investigation
and feasibility studies, remedial design, treatability, remedial and removal
actions, operations and maintenance, and enforcement and litigation activities.
The CLP requires that any data produced within the program be of known and
documented quality.

CLP Services and Activities
This chapter provides guidance for initiating and using Contract Laboratory Program
(CLP) services. It also provides information on several CLP-related software products
available to CLP customers. You can begin using CLP services by contacting AOC.
Please see Appendix C for contact information.
Initiating CLP Analytical Services
The first step in accessing CLP services is determining if the CLP is the right program
for your purposes. The CLP offers numerous advantages to its customers (see Benefits
of the CLP in Chapter 1) that may not be available in other programs. Also, you must
determine if the site you wish to sample from is a Superfund site. If the site is part of the
Superfund, then follow the steps below. If it is not a Superfund site, proceed to Non-
Superfund Support on page 8.
Requesting CLP Analytical Services
Once you have decided to use the CLP, the next step is requesting analytical
services. (Note: Each Region may have different steps for initiating analytical
services. The following is only a general description.) Current and new CLP
customers may request routine analytical services through an EPA Regional
Sample Control Center (RSCC). The RSCC schedules all CLP analysis
requests through the Sample Management Office (SMO). SMO and the RSCC
work together during sampling events to ensure all samples arrive at the
laboratories as scheduled and to resolve any issues that may arise during
sample analysis. Each RSCC is responsible for maintaining a working
knowledge of current CLP Statements of Work (SOWs) to assist the customer
in choosing the proper analytical method. (Note: The CLP requires "lead time"
in order to secure laboratory space for sampling projects. Routine Analytical
Service projects must be scheduled with the CLP by noon on the Wednesday
prior to the week of sample shipment).
You will need to supply the RSCC with the following types of information (Note:
There may be additional information required for your particular Region):
• Site name;
• Site location;
• Operable unit of the site where you want the sampling to take place. (The
operable unit is a specific portion of a whole site);
• Type(s) of analysis you require;
• Purpose of your sampling event (e.g., Site Assessment (SA), Remedial
Design (RD), Remedial Action (RA), etc.);
• Period of time during which the sampling will take place;
• Site identification numbers (e.g., CERCLIS ID, Site Spill ID);
• Data turnaround time required for your project;
• Fax number for preliminary results, if required; and
• Site specific Quality Assurance Project Plan (QAPP).
The CLP is available to EPA Regions, state, territorial, and tribal governments,
government agencies, and other EPA offices interested in receiving analytical
services at reasonable costs with full QA and quality controls (QC). (Contact
AOC for more information. See Appendix C.)

Non-Superfund Support
Hie CLP also provides analytical and support activities to non-
Superfund analyses customers through the transfer of funds from
a non-Superfund program (e.g., RCRA, Office of Water). If you
wish to utilize CLP services for non-Superfund activities, please
contact the CLASS Project Officer at AOC, AOC will facilitate the
funds transfer process and direct the sample analysis request to
the appropriate EPA Regional Office. To contact AOC for this
service, see the CLP Contacts in Appendix C or visit the CLP Web
site.
Determining the Proper Statement of Work
The next step in accessing analytical services through the CLP is deciding which
analytical services best meet your needs. The CLP currently offers three SOWs
for CLP inorganic, organic, and organic low concentration analytical services.
Each of the SOWs provides the technical and contractual conditions for
laboratories to apply EPA/CLP analytical methods for the isolation, detection,
and quantitative measurement for the most common environmental pollutants.
Contact the specified AOC Program Manager for further information. Refer to
the CLP Contacts in Appendix C for the appropriate contact information.
NOTE: The SOWs listed below are not designed to handle radioactive
samples, such as those that might come from Department of Energy sites,
or samples with very high concentrations of contamination or product type
samples. AOC does have some SOWs {e.g., SOW IHC01.3) that may be
used to procure laboratory services for high concentration samples.
However, these contracts are currently not active. Potentially radioactive
samples will need to be handled on a case-by-case basis.
The Inorganic SOW (ILM04.1)
The Inorganic SOW sets the requirements for the analysis of 23 metal inorganic
target analytes and cyanide in water and soil/sediment samples. Inorganic
analysis is conducted using inductively coupled plasma (ICP), atomic absorption
(AA), and colorimetric methods. Data is delivered in either 7, 14, or 21 days.
The customer may specify any of the three turnaround times when requesting
CLP inorganic analytical services. Preliminary results are available within 72
hours for all turnaround times.
For a complete list of the inorganic target analytes and more information about
the inorganic analytical service, see the Multi-Media, Multi-Concentration,
Inorganic Analytical Service for Superfund (ILM04.1) Fact Sheet in Appendix A.
The Organic SOW (OLM04.2)
The Organic SOW sets the requirements for the analysis of 48 volatile, 65
semivolatile, and 28 pesticide/Aroclor (PCB) target compounds in water and
soil/sediment samples. Organic compounds are analyzed using gas
chromatography coupled with mass spectrometry (GC/MS) or an electron
capture detector (GC/ECD). Data delivery is available in 7,14, or 21 days, any
of which may be specified when requesting CLP organic analytical services.
Preliminary results are available within 48 hours for volatiles and 72 hours for
semivolatiles and pesticides/Aroclors (PCBs) underthe 7-day turnaround option.

The Organic Low Concentration SOW (OLC02.1)
The Organic Low Concentration SOW sets the requirements for the analysis of
41 volatile, 59 semivolatile, and 28 pesticide/Aroclor (PCB) target organic
compounds in low concentration groundwaterand drinking water samples. The
lowest concentration limit for volatile analysis is 1 part per billion (ppb), 5 ppb for
semivolatile analysis, and 0.01 ppb for pesticide/Aroclor (PCB) analysis. Data
delivery is available in 14 days.

Fact Sheets, and National Functional Guidelines. Appendix B also
provides information on where to obtain these documents.
CLP Software Tools
The CLP's commitment to quality does not end with data. In an effort to bring faster and
more efficient services to our customers, the CLP has developed a number of software
solutions that streamline data review and QC, contract compliance, and administrative
tasks, while promoting the sharing of analytical information.
Data Assessment Tool
The Data Assessment Tool (DAT) is a software-driven process designed to produce
enhanced CLP deliverables and more usable reports in a standard format. DAT
incorporates Contract Compliance Screening (CCS), Computer Assisted Data Review
and Evaluation (CADRE), and Data Assessment Rapid Transmittal (DART) to provide
EPA customers with PC-compatible reports and electronic files that can be transferred
into client databases and programs for end users, and to provide a complete CLP data
assessment package. The electronic reports reduce the need for manual data entry and
duplicate entry of information. All CLP customers receive data that has been processed
through CLP data assessment tools within 24 to 48 hours after that laboratory data is
received. The resultant spreadsheets are delivered directly to the data requesters (e.g.,
RSCCs) email addresses, in a format (e.g., Lotus) specified by the Regional customer.
DAT does not include determination of data usability, qualification of data based on
professional judgment, evaluation of data based on its intended use, or compliance with
a site's Quality Assurance Project Plan (QAPP) or Sampling and Analysis Plan (SAP).

Contract Compliance Screening
The Contract Compliance Screening (CCS) system is a data verification tool
used to determine if a- laboratory's data submission is complete and
contractually compliant with CLP SOW terms and conditions included in its
contract. Following the evaluation, CCS produces a report detailing the
evaluation results.
Computer Aided Data Review and Evaluation
The Computer Aided Data Review and Evaluation (CADRE) system evaluates
QC results against data review criteria appropriate for the corresponding
analytical method/procedure. The CADRE system has predefined CLP method
information and data reyiew/QC criteria. However, it can be customized to
support variations on the analytical techniques employed by the CLP and to
review data according to project-specific QC criteria. CADRE uses both
Regional and National Functional Guidelines as the QC criteria (e.g., holding
times, percent moisture) to review and evaluate electronic analytical data.
Data Assessment Rapid Transmittal
Data Assessment Rapid Transmittal (DART) is an active notification system
providing up-to-the-minute transmittal of the CCS and CADRE evaluation report
data to CLP customers. DART also provides customers with a comprehensive
audit trail and transaction record by logging reader and recipient IDs, as well as
access times and dates after an email has been opened. DART is a
"user-friendly" system that operates on both DOS and Microsoft Windows
platforms.
DART provides customers with a variety of other reports, such as
Lotus/Microsoft Excel spreadsheets or an electronic file in Agency Standard
Format via the Internet.
Field Operations Records Management System II Lite
The Field Operations Records Management System II (FORMS II Lite) is designed for
customer use during the sampling event. FORMS II Lite automates the printing of
labels, custody seals, Traffic Reports, and Chain-of-Custody records to improve field
time management. FORMS II Lite captures critical collection information in an electronic
format early in the field sampling process.
FORMS II Lite enables field personnel to easily document, track, and transmit field
sample information to the laboratories. In addition, by electronically capturing this
information early in the tracking and reporting process, field sampling data is readily
accessible for transmittal to laboratories, RSCCs, and other data users. As of February
2000 all 10 Regions, 13 states and tribal governments, and one Federal agency have
received the FORMS II Lite 4.0 production version of the software.

Enforcement and Cost Recovery Support
The CLP provides
litigation support
The CLP assists «3°
customers in recouping
analytical and site
cleanup costs
The CLP has established detailed procedures and documentation to ensure that the
sample data is tracked from the time of sample collection to introduction as evidence in
legal proceedings. The CLP also provides documentation for program analytical costs
to support Superfund cost recovery efforts. Cost recovery is designed to assist CLP
customers in recouping the CLP analytical and cleanup costs they have spent on a
hazardous waste site.
Requesting Enforcement Support
Litigation procedures often necessitate the use of CLP data generated from the
analysis of samples collected. The CLP offers a variety of services to support
enforcement activities, which include:
• Arranging for the delivery of all laboratory and evidence documentation
relating to specific sample analyses;
• Augmenting customer resources for analytical data review; and
• Assisting in arranging for expert testimony by laboratory or CLP personnel.
Client requests for enforcement support are initially coordinated through the
Cost Recovery Contact at AOC (refer to the CLP Contacts in Appendix C). AOC
will review the request and determine the appropriate CLP response, including
the provision of EPA Regional or contractor resources needed to respond to the
request.
Requesting Cost Recovery Support
The CLP's cost recovery support normally consists of financial and analytical
documentation. The following forms of documentation are available to support
cost recovery requests:
Reports which detail all CLP analytical and management costs associated
with a site;
Lists of CLP projects associated with a site;
Sample analysis results; and
Lists of each invoice associated with a particular site.
Non-standard ad-hoc reports also may be prepared if necessary. Individuals
interested in requesting cost recovery support should refer to the CLP Contacts
in Appendix C.
If necessary, the cost recovery personnel will coordinate efforts with the other
EPA offices or contractor resources in order to produce or acquire cost recovery
documentation.

Quick Reference Fact Sheet
Under the legislative authority granted to the U.S. Environmental Protection Agency (EPA) under the Comprehensive
Environmental Response, Compensation, and Liability Act of -1980 (CERCLA) and the Superfund Amendments and
Reauthorization Act of 1986 (SARA), EPA develops standardized analytical methods for the measurement of various pollutants
in environmental samples from known or suspected hazardous waste sites. Among the pollutants that are of concern to EPA
at such sites are a series of inorganic analytes and cyanide that are analyzed using inductively coupled plasma (ICP), atomic
absorption (AA), and colorimetric techniques. The Analytical Operations/Data Quality Center (AOC) of the Office of
Emergency and Remedial Response (OERR) offers an analytical service that provides data from the analysis of water and
soil/sediment samples for inorganic analytes for use in the Superfund decision-making process. Through a series of standardized
procedures and a strict chain-of-custody, the inorganic analytical service produces data of known and documented quality. This
service is available through the Superfund Contract Laboratory Program (CLP).
DESCRIPTION OF SERVICES
The inorganic analytical service provides a technical and
contractual framework for laboratories to utilize EPA/CLP
analytical methods. These methods are used in the
preparation, detection, and quantitative measurement of
cyanide and 23 inorganic target analytes in both water and
soil/sediment environmental samples. The CLP provides
the methods to be used and the specific technical, reporting,
and contractual requirements, including quality assurance,
quality control, and standard operating procedures, by
which EPA evaluates the data. This service uses ICP, AA,
and colorimetric methods to analyze the inorganic target
analytes and cyanide. Three data delivery turnarounds are
available to CLP customers: 7,14, and 21-day turnaround
after receipt of the last sample in the set. In addition, a 72-
hour preliminary data submission option also is available
for all turnaround times.
DATA USES
This analytical service provides data that EPA uses for a
variety of purposes. Examples include 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.
TARGET ANALYTES
The analytes and detection limits for which this service is
applicable are listed in Table 1. The list of target analytes
for this service was originally derived from the EPA
Priority Pollutant List of 129 compounds. In the years
since the inception of the CLP, analytes have been added
to and deleted from the Target Analyte List, based on
advances in analytical methods, evaluation of method
performance data, and the needs of the Superfund program.
Specific detection limits are highly matrix dependent.
* ILM04.1 is an interim inorganic analytical service. Further changes are expected to be released under ILM05.0 for competition during calendar
year 2000.

Sample concentration exceeding five times the
detection limit of the instrument or method in use
may be reported even though the instrument or
method detection limit is greater than the CRDL.
This is illustrated in the following example:
For lead:
Method in use = ICP
Instrument Detection Limit (IDL) = 40
Sample Concentration = 220
CRDL =3
'The CRDL is the instrument detection limit obtained
in pure water.
METHODS AND INSTRUMENTATION
When storing samples, the use of a cooler temperature
indicator bottle and the cooler temperature must be
reported on Form DC-1 and in the Sample Delivery Group
(SDG) Narrative. When applying AA methods, the
Contractor may analyze the sample at a dilution so long as
the raw concentration or absorbence of the diluted sample
falls within the upper half of the calibration range. For
ICP, an undiluted analysis of the sample is required.
If an insufficient sample amount (less than 90% of the
required amount) is received to perform the analyses, the
Contractor must contact the Sample Management Office
(SMO) to report the problem. The same is required for
multi-phase samples (e.g., two-phase liquid sample and
oily sludge/sandy soil sample).
Table 2 summarizes the methods and instruments used in
this analytical service.
DATA DELIVERABLES
Data deliverables for this service include both hardcopy/
electronic data reporting forms and supporting raw data.
The laboratory must submit data to EPA within 7,14,21-
days, or preliminary data must be submitted within 72
hours after laboratory receipt of each sample in the set.
EPA then processes the data through an automated Data
Assessment Tool (DAT). DAT is a complete CLP data
assessment package. DAT incorporates Contract Com-
pliance Screening (CCS) and Computer-Aided Data
Review and Evaluation (CADRE) to provide EPA Regions
with PC-compatible reports, spreadsheets, and electronic
files. These files can be provided to the Regions within 24
to 48 hours from the receipt of the data and can be used as
a tool during the data validation process at the Region.
This automated tool facili tales the transfer of analytical data
into Regional databases. In addition to the Regional
electronic reports, the CLP laboratories are provided with
a data assessment report that documents the instances of
noncompliance. The laboratory has 4 days to reconcile
defective data and resubmit the data to EPA. EPA then
reviews the data for noncompliance and sends a final data
assessment report to the CLP laboratory and the Region.
QUALITY ASSURANCE
The quality assurance (QA) process consists of
management review and oversight at the planning,
implementation, and completion stages of the
environmental data collection activity. This process
ensures that the data provided are of the quality required.

During the data collection effort, QA activities ensure that
the quality control (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 to determine
its suitability to support enforcement or remedial decisions.
Each contract laboratory prepares a quality assurance plan
(QAP) with the objective of providing sound analytical
chemical measurements. The QAP must specify the
policies, organization, objectives, functional guidelines,
and QA/ QC activities designed to achieve the data quality
requirements for this analytical service.
QUALITY CONTROL
The QC process includes those activities required during
analytical data collection to produce data of known and
documented quality. The analytical data acquired from QC
procedures are used to estimate and evaluate the analytical
results and to determine the necessity for, or the effect of,
corrective action procedures. The QC procedures required
for this analytical service are shown in Table 3.
PERFORMANCE MONITORING ACTWITIES
Laboratory performance monitoring activities are provided
primarily by AOC and the Regions to ensure that contract
laboratories are producing data of the appropriate quality.
EPA performs on-site laboratory audits, data package
audits, and evaluates laboratory performance through the
use of blind performance evaluation samples.

Quick Reference Fact Sheet
Under the legislative authority granted to the U.S. Environmental Protection Agency (EPA) under the Comprehensive
Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) and the Superfund Amendments and
Reauthorization Act of 1986 (SARA), EPA develops standardized analytical methods for the measurement of various pollutants
in environmental samples from known or suspected hazardous waste sites. Among the pollutants that are of concern to the EPA
at such sites, are a series of volatile, semi volatile, and pesticide/Aroclor (pesticide/PCB) compounds that are analyzed using
gas chromatography coupled with mass spectrometry (GC/MS) and gas chromatography with an electron capture detector
(GC/ECD). The Analytical Operations/Data Quality Center (AOC) of the Office of Emergency and Remedial Response
(OERR) offers an analytical service that provides data from the analysis of water and soil/sediment samples for organic
compounds for use in the Superfund decision-making process. Through a series of standardized procedures and a strict
chain-of-custody, the organic analytical service produces data of known and documented quality. This service is available
through the Superfund Contract Laboratory Program (CLP).
OVERVIEW OF MAJOR CHANGES
The new organic analytical service provides a technical and
contractual framework for laboratories to apply EPA/CLP
analytical methods for the isolation, detection, and
quantitative measurement of target compounds in water and
soil/sediment environmental samples. The following
service items were added or modified to better serve our
customers.
i. All references to 14-day and 35-day data
turnaround times were removed. With
OLM04.2, laboratories now have 7-, 14-, or 21-
day turnaround times for analyses after
laboratory receipt of the last sample in the
sample delivery group (SDG). Under the 7-day
turnaround option, preliminary data can be
obtained within 48 hours (for volatile analyses)
or 72 hours (for semivolatile and
pesticide/Aroclor [pesticide/ PCB] analyses).
ii. The definition of an SDG was modified to
include samples received over a 7-dav period
(was 14 days) regardless of contract turnaround
time, and the maximum of 20 samples in an SDG
now excludes Performance Evaluation (PE)
samples. In addition, laboratories are now
required to prepare and analyze PE samples
concurrently with samples in the SDG, and all
samples and sample fractions assigned to an SDG
must be scheduled under the same contractual
turnaround time.
iii. The number of volatile and semivolatile
compounds has been modified to include 10 new
volatile compounds and five new semivolatile
compounds. In addition, four semivolatile
compounds were moved to the volatile target
compound list. The compounds that have been
added or moved are detailed in the
Modifications To Target Compounds section
and shaded in Table 1.
iv. Modified the delivery schedule for Sample
Traffic Reports from "5 working days" to "3
working days" to accommodate the new data
turnaround requirements.
v. Includes the optional use of Modified SW-846
Method 5035 using a closed system purge-and-
trap method for low-level volatile soil analysis
and of methanol preserved field samples for
medium level volatile soil analysis.
A-7
-------
VI.
VII.
Users may now request modifications to the
specified methodologies that may include, but are
not limited to, additional compounds and
modified quantitation limits.
SW-846 methods 3541 and 3545 (Automated
Soxhlet Extraction and Pressurized Fluid
Extraction) were added for optional use if
laboratories demonstrate equivalence and the
laboratory is approved by the EPA. These
alternative extraction techniques provide the
laboratories with the option to use extraction
procedures that require less solvent.
MODIFICATIONS TO TARGET COMPOUNDS
Since the CLP began in 1980, compounds have been
added and removed from the Target Compound List (TCL)
based on advances in analytical methods, evaluation of
method performance data, and to meet the needs of
Superfund program participants. Compounds that have
been added or moved in the SOW are shaded in Table 1.
The following modifications were made to the organic
analytical service target compounds.
i. New volatile compounds include:
dichlorodifluoromethane, trichlorofluoro-
methane, 1,1,2-trichloro-1,2,2-trifluoroethane,
methyl acetate, trans-1,2-dichloroethene, methyl
tert-buytl ether, cis-1,2-dichloroethene, cyclo-
hexane, methylcyclohexane, 1,2-dibromoethane,
isopropylbenzene, and 1,2 dibromo-3-chloro-
propane.
ii. Compounds moved from semivolatiles to
volatiles are: 1,2-dichlorobenzene, 1,3-di-
chlorobenzene, 1,4-dichlorobenzene, and 1,2,4-
trichlorobenzene.
iii. New semivolatile compounds include: benz-
aldehyde, acetophenone, caprolactam, 1,1'-bi-
phenyl, and atrazine.
MODIFICATIONS TO METHODS AND
INSTRUMENTATION
Current methods and instrumentations have been modified
in an effort to allow CLP participants to use newer
technologies or address previous issues. The following
items summarize the modifications to the organic
analytical service.
i. The absence of a temperature indicator bottle is
addressed by using an alternative procedure to
determine the cooler temperature.
ii. The analysis of matrix spikes and matrix spike
duplicates is now optional and will be required
on a case-by-case basis at the request of the
customer.
iii. "Gel Permeation Chromatography (GPC)
Calibration" now includes "GPC Calibration and
Continuing Calibration Verification (CCV)". In
addition, the GPC cleanup procedures are based
on manufacturer's specifications.
iv. In addition to SOW specified screening
procedures, laboratories may now use other EPA
approved screening procedures, as well as their
own in-house screening procedures, for
determining if low or medium level analytical
methods should be used.
v. Modified methods may be performed after a
written request has been approved by the
Regional CLP Project Officer (PO) and
laboratory Contracting Officer (CO). For
example, additional compounds may be
requested or quantitation limits may be adjusted.
Volatiles
The following items were added for volatiles.
i. Specific procedures are included for the
collection and weighing of low and medium level
soil samples for analysis by Modified SW-846
Method 5035.
ii. Procedures were incorporated to address the
preparation and analysis of samples using
Modified SW-846 Method 5035.
iii. Guidance is provided for the analysis of storage
blanks when an SDG contains only soil samples.
iv. The composition of the "trap" portion of the
purge-and-trap device was modified to
incorporate 7 cm of coconut charcoal. This
modification was made to accommodate new
target compounds.
Semivolatiles and Pesticides/Aroclors (Pesticides/PCBs)
i. The frequency of method blanks was clarified to
require that a method blank be extracted each
time samples are extracted; the number of
samples extracted with each method blank shall
not exceed 20 samples; the method blank shall be
extracted by the same procedure used to extract
samples; and the method blank shall be analyzed
on each GC/MS system used to analyze
associated samples.
A-8
-------
ii. The following items were added for the optional
use of SW-846 methods 3541 and 3545
(Automated Soxhlet Extraction and Pressurized
Fluid Extraction).
• Language was added for the
determination of method equivalency
for alternative extraction procedures.
• Specific instructions were provided
allowing laboratories to utilize
alternative extraction methods, if pre-
approved by EPA.
MODIFICATIONS TO REPORTING
REQUIREMENTS AND DATA DELIVERABLES
Data deliverables for this service include hardcopy data
reporting forms and supporting raw data. In addition to the
hardcopy deliverable, contract laboratories must submit the
same data on diskette (or via an alternate means of
electronic transmission if approved in advance by EPA).
Below are modifications that affect data deliverables.
i. The two most recent UV traces of the GPC
semivolatile calibration solution are now
required for submission.
ii. Requirements were modified for reporting
tentatively identified compounds (TICs) for
which a library match of 85% or greater is
obtained. The name of the compound with the
best match must be reported as the TIC, whether
or not there was a positive identification.
111.
IV.
v.
Instructions were incorporated regarding data to
be supplied in instances where no airbill is
received.
Additional instructions are provided for the
requirements and items included on tape audits
(magnetic tapes). Tape audit requirements now
apply to GC/ECD data in addition to the
previously required GC/MS data.
Modified the assignment of an SDG number to
include instructions for assigning SDG numbers
for fractions of the same field samples scheduled
under different turnaround times.
VI.
Modified the electronic reporting
information to be Y2K compliant.

Under the legislative authority granted to the U.S. Environmental Protection Agency (EPA) under the Comprehensive
Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) and the Superfund Amendments and
Reauthorization Act of 1986 (SARA), EPA develops standardized analytical methods for the measurement of various pollutants
in environmental samples from known or suspected hazardous waste sites. Among the pollutants that are of concern to the EPA
at such sites, are a series of volatile, semivolatile, and pesticide/Aroclor (pesticide/PCB) compounds that are analyzed using
gas chromatography coupled with mass spectrometry (GC/MS) and gas chromatography with an electron capture detector
(GC/ECD). The Analytical Operations/Data Quality Center (AOC) of the Office of Emergency and Remedial Response
(OERR) offers an analytical service that provides data from the analysis of water and soil/sediment samples for organic
compounds for use in the Superfund decision-making process. Through a series of standardized procedures and a strict
chain-of-custody, the organic analytical service produces data of known and documented quality. This service is available
through the Superfund Contract Laboratory Program (CLP).
DESCRIPTION OF SERVICES
The new organic analytical service is available as of
September 1999. It provides a technical and contractual
frame work for laboratories to apply EPA/CLP analytical
methods for the isolation, detection, and quantitative
measurement of 48 volatile, 65 semivolatile, and 28
pesticide/Aroclor (pesticide/PCB) target compounds in
water and soil/sediment environmental samples. The CLP
provides the methods to be used and the specific technical,
reporting, and contractual requirements, including quality
assurance (QA), quality control (QC), and standard
operating procedures (SOPs), by whichEPA evaluates the
data. This service uses GC/MS and GC/ECD methods to
analyze the target compounds. Three data delivery
turnarounds are available to CLP customers: 7,14,and21-
day turnaround after laboratory receipt of the last sample in
the set. In addition, there are 48 (for volatiles) and 72-hour
[for semivolatiles and pesticides/Aroclors
(pesticides/PCBs)] preliminary data submission options
available. New options under this service include a closed
system purge-and-trap method for low level volatile soil
analysis and methanol preservation for medium level
volatile soil analysis. In addition, users may request
modifications to the specified methodologies that may
include, but are not limited to, additional compounds and
modified quantitation limits.
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 will be
available for use in Superfund enforcement/litigation
activities.
TARGET COMPOUNDS
The compounds for which this service is applicable and the
corresponding quantitation limits are listed in Table 1. For
water samples, the lowest quantitation limits reportable are
10 ppb for the volatile compounds, 10 ppb for the
semivolatile compounds, and 0.05 ppb for the
pesticide/Aroclor (pesticide/PCB) compounds. For soil
samples, the lowest quantitation limits reportable are 10 ppb
for the volatile compounds, 330 ppb for the semivolatile
compounds, and 1.7 ppb for the pesticide/

-------
Aroclor (pesticide/PCB) compounds. Specific sample
quantitation limits will be highly matrix dependent.
Compounds identified with concentrations below the
quantitation limit will be reported as estimated
concentration values.
The list of target compounds for this service was originally
derived from the EPA Priority Pollutant List of 129
compounds. In the years since inception of the CLP,
compounds have been added to and removed from the
Target Compound List (TCL), based on advances in
analytical methods, evaluation of method performance
data, and the needs of the Superfund program.
For drinking water and groundwater type samples, use of
the low concentration organic analytical service is
recommended.
METHODS AND INSTRUMENTATION
For semivolatile and pesticide/Aroclor (pesticide/PCB)
water samples, a 1-L aliquot is extracted with methylene
chloride using a continuous liquid-liquid extractor or
separatory funnel [for pesticides/Aroclors
(pesticides/PCBs) only]. For low level semivolatile soil
and pesticide/Aroclor (pesticides/PCBs) soil samples, a
30-g soil/sediment sample is extracted with methylene
chloride/acetone using sonication, automated soxhlet, or
pressurized fluid extraction techniques. For medium level
semivolatile soil samples, a 1 -g aliquot is extracted with
methylene chloride using the techniques mentioned above
for low level soil samples. For both water and soil
samples, the extract is concentrated, subjected to
fraction-specific cleanup procedures, and analyzed by
GC/MS for semivolatiles or GC/ECD for
pesticides/Aroclors (pesticides/PCBs).
For volatile water samples, 5 mL of water is added to a
purge and trap device and purged with an inert gas at room
temperature. For volatile low level soil samples, a 5-g
aliquot of soil is added to a purge and trap device with 5
mL of reagent water then purged with an inert gas at 40°C;
or a 5-g aliquot (pre-weighed in the field) is purged from a
closed-system purge and trap device at 40°C. For volatile
medium level soil samples, a measured amount is
collected/extracted with methanol and an aliquot of the
methanol extract is added to reagent water and purged at
room temperature. For both water and soil samples, the
volatiles purged from the sample are trapped on a solid
sorbent. They are subsequently desorbed by rapidly
heating the sorbent and then introduced into a GC/MS
system. Table 2 summarizes the methods and instruments
used in this analytical service.
DATA DELIVERABLES
Data deliverables for this service include hardcopy data
reporting forms and supporting raw data. In addition to the
hardcopy deliverable, contract laboratories must also
submit the same data electronically. The laboratory must
submit data to EPA within 7, 14, or 21-days [or
preliminary data within 48 hours (for volatiles)] or 72
hours [for semivolatiles and pesticides/Aroclors
(pesticides/PCBs)] after laboratory receipt of the last
sample in the set. EPA then processes the data through an
automated Data Assessment Tool (DAT). DAT is a
complete CLP data assessment package. DAT
incorporates Contract Compliance Screening (CCS) and
Computer-Aided Data Review and Evaluation (CADRE)
review to provide EPA Regions with PC-compatible
reports, spreadsheets, and electronic files within 24 to 48
hours from the receipt of the data for data validation. This
automated tool facilitates the transfer of analytical data into
Regional databases. In addition to the Regional electronic
reports, the CLP laboratories are provided with a data
assessment report that documents the instances of
noncompliance. The laboratory has 10 days to reconcile
defective data and resubmit the data to EPA. EPA then
reviews the data for noncompliance and sends a final data
assessment report to the CLP laboratory and the Region.
QUALITY ASSURANCE
The quality assurance (QA) process consists of
management review and oversight at the planning,
implementation, and completion stages of the
environmental data collection activity. This process
ensures that the data provided are of the quality required.
During the implementation of the data collection effort, Q A
activities ensure that the quality control (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 to determine its suitability to support enforcement
or remedial decisions.
Each contract laboratory prepares a quality assurance plan
(QAP) with the objective of providing sound analytical
chemical measurements. The QAP must specify the
policies, organization, objectives, and functional
guidelines, as well as the QA and QC activities designed
to achieve the data quality requirements for this analytical
service.
QUALITY CONTROL
The QC process includes those activities required during
analytical data collection to produce data of known and
documented quality. The analytical data acquired from QC
procedures are used to estimate and evaluate the analytical
results and to determine the necessity for, or the effect of,
corrective action procedures. The QC procedures required
for this analytical service are shown in Table 3.

PERFORMANCE MONITORING ACTIVITIES
Laboratory performance monitoring activities are
provided primarily by AOC and the Regions to ensure
that contract laboratories are producing data of the
appropriate quality. EPA performs on-site laboratory
audits, data package audits, GC/MS and/or GC/ECD
tape audits, and evaluates laboratory performance
through the use of blind performance evaluation
samples.

Quick Reference Fact Sheet
Under the legislative authority granted to the U.S. Environmental Protection Agency (EPA) under the Comprehensive Environmental
Response, Compensation, and Liability Act of 1980 (CERCLA) and the Superfund Amendments and Reauthorization Act of 1986
(SARA), EPA develops standardized analytical methods for the measurement of various pollutants in environmental samples from
known or suspected hazardous waste sites. Among the pollutants that are of concern to the EPA at such sites, are a series of volatile,
semivolatile, and pesticide/Aroclor (pesticide/PCB) compounds that are analyzed using gas chromatography coupled with mass
spectrometry (GC/MS) and gas chromatography with an electron capture detector (GC/ECD). The Analytical Operations/Data Quality
Center (AOC) of the Office of Emergency and Remedial Response (OERR) offers an analytical service that provides data from the
analysis of groundwater and drinking water type samples for organic compounds for use in the Superfund decision-making process.
Through a series of standardized procedures and a strict chain-of-custody, the low concentration organic analytical service produces
data of known and documented quality. This service is available through the Superfund Contract Laboratory Program (CLP).
DESCRIPTION OF SERVICES
The low concentration organic analytical service provides
a technical and contractual framework for laboratories to
apply EPA/CLP analytical methods for the isolation,
detection, and quantitative measurement of 41 volatile, 59
semivolatile, and 28 pesticide/Aroclor (pesticide/PCB)
target compounds in low concentration groundwater and
drinking water type samples. The CLP provides the
methods to be used and the specific technical, reporting,
and contractual requirements, including quality assurance,
quality control, and standard operating procedures, by
which EPA evaluates the data. The data turnaround time
for this contract is 14 days after laboratory receipt of the
last sample in the set.
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 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.
TARGET COMPOUNDS
The compounds and quantitation limits for which this
service is applicable are listed in Table 1. The lowest
quantitation limits reportable are 1 ppb for the volatile
compounds, 5 ppb for the semivolatile compounds, and
0.01 ppb for the pesticide/Aroclor (pesticide/PCB)
compounds. Specific sample quantitation limits are highly
matrix dependent. The list of target compounds for this
service was originally derived from the EPA Priority
Pollutant List of 129 compounds. In the years since the
inception of the CLP, compounds have been added to and
deleted from the Target Compound List (TCL), based on
advances in analytical methods, evaluation of method
performance data, and the needs of the Superfund
program.

multi-concentration organic analytical service.
PREPARATION METHODS AND
INSTRUMENTATION
For semivolatile and pesticide/Aroclor (pesticide/PCB)
water samples, a 1-L aliquot is extracted with methylene
chloride using continuous liquid-liquid extraction or
separatory funnel [for pesticides/Aroclors
(pesticides/PCBs) only]. The extract is concentrated,
subjected to fraction-specific cleanup procedures, and
analyzed by GC/MS for semivolatiles or GC/ECD for
pesticides/Aroclors (pesticides/PCBs). For volatiles, 25
mL of water is added to a purge-and-trap device and
purged with an inert gas at room temperature. The volatiles
purged from the sample are trapped on a solid sorbent.
They are subsequently desorbed by rapidly heating the
sorbent and then introduced into a GC/MS
system. Table 2 summarizes the preparation methods and
instruments used in this analytical service.

DATA DELIVERABLE^
Data deliverables for this service include both hardcopy
data reporting forms and supporting raw data. The
laboratory must submit data to EPA within 14 days after
laboratory receipt of the last sample in the set. EPA then
checks the data for compliance with contract requirements.
A report of instances of noncompliance is distributed to the
laboratory and the Region within 10 days from the receipt
of the data. The laboratory has 10 days to reconcile
defective data and resubmit the data to EPA. EPA then
screens the data and sends a final data assessment report to
the laboratory and the Region.
QUALITY ASSURANCE
The quality assurance (QA) process consists of
management review and oversight at the planning,
implementation, and completion stages of the
environmental data collection activity. This process
ensures that the data provided are of the quality required.
During the implementation of the data collection effort,
QA activities ensure that the quality control (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 to determine its suitability to support enforcement
or remedial decisions. Each contract laboratory prepares a
quality assurance plan (QAP) with the objective of
providing sound analytical chemical measurements. The
QAP must specify the policies, organization, objectives,
and functional guidelines, as well as the QA and QC
activities designed to achieve the data quality requirements
for this analytical service.
QUALITY CONTROL
The QC process includes those activities required during
analytical data collection to produce data of known and
documented quality. The analytical data acquired from
QC procedures are used to estimate and evaluate the
analytical results and to determine the necessity for, or the
effect, of corrective action procedures. The QC
requirements for this analytical service are shown
in Table 3.

data validator, and (if available) the Quality Assurance Project Plan (QAPP) and Sampling and Analysis Plan
(SAP).
Feasibility Study: A description and analysis of potential cleanup alternatives for a site such as one on the
National Priorities List. The feasibility study usually recommends selection of a cost-effective alternative. It
usually starts as soon as the remedial investigation is underway. Together, they are commonly referred to as
the "RI/FS".
Gas Chromatography (GC): The instrument used to separate analytes on a stationary phase within a
chromatographic column. Gas Chromatography is frequently used with other instruments for analyzing organic
compounds:
a). Mass Spectrometry. In volatile and semivolatile analysis, the compounds are detected by a Mass
Spectrometer (MS).
b). Electron Capture: In pesticide/Aroclor analysis, the compounds are detected by an Electron Capture
Detector (ECD).
Hazard Ranking System (MRS): A numerically based screening system that uses information from initial,
limited investigations to assess the relative potential of sites to pose a threat to human health or the
environment. MRS is the principal mechanism EPA uses to place uncontrolled waste sites on the National
Priorities List (NPL).
Hazardous Waste Site: A site contaminated with substances that can pose a substantial or potential hazard
to human health or the environment.
Inductively Coupled Plasma - Atomic Emission Spectroscopy (ICP-AES): A technique for the
simultaneous or sequential multi-element determination of elements in solution. The basis of the method is the
measurement of atomic emission by an optical spectroscopic technique. Characteristic atomic line emission
spectra are produced by excitation of the sample in a radio frequency inductively coupled plasma.
ILM04.1: The current inorganic analytical protocol.
National Functional Guidelines (NFG): Documents designed to offer guidance on inorganic, organic, and
organic low concentration CLP analytical data evaluation and review.
National Priorities List (NPL): A list of sites for hazardous waste cleanup under the Superfund program.
Office of Solid Waste and Emergency Response (OSWER): The EPA office that provides policy, guidance,
and direction for the EPA's solid waste and emergency response programs, including Superfund.
OLC02.1: The current organic low concentration water analytical protocol.
OLM04.2: The current organic analytical protocol.
OSCs: On-Scene Coordinators for the Superfund's Removal Program.
Performance Evaluation (PE) Sample: A sample of known composition provided by EPA for contractor
analysis. Used by EPA to evaluate contractor performance.
Pesticides: Substances intended to repel, kill, or control any species designated a "pest", including weeds,
insects, rodents, fungi, bacteria, and other organisms.
E-2
-------
Polychlorinated Biphenyls (PCBs): A group of toxic, persistent chemicals used in electrical transformers
and capacitors for insulating purposes, and in gas pipelines systems as a lubricant. The sale and new use of
PCBs were banned by law in 1979.
Quality Assurance (QA): An integrated system of management activities involving planning, implementation,
assessment, reporting, and quality improvement to ensure that a process, item, or service is of the type and
quality needed and expected by the customer.
Quality Control (QC): The overall system of technical activities that measures the attributes and performance
of a process, item, or service against defined standards to verify that they meet the stated requirements
established by the customer; operational techniques and activities that are used to fulfill requirements for
quality.
Quality Assurance Technical Support (QATS) Laboratory: A contractor-operated facility operated under
the QATS contract, awarded and administered by EPA.
Remedial Action: The construction or clean-up phase of a Superfund site cleanup.
Remedial Design: A phase of remedial action that follows the remedial investigation/feasibility study and
includes development of engineering drawings and specifications for a site cleanup.
Remedial Investigation: An in-depth study designed to gather data needed to determine the nature and
extent of contamination at a Superfund site, establish site cleanup criteria, identify preliminary alternatives for
remedial action, and support technical and cost analyses of alternatives. The remedial investigation is usually
done with the feasibility study. Together they are usually referred to as the "RI/FS".
Remedial Project Manager (RPM): The EPA or state official responsible for overseeing on-site remedial
action.
Remedial Response: Long-term action that stops or substantially reduces a release or threat of a release of
hazardous substances that is serious but not an immediate threat to public health.
Remediation: Cleanup or other methods used to remove or contain a toxic spill or hazardous materials from a
