SW-846, a methods manual, is a "living" document that changes when new data and
advances in analytical techniques are incorporated! into the manual as new or revised
methods. To date, the Agency has formally issued Final Updates I, II, IIA, IBB, and
III.  This  package  contains Final Update III A.   For  specific  and important
information regarding this update, please read the section below entitled "About
Final Update IHA."

These instructions describe how to get your basic manual up-to-date and what to do
with your Final Update IIIA package.  Additional updates will be released by the
Agency hi the future. New instructions, to supersede these, will be included with
each of those new update releases.  A number of SW-846 update packages have been
released to the public since the original Third Edition was released. The dates and
labels on these packages can be confusing. In general, final updates should always
be incorporated into SW-846 in chronological order (e.g.  Update I should be
incorporated before Update II).

The following definitions are provided to you as a guide:

      New subscribers are defined as individuals who  have recently (6-8 weeks)
      placed an order with the GPO and have received  new copies of the 4 (four)
      volume set of the Third 'Edition, a copy of Final  Update I, a copy of Final
      Update n/BLA, a copy of Final Update HE, a copy of Final Update III, a copy
      of Draft Update IVA, and  a copy of Final Update IIIA.

      Previous subscribers are defined as individuals that have received copies of
      the Third Edition and other SW-846 Updates (including proposed Updates)
      hi the past and have just received their Final Update IIIA package in the mail.

       As of Update m to SW-846, the two SW-846 methods for determination of oil and grease
were Method 9070 for waters and aqueous wastes, and Method 9071A for solid and semi-solid
materials such as soil, sediment, and sludge.  Method 9070 was virtually identical to Office of
Water methods for determination of oil and grease; and Method 9071 A employed drying of the
sample with magnesium sulfate and using Soxhlet extraction for the determination. Both methods
used l,l,2-tricnloro-l,2,2-trifluoroethane (CFC-113; Freon-113) as the extraction solvent in the
testing of samples for oil and grease levels.

       The Agency recently published a final rule in the Federal Register which finalized Office
of Water Method 1664, Revision A, and SW-846 Method 9071B and withdrew previously
approved methods  (including certain Office of Water methods and SW-846 Method 9070) for the
determination of oil and grease and non-polar material (NPM) in EPA's wastewater and hazardous
waste programs.  These changes were made as a part of EPA's effort to reduce dependency on
the use of chlorofluorocarbons (CFCs) in order to protect Earth's ozone layer and to meet the CFC
phaseout agreed to in the Montreal Protocol and required by the Clean Air Act Amendments of
 1990.  Method 1664 now uses normal hexane (n-hexane) as the extraction solvent in place of
 l,l,2-trichloro-l,2,2-trifluoroethane (CFC-113; Freon-113), a Class 1 CFC.

       As part of that final rule, SW-846 was amended to delete Method 9070 and to  include
 revised Method 9071B as Final Update mA to the manual. Specifically, Method 9071B addresses
 the use of n-hexane instead of CFC-113 as the extraction solvent, in a manner consistent with the
 use of n-hexane in Method 1664.  In addition, in place of Method 9070, which used CFC-1 13 as
 the extraction solvent in the testing of waters and aqueous wastes, the Agency incorporated by
 reference Method 1664 in the RCRA regulations. As part of Final Update mA, SW-846 refers
 the regulated community to Method 1664 for testing previously conducted using Method 9070.
 The' publication number for Method 1664 is EPA-821-R-98-002.

       Final Update IKA has been issued by the EPA's  Office of Solid Waste and  contains
 documents which have been promulgated for inclusion in the SW-846. methods manual. The Final
 Update mA package includes one revised method  (Method 9071B), one revised chapter (Chapter
 Five), a page to replace Method 9070, and a revised Table of Contents.  Method 9070  needs to
 be removed from the manual when Final Update mA is incorporated.

        The following is a brief summary of what new subscribers and previous subscribers should
 do upon receipt of the Update IDA package:
                                                                j
 NEW SUBSCRIBERS - If you are a new subscriber, you should perform the following tasks
 before addressing your new Update DIA:
                                    Instructions - 2                   Final Update

-------
    •   Place the original Third Edition of SW-846 (September 1986) in the properly labeled four
       3-ring notebooks according to the instructions in Final Update III.

   •   Incorporate Final Update I (July 1992) into the manual according to the instructions in
       Final Update m.

    •   Incorporate Final Updates H (September 1994) and HA (August 1993) into the manual
       according to the instructions in Final Update HI.

    •   Incorporate Final Update HE (January 1995) into the manual according to the instructions
       in Final Update m.

    •   Incorporate Final  Update El  (December 1996)  into  the  manual  according  to  its
       instructions.

    •   Either incorporate Draft Update IVA in the manual (without removing any white pages),
       or keep the colored draft update in a separate binder of your choice.

Finally, incorporate Final Update IQA.  Final Update IIIA is printed on white paper and has the
date of "April 1998" in the lower right hand corner of each page. This package contains revised
material for SW-846, specifically a revised Table of Contents, Chapter Five, and Method 9071B.
In addition, it contains a page that should be used to replace Method 9070. Remove Method 9070
from the manual. This method has been deleted from SW-846 as part of Final Update IIIA.
Then, use  the Table of Contents dated April 1998 to determine the correct  location  for each
document in the Final Update IDA package.'

PREVIOUS SUBSCRIBERS - If you are a previous  subscriber, it is important to  establish
exactly what is currently contained in your manual before addressing Final Update IIIA. If your
manual is properly updated, the ONLY white pages in  the document should be dated September
'1986 (Third Edition), July 1992 (Final Update I), August 1993 (Final Update IIA), September
 1994 (Final Update JJ), January 1995 ([Final Update IIB), and December 1996 (Final Update III).
Remove (and recycle  or archive) any white pages from your manual that have any other dates.
There may also be colored pages (e.g.,  pink pages for Proposed Update III) inserted in the
manual. Remove all yellow, blue, green, or pink pages from the manual.  These colored pages
represent proposed versions of methods  and chapters that have since been finalized. (Some
individuals may chose to,keep their  copies of colored versions in separate binders.) You may keep
your Draft Update IVA pages in the manual if you wish -- that update has not yet been finalized.
Follow the last paragraph in the instructions for new subscribers to determine how to incorporate
Final Update IIIA. The table below can be used as an  aide to determine what should be in your
manual.

n-HEXANE EXTRACTABLE MATERIAL. fHEM^ FOR SLUDGE. SEDIMENT. AND SOLID SAMPLES


1.0  SCOPE AND APPLICATION    ,    •             •    ;

     1.1    Method 9071 may be used to quantify low concentrations of oil and grease in soil,
sediments, sludges, and other solid materials amenable to chemical drying and solvent extraction
with n-hexane.   "Oil and grease" is a conventional pollutant under 40 CFR 401.16 and generally
refers to substances, including biological lipids and mineral hydrocarbons, that have similar physical
characteristics and common solubility in an organic extracting solvent. As such, oil and grease is
an operationally defined parameter, and the results will depend entirely on the extracting solvent and
method of extraction.   Method 9071 employs n-hexane as the extraction solvent with Soxhlet
extraction and the results of this method are appropriately termed "n-hexane extractable material
(HEM)." Section 1.2 lists the type of materials that may be extracted by this method.  In the context
of this method, "HEM" is used throughout this method and for operational purposes, may  be
considered synonymous with "oil and grease" within the limitations discussed below.

     1.2    Specifically, Method 9071 is suitable for extracting relatively non-volatile hydrocarbons,
vegetable oils, animal fats, waxes, soaps, greases,  biological lipids, and related materials.

     1.3    Method  9071 is  not  recommended for  measuring  materials that volatilize  at
temperatures below 85°C. Petroleum fuels from gasoline through #2 fuel oil may be partially lost
during the solvent removal process.

     1.4     Some crude oils  and heavy fuel oils may  contain materials that are not soluble in
n-hexane, and recovery of these materials may be low.      ;


2.0  SUMMARY OF METHOD

     2.1    A representative portion of wet (as received) waste is acidified with concentrated HCI
and chemically dried with magnesium sulfate or sodium sulfate.  Magnesium sulfate monohydrate
is used to dry acidified sludges as it will combine with 75% of its own weight in water in forming
MgSO4 • 7H2O.  Anhydrous sodium sulfate is used to dry soil and sediment samples.

     2.2    After drying, the HEM  is extracted with n-hexane using a Soxhlet apparatus. The
n-hexane extract is then distilled from the extract and the HEM is desiccated and weighed.

      2.3    When necessary, a separate sample portion is evaluated for percent solids, and the
dry weight fraction may be used to calculate the dry-weight HEM concentration of the soil, sediment,
or waste.
 3.0   DEFINITIONS    '                                 ;

      3.1    n-Hexane extractable material (HEM, oil and grease):  Material that is extracted from
 a sample using n-hexane and determined  by this method. This material includes relatively non-
 volatile hydrocarbons, vegetable oils, animal fats, waxes, soaps, greases, and related matter.

      3:2    Refer to Chapter One for additional definitions. ,

                                                       :                       April 1998

4.0   INTERFERENCES

      4.1     This method is entirely empirical, and  duplicate  results having a high degree of
precision can be obtained only by strict adherence to all details. The rate of cycling and time of
extraction in the Soxhlet apparatus must be consistent and length of time required for drying and
cooling extracted materials must be the same in order to generate consistent results. It is important
that the procedures be performed as directed due to the varying solubilities of the different greases
and heavy mineral oils.

      4.2    Solvents, reagents, glassware, and other sample-processing hardware may yield
artifacts that could affect the results.  All solvents and reagents used in the analysis should be
demonstrated to be free from interferences by processing a method blank with each analytical batch.
Specific selection of reagents, solvent washes, or purification of solvents may be required. Use of
plastic measuring devices, and/or plastic tubing attachments must be avoided.

      4.3    Glassware should be cleaned by washing with hot tap water with detergent, rinsing with
tap water and reagent water, and rinsing with solvent. Glassware may also be baked at 200-250 °C
for 1  hour. Boiling flasks that are used to  contain the  extracted residues may be dried in an oven
at  105-115°C and stored  in a desiccator  until used.  Depending  on the project  DQOs,  strict
adherence to the washing and handling procedures cited above may not be necessary as long as
the laboratory can demonstrate that alternative  cleaning procedures yield acceptable method
performance and meet method blank acceptance criteria.

      4.4    A gradual increase in weight may result due to the absorption of oxygen; a gradual loss
of weight may result due to volatilization.  Extracted residues should be maintained in a desiccator
during cooling and prior to weighing.   Extracted residues should be weighed as soon as possible
after cooling.

      4.5    The presence of non-oily extractable substance such as sulfur compounds, organic
dyes, and chlorophyll, may result in a positive bias. For the purpose of this method, all materials
extracted and retained during this procedure'are defined as HEM.


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 chemicals should be reduced to the lowest possible level. It is suggested that the
 laboratory perform personal hygiene monitoring of  each analyst that uses this method. This
 monitoring should be performed using Occupational Safety and Health Administration (OSHA) or
 National Institute of Occupational Safety and Health (NIOSH) approved personal hygiene monitoring
 methods. Results of this monitoring should be made available to the analyst.

      5.2    n-Hexane has been shown to have increased neurotoxic effects over other hexanes
 and some other solvents.  OSHA has proposed a time-weighted average (TWA) of  50 parts-per-
 million (ppm); NIOSH concurs that an 8-hour TWA/permissible exposure limit (PEL) of 50 ppm is
 appropriate for n-hexane; and the American  Conference  of Governmental Industrial Hygienists
 (ACGIH) has published a threshold limit value (TLV) of 50 ppm for n-hexanel Inhalation of n-hexane
 should be minimized by performing all operations with n-hexane in a explosion-proof hood or well-
 ventilated area.
                                        9071B-2
Revision 2

-------
     5.3    n-Hexane has a flash point of -23 °C (-9°F), has explosive limits in air in the range of
1 to 7 percent, and poses a serious fire risk when heated or exposed to flame. n-Hexane can react
vigorously with oxidizing materials. The laboratory should include procedures in its operations that
address the safe handling of n-hexane.

     5.4    Unknown samples may contain high concentrations of volatile toxic compounds.
Sample containers should be opened in a hood and handled with gloves to prevent exposure.

     5.5    This method does not address all safety issues associated with its use. The laboratory
is responsible for maintaining a safe work environment and a current awareness file of OSHA
regulations regarding the safe handling of the chemicals specified in this method.  A reference file
of material safety data sheets (MSDSs) should be available to all personnel involved in these
analyses.

8.0  SAMPLE COLLECTION, PRESERVATION, AND STORAGE

     8.1    A minimum of 100 grams of sample should be collected using a metal spatula, spoon,
or equivalent device. Samples should be collected into a pre-cleaned wide-mouth glass container
fitted with a TFE-lined screw cap.
                                 i
     8.2    When practical (i.e., when the sample matrix allows the complete mixing of sample and
acid such as with a pourable sludge or sediment), the sample should be preserved to a pH < 2 by
adding 1 mL of concentrated HCI per 100 gram of sample and cooled to 4 ± 2 °C. If acidification is
not practical (as with a dry soil), the addition of the HCI is not required and the sample should be
cooled to 4 ± 2 °C. The laboratory must be notified so that the sample can be acidified prior to
analysis.

     8.3    A holding time has not been established for HEM in solids, but it is recommended  that
the sample be analyzed as soon as possible.


9.0  QUALITY CONTROL

     9.1    Each laboratory that uses this method is required to operate a formal quality control
program. The minimum requirements of this program consist of an initial demonstration of laboratory
capability and the analysis of spiked samples as a continuing check on performance.  The laboratory
is required to maintain performance records to define the quality of data that is generated.

     9.2    Employ a minimum, of one method blank per analytical batch or twenty samples,
whichever is more frequent, to verify that all reagents, solvents, and equipment are contamination
free. Prepare the method blank from 5 g of inert matrix such as pre-deaned sand or similar material,
and carry it through the analytical process.

     9.3    Run one matrix duplicate and matrix spike sample every twenty samples or analytical
batch, whichever is more frequent. Matrix duplicates and spikes are brought through the whole
sample preparation and analytical process.

     9.4    The performance of the method should be evaluated by the use of a Laboratory Control
Sample (LCS).  The LCS is prepared by spiking an inert matrix (as pre-cleaned sand or similar
material) with an appropriate volume of spiking solution  (Sec. 7.7) and  carrying it through the
analytical process.                                   .   :


10.0 CALIBRATION AND STANDARDIZATION

     10.1   Calibrate the analytical balance at 2 mg and 1000 mg using class "S" weights.

     10.2   Calibration shall be within ± 10% (i.e.,  ± 0,2 mg) at 2 mg and ± 0.5 % (i.e., ± 5 mg) at
1000 mg. If values are not within these limits, recalibrate the: balance.

            11.1.1   When it is necessary to report the HEM on a dry weight basis, determine the
    ' dry weight fraction using a separate aliquot of sample, as discussed below.  The aliquot used
     for this determination cannot be used to evaluate HEM.

            11.1.2   Weigh 5-10 gram (±  0.01 gram) of the sample into pre-weighed crucible.
     Determine the weight of the wet sample by subtracting the weight of the crucible.

            11.1.3   Place the crucible  with the wet sample in an oven overnight at 105°C.
     Remove crucible from oven and place in a desiccator to cool. Weigh.  Determine dry weight
     of sample by subtracting the weight of the crucible.   Determine the dry weight fraction of the
     sample as follows:

            NOTE:  The drying oven should be contained in  a hood or vented.  Significant
                    laboratory contamination may result from a heavily contaminated hazardous
                    waste sample.
                                                                   i

            11.2.1   Sludge/Waste Samples

                    11.2.1.1   Weigh out 20 ± 0.5 grams of wet sample into a 150-mL beaker.

                    11.2.1.2   If the sample has not been acidified, acidify to a pH <; 2 with
            approximately 0.3 ml_ concentrated HCI.

                    11.2.1.3   Add 25 grams Mg2SO4 • H2O (Sec. 7.4) and stir to a smooth
            paste.

                    11.2.1.4   Spread paste on sides of beaker to facilitate evaporation.  Let
            stand about 15-30 min or until material is solidified.
              :                            i                         I          .        '
                    11.2.1.5   Remove solids and grind to fine powder in a mortar.

                    11.2.1.6   Add the powder to the paper extraction thimble.

                    11.2.1.7   Wipe beaker and mortar with pieces of filter paper moistened with
            n-hexane and add to thimble.

                    11.2.1.8   Fill thimble with glass wool (or glass beads).
                                        9071B - 6                              Revision 2
                                                                              April 1998

-------
       11.2.2   Sediment/Soil Samples

               11.2.2.1    Decant and discard any water layer on a sediment sample. Mix
       sample thoroughly, especially composited samples.  Discard any foreign objects such
       as sticks, leaves, and rocks.

               11.2.2.2    Blend 10 grams of the sample with 10 grams of anhydrous sodium
       sulfate (Sec. 7.5) as described in Section 11.2.1. Transfer homogenized paste to an
       extraction thimble and cover with glass wool or glass beads. The extraction thimble
       must drain freely for the duration of the extraction period.

11.3   Extraction

       11.3.1   Set-up the Soxhlet apparatus containing the extraction thimble and sample
and attach a 125-mL boiling flask containing 90 mL of n-hexane. Add boiling chips. Adjust the
heating control on the heating mantle so that a cycling rate of  20 cycles/h is obtained. Extract
for a period of 4 hrs.

       11.3.2   Tare a clean 250-mL or appropriate sized boiling flask as follows:

               11.3.2.1    Dry the flask in an oven at 105-115°C for a minimum of 2 h.

               11.3.2.2    Remove from the oven and immediately transfer to a desiccator
       to cool at room temperature.

               11.3.2.3   When cool, remove from the desiccator with tongs and  weigh
       immediately on a calibrated balance.

       11.3.3   At the end of the 4 h extraction period, filter the extract through grease-free
cotton, into the pre-weighed boiling flask (Sec. 11.3.2). Use gloves to avoid adding fingerprints
to the flask.

       11.3.4  Rinse flask and cotton with n-hexane and add to the 250-mL boiling flask.

       NOTE:  If the extract is clear and no suspended particles are present, the filtration
               Step may be omitted.

       11.3.5  Connect the boiling flask to the distilling head apparatus and distill the solvent
by immersing the lower half of the flask in a water bath or a steam bath.  A heating mantle may
also be used. Adjust the temperature of the heating device to complete the distillation in less
than 30 minutes.  Collect the solvent for reuse or appropriate disposal.

       11.3.6  When the distillation is complete, remove the distilling head.  Immediately
remove the flask from the heat source and wipe the outside to remove excess moisture and
fingerprints. To remove solvent vapor, sweep out  the flask for 15 sec with air by inserting a
glass tube that is connected to a vacuum source.

       11.3.7  Cool the boiling flask in a desiccator for 30 min  and weigh. Determine the
gain in weight of the boiling flask by subtracting the weight of the boiling flask (Sec.  11.3.2)
from the final boiling flask weight.

13.0 METHOD PERFORMANCE

     In a preliminary study designed to find a suitable replacement for F:reon-113, three EPA
contract laboratories evaluated  a total of 28 solid  samples derived from various industrial and
commercial processes for oil and grease.  This study evaluated a total of six solvents, including n-
hexane, to determine which of the alternative solvents produced results most closely with that of
Freon-113.  In tfiis study, each waste was Soxhlet-extractecl in triplicate using Freon-113 and each
of the  alternative solvents. Based on the overall results, n-hexane was judged to  be the best
alternative solvent. The data provided in Table i compare the results for Freon-113 and n-hexane
for each waste. For a complete discussion of this study, refer to reference 1 in Section 16.0.


14.0 POLLUTION PREVENTION

     14.1   Pollution prevention encompasses any technique that reduces or eliminates the quantity
and/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

     The Environmental Protection Agency requires that laboratory waste management practices
be conducted consistent with all applicable Federal, state and  local rules and regulations.  The
Agency urges laboratories to protect the air, water,  and land  by minimizing  and controlling all
