Cover sheet. (What you are currently reading) 2. Instructions. This section explains how Proposed Update IIIB relates to the rest of SW-846. 3. Status Tables. The "Status Tables" document includes two tables. One table is a sequentially numbered listing of all SW-846 methods and their current status. The other table lists the status of all other documents in SW-846 (e.g., the Disclaimer, the chapters). 4. Proposed Update IIIB Table of Contents. The Table of Contents (dated August 2002) lists all of the methods (as updated by Third Edition Final Updates I, II, IIA, IIB, III, and IIIA and Proposed Update IIIB) in the order of appearance in the manual. It does not reflect Draft Update IVA or B methods because the Agency plans to publish Final Update IIIB before the final versions of the Draft Update IVA or B methods. 5. Revised Chapter Five and revised Methods 9010C. 9012B. 9060A. and 9070A. 6. Revised Chapter Six and revised Methods 9045D and 9095B. 7. Revised Chapter Seven 8. Revised Chapter Eight and revised Methods 1010A. 1020B. 9040C. 1110A. and 1310B ------- INSTRUCTIONS 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, n, HA, DB, and ffl, fflA, and Draft Updates IV A and IVB. (Currently, the methods and chapters of Final Update IDA and Draft Update IVB are not available from GPO, but are available on-line at www.epa.gov/SW-846/ or on paper from NTIS, (800) 553-6847.) This package contains Proposed Update These instructions describe how to get your basic manual up-to-date and what to do with your Proposed Update LLLB package. 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 IT). If you got your package from GPO, the following definitions are provided as they relate to the text to follow regarding how to put together a GPO subscription to SW-846: Previous subscribers are defined as individuals that have received copies of the Third Edition and other SW-846 updates (including proposed updates) in the past and have just received only this Proposed Update nffi package in the mail. 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/HA, a copy of Final Update HE, a copy of Final Update HI, a copy of Draft Update FVA, and a copy of this Proposed Update Instructions - 1 Proposed Update EHB August 2002 ------- INCORPORATING PROPOSED UPDATE IIIB IN YOUR MANUAL Proposed Update TTTR is printed on buff colored paper and has the date of "August 2002" in the lower right hand corner of each page. This package contains revised material proposed for addition to SW-846. Because it is a proposed update and not yet final, its proposed methods cannot yet be used for compliance with required uses of SW-846 methods in the RCRA regulations. You may have gotten this package from the National Technical Information Service (NTIS) or the Government Printing Office (GPO). Please visit the EPA OSW Methods Team website at http://www.epa.gov/SW-846/ for information on other ways to obtain SW-846 methods and updates. Please note that, if you wish to keep all of the final, proposed, and draft updates together, you may find that the binders provided to you as part of a GPO subscription are not large enough to contain all of the material. In that case, you should augment the manual with other binders of your choice. The instructions below can be generally followed as appropriate if you get your SW-846 from other sources besides GPO. NEW GPO SUBSCRIBERS - If you are a new subscriber, you should perform the following tasks before addressing your Proposed Update HIB (those who obtained their manual from other sources, may also find this information useful in putting it together): 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 D3. Incorporate Final Update I (July 1992) into the manual according to the instructions in Final Update m. Incorporate Final Updates n (September 1994) and HA (August 1993) into the manual according to the instructions in Final Update ID. Incorporate Final Update IIB (January 1995) into the manual according to the instructions in Final Update IJJ. Incorporate Final Update HI (December 1996) into the manual according to its instructions. Either incorporate Draft Update IV A in the manual (without removing any white pages), or keep the colored draft update in a separate binder of your choice. Finally, incorporate Proposed Update HIB into the manual without removing any white pages, or keep the colored proposed update in a separate binder of your choice. Instructions - 2 Proposed Update HIB August 2002 ------- PREVIOUS GPO SUBSCRIBERS - If you are a previous subscriber, it is important to establish exactly what is currently contained in your manual before addressing Proposed Update fflB. 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 HA), September 1994 (Final Update n), January 1995 (Final Update UB), December 1996 (Final Update HI), and April 1998 (if you have added Final Update UIA from NTIS or the EPA OSW Methods web site). 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 HI) 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. You may chose to keep your copies of colored versions in separate binders. You may keep proposed or draft update pages in the manual if you wish, but those methods are not promulgated final methods and thus cannot be used for required uses of SW-846 methods in the RCRA regulations. Finally, incorporate Proposed Update fflB into the manual without removing any white pages, or keep the colored proposed update in a separate binder of your choice.

It is based on the decomposition of nearly all cyanides by a reflux distillation procedure using a strong acid and a magnesium catalyst. Cyanide, in the form of hydrocyanic acid (HCN) is purged from the sample and captured into an alkaline scrubber solution. The concentration of cyanide in the scrubber solution is then determined by Method 9014 or Method 9213. Method 9010 may be used as a reflux-distillation procedure for both total cyanide and cyanide amenable to chlorination. The "reactive" cyanide content of a waste is notdetermined by this method. Refer to 40 CFR 261.23 for information on the characteristic of reactivity. 1.2 This method was designed to address the problem of "trace" analyses (<1000 ppm). The method may also be used for "minor" (1000 ppm -10,000 ppm) and "major" (>10,000 ppm) analyses by adapting the appropriate sample dilution. However, the amount of sodium hydroxide in the standards and the sample analyzed must be the same. 2.0 SUMMARY OF METHOD 2.1 The cyanide, as hydrocyanic acid (HCN), is released from samples containing cyanide by means of a reflux-distillation operation under acidic conditions and absorbed in a scrubber containing sodium hydroxide solution. The cyanide concentration in the absorbing solution is then determined colorimetrically ortitrametrically by Method 9014 or by ion-selective electrode by Method 9213. 3.0 INTERFERENCES 3.1 Interferences are eliminated or reduced by using the distillation procedure. Chlorine and sulfide are interferences in Method 9010. 3.2 Oxidizing agents such as chlorine decompose most cyanides. Chlorine interferences can be removed by adding an excess of sodium arsenite to the waste prior to preservation and storage of the sample to reduce the chlorine to chloride which does not interfere. 3.3 Sulfide interference can be removed by adding an excess of bismuth nitrate to the waste (to precipitate the sulfide) before distillation. Samples that contain hydrogen sulfide, metal sulfides, or other compounds that may produce hydrogen sulfide during the distillation should be treated by the addition of bismuth nitrate. 3.4 High results may be obtained for samples that contain nitrate and/or nitrite. During the distillation, nitrate and nitrite will form nitrous acid, which will react with some organic compounds to form oximes. These compounds once formed will decompose under test conditions to generate HCN. The possibility of interference of nitrate and nitrite is eliminated by pretreatment with sulfami acid just before distillation. Nitrate and nitrite are interferences when present at levels higher than 10 mg/L and in conjunction with certain organic compounds. 9010C-1 Revision 3 August 2002 ------- 3.5 Thiocyanate is reported to be an interference when present at very high levels. Levels of 10 mg/L were not found to interfere. 3.6 .Fatty acids, detergents, surfactants, and other compounds may cause foaming during the distillation when they are present in high concentrations and may make the endpoint for the titrimetric determination difficult to detect. Refer to Sec. 6.8 for an extraction procedure to eliminate this interference. 4.0 APPARATUS AND MATERIALS 4.1 Reflux distillation apparatus such as shown in Figure 1 or Figure 2. The boiling flask should be of one liter size with inlet tube and provision for condenser. The gas scrubber may be a 270-mL Fisher-Milligan scrubber (Fisher, Part No. 07-513) or equivalent.

All containers must be thoroughly cleaned and rinsed. 6.2 Oxidizing agents such as chlorine decompose most cyanides. To determine whether oxidizing agents are present, test a drop of the sample with potassium iodide-starch test paper. A blue color indicates the need for treatment. Add 0.1N sodium arsenite solution a few mL at a time until a drop of sample produces no color on the, indicator paper. Add an additional 5 mL of sodium arsenite solution for each liter of sample. Ascorbic acid can be used as an alternative although it 901OC-3 Revision 3 August 2002 ------- is not as effective as arsenite. Add a few crystals of ascorbic acid at a time until a drop of sample produces no color on the indicator paper. Then add an additional 0.6 g of ascorbic acid for each liter of sample volume. 6.3 Aqueous samples must be preserved by adding 50% sodium hydroxide until the pH is greater than or equal to 12 at the time of collection. 6.4 Samples should be chilled to 4ฐC. 6.5 When properly preserved, cyanide samples can be stored for up to 14 days prior to sample preparation steps. 6.6 Solid and oily wastes may be extracted prior to analysis by method 9013. It uses a dilute NaOH solution (pH = 12) as the extractant. This yields extractable cyanide. 6.7 If fatty acids, detergents, and surfactants are a problem, they may be extracted using the following procedure. Acidify the sample with acetic acid (1.6M) to pH 6.0 to 7.0. CAUTION: This procedure can produce lethal HCN gas. Extract with isooctane, hexane, or chloroform (preference in order named) with solvent volume equal to 20% of the sample volume. One extraction is usually adequate to reduce the compounds below the interference level. Avoid multiple extractions or a long contact time at low pH in order to keep the loss of HCN at a minimum. When the extraction is completed, immediately raise the pH of the sample to above 12 with 50% NaOH solution. 7.0 PROCEDURE 7.1 Pretreatment for cyanides amenable to chlorination 7.1.1 This test must be performed under amber light. K3[Fe-(CN)6] may decompose under UV light and hence will test positive for cyanide amenable to chlorination if exposed to fluorescent lighting or sunlight. Two identical sample aliquots are required to determine cyanides amenable to chlorination. 7.1.2 To one 500 ml sample or to a sample diluted to 500 ml, add calcium hypochlorite solution dropwise while agitating and maintaining the pH between 11 and 12 with 1.25N sodium hydroxide until an excess of chlorine is present as indicated by Kl-starch paper turning blue. The sample will be subjected to alkaline chlorination by this step. CAUTION: The initial reaction product of alkaline chlorination is the very toxic gas cyanogen chloride; therefore, it is necessary that this reaction be performed in a hood. 7.1.3 Test for excess chlorine with Kl-starch paper and maintain this excess for one hour with continuous agitation. A distinct blue color on the test paper indicates a sufficient chlorine level. If necessary, add additional calcium hypochlorite solution. 7.1.4 After one hour, add 1 mL portions of 0.1 N sodium arsenite until Kl-starch paper shows no residual chlorine. Add 5 ml of excess sodium arsenite to ensure the presence of excess reducing agent. 901OC-4 Revision 3 August 2002 ------- 7.1.5 Analyze the total cyanide concentration of both the chlorinated and the unchlorinated samples by Method 9014 or 9213. The difference between the total cyanide concentration in the chlorinated and unchlorinated samples is equal to the cyanide amenable to chlorination. 7.2 Distillation procedure 7.2.1 Place 500 mL of sample, or sample diluted to 500 ml in the one liter boiling flask. Pipet 50 mL of 1.25N sodium hydroxide into the gas scrubber. If the apparatus in Figure 1 is used, add water until the spiral is covered. Connect the boiling flask, condenser, gas scrubber and vacuum trap. 7.2.2 Start a slow stream of air entering the boiling flask by adjusting the vacuum source. Adjust the vacuum so that approximately two bubbles of air per second enter the boiling flask through the air inlet tube. 7.2.3 If samples are known or suspected to contain sulfide, add 50 mL of 0.062M bismuth nitrate solution through the air inlet tube. Mix for three minutes. Use lead acetate paper to check the sample for the presence of sulfide. A positive test is indicated by a black color on the paper. 7.2.4 If samples are known or suspected to contain nitrate or nitrite, or if bismuth nitrate was added to the sample, add 50 mL of 0.4N sulfamic acid solution through the air inlet tube. Mix for three minutes. NOTE: Excessive use of sulfamic acid could create method bias. 7.2.5 Slowly add 50 mL of 18N sulfuric acid through the air inlet tube. Rinse the tube with water and allow the airflow to mix the flask contents for three minutes. Add 20 mL of 2.5M magnesium chloride through the air inlet and wash the inlet tube with a stream of water. 7.2.6 Heat the solution to boiling. Reflux for one hour. Turn off heat and continue the airflow for at least 15 minutes. After cooling the boiling flask, and closing the vacuum source, disconnect the gas scrubber. 7.2.7 Transfer the solution from the scrubber into a 250-mL volumetric flask. Rinse the scrubber into the volumetric flask. Dilute to volume with water. 7.2.8 Proceed to the cyanide determinative methods given in Methods 9014 or 9213. If the distillates are not analyzed immediately, they should be stored at 4ฐC in tightly sealed flasks. 8.0 QUALITY CONTROL 8.1 All quality control data should be maintained and available for easy reference or inspection. 8.2 Employ a minimum of one reagent blank per analytical batch or one in every 20 samples to determine if contamination or any memory effects are occurring. 8.3 Analyze check standards with every analytical batch of samples. If the standards are not within 15% of the expected value, then the samples must be reanalyzed. 901OC-5 Revision 3 August 2002 ------- 8.4 Run one replicate sample for every 20 samples. A replicate sample is a sample brought through the entire sample preparation and analytical process. The CV of the replicates should be 20% or less. If this criterion is not met, the samples should be reanalyzed. 8.5 Run one matrix spiked sample every 20 samples to check the efficiency of sample distillation by adding cyanide from the working standard or intermediate standard to 500 ml of sample to ensure a concentration of approximately 40 ug/L. The matrix spiked sample is brought through the entire sample preparation and analytical process. 8.6 It is recommended that at least two standards (a high and a low) be distilled and compared to similar values on the curve to ensure that the distillation technique is reliable. If distilled standards do not agree within +10% of the undistilled standards, the analyst should find the cause of the apparent error before proceeding. 8.7 The method of standard additions shall be used for the analysis of all samples that suffer from matrix interferences such as samples which contain sulfides. 9.0 METHOD PERFORMANCE 9.1 The titration procedure using silver nitrate is used for measuring concentrations of cyanide exceeding 0.1 mg/L. The colorimetric procedure is used for concentrations below 1 mg/L of cyanide and is sensitive to about 0.02 mg/L. 9.2 EPA Method 335.2 (sample distillation with titration) reports that in a single laboratory using mixed industrial and domestic waste samples at concentrations of 0.06 to 0.62 mg/L CN', the standard deviations for precision were + 0.005 to + 0.094, respectively. In a single laboratory using mixed industrial and domestic waste samples at concentrations of 0.28 and 0.62 mg/L CN", recoveries (accuracy) were 85% and 102%, respectively. 9.3 In two additional studies using surface water, ground water, and landfill leachate samples, the titration procedure was further evaluated. The concentration range used in these studies was 0.5 to 10 mg/L cyanide. The detection limit was found to be 0.2 mg/L for both total and amenable cyanide determinations. The precision (CV) was 6.9 and 2.6 for total cyanide determinations and 18.6 and 9.1 for amenable cyanide determinations. The mean recoveries were 94% and 98.9% for total cyanide, and 86.7% and 97.4% for amenable cyanide. 10.0 REFERENCES 1. 1985 Annual Book of ASTM Standards.

WITH OFF-LINE DISTILLATION) 1.0 SCOPE AND APPLICATION 1.1 Method 9012 is used to determine the concentration of inorganic cyanide (CAS Registry Number 57-12-5) in wastes or leachate. The method detects inorganic cyanides that are present as either soluble salts or complexes. It is used to determine values for both total cyanide and cyanide amenable to chlorination. The "reactive" cyanide content of a waste is not determined by this method. Refer to 40 CFR 261.23 for information on the characteristic of reactivity. 2.0 SUMMARY OF METHOD 2.1 The cyanide, as hydrocyanic acid (HCN), is released from samples containing cyanide by means of a reflux-distillation operation under acidic conditions and absorbed in a scrubber containing sodium hydroxide solution. The cyanide ion in the absorbing solution is then determined by automated UV colorimetry. 2.2 In the automated colorimetric measurement, the cyanide is converted to cyanogen chloride (CNCI) by reaction with Chloramine-T at a pH less than 8 without hydrolyzing to the cyanate. After the reaction is complete, color is formed on the addition of pyridine-barbituric acid reagent. The concentration of NaOH must be the same in the standards, the scrubber solutions, and any dilution of the original scrubber solution to obtain colors of comparable intensity. 3.0 INTERFERENCES 3.1 Interferences are eliminated or reduced by using the distillation procedure. Chlorine and sulfide are interferences in Method 9012. 3.2 Oxidizing agents such as chlorine decompose most cyanides. Chlorine interferences can be removed by adding an excess of sodium arsenite to the waste prior to preservation and storage of the sample to reduce the chlorine to chloride which does not interfere. 3.3 Sulfide interference can be removed by adding an excess of bismuth nitrate to the waste (to precipitate the sulfide) before distillation. Samples that contain hydrogen sulfide, metal sulfides, or other compounds that may produce hydrogen sulfide during the distillation should be treated by the addition of bismuth nitrate. 3.4 High results may be obtained for samples that contain nitrate and/or nitrite. During the distillation, nitrate and nitrite will form nitrous acid, which will react with some organic compounds to form oximes. These compounds once formed will decompose under test conditions to generate HCN. The possibility of interference of nitrate and nitrite is eliminated by pretreatmentwith sulfami acid just before distillation. Nitrate and nitrite are interferences when present at levels higher than 10 mg/L and in conjunction with certain organic compounds. 3.5 Thiocyanate is reported to be an interference when present at very high levels. Levels of 10 mg/L were not found to interfere in Method 9010. 9012B-1 Revision 2 August 2002 ------- 3.6 Fatty acids, detergents, surfactants, and other compounds may cause foaming during the distillation when they are present in large concentrations and will make the endpoint of the titration difficult to detect. They may be extracted at pH 6-7. 4.0 APPARATUS AND MATERIALS 4.1 Reflux distillation apparatus such as shown in Figure 1 or Figure 2. The boiling flask should be of one liter size with inlet tube and provision for condenser. The gas scrubber may be a 270-mL Fisher-Milligan scrubber (Fisher, Part No. 07-513 or equivalent). The reflux apparatus may be a Wheaton 377160 distillation unit or equivalent. 4.2 Automated continuous-flow analytical instrument with: 4.2.1 Sampler. 4.2.2 Manifold. 4.2.3 Proportioning pump. 4.2.4 Heating bath with distillation coil. 4.2.5 Distillation head. 4.2.6 Colorimeter equipped with a 15-mm flowcell and 570 nm filter. 4.2.7 Recorder. 4.3 Hot plate stirrer/heating mantle. 4.4 pH meter. 4.5 Amber light. 4.6 Vacuum source. 4.7 Refrigerator. 4.8 5 ml microburette. 4.9 7 Class A volumetric flasks -100 and 250 ml. 4.10 Erlenmeyer flask - 500 ml. 5.0 REAGENTS 5.1 Reagent grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Chemical Society, where such specifications are available. Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination. 9012B-2 Revision 2 August 2002 ------- 5.2 Reagent water. All references to water in this method refer to reagent water, as defined in Chapter One. 5.3 Reagents for sample collection, preservation, and handling 5.3.1 Sodium arsenite (0.1N), NaAsO2. Dissolve 3.2 g NaAsO2 in 250 mL water. 5.3.2 Ascorbic acid, C6H8O6. 5.3.3 Sodium hydroxide solution (50%), NaOH. Commercially available. 5.3.4 Acetic acid (1.6M) CH3COOH.

See Sec. 5.3.1. 5.4.4 Potassium iodide starch paper. 5.5 Reagents for distillation 5.5.1 Sodium hydroxide (1.25N). See Sec. 5.4.2. 5.5.2 Bismuth nitrate (0.062M), Bi(NO)3 5H2O. Dissolve 30 g Bi(NO)3ป 5H2O in 100 mL of water. While stirring, add 250 mL of glacial acetic acid, CH3COOH. Stir until dissolved and dilute to 1 liter with water. 5.5.3 Sulfamicacid (0.4N), H2NSO3H. Dissolve 40 g H2NSO3H in 1 liter of water. 5.5.4 Sulfuricacid(18N), H2SO4.

Dissolve 510 g of MgCI2 6H2O in 1 liter of water. 5.5.6 Lead acetate paper. 5.6 Reagents for automated colorimetric determination 9012B-3 Revision 2 August 2002 ------- 5.6.1 Pyridine-barbituric acid reagent: Place 15 g of barbituric acid in a250-mL volumetric flask, add just enough reagent water to wash the sides of the flask, and wet the barbituric acid. Add 75 ml of pyridine and mix. Add 15 ml of concentrated HCI, mix, and cool to room temperature. Dilute to 250 ml with reagent water and mix. This reagent is stable for approximately six months if stored in a cool, dark place. 5.6.2 Chloramine-T solution: Dissolve 2.0 g of white, water soluble chloramine-T in 500 mL of reagent water and refrigerate until ready to use. 5.6.3 Sodium hydroxide, 1 N: Dissolve 40 g of NaOH in reagent water, and dilute to 1 liter. 5.6.4 All working standards should contain 2 ml of 1 N NaOH (Sec. 5.6.3) per 100 ml. 5.6.5 Dilution water and receptacle wash water (NaOH, 0.25 N): Dissolve 10.0 g NaOH in 500 ml of reagent water. Dilute to 1 liter. 6.0 SAMPLE COLLECTION, PRESERVATION, AND HANDLING 6.1 Samples should be collected in plastic or glass containers. All containers must be thoroughly cleaned and rinsed. 6.2 Oxidizing agents such as chlorine decompose most cyanides. To determine whether oxidizing agents are present, test a drop of the sample with potassium iodide-starch test paper. A blue color indicates the need for treatment. Add 0.1 N sodium arsenite solution a few mL at a time until a drop of sample produces no color on the indicator paper. Add an additional 5 mL of sodium arsenite solution for each liter of sample. Ascorbic acid can be used as an alternative although it is not as effective as arsenite. Add a few crystals of ascorbic acid at a time until a drop of sample produces no color on the indicator paper. Then add an additional 0.6 g of ascorbic acid for each liter of sample volume. 6.3 Aqueous samples must be preserved by adding 50% sodium hydroxide until the pH is greater than or equal to 12 at the time of collection. 6.4 Samples should be chilled to 4ฐC. 6.5 When properly preserved, cyanide samples can be stored for up to 14 days prior to sample preparation steps. 6.6 Solid and oily wastes may be extracted prior to analysis by Method 9013 (Cyanide Extraction Procedure for Solids and Oils). It uses a dilute NaOH solution (pH = 12) as the extractant. This yields extractable cyanide. 6.7 If fatty acids, detergents, and surfactants are a problem, they may be extracted using the following procedure. Acidify the sample with acetic acid (1.6M) to pH 6.0 to 7.0. CAUTION: This procedure can produce lethal HCN gas. Extract with isooctane, hexane, or chloroform (preference in order named) with solvent volume equal to 20% of the sample volume. One extraction is usually adequate to reduce the compounds below the interference level. Avoid multiple extractions or a long contact time at low pH in order to 9012B-4 Revision 2 August 2002 ------- keep the loss of HCN at a minimum. When the extraction is completed, immediately raise the pH of the sample to above 12 with 50% NaOH solution. 7.0 PROCEDURE 7.1 Pretreatment for cyanides amenable to chlorination 7.1.1 This test must be performed under amber light. K3[Fe-(CN)6] may decompose under UV light and hence will test positive for cyanide amenable to chlorination if exposed to fluorescent lighting or sunlight. Two identical sample aliquots are required to determine cyanides amenable to chlorination. 7.1.2 To one 500 ml sample or to a sample diluted to 500 mL, add calcium hypochlorite solution dropwise while agitating and maintaining the pH between 11 and 12 with 1.25N sodium hydroxide until an excess of chlorine is present as indicated by Kl-starch paper turning blue. The sample will be subjected to alkaline chlorination by this step. CAUTION: The initial reaction product of alkaline chlorination is the very toxic gas cyanogen chloride; therefore, it is necessary that this reaction be performed in a hood. 7.1.3 Test for excess chlorine with Kl-starch paper and maintain this excess for one hour with continuous agitation. A distinct blue color on the test paper indicates a sufficient chlorine level. If necessary, add additional calcium hypochlorite solution. 7.1.4 After one hour, add 1 mL portions of 0.1N sodium arsenite until Kl-starch paper shows no residual chlorine. Add 5 mL of excess sodium arsenite to ensure the presence of excess reducing agent. 7.1.5 Test for total cyanide as described below in both the chlorinated and the unchlorinated samples. The difference of total cyanide in the chlorinated and unchlorinated samples is the cyanide amenable to chlorination. 7.1.6 If samples are known or suspected to contain sulfide, add 50 mL of 0.062M bismuth nitrate solution through the air inlet tube. Mix for three minutes. Use lead acetate paper to check the sample for the presence of sulfide. A positive test is indicated by a black color on the paper. 7.2 Distillation procedure 7.2.1 Place 500 mL of sample, or sample diluted to 500 mL in the one liter boiling flask. Pipet 50 mL of 1.25N sodium hydroxide into the gas scrubber. If the apparatus in Figure 1 is used, add water until the spiral is covered. Connect the boiling flask, condenser, gas scrubber and vacuum trap. 7.2.2 Start a slow stream of air entering the boiling flask by adjusting the vacuum source. Adjust the vacuum so that approximately two bubbles of air per second enter the boiling flask through the air inlet tube. 7.2.3 If samples are known or suspected to contain nitrate or nitrite, or if bismuth nitrate was added to the sample, add 50 mL of 0.4N sulfamic acid solution through the air inlet tube. Mix for three minutes. 9012B-5 Revision 2 August 2002 ------- NOTE: Excessive use of sulfamic acid could create method bias. 7.2.4 Slowly add 50 mL of 18N sulfuric acid through the air inlet tube. Rinse the tube with water and allow the airflow to mix the flask contents for three minutes. Add 20 mL of 2.5M magnesium chloride through the air inlet and wash the inlet tube with a stream of water. 7.2.5 Heatthe solution to boiling. Reflux for one hour. Turn off heat and continue the airflow for at least 15 minutes. After cooling the boiling flask, and closing the vacuum source, disconnect the gas scrubber. 7.2.6 Transferee solution from the scrubber into a 250-mLvolumetricflask. Rinse the scrubber into the volumetric flask. Dilute to volume with water. 7.3 Automated colorimetric determination 7.3.1 Set up the manifold in a hood or a well-ventilated area as shown in Figure 3. 7.3.2 Allow colorimeter and recorder to warm up for 30 min. Run a baseline with all reagents, feeding reagent water through the sample line. 7.3.3 Place appropriate standards in the sampler in order of increasing concentration. Complete loading of the sampler tray with unknown samples. 7.3.4 When the baseline becomes steady, begin the analysis. 7.4 Standard curve for samples without sulfide 7.4.1 Prepare a series of standards by pipetting suitable volumes of working standard potassium cyanide solution into 250-mL volumetric flasks. To each flask, add 50 ml of 1.25N sodium hydroxide and dilute to 250 mL with water. Prepare using the following table. The sodium hydroxide concentration will be 0.25N. mL of Working Standard Solution Concentration = 10ugCN-) (ug CNVL) 0.0 Blank 1.0 40 2.0 80 5.0 200 10.0 400 15.0 600 20.0 800 7.4.2 After the standard solutions have been prepared according to the table above, pipet 50 mL of each standard solution into a 100-mL volumetric flask and proceed to Sees 7.3.2 and 7.3.3 to obtain absorbance values for the standard curve. The final concentrations for the standard curve will be one half of the amounts in the above table (final concentrations ranging from 20 to 400 ug/L). 9012B-6 Revision 2 August 2002 ------- 7.4.3 It is recommended that at least two standards (a high and a low) be distilled and compared to similar values on the curve to ensure that the distillation technique is reliable. If distilled standards do not agree within + 10% of the undistilled standards, the analyst should find the cause of the apparent error before proceeding. 7.4.4 Prepare a standard curve ranging from 20 to 400 ug/L by plotting absorbance of standard versus the cyanide concentration 7.5 Standard curve for samples with sulfide 7.5.1 It is imperative that all standards be distilled in the same manner as the samples using the method of standard additions (for example, bismuth nitrate must also be added to the standards). Standards distilled by this method will give a linear curve, at low concentrations, but as the concentration increases, the recovery decreases. It is recommended that at least five standards be distilled. 7.5.2 Prepare a series of standards similar in concentration to those mentioned in Sec. 7.4.1 and analyze as in Sec. 7.3. Prepare a standard curve by plotting absorbance of standard versus the cyanide concentration. 7.6 Calculation: Prepare a standard curve by plotting peak heights of standards against their concentration values. Compute concentrations of samples by comparing sample peak heights with the standard curve. 8.0 QUALITY CONTROL 8.1 Refer to Chapter One for specific quality control procedures. 8.2 Verify the calibration curve with an independent calibration check standard. If the standards are not within 15% of the expected value, a new recalibration curve is required. Verify the calibration curve with every sample batch by analyzing a mid-range standard. 8.3 Run one matrix spike sample for every 10 samples to check the efficiency of sample distillation. A matrix spike should be prepared by adding cyanide from the working standard or intermediate standard to 500 mL of sample to ensure a concentration of approximately 40 ug/L Both the matrix duplicate and matrix spike duplicate are brought through the entire sample preparation and analytical process. 8.4 The method of standard additions shall be used for the analysis of all samples that suffer from matrix interferences such as samples which contain sulfides. 9.0 METHOD PERFORMANCE 9.1 Precision and accuracy data are not available at this time. 10.0 REFERENCES 1.

Stop J) 9012B-13 Revision 2 August 2002 ------- METHOD 9060A TOTAL ORGANIC CARBON 1.0 SCOPE AND APPLICATION 1.1 Method 9060 is used to determine the concentration of organic carbon in ground water, surface and saline waters, and domestic and industrial wastes. Some restrictions are noted in Sections 2.0 and 3.0. 1.2 Method 9060 is most applicable to measurement of organic carbon above 1 mg/L. 2.0 SUMMARY OF METHOD 2.1 Organic carbon is measured using a carbonaceous analyzer. This instrument converts the organic carbon in a sample to carbon dioxide (CO2) by either catalytic combustion or wet chemical oxidation. The CO2 formed is then either measured directly by an infrared detector or converted to methane (CH4) and measured by a flame ionization detector. The amount of CO2 or CH 4 in a sample is directly proportional to the concentration of carbonaceous material in the sample. 2.2 Carbonaceous analyzers are capable of measuring all forms of carbon in a sample. However, because of various properties of carbon-containing compounds in liquid samples, the manner of preliminary sample treatment as well as the instrument settings will determine which forms of carbon are actually measured. The forms of carbon that can be measured by Method 9060 are: 1. Soluble, nonvolatile organic carbon: e.g., natural sugars. 2. Soluble, volatile organic carbon: e.g., mercaptans, alkanes, low molecular weight alcohols. 3. Insoluble, partially volatile carbon: e.g., low molecular weight oils. 4. Insoluble, particulate carbonaceous materials: e.g., cellulose fibers. 5. Soluble or insoluble carbonaceous materials adsorbed or entrapped on insoluble inorganic suspended matter: e.g., oily matter adsorbed on silt particles. 2.3 Carbonate and bicarbonate are inorganic forms of carbon and must be separated from the total organic carbon value. Depending on the instrument manufacturer's instructions, this separation can be accomplished by either a simple mathematical subtraction, or by removing the carbonate and bicarbonate by converting them to CO2 with degassing prior to analysis. 3.0 INTERFERENCES 3.1 Carbonate and bicarbonate carbon represent an interference under the terms of this test and must be removed or accounted for in the final calculation. 9060A - 1 Revision 1 August 2002 ------- 3.2 This procedure is applicable only to homogeneous samples which can be injected into the apparatus reproducibly by means of a microliter-type syringe or pipet. The openings of the syringe or pipet limit the maximum size of particle which may be included in the sample. 3.3 Removal of carbonate and bicarbonate by acidification and purging with nitrogen, or other inert gas, can result in the loss of volatile organic substances. 4.0 APPARATUS AND MATERIALS 4.1 Apparatus for blending or homogenizing samples: Generally, a Waring-type blender is satisfactory. 4.2 Apparatus for total and dissolved organic carbon: 4.2.1 Several companies manufacture analyzers for measuring carbonaceous material in liquid samples. The most appropriate system should be selected based on consideration of the types of samples to be analyzed, the expected concentration range, and the forms of carbon to be measured. 4.2.2 No specific analyzer is recommended as superior. If the technique of chemical oxidation is used, the laboratory must be certain that the instrument is capable of achieving good carbon recoveries in samples containing particulates. 5.0 REAGENTS 5.1 ASTM Type II water (ASTM D1193): Water should be monitored for impurities, and should be boiled and cooled to remove CO2. 5.2 Potassium hydrogen phthalate. stock solution. 1,000 mg/L carbon: Dissolve 0.2128 g of potassium hydrogen phthalate (primary standard grade) in Type II water and dilute to 100.0 ml. NOTE: Sodium oxalate and acetic acid are not recommended as stock solutions. 5.3 Potassium hydrogen phthalate. standard solutions: Prepare standard solutions from the stock solution by dilution with Type II water. 5.4 Carbonate-bicarbonate, stock solution. 1,000 mg/L carbon: Weigh 0.3500 g of sodium bicarbonate and 0.4418 g of sodium carbonate and transfer both to the same 100-mL volumetric flask. Dissolve with Type II water. 5.5 Carbonate-bicarbonate, standard solution: Prepare a series of standards similar to Step 5.3. NOTE: This standard is not required by some instruments. 5.6 Blank solution: Use the same Type II water as was used to prepare the standard solutions. 9060A - 2 Revision 1 August 2002 ------- 6.0 SAMPLE COLLECTION, PRESERVATION, AND HANDLING 6.1 Sampling and storage of samples in glass bottles is preferable. Sampling and storage in plastic bottles such as conventional polyethylene and cubitainers is permissible if it is established that the containers do not contribute contaminating organics to the samples. NOTE: A brief study performed in the EPA Laboratory indicated that Type II water stored in new, 1-qt cubitainers did not show any increase in organic carbon after 2 weeks' exposure. 6.2 Because of the possibility of oxidation or bacterial decomposition of some components of aqueous samples, the time between sample collection and the start of analysis should be minimized. Also, samples should be kept cool (4ฐC) and protected from sunlight and atmospheric oxygen. 6.3 In instances where analysis cannot be performed within 2 hr from time of sampling, the sample is acidified (pH < 2) with HCI or H2SO4. 7.0 PROCEDURE 7.1 Homogenize the sample in a blender. NOTE: To avoid erroneously high results, inorganic carbon must be accounted for. The preferred method is to measure total carbon and inorganic carbon and to obtain the organic carbon by subtraction. If this is not possible, follow Steps 7.2 and 7.3 prior to analysis; however, volatile organic carbon may be lost. 7.2 Lower the pH of the sample to 2. 7.3 Purge the sample with nitrogen for 10 min. 7.4 Follow instrument manufacturer's instructions for calibration, procedure, and calculations. 7.5 For calibration of the instrument, a series of standards should be used that encompasses the expected concentration range of the samples. 7.6 Quadruplicate analysis is required. Report both the average and the range. 8.0 QUALITY CONTROL 8.1 All quality control data should be maintained and available for easy reference or inspection. 8.2 Employ a minimum of one blank per sample batch to determine if contamination or any memory effects are occurring. 8.3 Verify calibration with an independently prepared check standard every 15 samples. 8.4 Run one spike duplicate sample for every 10 samples. A duplicate sample is a sample brought through the whole sample preparation and analytical process. 9060A - 3 Revision 1 August 2002 ------- 9.0 METHOD PERFORMANCE 9.1 Precision and accuracy data are available in Method 415.1 of Methods for Chemical Analysis of Water and Wastes. 10.0 REFERENCES 1.

Revision 1 9070A -1 August 2002 ------- CHAPTER SIX PROPERTIES This chapter addresses procedures for method-defined parameters, where the analytical result is wholly dependant on the process used to make the measurement. Changes to the specific methods may change the end result and incorrectly identify a waste as nonhazardous. Therefore, when the measurement of such method-defined parameters is required by regulation, those methods are not subject to the flexibility afforded in other SW-846 methods (such as described in the Disclaimer and Chapter Two of this manual). The following methods are found in Chapter Six: Method 1030: Method 1120: Method 1312: Method 1320: Method 1330A: Method 9041A: Method 9045D: Method 9050A: Method 9080: Method 9081: Method 9090A: Method 9095B: Method 9096: Appendix A: Method 9100: Method 9310: Method 9315: Ignitability of Solids Dermal Corrosion Synthetic Precipitation Leaching Procedure Multiple Extraction Procedure Extraction Procedure for Oily Wastes pH Paper Method Soil and Waste pH Specific Conductance Cation-Exchange Capacity of Soils (Ammonium Acetate) Cation-Exchange Capacity of Soils (Sodium Acetate) Compatibility Test for Wastes and Membrane Liners Paint Filter Liquids Test Liquid Release Test (LRT) Procedure Liquid Release Test Pre-Test Saturated Hydraulic Conductivity, Saturated Leachate Conductivity, and Intrinsic Permeability Gross Alpha and Gross Beta Alpha-Emitting Radium Isotopes SIX-1 Revision 4 August 2002 ------- METHOD 9045D SOIL AND WASTE pH 1.0 SCOPE AND APPLICATION 1.1 Method 9045 is an electrometric procedure for measuring pH in soils and waste samples. Wastes may be solids, sludges, or non-aqueous liquids. If water is present, it must constitute less than 20% of the total volume of the sample. 2.0 SUMMARY OF METHOD 2.1 The sample is mixed with reagent water, and the pH of the resulting aqueous solution is measured. 3.0 INTERFERENCES 3.1 Samples with very low or very high pH may give incorrect readings on the meter. For samples with a true pH of >10, the measured pH may be incorrectly low. This error can be minimized by using a low-sodium-error electrode. Strong acid solutions, with a true pH of <1, may give incorrectly high pH measurements. 3.2 Temperature fluctuations will cause measurement errors. 3.3 Errors will occur when the electrodes become coated. If an electrode becomes coated with an oily material that will not rinse free, the electrode can (1) be cleaned with an ultrasonic bath, or (2) be washed with detergent, rinsed several times with water, placed in 1:10 HCI so that the lower third of the electrode is submerged, and then thoroughly rinsed with water, or (3) be cleaned per the manufacturer's instructions. 4.0 APPARATUS AND MATERIALS 4.1 pH Meter with means for temperature compensation. 4.2 Glass electrode. 4.3 Reference electrode: A silver-silver chloride or other reference electrode of constant potential may be used. NOTE: Combination electrodes incorporating both measuring and referenced functions are convenient to use and are available with solid, gel-type filling materials that require minimal maintenance. 4.4 Beaker: 50-mL. 4.5 Thermometer and/or temperature sensor for automatic compensation. 4.6 Analytical balance: capable of weighing 0.1 g. 9045D -1 Revision 4 August 2002 ------- 5.0 REAGENTS 5.1 Reagent grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Chemical Society, where such specifications are available. Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination. 5.2 Reagent water. All references to water in this method refer to reagent water, as defined in Chapter One. 5.3 Primary standard buffer salts are available from the National Institute of Standards and Technology (NIST) and should be used in situations where extreme accuracy is necessary. Preparation of reference solutions from these salts requires some special precautions and handling, such as low-conductivity dilution water, drying ovens, and carbon-dioxide-free purge gas. These solutions should be replaced at least once each month. 5.4 Secondary standard buffers may be prepared from NIST salts or purchased as solutions from commercial vendors. These commercially available solutions, which have been validated by comparison with NIST standards, are recommended for routine use. 6.0 SAMPLE PRESERVATION AND HANDLING Samples should be analyzed as soon as possible. 7.0 PROCEDURE 7.1 Calibration: 7.1.1 Because of the wide variety of pH meters and accessories, detailed operating procedures cannot be incorporated into this method. Each analyst must be acquainted with the operation of each system and familiar with all instrument functions. Special attention to care of the electrodes is recommended. 7.1.2 Each instrument/electrode system must be calibrated at a minimum of two points that bracket the expected pH of the samples and are approximately three pH units or more apart. Repeat adjustments on successive portions of the two buffer solutions until readings are within 0.05 pH units of the buffer solution value. If an accurate pH reading based on the conventional pH scale [0 to 14 at 25ฐC] is required, the analyst should control sample temperature at 25ฑ1 ฐC when sample pH approaches the alkaline end of the scale (e.g., a pH of 11 or above). 7.2 Sample preparation and pH measurement of soils: 7.2.1 To 20 g of soil in a 50-mL beaker, add 20 mL of reagent water, cover, and continuously stir the suspension for 5 minutes. Additional dilutions are allowed if working with hygroscopic soils and salts or other problematic matrices. 7.2.2 Let the soil suspension stand for about 1 hour to allow most of the suspended clay to settle out from the suspension or filter or centrifuge off the aqueous phase for pH measurement. 9045D - 2 Revision 4 August 2002 ------- 7.2.3 Adjust the electrodes in the clamps of the electrode holder so that, upon lowering the electrodes into the beaker, the glass electrode will be immersed just deep enough into the clear supernatant solution to establish a good electrical contact through the ground-glass joint or the fiber-capillary hole. Insert the electrodes into the sample solution in this manner. For combination electrodes, immerse just below the suspension. 7.2.4 If the sample temperature differs by more than 2ฐC from the buffer solution, the measured pH values must be corrected. 7.2.5 Report the results as "soil pH measured in water at _ฐC" where "_ฐC" is the temperature at which the test was conducted. 7.3 Sample preparation and pH measurement of waste materials 7.3.1 To 20 g of waste sample in a 50-mL beaker, add 20 mL of reagent water, cover, and continuously stir the suspension for 5 minutes. Additional dilutions are allowed if working with hygroscopic wastes and salts or other problematic matrices. 7.3.2 Let the waste suspension stand for about 15 minutes to allow most of the suspended waste to settle out from the suspension or filter or centrifuge off aqueous phase for pH measurement. NOTE: If the waste is hygroscopic and absorbs all the reagent water, begin the experiment again using 20 g of waste and 40 mL of reagent water. NOTE: If the supernatant is multiphasic, decant the oily phase and measure the pH of the aqueous phase. The electrode may need to be cleaned (Step 3.3) if it becomes coated with an oily material. 7.3.3 Adjust the electrodes in the clamps of the electrode holder so that, upon lowering the electrodes into the beaker, the glass electrode will be immersed just deep enough into the clear supernatant to establish good electrical contact through the ground- glass joint or the fiber-capillary hole. Insert the electrode into the sample solution in this manner. For combination electrodes, immerse just below the suspension. 7.3.4 If the sample temperature differs by more than 2ฐC from the buffer solution, the measured pH values must be corrected. 7.3.5 Report the results as "waste pH measured in water at __ฐC" where "_ฐC" is the temperature at which the test was conducted. 8.0 QUALITY CONTROL 8.1 Refer to Chapter One for the appropriate QC protocols. 8.2 Electrodes must be thoroughly rinsed between samples. 9.0 METHOD PERFORMANCE 9.1 No data provided. 9045D - 3 Revision 4 August 2002 ------- 10.0 REFERENCES 1.

Repeat experiment with 20 g waste and 40 mL water. Decant oily phase; measure pH of aqueous phase. Aqueous Phase 9045D- 5 Revision 4 August 2002 ------- METHOD 9095B PAINT FILTER LIQUIDS TEST 1.0 SCOPE AND APPLICATION 1.1 This method is used to determine the presence of free liquids in a representative sample of waste. 1.2 The method is used to determine compliance with 40 CFR 264.314 and 265.314. 2.0 SUMMARY OF METHOD 2.1 A predetermined amount of material is placed in a paint filter. If any portion of the material passes through and drops from the filter within the 5-min test period, the material is deemed to contain free liquids. 3.0 INTERFERENCES 3.1 Filter media were observed to separate from the filter cone on exposure to alkaline materials. This development causes no problem if the sample is not disturbed. 3.2 Temperature can affect the test results if the test is performed below the freezing point of any liquid in the sample. Tests must be performed above the freezing point and can, but are not required to, exceed room temperature of 25 ฐC. 4.0 APPARATUS AND MATERIALS 4.1 Conical paint filter: Mesh number 60 +/- 5% (fine meshed size). Available at local paint stores such as Sherwin-Williams and Glidden. 4.2 Glass funnel: If the paint filter, with the waste, cannot sustain its weight on the ring stand, then a fluted glass funnel or glass funnel with a mouth large enough to allow at least 1 in. of the filter mesh to protrude should be used to support the filter. The funnel should be fluted or have a large open mouth in order to support the paint filter yet not interfere with the movement, to the graduated cylinder, of the liquid that passes through the filter mesh. 4.3 Ring stand and ring, or tripod. 4.4 Graduated cylinder or beaker: 100-mL. 5.0 REAGENTS 5.1 None. 9095B -1 Revision 2 August 2002 ------- 6.0 SAMPLE COLLECTION, PRESERVATION, AND HANDLING A100-mL or 100-g representative sample is required for the test. If it is not possible to obtain a sample of 100 mL or 100 g that is sufficiently representative of the waste, the analyst may use larger size samples in multiples of 100 mL or 100 g, i.e., 200, 300, 400 mL or g. However, when larger samples are used, analysts shall divide the sample into 100-mL or 100-g portions and test each portion separately. If any portion contains free liquids, the entire sample is considered to have free liquids. If the sample is measured volumetrically, then it should lack major air spaces or voids. 7.0 PROCEDURE 7.1 Assemble test apparatus as shown in Figure 1. 7.2 Place sample in the filter. A funnel may be used to provide support for the paint filter. If the sample is of such light bulk density that it overflow the filter, then the sides of the filter can be extended upward by taping filter paper to the inside of the filter and above the mesh. Settling the sample into the paint filter may be facilitated by lightly tapping the side of the filter as it is being filled. 7.3 In order to assure uniformity and standardization of the test, material such as sorbent pads or pillows which do not conform to the shape of the paint filter, should be cut into small pieces and poured into the filter. Sample size reduction may be accomplished by cutting the sorbent material with scissors, shears, knife, or other such device so as to preserve as much of the original integrity of the sorbent fabric as possible. Sorbents enclosed in a fabric should be mixed with the resultant fabric pieces. The particles to be tested should be reduced smaller than 1 cm (i.e., should be capable of passing through a 9.5 mm (0.375 inch) standard sieve). Grinding sorbent materials should be avoided as this may destroy the integrity of the sorbent and produce many "fine particles" which would normally not be present. 7.4 For brittle materials larger than 1 cm that do not conform to the filter, light crushing to reduce oversize particles is acceptable if it is not practical to cut the material. Materials such as clay, silica gel, and some polymers may fall into this category. 7.5 Allow sample to drain for 5 min into the graduated cylinder. 7.6 If any portion of the test material collects in the graduated cylinder in the 5-min period, then the material is deemed to contain free liquids for purposes of 40 CFR 264.314 and 265.314. 8.0 QUALITY CONTROL 8.1 Duplicate samples should be analyzed on a routine basis. 9.0 METHOD PERFORMANCE 9.1 No data provided. 9095B - 2 Revision 2 August 2002 ------- 10.0 REFERENCES 10.1 None provided. 9095B - 3 Revision 2 August 2002 ------- FIGURE 1.

Examples include the use of the toxicity characteristic leaching procedure (TCLP) to prepare a leachate, and the flash point, pH, paint filter liquids, and corrosivity tests. In these instances, changes to the specific methods may change the end result and incorrectly identify a waste as nonhazardous. Therefore, when the measurement of such method-defined parameters is required by regulation, those methods are not subject to the flexibility afforded in other SW-846 methods (such as described in the Disclaimer and Chapter Two of this manual). 7.1 IGNITABILITY 7.1.1 Introduction This section discusses the hazardous characteristic of ignitability. The regulatory background of this characteristic is summarized, and the regulatory definition of ignitability is presented. The two testing methods associated with this characteristic, Methods 1010 and 1020, can be found in Chapter Eight. The objective of the ignitability characteristic is to identify wastes that either present fire hazards under routine storage, disposal, and transportation or are capable of severely exacerbating a fire once started. 7.1.2 Regulatory Definition See 40 CFR 261.21 for the regulatory definition of the hazardous waste characteristic of ignitability. 7.2 CORROSIVITY 7.2.1 Introduction The corrosivity characteristic, as defined in 40 CFR 261.22, is designed to identify wastes that might pose a hazard to human health or the environment due to their ability to: 1. Mobilize toxic metals if discharged into a landfill environment; 2. Corrode handling, storage, transportation, and management equipment; or 3. Destroy human or animal tissue in the event of inadvertent contact. In order to identify such potentially hazardous materials, EPA has selected two properties upon which to base the definition of a corrosive waste. These properties are pH and corrosivity toward Type SAE 1020 steel. SEVEN -1 Revision 4 August 2002 ------- The procedures for measuring pH of aqueous wastes are detailed in Method 9040, Chapter Six. Method 1110, Chapter Eight, describes how to determine whether a waste is corrosive to steel. Use Method 9095, Paint Filter Liquids Test, Chapter Six, to determine free liquid. 7.2.2 Regulatory Definition See 40 CFR 261.22 for the regulatory definition of the hazardous waste characteristic of corrosivity. 7.3 REACTIVITY 7.3.1 Introduction The regulation in 40 CFR 261.23 defines reactive wastes to include wastes that have any of the following properties: (1) readily undergo violent chemical change; (2) react violently or form potentially explosive mixtures with water; (3) generate toxic fumes when mixed with water or, in the case of cyanide- or sulfide-bearing wastes, when exposed to mild acidic or basic conditions; (4) explode when subjected to a strong initiating force; (5) explode at normal temperatures and pressures; or (6) fit within the Department of Transportation's forbidden explosives, Class A explosives, or Class B explosives classifications. This definition is intended to identify wastes that, because of their extreme instability and tendency to react violently or explode, pose a problem at all stages of the waste management process. The Agency relies entirely on a descriptive, prose definition of reactivity because available tests for measuring the variegated class of effects embraced by the reactivity definition suffer from a number of deficiencies. 7.3.2 Regulatory Definition See 40 CFR 261.24 for the regulatory definition of the hazardous waste characteristic of reactivity. 7.4 TOXICITY CHARACTERISTIC LEACHING PROCEDURE 7.4.1 Introduction The Toxicity Characteristic Leaching Procedure (TCLP) is designed to simulate the leaching a waste will undergo if disposed of in a sanitary landfill. This test is designed to simulate leaching that takes place in a sanitary landfill only. The extraction fluid employed is a function of the alkalinity of the solid phase of the waste. A subsample of a waste is extracted with the appropriate buffered acetic acid solution for 18 + 2 hours. The extract obtained from the TCLP (the "TCLP extract") is then analyzed to determine if any of the thresholds established for the 40 Toxicity Characteristic (TC) constituents (listed in Table 7-1) have been exceeded or if the treatment standards established for the constituents listed in 40 CFR 268.40 have been met under the Land Disposal Restrictions (LDR) regulations. If the TCLP extract contains any one of the TC constituents in an amount equal to or exceeding the concentrations specified in 40 CFR 261.24, the waste possesses the characteristic of toxicity and is a hazardous waste. If the TCLP extract contains constituents in an amount exceeding the concentrations specified in 40 CFR 268.40, the SEVEN - 2 Revision 4 August 2002 ------- treatment standard for that waste has not been met, and further treatment is necessary prior to land disposal. 7.4.2 Summary of Procedure The TCLP consists of five steps (refer to Figure 3): 1. Separation Procedure For liquid wastes (i.e.. those containing less than 0.5% dry solid material), the waste, after filtration through a 0.6 to 0.8 urn glass fiber filter, is defined as the TCLP extract. For wastes containing greater than or equal to 0.5% solids, the liquid, if any, is separated from the solid phase and stored for later analysis. 2. Particle Size Reduction Prior to extraction, the solid material must pass through a 9.5-mm (0.375-in.) standard sieve, have a surface area per gram of material equal to or greater than 3.1 cm2, or, be smaller than 1 cm in its narrowest dimension. If the surface area is smaller or the particle size larger than described above, the solid portion of the waste is prepared for extraction by crushing, cutting, or grinding the waste to the surface area or particle size described above. (Special precautions must be taken if the solids are prepared for organic volatiles extraction.) 3. Extraction of Solid Material The solid material from Step 2 is extracted for 18 + 2 hours with an amount of extraction fluid equal to 20 times the weight of the solid phase. The extraction fluid employed is a function of the alkalinity of the solid phase of the waste. A special extractor vessel is used when testing for volatile analytes. 4. Final Separation of the Extraction from the Remaining Solid Following extraction, the liquid extract is separated from the solid phase by filtration through a 0.6 to 0.8 urn glass fiber filter. If compatible, the initial liquid phase of the waste is added to the liquid extract, and these are analyzed together. If incompatible, the liquids are analyzed separately and the results are mathematically combined to yield a volume-weighted average concentration. 5. Testing (Analysis) of TCLP Extract Inorganic and organic species are identified and quantified using appropriate methods in the 6000, 7000, and 8000 series of methods in this manual or by other appropriate methods. 7.4.3 Regulatory Definition Under the Toxicity Characteristic, a solid waste exhibits the characteristic of toxicity if the TCLP extract from a subsample of the waste contains any of the contaminants listed in Table 7-1 at a concentration greater than or equal to the respective value given in that table. If a waste contains <0.5% filterable solids, the waste itself, after filtering, is considered to be the extract for the purposes of analysis. SEVEN - 3 Revision 4 August 2002 ------- Under the Land Disposal Restrictions regulations, a restricted waste identified in 40 CFR 268.40 cannot be land disposed if a TCLP extract of the waste or a TCLP extract of the treatment residue of the waste does exceeds the values shown in the table of 40 CFR 268.40 for any hazardous constituent listed in the table for that waste. If a waste contains <0.5% filterable solids, the waste itself, after filtering, is considered to be the extract for the purposes of analysis. SEVEN - 4 Revision 4 August 2002 ------- TABLE 7-1.

In these instances, changes to the specific methods may change the end result and incorrectly identify a waste as nonhazardous. Therefore, when the measurement of such method-defined parameters is required by regulation, those methods are not subject to the flexibility afforded in other SW-846 methods (such as described in the Disclaimer and Chapter Two of this manual). Methods for determining the characteristics of ignitability for liquids, corrosivity for liquids, and toxicity are included.

The following methods are found in Sec. 8.1 of this chapter: Method 1010A: Pensky-Martens Closed-Cup Method for Determining Ignitability Method 1020B : Small Scale Closed-Cup Method for Determining Ignitability EIGHT - 2 Revision 3 August 2002 ------- METHOD 101OA PENSKY-MARTENS CLOSED-CUP METHOD FOR DETERMINING IGNITABILITY 1.0 SCOPE AND APPLICATION 1.1 Method 1010 uses the Pensky-Martens closed-cup tester to determine the flash point of liquids including those that tend to form a surface film under test conditions. Liquids containing non-filterable, suspended solids can also be tested using this method. 1.2 This method is one of two method options required by 40 CFR 261.21(a)(1) in the determination of the hazardous waste ignitability characteristic. Method 1020 is the other method option. 2.0 SUMMARY OF METHOD 2.1 The sample is heated at a slow, constant rate with continual stirring. A small flame is directed into the cup at regular intervals with simultaneous interruption of stirring. The flash point is the lowest temperature at which application of the test flame ignites the vapor above the sample. 2.2 For complete instructions on how to conduct a test by this method, see Reference 4 below, "D 93-99c, Standard Test Methods for Flash-Point by Pensky-Martens Closed Cup Tester." 3.0 METHOD PERFORMANCE 3.1 The Pensky-Martens and Setaflash Closed Testers (Revision 0 of Method 1020) were evaluated using five industrial waste mixtures and p-xylene.

Method 1010 (Pensky-Martens Closed-Cup Method for Determining Ignitability) is the other method option. Liquids that tend to form surface films under test conditions or those that contain non-filterable suspended solids should be tested for the hazardous waste ignitability characteristic using Method 1010. 2.0 SUMMARY OF METHOD 2.1 By means of a syringe, 2-mL of sample is introduced through a leak-proof entry port into the tightly closed small scale tester or directly into the cup which has been brought to within 3 ฐC (5 ฐF) below the expected flash point. 2.2 As a flash/no-flash test, the expected flash-point temperature may be a specification (e.g., 60 ฐC). For specification testing, the temperature of the apparatus is raised to the precise temperature of the specification flash point by slight adjustment of the temperature dial. After 1 minute, a test flame is applied inside the cup and note is taken as to whether the test sample flashes or not. If a repeat test is necessary, a fresh sample should be used. 2.3 For a finite flash management, the temperature is sequentially increased through the anticipated range, the test flame being applied at 5 ฐC (9 ฐF) intervals until a flash is observed. A repeat determination is then made using a fresh sample, starting the test at the temperature of the last interval before the flash point of the material and making tests at increasing 0.5ฐC (1ฐF) intervals. 2.4 For the complete instructions on how to conduct the ignitability test by this method, see Reference 4 below, "D 3278-96, Standard Test Methods for Flash Point of Liquids by Small Scale Closed-Cup Apparatus." 3.0 METHOD PERFORMANCE See Method 1010. 4.0 REFERENCES 1.

Examples include the use of the toxicity characteristic leaching procedure (TCLP) to prepare a leachate, and the flash point, pH, paint filter liquids, and corrosivity tests. In these instances, changes to the specific methods may change the end result and incorrectly identify a waste as nonhazardous. Therefore, when the measurement of such method-defined parameters is required by regulation, those methods are not subject to the flexibility afforded in other SW-846 methods (such as described in the Disclaimer and Chapter Two of this manual). The following methods are found in Sec. 8.2 of this chapter: Method 9040C: pH Electrometric Measurement Method 111OA: Corrosivity Toward Steel EIGHT - 3 Revision 3 August 2002 ------- METHOD 9040C pH ELECTROMETRIC MEASUREMENT 1.0 SCOPE AND APPLICATION 1.1 Method 9040 is used to measure the pH of aqueous wastes and those multiphase wastes where the aqueous phase constitutes at least 20% of the total volume of the waste. 1.2 The corrosivity of concentrated acids and bases, or of concentrated acids and bases mixed with inert substances, cannot be measured. The pH measurement requires some water content. 2.0 SUMMARY 2.1 The pH of the sample is determined electrometrically using either a glass electrode in combination with a reference potential or a combination electrode. The measuring device is calibrated using a series of standard solutions of known pH. 3.0 INTERFERENCES 3.1 The glass electrode, in general, is not subject to solution interferences from color, turbidity, colloidal matter, oxidants, reductants, or moderate (<0.1 molar solution) salinity.. 3.2 Sodium error at pH levels >10 can be reduced or eliminated by using a low-sodium- error electrode. 3.3 Coatings of oily material or particulate matter can impair electrode response. These coatings can usually be removed by gentle wiping or detergent washing, followed by rinsing with distilled water. An additional treatment with hydrochloric acid (1:10) may be necessary to remove any remaining film. 3.4 Temperature effects on the electrometric determination of pH arise from two sources. The first is caused by the change in electrode output at various temperatures. This interference should be controlled with instruments having temperature compensation or by calibrating the electrode-instrument system at the temperature of the samples. The second source of temperature effects is the change of pH due to changes in the sample as the temperature changes. This error is sample-dependent and cannot be controlled. It should, therefore, be noted by reporting both the pH and temperature at the time of analysis. 4.0 APPARATUS AND MATERIALS 4.1 pH meter: Laboratory or field model. Many instruments are commercially available with various specifications and optional equipment. 4.2 Glass electrode. 4.3 Reference electrode: A silver-silver chloride or other reference electrode of constant potential may be used. 9040C -1 Revision 3 August 2002 ------- NOTE: Combination electrodes incorporating both measuring and referenced functions are convenient to use and are available with solid, gel-type filling materials that require minimal maintenance. 4.4 Magnetic stirrer and Teflon-coated stirring bar. 4.5 Thermometer and/or temperature sensor for automatic compensation. 5.0 REAGENTS 5.1 Reagent grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Chemical Society, where such specifications are available. Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination. 5.2 Primary standard buffer salts are available from the National Institute of Standards and Technology (NIST) and should be used in situations where extreme accuracy is necessary. Preparation of reference solutions from these salts requires some special precautions and handling, such as low-conductivity dilution water, drying ovens, and carbon-dioxide-free purge gas. These solutions should be replaced at least once each month. 5.3 Secondary standard buffers may be prepared from NIST salts or purchased as solutions from commercial vendors. These commercially available solutions have been validated by comparison with NIST standards and are recommended for routine use. 6.0 SAMPLE COLLECTION, PRESERVATION, AND HANDLING Samples should be analyzed as soon as possible. 7.0 PROCEDURE 7.1 Calibration 7.1.1 Because of the wide variety of pH meters and accessories, detailed operating procedures cannot be incorporated into this method. Each analyst must be acquainted with the operation of each system and familiar with all instrument functions. Special attention to care of the electrodes is recommended. 7.1.2 Each instrument/electrode system must be calibrated at a minimum of two points that bracket the expected pH of the samples and are approximately three pH units or more apart. (For corrosivity characteri-zation, the calibration of the pH meter should include a buffer of pH 2 for acidic wastes and a pH 12 buffer for caustic wastes; also, for corrosivity characterization, the sample must be measured at 25ฑ1 ฐC if the pH of the waste is above 12.0.) Various instrument designs may involve use of a dial (to "balance" or "standardize") or a slope adjustment, as outlined in the manufacturer's instructions. Repeat adjustments on successive portions of the two buffer solutions until readings are within 0.05 pH units of the buffer solution value. 9040C - 2 Revision 3 August 2002 ------- 7.2 Place the sample or buffer solution in a clean glass beaker using a sufficient volume to cover the sensing elements of the electrodes and to give adequate clearance for the magnetic stirring bar. If field measurements are being made, the electrodes may be immersed directly into the sample stream to an adequate depth and moved in a manner to ensure sufficient sample movement across the electrode-sensing element as indicated by drift-free readings (<0.1 pH). 7.3 If the sample temperature differs by more than 2ฐC from the buffer solution, the measured pH values must be corrected. Instruments are equipped with automatic or manual compensators that electronically adjust for temperature differences. Refer to manufacturer's instructions. 7.4 Thoroughly rinse and gently wipe the electrodes prior to measuring pH of samples. Immerse the electrodes into the sample beaker or sample stream and gently stir at a constant rate to provide homogeneity and suspension of solids. Note and record sample pH and temperature. Repeat measurement on successive aliquots of sample until values differ by <0.1 pH units. Two or three volume changes are usually sufficient. 8.0 QUALITY CONTROL 8.1 Refer to Chapter One for the appropriate QC protocols. 8.2 Electrodes must be thoroughly rinsed between samples. 9.0 METHOD PERFORMANCE 9.1 Forty-four analysts in twenty laboratories analyzed six synthetic water samples containing exact increments of hydrogen-hydroxyl ions, with the following results: Accuracy as Standard Deviation Bias Bias pH Units pH Units % pH Units 3.5 0.10 -0.29 -0.01 3.5 0.11 -0.00 7.1 0.20 +1.01 +0.07 7.2 0.18 -0.03 -0.002 8.0 0.13 -0.12 -0.01 8.0 0.12 +0.16 +0.01 10.0 REFERENCES 1.

However, large differences in corrosion rates may occasionally occur under conditions where the metal surfaces become passivated. Therefore, at least duplicate determinations of corrosion rate should be made. 4.0 APPARATUS AND MATERIALS 4.1 An apparatus should be used, consisting of a kettle or flask of suitable size (usually 500 to 5,000 mL), a reflux condenser, a thermowell and temperature regulating device, a heating device (mantle, hot plate, or bath), and a specimen support system. A typical resin flask set up for this type of test is shown in Figure 1. 4.2 The supporting device and container shall be constructed of materials that are not affected by, or cause contamination of, the waste under test. 4.3 The method of supporting the coupons will vary with the apparatus used for conducting the test, but it should be designed to insulate the coupons from each other physically and electrically and to insulate the coupons from any metallic container or other device used in the test. Some common support materials include glass, fluorocarbon, or coated metal. 4.4 The shape and form of the coupon support should ensure free contact with the waste. 4.5 A circular specimen of SAE 1020 steel of about 3.75 cm (1.5 in.) diameter is a convenient shape for a coupon. With a thickness of approximately 0.32 cm (0. 1 25 in.) and a 0.80- cm (0.4-in.)-diameter hole for mounting, these specimens will readily pass through a 45/50 ground- glass joint of a distillation kettle. The total surface area of a circular specimen is given by the following equation: A = - cf2) 1110A-1 Revision 1 August 2002 ------- where: t = thickness. D = diameter of the specimen. d = diameter of the mounting hole. If the hole is completely covered by the mounting support, the last term in the equation, (t)(3.14)(d), is omitted. 4.5.1 All coupons should be measured carefully to permit accurate calculation of the exposed areas. An area calculation accurate to ฑ1% is usually adequate. 4.5.2 More uniform results may be expected if a substantial layer of metal is removed from the coupons prior to testing the corrosivity of the waste. This can be accomplished by chemical treatment (pickling), by electrolytic removal, or by grinding with a coarse abrasive. At least 0.254 mm (0.0001 in.) or 2-3 mg/cm2 should be removed. Final surface treatment should include finishing with #120 abrasive paper or cloth. Final cleaning consists of scrubbing with bleach-free scouring powder, followed by rinsing in distilled water and then in acetone or methanol, and finally by air-drying. After final cleaning, the coupon should be stored in a desiccator until used. 4.5.3 The minimum ratio of volume of waste to area of the metal coupon to be used in this test is 40 mL/cm2. 5.0 REAGENTS 5.1 . Sodium hydroxide (NaOH). (20%): Dissolve200gNaOHin800mLTypellwaterand mix well. 5.2 Zinc dust. 5.3 Hydrochloric acid (HCI): Concentrated. 5.4 Stannous chloride (SnCI2). 5.5 Antimony chloride (SbCI3). 6.0 SAMPLE COLLECTION, PRESERVATION, AND HANDLING This method does not provide sample collection, preservation, and handling guidelines. 7.0 PROCEDURE 7.1 Assemble the test apparatus as described in Paragraph 4.0, above. 7.2 Fill the container with the appropriate amount of waste. 7.3 Begin agitation at a rate sufficient to ensure that the liquid is kept well mixed and homogeneous. 7.4 Using the heating device, bring the temperature of the waste to 55ฐC (130ฐF). 1110A 2 Revision 1 August 2002 ------- 7.5 An accurate rate of corrosion is not required; only a determination as to whether the rate of corrosion is less than or greater than 6.35 mm per year is required. A 24-hr test period should be ample to determine whether or not the rate of corrosion is >6.35 mm per year. 7.6 In order to determine accurately the amount of material lost to corrosion, the coupons have to be cleaned after immersion and prior to weighing. The cleaning procedure should remove all products of corrosion while removing a minimum of sound metal. Cleaning methods can be divided into three general categories: mechanical, chemical, and electrolytic. 7.6.1 Mechanical cleaning includes scrubbing, scraping, brushing, and ultrasonic procedures. Scrubbing with a bristle brush and mild abrasive is the most popular of these methods. The others are used in cases of heavy corrosion as a first step in removing heavily encrusted corrosion products prior to scrubbing. Care should be taken to avoid removing sound metal. 7.6.2 Chemical cleaning implies the removal of material from the surface of the coupon by dissolution in an appropriate solvent. Solvents such as acetone, dichloromethane, and alcohol are used to remove oil, grease, or resinous materials and are used prior to immersion to remove the products of corrosion. Solutions suitable for removing corrosion from the steel coupon are: Solution 20% NaOH + 200 g/L zinc dust Cone. HCI + 50 g/L SnCI2 + 20 g/L SbCI3 Soakinq Time 5 min Until clean Temperature Boiling Cold 7.6.3 Electrolytic cleaning should be preceded by scrubbing to remove loosely adhering corrosion products. One method of electrolytic cleaning that can be employed uses: Solution: 50 g/L H2SO4 Anode: Carbon or lead Cathode: Steel coupon Cathode current density: 20 amp/cm2 (129 amp/in.2) Inhibitor: 2 cc organic inhibitor/liter Temperature: 74ฐC (165ฐF) Exposure Period: 3 min. NOTE: Precautions must be taken to ensure good electrical contact with the coupon to avoid contamination of the cleaning solution with easily reducible metal ions and to ensure that inhibitor decomposition has not occurred. Instead of a proprietary inhibitor, 0.5 g/L of either diorthotolyl thiourea or quinolin ethiodide can be used. 7.7 Whatever treatment is employed to clean the coupons, its effect in removing sound metal should be determined by using a blank (i.e., a coupon that has not been exposed to the waste). The blank should be cleaned along with the test coupon and its waste loss subtracted from that calculated for the test coupons. 1110A-3 Revision 1 August 2002 ------- 7.8 After corroded specimens have been cleaned and dried, they are reweighed. The weight loss is employed as the principal measure of corrosion. Use of weight loss as a measure of corrosion requires making the assumption that all weight loss has been due to generalized corrosion and not localized pitting. In order to determine the corrosion rate for the purpose of this regulation, the following formula is used: Corrosion Rate (mmpy) = area x time where: weight loss is in milligrams, area is in square centimeters, time is in hours, and corrosion rate is in millimeters per year (mmpy). 8.0 QUALITY CONTROL 8.1 All quality control data should be filed and available for auditing. 8.2 Duplicate samples should be analyzed on a routine basis. 9.0 METHOD PERFORMANCE 9.1 No data provided. 10.0 REFERENCES 1.

EIGHT - 4 Revision 3 August 2002 ------- ------- 8.4 Toxicity This chapter addresses procedures for method-defined parameters, where the analytical result is wholly dependant on the process used to make the measurement. Examples include the use of the toxicity characteristic leaching procedure (TCLP) to prepare a leachate, and the flash point, pH, paint filter liquids, and corrosivity tests. In these instances, changes to the specific methods may change the end result and incorrectly identify a waste as nonhazardous. Therefore, when the measurement of such method-defined parameters is required by regulation, those methods are not subject to the flexibility afforded in other SW-846 methods (such as described in the Disclaimer and Chapter Two of this manual). The following methods are found in Sec. 8.4 of this chapter: Method 131 OB: Extraction Procedure (EP) Toxicity Test Method and Structural Integrity Test Method 1311: Toxicity Characteristic Leaching Procedure EIGHT - 5 Revision 3 August 2002 ------- METHOD 131 OB EXTRACTION PROCEDURE (EP) TOXICITY TEST METHOD AND STRUCTURAL INTEGRITY TEST 1.0 SCOPE AND APPLICATION 1.1 This method is used to determine whether a waste exhibits the characteristic of Extraction Procedure Toxicity. 1.2 The procedure may also be used to simulate the leaching which a waste may undergo if disposed of in a sanitary landfill. Method 1310 is applicable to liquid, solid, and multiphase samples. 2.0 SUMMARY OF METHOD 2.1 If a representative sample of the waste contains > 0.5% solids, the solid phase of the sample is ground to pass a 9.5 mm sieve and extracted with deionized water which is maintained at a pH of 5+ 0.2, with acetic acid. Wastes that contain < 0.5% filterable solids are, after filtering, considered to be the EP extract for this method. Monolithic wastes which can be formed into a cylinder 3.3 cm (dia) x 7.1 cm, or from which such a cylinder can be formed which is representative of the waste, may be evaluated using the Structural Integrity Procedure instead of being ground to pass a 9.5-mm sieve. 3.0 INTERFERENCES 3.1 Potential interferences that may be encountered during analysis are discussed in the individual analytical methods. 4.0 APPARATUS AND MATERIALS 4.1 Extractor - For purposes of this test, an acceptable extractor is one that will impart sufficient agitation to the mixture to (1) prevent stratification of the sample and extraction fluid and (2) ensure that all sample surfaces are continuously brought into contact with well-mixed extraction fluid. Examples of suitable extractors are shown in Figures 1-3 of this method and are available from: Associated Designs & Manufacturing Co., Alexandria, Virginia; Glas-Col Apparatus Co., Terre Haute, Indiana; Millipore, Bedford, Massachusetts; and Rexnard, Milwaukee, Wisconsin. 4.2 pH meter or pH controller - Accurate to 0.05 pH units with temperature compensation. 4.3 Filter holder - Capable of supporting a 0.45-um filter membrane and of withstanding the pressure needed to accomplish separation. Suitable filter holders range from simple vacuum units to relatively complex systems that can exert up to 5.3 kg/cm3 (75 psi) of pressure. The type of filter holder used depends upon the properties of the mixture to be filtered. Filter holders known to EPA and deemed suitable for use are listed in Table 1. 1310B-1 Revision 2 August 2002 ------- 4.4 Filter membrane - Filter membrane suitable for conducting the required filtration shall be fabricated from a material that (1) is not physically changed by the waste material to be filtered and (2) does not absorb or leach the chemical species for which a waste's EP extract will be analyzed. Table 2 lists filter media known to the Agency to be suitable for solid waste testing. 4.4.1 In cases of doubt about physical effects on the filter, contact the filter manufacturer to determine if the membrane or the prefilter is adversely affected by the particular waste. If no information is available, submerge the filter in the waste's liquid phase. A filter that undergoes visible physical change after 48 hours (i.e.. curls, dissolves, shrinks, or swells) is unsuitable for use. 4.4.2 To test for absorption or leaching by the filter: 4.4.2.1 Prepare a standard solution of the chemical species of interest. 4.4.2.2 Analyze the standard for its concentration of the chemical species. 4.4.2.3 Filter the standard and reanalyze. If the concentration of the filtrate differs from that of the original standard, then the filter membrane leaches or absorbs one or more of the chemical species and is not usable in this test method. 4.5 Structural integrity tester-A device meeting the specifications shown in Figure 4 and having a 3.18-cm (1.25-in) diameter hammer weighing 0.33 kg (0.73 Ib) with a free fall of 15.24 cm (6 in) shall be used. This device is available from Associated Design and Manufacturing Company, Alexandria, VA 22314, as Part No. 125, or it may be fabricated to meet these specifications. 5.0 REAGENTS 5.1 Reagent grade chemicals shall be used in all tests. Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Chemical Society, where such specifications are available. Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high purity to permit its use without lessening the accuracy of the determination. 5.2 Reagent water. All references to water in this method refer to reagent water, as defined in Chapter One. 5.3 Acetic acid (0.5N), CH3COOH. This can be made by diluting concentrated glacial acetic acid (17.5N) by adding 57 ml glacial acetic acid to 1,000 ml of water and diluting to 2 liters. The glacial acetic acid must be of high purity and monitored for impurities. 5.4 Analytical standards should be prepared according to the applicable analytical methods. 6.0 SAMPLE COLLECTION, PRESERVATION, AND HANDLING 6.1 Preservatives must not be added to samples. 131 OB-2 Revision 2 August 2002 ------- 6.2 Samples can be refrigerated if it is determined that refrigeration will not affect the integrity of the sample. 7.0 PROCEDURE 7.1 If the waste does not contain any free liquid, go to Step 7.9. If the sample is liquid or multiphase, continue as follows. Weigh filter membrane and prefilter to + 0.01 g. Handle membrane and prefilters with blunt curved-tip forceps or vacuum tweezers, or by applying suction with a pi pet. 7.2 Assemble filter holder, membranes, and prefilters following the manufacturer's instructions. Place the 0.45-um membrane on the support screen and add prefilters in ascending order of pore size. Do not prewet filter membrane. 7.3 Weigh out a representative subsample of the waste (100 g minimum). 7.4 Allow slurries to stand, to permit the solid phase to settle. Wastes that settle slowly may be centrifuged prior to filtration. 7.5 Wet the filter with a small portion of the liquid phase from the waste or from the extraction mixture. Transfer the remaining material to the filter holder and apply vacuum or gentle pressure (10-15 psi) until all liquid passes through the filter. Stop filtration when air or pressurizing gas moves through the membrane. If this point is not reached under vacuum or gentle pressure, slowly increase the pressure in 10-psi increments to 75 psi. Halt filtration when liquid flow stops. This liquid will constitute part or all of the extract (refer to Step 7.16). The liquid should be refrigerated until time of analysis. NOTE: Oil samples or samples containing oil are treated in exactly the same way as any other sample. The liquid portion of the sample is filtered and treated as part of the EP extract. If the liquid portion of the sample will not pass through the filter (usually the case with heavy oils or greases), it should be carried through the EP extraction as a solid. 7.6 Remove the solid phase and filter media and, while not allowing them to dry, weigh to + 0.01 g. The wet weight of the residue is determined by calculating the weight difference between the weight of the filters (Step 7.1) and the weight of the solid phase and the filter media. 7.7 The waste will be handled differently from this point on, depending on whether it contains more or less than 0.5% solids. If the sample appears to have < 0.5% solids, determine the percent solids exactly (see Note below) by the following procedure: 7.7.1 Dry the filter and residue at 80 ฐC until two successive weighings yield the same value. 7.7.2 Calculate the percent solids, using the following equation: weight of filtered solid and filters - tared weight of filters initial weight of waste material x100= % solids 1310B-3 Revision 2 August 2002 ------- NOTE: This procedure is used only to determine whether the solid must be extracted or whether it can be discarded unextracted. It is not used in calculating the amount of water or acid to use in the extraction step. Do not extract solid material that has been dried at 80ฐC. A new sample will have to be used for extraction if a percent solids determination is performed. 7.8 If the solid constitutes < 0.5% of the waste, discard the solid and proceed immediately to Step 7.17, treating the liquid phase as the extract. 7.9 The solid material obtained from Step 7.5 and all materials that do not contain free liquids shall be evaluated for particle size. If the solid material has a surface area per g of material > 3.1 cm2 or passes through a 9.5-mm (0.375-in.) standard sieve, the operator shall proceed to Step 7.11. If the surface area is smaller or the particle size larger than specified above, the solid material shall be prepared for extraction by crushing, cutting, or grinding the material so that it passes through a 9.5-mm (0.375-in.) sieve or, if the material is in a single piece, by subjecting the material to the "Structural Integrity Procedure" described in Step 7.10. 7.10 Structural Integrity Procedure (SIP) 7.10.1 Cut a 3.3-cm diameter by 7.1-cm long cylinder from the waste material. If the waste has been treated using a fixation process, the waste may be cast in the form of a cylinder and allowed to cure for 30 days prior to testing. 7.10.2 Place waste into sample holder and assemble the tester. Raise the hammer to its maximum height and drop. Repeat 14 additional times. 7.10.3 Remove solid material from tester and scrape off any particles adhering to sample holder. Weigh the waste to the nearest 0.01 g and transfer it to the extractor. 7.11 If the sample contains > 0.5% solids, use the wet weight of the solid phase (obtained in Step 7.6) to calculate the amount of liquid and acid to employ for extraction by using the following equation: W = W, - W, where: W = Wet weight in g of solid to be charged to extractor. W, = Wet weight in g of filtered solids and filter media. W, = Weight in g of tared filters. If the waste does not contain any free liquids, 100 g of the material will be subjected to the extraction procedure. 7.12 Place the appropriate amount of material (refer to Step 7.11) into the extractor and add 16 times its weight with water. 131 OB-4 Revision 2 August 2002 ------- 7.13 After the solid material and water are placed in the extractor, the operator shall begin agitation and measure the pH of the solution in the extractor. If the pH is > 5.0, the pH of the solution should be decreased to 5.0+ 0.2 by slowly adding 0.5N acetic acid. If the pH is < 5.0, no acetic acid should be added. The pH of the solution should be monitored, as described below, during the course of the extraction, and, if the pH rises above 5.2,0.5N acetic acid should be added to bring the pH down to 5.0 ฑ 0.2. However, in no event shall the aggregate amount of acid added to the solution exceed 4 mL of acid per g of solid. The mixture should be agitated for 24 hours and maintained at20-40ฐC (68-104ฐF) during this time. It is recommended that the operator monitor and adjust the pH during the course of the extraction with a device such as the Type 45-A pH Controller, manufactured by Chemtrix, Inc., Hillsboro, Oregon 97123, or its equivalent, in conjunction with a metering pump and reservoir of 0.5N acetic acid. If such a system is not available, the following manual procedure shall be employed. NOTE: Do not add acetic acid too quickly. Lowering the pH to below the target concentration of 5.0 could affect the metal concentrations in the leachate. 7.13.1 A pH meter should be calibrated in accordance with the manufacturer's specifications. 7.13.2 The pH of the solution should be checked, and, if necessary, 0.5 N acetic acid should be manually added to the extractor until the pH reaches 5.0 + 0.2. The pH of the solution should be adjusted at 15-, 30-, and 60-minute intervals, moving to the next longer interval if the pH does not have to be adjusted > 0.5 pH units. 7.13.3 The adjustment procedure should be continued for at least 6 hours. . 7.13.4 If, at the end of the 24-hour extraction period, the pH of the solution is not below 5.2 and the maximum amount of acid (4 ml per g of solids) has not been added, the pH should be adjusted to 5.0 + 0.2 and the extraction continued for an additional 4 hours, during which the pH should be adjusted at 1-hour intervals. 7.14 At the end of the extraction period, water should be added to the extractor in an amount determined by the following equation: V = (20)(W)-16(W)-A where: V = ml water to be added. W = Weight in g of solid charged to extractor. A = ml of 0.5N acetic acid added during extraction. 7.15 The material in the extractor should be separated into its component liquid and solid phases in the following manner: 7.15.1 Allow slurries to stand to permit the solid phase to settle (wastes that are slow to settle may be centrifuged prior to filtration) and set up the filter apparatus (refer to Steps 4.3 and 4.4). 131 OB-5 Revision 2 August 2002 ------- 7.15.2 Wet the filter with a small portion of the liquid phase from the waste or from the extraction mixture. Transfer the remaining material to the filter holder and apply vacuum or gentle pressure (10-15 psi) until all liquid passes through the filter. Stop filtration when air or pressurizing gas moves through the membrane. If this point is not reached under vacuum or gentle pressure, slowly increase the pressure in 10-psi increments to 75 psi. Halt filtration when liquid flow stops. 7.16 The liquids resulting from Steps 7.5 and 7.15 should be combined. This combined liquid (or waste itself, if it has < 0.5% solids, as noted in Step 7.8) is the extract. 7.17 The extract is then prepared and analyzed using the appropriate analytical methods described in Chapters Three and Four of this manual. NOTE: If the EP extract includes two phases, concentration of contaminants is determined by using a simple weighted average. For example: An EP extract contains 50 ml of oil and 1,000 ml of an aqueous phase. Contaminant concentrations are determined for each phase. The final contamination concentration is taken to be: (50x contaminant cone, in oil) + (1,000* contaminant cone, of aqueous phase) 1050 NOTE: In cases where a contaminant was not detected, use the MDL in the calculation. For example, if the MDL in the oily phase is 100 mg/L and 1 mg/L in the aqueous phase, the reporting limit would be 6 mg/L (rounded to the nearest mg). If the regulatory threshold is 5 mg/L, the waste may be EP toxic and results of the analysis are inconclusive. 8.0 QUALITY CONTROL 8.1 All quality control data should be maintained and available for easy reference or inspection. 8.2 Employ a minimum of one blank per sample batch to determine if contamination or any memory effects are occurring. 8.3 All quality control measures described in Chapter One and in the referenced analytical methods should be followed. 9.0 METHOD PERFORMANCE 9.1 The data tabulated in Table 3 were obtained from records of state and contractor laboratories and are intended to show the precision of the entire method (1310 plus analysis method). 131 OB-6 Revision 2 August 2002 ------- 10.0 REFERENCES 1.
