This publication reports the results of EPA's interlaboratory study for the following priority pollutants: Aldrin Dieldrin Toxaphene a-BHC Endosulfan I Aroclor 1016 B-BHC Endosulfan II Aroclor 1221 y-BHC Endosulfan sulfate Aroclor 1232 6-BHC Endrin Aroclor 1242 4,4'-DDD Heptachlor Aroclor 1248 4»41-DDE Heptachlor epoxide Aroclor 1254 4,4'-DDT Chiordane Arocl or 1260 Federal agencies, states, municipalities, universities, private 1aboratories, and industry should find this evaluative study of assistance in monitoring and controlling pollution in the environment. R. L. Booth Director, EMSL-Cincinnati 111 ------- ABSTRACT This report describes the results obtained and data analyses from an Inter!aboratory study of EPA Method 608 (Organochlorine Pesticides and PCBs). The method is designed to analyze for 16 single-compound pesticides, chlordane, toxaphene, and seven Aroclor formulations in water and wastewater. All were included in this study except endrin aldehyde, sufficient quantities of which could not be obtained. As tested here, the method utilizes three 60-mL extractions with dichloromethane, cleanup/ separation on a Florisil column, and injection into a gas chromatograph equipped with an electron capture detector. The study design required the analyst to dose six waters with eight analytical groups, each at six levels. The six dosing levels of each substance or combination represented three Youden pairs, one each at a low, an intermediate, and a high level. The six waters used were a laboratory pure water, a finished drinking water, and a surface water, collected by the participant, and three low-background industrial effluents (SICs 2869, 2869, and 2621) provided by the prime contractor. A total of 22 laboratories participated in the study. The method is assessed quantitatively with respect to the accuracy and precision that can be expected. In addition, results of method detection limit studies are included as are qualitative assessments of the method based upon comments by the participating laboratories. The work was performed between September 1978 to December 1981 under Contract 68-03-2606. i v ------- CONTENTS Page Foreword iii Abstract iv Tables vi Acknowledgment ix 1. Introduction • 1 2.

Ivy, Southwest Research Institute, for his valuable help in obtaining the industrial effluents that were used in this work. ix ------- SECTION 1 INTRODUCTION EPA first promulgated guidelines [1] establishing test procedures for the analysis of pollutants in 1973, following the passage of the Federal Water Pollution Control Act in 1972 by Congress. Pursuant to the amendment and publication of these guidelines, EPA entered into a Settlement Agreement—the Consent Decree—which required the study and, if necessary, regulation of 65 "priority" pollutants and classes of pollutants of known or suspected toxicity to the biota. Subsequently, Congress passed the Clean Water Act of 1977 [2], mandating the control of toxic pollutants discharged into ambient waters by industry. In order to facilitate the implementation of the Clean Water Act, EPA selected 129 specific toxic pollutants, 113 organic and 16 inorganic, for initial study. The organic pollutants were divided into 12 categories based on their chemical structure. Analytical methods were developed by EPA for these 12 categories through in-house and contracted research. These analytical methods may eventually be required for the monitoring of the 113 toxic pollutants in Industrial wastewater effluents, as specified by the Clean Water Act of 1977. As a logical subsequence to the work that produced proposed EPA Method 608 (Organochlorine Pesticides and PCBs) [3], an inter!aboratory study was conducted to determine the precision and accuracy of the proposed method. This report describes the work performed, presents the data acquired, and gives the conclusions drawn from the collaborative effort. Of the 25 priority pollutants named in Method 608, 24 were tested in this study. Endrin aldehyde, which is included in Method 608, was eliminated from this study because it could not be obtained in sufficient quantity for the study, except through a costly synthesis effort. The 24 substances were handled in eight groups during the analytical determinations in order to minimize the number of individual operations that had to be performed. Even so, a very substantial effort had to be made by each participating laboratory in order to perform the required 1 ------- analyses. The shortest period of performance recorded by any laboratory, measured from the time samples were received and the complete data package was submitted, was 3-1/2 months. The eight groups of substances were as follows: GROUP I GROUP II o-BHC •0-BHC 6-BHC Heptachlor epoxide DDE DDD DDT Endosulfan sulfate y-BHC Heptachlor Aldrin Endosulfan I Dieldrin Endrin Endosulfan II GROUP III GROUP IV GROUP V GROUP VI GROUP VII GROUP VIII Chlordane Toxaphene Aroclor 1242 + Aroclor 1254 Aroclor 1232 + Aroclor 1260 Aroclor 1221 + Aroclor 1248 Aroclor 1016 The non-EPA laboratories participating in this study were the 20 lowest bidders from the list of qualifying laboratories that responded to the request for bids. Qualifications were established based upon information submitted by the laboratories. The laboratories were selected to be typical of the laboratories that would utilize the method when it went into widespread usage. The participating laboratories are listed in Figure 1. The laboratories are identified by number in this report and no correlation between the identifying number and the order of laboratories in the list of participating laboratories should be presumed. The EPA laboratories participating were on a voluntary basis. 2 ------- Becton Dickinson and Company P. 0.

Participating Laboratories 3 ------- SECTION 2 SUMMARY As a result of the collaborative study conducted and the data analysis, the following conclusions can be drawn concerning EPA Method 608 (Organochlorine Pesticides and PCBs). The accuracy of the method could generally be expressed as a linear function of the true concentration. The regression equations are shown in Table 1. • The precision of the method could generally be expressed as a linear function of the mean recovery. These regression equations are also shown in Table 1. • Recoveries at the midrange concentration were similar to those obtained during the developmental phase in many instances and lower in others, indicating satisfactory method performance. The recoveries ranged from 68 to 101% of for single-compound pesticides, 73 to 86% for multiple-compound pesticides, and 69 to 101% for the PCB formulations in the first five matrices. Lower recoveries were obtained in the third industrial effluent due to emulsion formation. Eighty-six percent of the recoveries among the first five matrices exceeded 80% and 12.5% exceeded 90%. • At the midrange concentration, overall percent relative standard deviations of 12 to 45, 19 to 36 and 14 to 40% were obtained for the above three groupings of compounds among the first five matrices. The single-analyst percent relative standard deviations were from 11 to 33, 10 to 31 and 12 to 28%, respectively, under the same conditions. Poorer precision was obtained for industrial effluent 3, as expected, due to its nature. • Six water types were used in this study: laboratory pure, finished drinking, surface, and three industrial effluents. The only significant difference among the results obtained was in the recovery of the substances from the third industrial effluent. 4 ------- TABLE 1.

According to Youden's design, samples are analyzed in pairs, and each sample of a pair has a slightly different concentration of the constituent. The analyst is directed to do a single analysis and report one value for each sample, as if for a normal, routine sample. In this study, samples were prepared as concentrates in sealed glass ampules and shipped to the analyst along with portions of final effluents from manufacturing plants from three relevant Industries. Each participating laboratory was responsible for supplying laboratory pure water, finished water, and a surface water, thus giving a total of six water matrices involved in the study. The analyst was required to add an aliquot of each concentrate to a volume of water from each of the six waters and submit the spiked water to analysis. Three pairs of samples were used. One pair contained the substances at what was considered to be equivalent to a low level for the industrial effluents; a second pair contained the substances at an intermediate level and the third pair contained the substances at a high level. TEST DESIGN A summary of the test design using Youden's nonreplicate technique for x and y samples is given below: 1. Three Youden pairs were used for each parameter with the deviation from the mean of each pair being at least 5% but no more than 20. 2. The three Youden pairs were spread over a usable and realistic range with the lowest level estimated to be near the detection limit in industrial effluent with the highest background of electron capture-sensitive substances. 3. Analyses were performed in six waters. Three of the waters were selected from relevant industries as determined by the 10 ------- information contained in a memorandum of December 29, 1978 from M. Dean Neptune, Analytical Programs, Effluent Guidelines Division, to R. B. Schaffer, Director, Effluent Guidelines Division, through W. A. TelHard, Chief, Energy and Mining Branch. Therefore, each participant was to generate 36 data points for each substance. 4. Two hundred eighty-eight samples (eight analytical groups x six concentrations x six replicates) prepared as stable concentrates in sealed glass ampules were shipped with approximately 61 liters each of the three industrial effluents to 20 non-EPA laboratories and to two EPA laboratories. The concentrations of substances in the ampules were unknown to the participants. 5. Each participant was supplied with a copy of Method 608 and supplementary instructions relative to spiking procedure, cleanup column to be used, GC column and detector to be used, and GC injection technique. 6. To commence an analysis, the analyst was instructed to open an ampule, add 1 mL of concentrate to 1 L of water, and analyze per instructions. . 7. Each sample was to be analyzed once. 8. Before the formal study began, each participant was sent a pair of ampules (not one of the pairs used in the study) for a trial analysis by Method 608. After submitting data from these analyses to SwRI, participants met in Cincinnati to discuss and resolve problems encountered during the trial run. 9. Fifty ampules of each concentrate prepared were supplied to the project officer. PREPARATION OF SAMPLES, WASTEWATER SELECTION, AND PROCUREMENT The pesticide and PCB substances used to prepare sample concentrates were obtained from several commercial sources and from the Quality Assurance Section, EPA, HERL, ETD, ACB (MD-69), Research Triangle Park, North Carolina. Substances obtained from commercial sources were compared to those from the EPA to establish that purity and GC profile, 1n the case of multipeak substances, and were found to be satisfactory. The detailed protocol for concentrate and ampule production was reviewed and approved by the project officer before ampule production 11 ------- commenced. Salient points of the protocol are described in the following paragraph. Sample concentrates were prepared by dissolving precisely-weighed (analytical balance) amounts in methyl alcohol or acetone in Class A volunetric flasks. Where dilutions were required, Class A volumetric glass pipettes were used to transfer the required volumes. The volumes transferred were never less than 4 mL. Solutions were put into brown, borosilicate ampules, chilled, and heat-sealed. All glassware had been fired overnight at approximately 400°C before use. The sealed ampules were stored in paperboard boxes at room temperature until shipped to participants. Before each concentrate was used to fill ampules, the concentration(s) of substance(s) was compared with a standard that had been prepared from a separate weighing of substance(s). Three ampules taken at random from the ampules produced were checked against the same external standard mentioned immediately above. These verification checks served to prevent gross errors from being committed; the true values were assumed to be those established by the weighing of substance for concentrate preparation. It was rare to find-a verification analysis which deviated more than 5% from the true value. The true values for all test substances are given in Table 2. One of the three wastewaters selected for use in the study was from a pesticide plant (SIC 2869-industrial effluent 1), one from an organics and plastics plant (SIC 2869-industrial effluent 2), and the third from a kraft paper mill (SIC 2621-industrial effluent 3). Industrial effluent 1 had a relatively high interference background; however, only two of the peaks coeluted with standards--heptachl or and endosulfan II. The amounts indicated were in the low parts per trillion range. Peaks eluting in the first four minutes offered a good challenge to the detection of the lowest Youden pair peaks in this area. Industrial effluent 2 offered low to moderate interferences from substances that were not parameters under test. Upon standing several months this water developed peaks that were strongly suspected to be from elemental sulfur, causing mercury treatment of extracts to be necessary in many instances. Industrial effluent 3 formed a tenacious emulsion that required centrifugation to break. Even then, only about 60% of the extracting solvent was usually recovered. Severe Interferences from elemental sulfur peaks were present in the extracts but these could be eliminated almost totally with mercury treatment. 12 ------- TABLE 2.

Industrial effluent 1 was not pooled before shipment but samples taken from barrels 1, 5, and 10 gave chromatograms that were indistinguishable from one another; therefore, homogeneity was assumed- Industrial effluents 2 and 3 were pooled in a 600-gallon tank before being put in bottles. ANALYSIS AND REPORTING In addition to admonitions to follow Method 608 procedure, supplementary instructions were sent to participants at the time the trial run ampules were shipped. Participants were advised how to dose the water, to use only a Florisil cleanup column, and to make injections of extract Into the GC using the solvent-flush technique described by Burke [5], if manual injections were used. Only electron capture detectors were to be used. Acceptable dose-response data for dieldrin were included as an aid to determining the performance of an electron capture detector. Also, the request was made that all pertinent GC recorder charts be sent with the data submitted for the trial run and the formal tests to follow. At the Cincinnati conference, trial run data were presented and a step-by-step discussion of the method was given. The most common errors (calculation, standards preparation, and improper expression of results) were pointed out. At the meeting, the following supplementary instructions were given: 1. Column 1, as given in Method 608, and electron capture detectors will be used by all participants. 2. Quantitation of the multipeak substances will be left to the discretion of the analyst with respect to the number of peaks used and whether or not to average the values if more peaks than one are followed in the analyses. 3. The three fractions (6?, 15%, and 50% ethyl ether fractions) will be separated on Florisil in the analyses of Groups I and II during the analyses of all unspiked and spiked waters. After the Cincinnati conference, a follow-up letter was sent to each participant requesting that the example data calculation sheets and data summary sheets that were enclosed be used during the study. The same letter requested that the final report include information on the following: 14 ------- 1. method of quantitating multipeak substances; 2. sources of standards; 3. source of surface water and the nature of any possible contaminants; 4. suggestions as to how Method 608 could be improved. DISTRIBUTION OF SAMPLES A single shipment of 288 ampules was made by overnight air express to all laboratories. No instance of ampule breakage during shipment was reported. However, some participants reported shortages or having received empty, unbroken ampules and others accidentally broke ampules during the study. Replacement ampules were provided in these cases. The water matrices were also shipped by overnight air express, each participant receiving 61 liters (16 gallons) of each of the three industrial effluents. The time required to collect and distribute the effluents was about six weeks. Only 2 gallons were reported to have been broken in transit. Several gallons were broken or otherwise made unusable through laboratory mishaps. Replacement shipments were made in these instances. Specifications within the scope of work required that concentrates for spiking exhibit satisfactory stability for 45 days before the trial run ampules could be sent out and for 90 days before shipments for the formal study could commence. These milestones were passed without significant difficulty. The stability measurements consisted of comparing the highest level of the middle Youden pair against freshly prepared standards. Four ampules were withdrawn at random at 0-, 45-, and 90-day periods. Triplicate GC injections of the properly diluted content were made and the average value obtained compared to the freshly prepared standards. Deviations from the true value varied in a manner similar to that observed during the verification analyses. Thus, stability was considered to be satisfactory. The solvent for all concentrations, except Group II, was methyl alcohol. The solvent for Group II was acetone. These solvents were chosen because of their hydrophilicity and satisfactory performance during informal stability tests conducted earlier in the program. During these tests the only unstable combinations noted were acetone-endosulfan sulfate and methyl al cohol-endosul fan II. Thus, acetone was chosen for Group II concentrates and methyl alcohol for the others. 15 ------- The unrefrigerated plant effluents remaining in reserve at SwRI were periodically examined by extraction and GC injection. Industrial effluents 1 and 3 were not observed to change but industrial effluent 2 exhibited what appeared to be typical sulfur peaks after standing for 2 months. These peaks were reducible by applying the mercury cleanup treatment as given in Method 608. Participants were advised by letter to be on the lookout for such changes in the extract profile for industrial effluent 2 and to apply the mercury cleanup where the need was indicated. 16 ------- SECTION 4 TREATMENT OF DATA The objective of this interlaboratory study was to obtain information about the accuracy and precision associated with measurements generated by Method 608. This objective was met through the use of statistical analysis techniques designed to extract and summarize the relevant information about accuracy and precision from the data reported by the participating laboratories. The statistical techniques employed in the data reduction process are similar to the techniques suggested in the ASTM Standard Practice D2777-77. The algorithms required to perform the statistical analyses have been integrated into a system of computer programs referred to as IMVS (Interlaboratory Method Validation Study), The analyses performed by IMVS [6] include several tests for the rejection of outliers (laboratories and individual data points), summary statistics by concentration level for mean recovery (accuracy), overall and single-analyst standard deviation (precision), determination of the linear relationship between mean recovery and concentration level, determination of the linear relationship between the precision statistics and mean recovery, and a test for the effect of water type on accuracy and precision. A detailed description of each of the statistical analysis procedures is presented below. PREPROCESSING An initial review of the data was performed to determine if a systematic error was evident in the data that could be identified and legitimately corrected prior to data analysis. Chromatograms and supporting data were investigated to verify that the analyses were run under the proper conditions and that calculations were accurate and supportable. Where an anomaly existed, such as a series of results that were different from the true values by one or more orders of magnitude, the analyst was contacted, told that there was an apparent error, and asked to check his values. No indication was given as to the nature of the 17 ------- inconsistency in order not to prejudice the results. If an error was found, the corrected values were used in the data analyses. If the analyst reported no error could be found, the data were allowed to stand as reported. All analyses reported as less than a detection limit and results that the analysts noted as influenced by spillage or loss of sample were removed from the data set prior to insertion into the computer program. The data set thus prepared was utilized in the statistical analysis supplied by the sponsor. REJECTION OF OUTLIERS Spurious data points are always a part of any set of data collected during an interlaboratory test program. It is important to identify and remove these data points because they can lead to values of summary statistics which are not representative of the general behavior of the method. However, some erratic behavior in the data may be directly related to some facet of the method under the study. Therefore, spurious data points should not be removed indiscriminantly, and any points that are removed should be clearly identified since further investigation of the analytical conditions related to the outliers might be of value. Data rejected as outliers for this study as a result of any of the following tests for outliers have been identified by the symbol in the raw data tables. YOUDEN'S LABORATORY RANKING PROCEDURE In some cases the analytical values reported by a specific laboratory are so consistently high or low that a large systematic error may be attributed to that laboratory. These data are not representative of the method and should be rejected. Youden's [4] ranking test for outlying laboratories was applied separately to data from each of the waters used in this study. Since six water types were used in this study, the laboratory ranking procedure was applied to these six different subsets of the data. Each laboratory ranking test was performed at the 5% level of significance. The Youden laboratory ranking procedure requires a complete set of data from every laboratory within a given water type. Missing data from labortory i for water type j were replaced by the following procedure. Letting X-jj^ denote the reported measurement from laboratory i for water type j and concentration level it is assumed that xijk = 3j'CkYj-Li-cijk 18 ------- where Bj and Yj are fixed parameters which determine the effect of water type j, L-j is the systematic error due to laboratory i and c-fj^ is the random within laboratory error. Taking natural logarithms, it follows that in X i j ¦ Jin ^ Yj ^ ^ in ^ in £ j j\|^ which is a linear regression model with dependent variable in X^ and independent variable in C^. (Details and justification for this model are discussed in the section "Comparison of Accuracy and Precision Across Water Types.") The natural logarithms of the individual laboratory's data were regressed against the natural logarithms of the true concentration levels for the six ampules in each water type. The predicted values in Xij^ were obtained from the regression equation, and the missing values for X-jj^ were estimated byT-jjk = exp(in Xi j^, where exp (c) denotes the constant e raised to the c power. If the ranking test rejected a laboratory for a specific water type, then all of the laboratory data for that water type were rejected as outliers. The rejected values were excluded from all the remaining analyses. In addition, after completion of the laboratory ranking procedure, the predicted values created to fill in for the missing data were rejected and excluded from further analyses for all laboratories. TESTS FOR INDIVIDUAL OUTLIERS The data remaining after the laboratory ranking procedure were grouped by water type. For each water type, the data were broken down into six subsets defined by the six concentration levels (ampules) used in the study. For each subset of the data, all missing, zero, "less than" and "nondetect" data were rejected. Next, the test for individual outliers constructed by Thompson [7] and suggested in the ASTM Standard Practice D2777-77 was applied to the data using a 5% significance level. If an individual data point was rejected based on this test, it was removed from the subset, and the test was repeated using the remaining data in the subset. This process was continued until no additional data could be rejected. STATISTICAL SlfftlARlES Several summary statistics were calculated using the data remaining for each concentration level after the outlier rejection tests were 19 ------- performed. These summary statistics include: the number of retained data points, the mean recovery, accuracy as a percent relative error, the absolute overall standard deviation, the percent relative overall standard deviation, the absolute single-analyst standard deviation, and the percent relative single-analyst standard deviation. The basic formulas used to calculate these statistics are presented below where Xj, X£, Xn denote the values of the n retained data points for a specific concentration level. Mean Recovery (X): n z i=l X = ± l Xi The conventional notation for mean recovery is X; however the symbol X is used in this report to be consistent with the output from the computer program. Accuracy as a % Relative Error: X - True Value WE - True Value x 100 Overall Standard Deviation: S = = $ m (Xi'x)2 and Percent Relative Overall Standard Deviation: RSD = (\|) x 100 The overall standard deviation S indicates the precision associated • with measurements generated by a group of laboratories. This represents the broad variation in the data collected in an inter!aboratory study. However, a measure of how well an Individual analyst can expect to perform in his own laboratory is another important measure of precision. This single-analyst precision, denoted by SR, was estimated for each Youden pair by 20 ------- sr ¦ Jx&Jii(Di ¦6,2 where m - the number of complete sets of Youden pair observations remaining after outliers have been removed, D-j - the difference between the observations in the ith Youden pair, D - average of the Dj values. The percent relative single-analyst standard deviation was calculated by %RSD-SR = p- x 100 where X is the average of the two mean recovery statistics corresponding to the two concentration levels defining the particular Youden pair. These summary statistics provide detailed Information on the accuracy and precision of the data obtained for each concentration level. One objective of the statistical analysis of the data is to summarize the information about accuracy and precision which is contained in the statistics. A systematic relationship often exists between the mean recovery (X) and the true concentration level (C) of the analyte in the sample. In addition, there are often systematic relationships between the precision statistics (S and SR) and the mean recovery (X). Usually these systematic relationships can be adequately approximated by a linear relationship (i.e., by a straight line). Once these straight lines are established, they can be used to conveniently summarize the behavior of the method within a water type, and they can aid in comparing the behavior of the method across water types. In addition they can be used to obtain estimates of the accuracy and precision at any concentration level within the applicable range studied. They can also be used to predict the behavior of the method when used under similar conditions. These important relationships are discussed below. STATEMENT OF METHOD ACCURACY The accuracy of the method is characterized by the relationship of the mean recovery (X) to the true concentration (C) of the analyte in the water sample. In order to obtain a mathematical expression for this relationship, a regression line of the form 21 ------- X = a + b • C (1) was fitted to the data by regression techniques The true concentration values often vary over a wide range. In such cases, the mean recovery statistics associated with the larger concentration values tend to dominate the fitted regression line producing relatively larger errors in the estimates of mean recovery at the lower concentration values. In order to eliminate this problem, a weighted least squares technique was used to fit the mean recovery data to the true concentration values. The weighted least square technique was performed by dividing both sides of Equation (1) by C resulting in Equation (2) (2) The {X/C/ values were regressed against the (1/C) values using ordinatory least squares to obtain .estimates for the values of a and b. (This is equivalent to performing a weighted least squares with weights w = l/C^; see Reference 8, page 108 for details.) Equation (2) can easily be converted to the desired relationship given by Equation (1). The intercept (b) from Equation (2) becomes the slope (b) for Equation (1) and the slope (a) from Equation (2) becomes the intercept (a) for Equation (1). Equation (1) can be used to calculate the percent recovery over the applicable range of concentrations used in the study. The percent recovery is given by a + b • Percent Recovery ¦[* x 100 - £ + b x 100 (3) If the absolute value of the ratio (a/C) is small relative to the slope (b) for concentration in the low end of the range of concentration levels used in the study, then the percent recovery can be approximated by b x 100. For example, suppose the true concentration values range from 25 ug/L to 515 ug/L, the fitted line is given by X = 0.20 + 0.85 * C. The percent recovery would be approximated by (0.85) x 100 = 85% over the specified range of 25 ug/L to 515 ug/L. If the ratio (a/C) is not small relative to the slope (b), then the percent recovery depends upon the true concentration (C), and it must be evaluated at each concentration value within the specified range. 22 ------- STATEMENT OF METHOD PRECISION The precision of the method is characterized by the relationships between precision statistics (S and SR) and mean recovery (X). In order to obtain a mathematical expression for these relationships, regression lines of the form S = d + e • X (4) and SR - f. + g ¦ X* (5) were fitted to the data. As discussed previously with respect to accuracy, the values of X and X* often vary over a wide range. In such cases the standard deviation statistics associated with the larger mean recovery values will dominate the regression lines. This will produce relatively larger errors 1n the estimates of S and SR at the lower mean recovery values. Therefore, a weighted least squares technique was also used to establish the values of the parameters d, e, f and g in Equations (4) and (5). The weighted least squares technique was performed by dividing both sides of Equation (4) by X* resulting in Equation (6) \| = d • + e (6) and by dividing both sides of Equation (5) by X* resulting in Equation (7) f • h + g (n The {S/X} values were regressed against the {1/X} values and the {SR/X) values were regressed against the 1/X values using ordinary least squares to obtain estimates for the parameters d, e, f and g. Equations (4) and (5) were obtained from Equations (6) and (7) 1n a manner similar to that discussed for mean recovery. The slope (d) for Equation (6) 1s the Intercept (d) for Equation (4), and the intercept (e) for Equation (6) is the slope (e) for Equation (4). Similarly, the slope 23 ------- (f) for Equation (7) is the Intercept (f) for Equation (5), and the intercept (g) for Equation (7) 1s the slope (g) for Equation (5). Given Equations (4) and (5), the percent relative overall standard deviation and the percent relative single-analyst standard deviation are respectively. If the absolute value of the ratio (d/X) is small relative to the slope (e)# then the percent relative overall standard deviation can be approximated by (e x 100) over the applicable range of mean recovery values. Similarly if the ratio (f/X) is small relative to the slope (g), then the percent relative single-analyst standard deviation can be approximated by (g x 100) over the applicable range of mean recovery values. If the ratios (d/X and f/X) are not small relative to the slopes (e) and (f), then the percent relative standard deviations depend upon the values of the mean recovery statistics X and X, and they should be evaluated separately for each value of X and X. COMPARISON OF ACCURACY AND PRECISION ACROSS WATER TYPES It is possible that the accuracy and precision of Method 608 depend upon the type of water being analyzed. The summary statistics X, S and SR are calculated separately for each concentration level within each water type. They can be compared across water types in order to obtain information about the effects of water type on accuracy and precision. However, the use of these summary statistics in this manner has several disadvantages. First, it is cumbersome since there are 36 mean recovery statistics (X) (six concentrations x six waters), 36 percent statistics (S) and 18 precision statistics (SR) calculated for each compound. Comparison of these statistics across concentration levels and across water types becomes unwieldly. Second, the statistical properties of this type of comparisons procedure are difficult to determine. Finally, due to variation associated with X, S and SR, comparisons based on these statistics can lead to inconsistent conclusions about the effect of water type. For example, distilled water may produce a significantly lower value (8) and (9) 24 ------- than surface water for the precision statistic S at a high concentration, but a significantly higher value for S at a low concentration. An alternative approach, described in detail in Reference [9], has been developed to test for the effects of water type. This alternative approach is based on the concept of summarizing the average effect of water- type across concentration levels rather than studying the local effects at each concentration level* If significant differences are established by this alternative technique, then the summary statistics can be used for* further local analysis. The test for the effect of.water type is based on the following statistical model. If X-jdenotes the measurement reported by laboratory i for water type j and ampule k, then The model components Sj and Yj are fixed parameters which determine the effect of water type j on the behavior the observed measurements fX-j^}. The parameter is the true concentration level associated with ampule k. The model component L-\ is a random factor which accounts for the systematic error associated with laboratory i- The model component ^ the rand°m factor which accounts for the within laboratory error. The model is designed to approximate the global behavior of the data. The multiplicative structure was chosen because of two important properties. First, it allows for a possible curvilinear relationship between the data and the true concentration level C\|< through the use of the exponent Yj on C^. This makes the model more flexible in comparison to straight line models. Second, as will be seen below, there is an inherent increasing relationship between the variability in the data and the concentration level in this model. This property is important because it is typical of tnterlaboratory data collected under conditions where the true concentration levels vary widely. Accuracy is related directly to the mean recovery or expected value of the measurements {X-jj^}. The expected value for the data modeled by Equation (10) is ijk " Bj ^k^ " Li ' Gijk i = 1,2, ...,n j - 1,2,...,6 k = 1,2,,6 (10) »• ~ • > E(Xijk) = Bj * CkYj * E(L1 • Eijk) (11) 25 ------- Precision is related to the variability 1n the measurements The variance of the data modeled by Equation (10) is VartXijk) - Bj CkYJ 2 Var(Li • eijk) (12) which 1s an increasing function of C\|<. The effect of water type on the accuracy and.precision of Method 608 is determined by the values of the parameters (pj) and {yj> in Equations (11) and (12). If the {6j} and {yj} vary with j (i.e., vary across water type), then the accuracy and precision of the method also vary across water type. In order to determine if these parameters do vary across water type and to compare their values, they must be estimated from the laboratory data using regression techniques. Equation (10) represents the basic model. However, taking natural logarithms of both sides of Equation (10), the following straight line regression model is obtained, in Xjjk = in Bj + yj in un Lj + in (13) which can be analyzed using standard linear model analysis techniques. The parameter in Bj is the intercept and Yj the slope of the regression line associated with water type j. It is assumed that in L-j is normally distributed with mean 0 and variance a? and that in e^j^ is normally distributed with mean 0 and variance c* and that the {in L-j} and (n Gjjk} terms are independent. Based on Equation (13) the comparison of water types reduces to the comparison of straight lines. Distilled water is viewed as a control, and each of the remaining lines is compared directly to the line for distilled water. Using the data on the log-log scale and regression techniques, the parameters in Bj (and hence Bj) and Yj can be estimated. The estimates are then used to test the null hypothesis that there 1s no effect due to water- type. The formal null and alternative statistical hypotheses Hq and are given by Hq: in Bj - in Bi = 0 and Yj - Yj = 0 for j = 2,3,4,5,6 26 ------- versus Ha; Jin Bj - xn 61 f 0 and/or Yj - Yi ^ 0 for some j = 2,3,4,5,6 The test of null hypothesis Hq against the alternative hypothesis is based on an F-statistic derived from standard linear model theory. The probability of obtaining a value of an F-statistic as large as the value which was actually observed (F OBS), denoted by P(F > F OBS), is calculated under the assumption that Hq is true. The null hypothesis Hq is rejected in favor of if P(F > F OBS) is less than 0-05. If Hq is rejected, then some linear combination of the differences in Bj - in Bi and yj - is statistically different from zero. However, this does not guarantee there will be a statistically significant direct effect attributable to any specific water type since the overall F test can be overly sensitive to minor systematic effects common to several water- types. The effect due to water type is judged to be statistically significant only if one of the differences in Bj - in Bi and/or yj - yj is statistically different from zero. This is determined by checking the simultaneous 95% confidence intervals which are constructed for each of these differences. Each true difference can be stated to lie within its respective confidence interval with 95% confidence. If zero is contained within the confidence interval, then there is no evidence that the corresponding difference is significantly different from zero. If at least one of the confidence intervals for the differences in Bj - in Bi or yj - yj fails to include zero, then the statistical significance of the effect due to water type has been established. However, establishment of a statistically significant effect due to water- type does not necessarily mean that the effect is of practical importance. Practical importance is related to the size and interpretation of the difference. The interpretation of the differences involves comparing the mean recovery and standard deviation of the (X-jj^) data for each water type to the mean recovery and standard deviation obtained for distilled water. These comparisons are made on a relative basis. The mean recovery for water type j is given by Equation (11) ~ The mean recovery for water type j is compared to that for distilled water (jcl) on a relative basis by E(Xiik) Bj Ck-'j E(L, • eijk) _ 0i „ Y._Yi ck^E(Li ..em)-BTCk J 1 (14> 27 ------- [The ratio of the standard deviations would be equivalent to Equation (14) and therefore the interpretation of the effect on precision 1s the same as that for the effect on mean recovery.] The ratio in Equation (14) is a measure of the relative difference in mean recovery between water type j and distilled water. It is composed of two parts (a) 8j/8i, which is independent of the true concentration level (i.e., the constant bias) and (b) which depends upon the true concentration level (i.e., the concentration dependent bias). If Yj - y\ is zero, then the relative difference in mean recovery is just 8j/8i which is independent of concentration level C^. It can then be stated that the mean recovery of water type j is (8j/8i) x 100% of the mean recovery for distilled water. If Yj - Yj is not zero, then the mean recovery of water- type j is [ (Bj/Bi) • C\|< YJ-yl) x 100% of that for distilled water and therefore depends upon the true concentration level C^. In order to illustrate these points consider the following example. Suppose that a significant F-value has been obtained and the confidence intervals for all the differences contain zero except for water type 5. For water type 5, the point estimate for in B5 - Jin 81 is -0.38 and the confidence interval for An 65 - in 81 is (-0.69, -0.07). The point estimate for Y5 - Yi is 0.07, and the confidence interval for Y5 - Yj is (-0.04, 0.18). In this case a statistically significant effect due to water type has been established which involves only water type 5. The practical significance of this effect is judged by considering Equation (14). The ratio of mean recoveries for water type 5 and distilled water is given by Since the confidence interval for Y5 - Yj contains zero this difference is assumed to be insignificant and is set to zero. Therefore, Equations (15) and (16) reduce to 85/81. The point estimate for Jin 85 - n 6 was -0.38. Therefore, the point estimate for 85/81 is 0.68, and the mean recovery for water type 5 is estimated to be 68% of the mean recovery for distilled water. Similarly the standard deviation for the data for water type 5 is E(x15k) _ £5 = if Ck^l (15) and the ratio of the standard deviations is given by (16) 28 ------- estimated to be 68% of the standard deviation for distilled water. Since the 95% confidence interval for in 65 - in 81 was (-0.69, -0.07), any value in the interval (0.50, 0.93) is a reasonable estimate for 85/81, and the mean recovery (standard deviation) for water type 5 can be claimed to be from 50% to 93% of the mean recovery (standard deviation) for distilled •water. The practical significance of the effect due to water type 5 would depend upon the importance of a mean recovery (standard deviation) which is between 50% and 93% of the mean recovery (standard deviation) observed for distilled water. The comparison of accuracy and precision across water types just discussed is based on the assumption that Equation (10) approximately models the data. It is clear that in practical monitoring programs of this type such models cannot model the data completely in every case. This analysis, therefore, is viewed as a screening procedure which identifies those cases where differences in water types are likely to be present. A more detailed, local analysis can then be pursued using the basic summary statistics for precision and accuracy. 29 ------- SECTION 5 RESULTS AND CONCLUSIONS There was a high rejection rate for the data submitted on this study, ranging from 17,6% of the Aroclor 1254 data to 33.8% of the endosulfan sulfate results- These rejections include missing data, data reported as less than some value, rejection of entire sets of data, and statistical outliers rejected according to the criteria stated earlier. Overall, 12,898 values were not included or 25.4% of all data requested. The summary statistics obtained from the collaborative study data are presented in Tables 3 through 26 for the substances studied. Discussion of the accuracy, precision, and consistency across water types is presented separately in the following sections. ACCURACY OF THE METHOD The accuracy of the method is presented in terms of linear regression equations between the true dosing level and the mean recovered amount. The recovery that can be expected for the 24 substances under study is illustrated in Table 27. For this example, the midranges of the concentrations used in this study were inserted into the regression equations and the predicted concentration expressed as a percentage of the midrange. These predicted recoveries at the midrange provide a basis for comparing the recoveries across wastewaters and among substances. Recoveries at other concentrations would vary due to the relative impact of the slope and the intercept of the regression line upon the calculated result. The substances can be logically divided into three groups: single- compound pesticides, multiple-compound pesticides, and PCB formulations. The recoveries for the single-compound pesticides ranged from a low of 62% to a high of 101% for the first five water types and from 27 to 68% in the sixth water type, industrial effluent 3. The lower recovery from industrial effluent 3 was expected due to the severe emulsion that forms with this effluent, however, and roughly equivalent recoveries were obtained for the study substances from this matrix. There was low recovery 30 ------- TABLE 3.

The multiple-compound pesticides, chlordane and toxaphene, had midrange recoveries ranging from 80 to 86%'for the first four.water types, 73 and 74% from industrial effluent 2, and 42 and 43% from industrial effluent 3. The midrange recoveries for the PCB formulations ranged from 69 to 101% across the first five matrices and from 48 to 59% from industrial effluent 3. PRECISION OF THE METHOD The precision of the method is estimated by calculating regression equations for the precision components versus the mean recovery. In each case, the overall standard deviation (S) and single-analyst standard deviation (SR) have been expressed in terms of relative standard deviations at the midrange concentration for illustration purposes. These are shown in Tables 28 and 29, respectively. The overall relative standard deviations are reasonably consistent over the first five water types and higher in industrial effluent 3 for all three groupings of substances. The higher standard de-viations in industrial effluent 3 result from the varying ability of the analysts to deal with the emulsion. The overall relative standard deviation at the midrange was from 16 to 45, 19 to 36, and 14 to 40% for single-compound pesticides, multiple-compound pesticides, and PCB formulations, respectively, for the first five matrices. In the third effluent, they ranged from 26 to 91, 43 to 44 and 36 to 55% for the three groups, respectively. The single-analyst standard deviations were consistent with the overall results. For these, the ranges were 11 to 33, 10 to 31, and 12 to 28%, respectively, for the single-compound pesticides, multiple-compound pesticides and PCB formulations in the first five waters. In the sixth water, industrial effluent 3, the ranges were 13 to 58, 24 to 33, and 17 to 43%, respectively. COMPARISON ACROSS WATER TYPES The summaries of the effect of water type on the results obtained are presented in Tables B-l through B-24. A significant F-statistic was obtained on all of the substances studied. Inspection of the contrasts of the waters versus the laboratory pure water revealed that the only significant effect was the difference in intercept, or recovery, between 56 ------- TABLE 28.

The conclusion from this evaluation is that the variability among analyses was equivalent across all water types studied and that the accuracy was equivalent in five of the six waters. It should be noted, however, that the industrial effluents were selected on the basis of a low background of interfering compounds and as such do not represent wastewaters in general. METHOD EVALUATION The accuracy of the method as determined from the collaborative study data can be compared to the results obtained during the development study on methodology [10]. In the wastewater application phase of that program, data were obtained on five industrial effluents, three of which were similar in character to those used in this study, i.e., provi di ng a 1 ow background of interfering compounds. These are identified as wastewaters 1, 3, and 4 in that report. For purposes of discussion, the study compounds can be classified into three groupings: single-compound pesticides, multiple-compound pesticides, and PCB formulations. In the previous work, performed by a single laboratory, recoveries of the single-compound pesticides were generally near 100%, with ranges of 91 to 100, 79 to 102, and 82 to 101 for the three similar wastewaters. In this study, the recoveries were similar for industrial effluent 1 (68 to 101), slightly lower for industrial effluent 2 (62 to 90), and lower for industrial effluent 3 (27 to 68). The results for industrial effluent 3 were consistent with the preliminary evaluation of this matrix by this laboratory, however, in which recoveries were consistently obtained near the 60% level. Lower average recoveries were obtained on the multiple- compound pesticides, around 80% for industrial effluents 1 and 2 and 34 and 54% for industrial effluent 3 compared to recoveries at or above 90% in the previous study. For the Aroclor formulations, the results were similar to the developmental work. In the previous study, the recovery of the Aroclors ranged from 92 to 104 and 92 to 103 in two of the wastewaters, and a recovery of 99% was obtained for Aroclor 1254 in the third, the only formulation tested in that matrix. While the range of values was wider (81 to 100 and 72 to 93) in industrial effluents 1 and 2, percent recoveries in the high 80s and low 90s were common. In industrial effluent 3, recoveries of 48 to 59% were obtained, which represented the levels expected from this effluent in normal performance of the method. - 59 ------- In a previous study, method detection limit (MDL) was determined for 18 of the 24 substances in interference-free water (IFW) and for 15 of the 24 substances in two industrial effluents, using a procedure specified by the Environmental Monitoring and Support Laboratory. In this procedure, at least seven sample replicates containing the compounds at concentrations near the estimated detection limit of each were analyzed by Method 608. The standard deviation of the replicate measurements was calculated and multiplied by the Student's t value appropriate for a 99% confidence level with n-1 degrees of freedom (3.143 for seven replicates) to give the MDL value. The MDL values obtained are given in Table 30. Also shown in Table 30 for easy comparisons with the MDLs are the lowest concentrations used in the interlaboratory study. Due to circumstances which could not be controlled, it was necessary to choose the spiking concentrations (Youden pairs) used in the interlaboratory study before the MDL studies were completed. As a consequence, the spiking concentrations in industrial effluent 1 (the water with the highest background) were either lower or higher than would have been chosen, in some instances, if the MDL data had been available before concentrations were selected. For example, the spiking concentrations for y-BHC and heptachlor are, respectively, only 1.7 and 1.3 times the MDL values, but the spiking concentration for endosulfan II is 252 times the MDL figure. In most instances, however, the ratio of spiking concentration to MDL value lies between 5 and 100, which is considered an acceptable range. In any event, the results obtained in the study are not adversely affected by the several extreme ratios noted above. In conjunction with the MDL determinations, analytical curves for the single-compound pesticides, chlordane, toxaphene, and Aroclor 1242 were determined from duplicate sample analyses at five concentration levels chosen in conference with the project officer. Essentially linear responses were observed for all of the substances except e-BHC, endosulfan I, toxaphene, and Aroclor 1242. At concentrations within the ranges used in the interlaboratory study, the nonlinear responses of these four substances could significantly affect the results obtained unless the analyst constructed his calibration curves precisely or diluted the extracts, before analysis, to a point within the linear segment of the analytical curve. For these four substances, the response factor obtained at the low end of the concentration range could have diminished at the upper end by as much as 20% for B-BHC, 10% for endosulfan I, 20 to 25% for toxaphene, and 30 to 35% for Aroclor 1242. However, the recovery data for the three concentration levels studied show similar values, indicating that 60 ------- TABLE 30.

The most frequently mentioned trouble spot in the method involved the Kuderna-Danish apparatus. The temperatures given in the method were found to be too low to accomplish the concentration steps in the prescribed time, and most analysts who reported this problem had not given sufficient importance to the description in the method that the balls in the Snyder condenser would actively chatter at the proper boiling rate. Several participants lost samples rather consistently through "explosions" due to the sudden vaporization of a superheated portion of the extract. This occurred in some instances with enough violence to break the glass apparatus. An instruction is needed in the method as to where and how fast heat should be applied to the Kuderna-Danish apparatus. Several participants found the phrase "when the apparent volume of the liquid reaches 1 mL" ambiguous. What was meant by this phrase was that the final volume should be the apparent volume of 1 mL, at bath temperature, in the concentrator collection tube plus the liquid and uncondensed vapor in the flask and condenser amounting to a final volume, at room temperature, of about 5 mL. To achieve a final volume of 1 mL at room temperature, as some did, probably caused excessive losses in the concentration step. Excessive losses may have occurred, also, when some analysts maintained the stated bath temperatures for several hours in order to achieve adequate concentration. In order to do this, they had to ignore the estimated elapsed times given in the method for satisfactory concentration. The Florisil cleanup step proved troublesome to several analysts who reported that they could not recover the substances from the column as stated in Method 608, using the elution mixtures and volumes given. These problems could result from a variety of indiscretions: failure to use PR grade Florisil, failure to heat the Florisil as prescribed, failure to use the Florisil immediately after removal from the oven, failure to use a column of the proper dimensions, failure to use proper drip rate, failure to use ethyl ether containing 2% ethyl alcohol, and failure to guard against evaporative losses after the elution mixtures are prepared. Admittedly this is a step requiring much care; however, when due care is exercised, previous experience at this laboratory shows it to be very dependable and to give very reproducible results. The use of the mercury to rid extracts of elemental sulfur [11] was reported to be ineffective by a few participants. Our experience is that 62 ------- erratic results are sometimes encountered with its use but that it is better for general use with the large number of compounds involved in this study than are the known alternatives: acid-washed copper strips 112] and tetrabutylammonium sulfite reagent [13]. Other difficulties arose that could be problems associated with any interl aboratory study of any analytical method- Some particiants prepared standards inaccurately, performed calculations incorrectly, transposed digits, and at least two participants submitted data summary sheets for substances other than the ones given in the headings on the sheets. Participants were invited to provide comments about Method 608. Many comments were releated to the trouble areas mentioned previously. Some of the comments pertaining to other aspects are interesting from their human as well as technical content. For example: 1. The method is too labor intensive. 2. Better quality control should be specified. 3. It is a good state-of-the-art method. 4. Spiking concentrations were inappropriately high with respect to what would be expected in wastewaters. 5. The atmospheric pollution from all of the Kuderna-Da ni sh evaporations across the country is unacceptable. 6. Should correct results by applying recovery factors. 7. Should incorporate internal standards which elute in the fractions taken from the Florisil column. 8. Should give more detailed instructions, especially on how to preserve standard solutions. 9. Recommend different solvents, different analytical column. 10. The method is complete, concise, lucid, and relatively simple to follow. 63 ------- REFERENCES 1.

Scope and Application 1.1 This method covers the determination of certain organochlorine pesticides and polychlorinated biphenyls fPC3s). The foPowing parameters may be determined by this method: Parameter STOSET No. Parameter STORET No. Aldrin 3933D Endrin 39390 a-BHC 39337 Endrin Aldehyde 34366 b-BHC 39335 Heptachlor 39410 d-BHC 3934D Heotach1or Epoxide 39420 g-BHC 34259 Toxaphene 394D0 Chlordane 39350 PCB-1016 34571 4,4 ' -DDD 39310, PC3-1221 39488 4,4'-DDE 39320 PC8-1232 39492 4 4'-DOT 39300 PCB-1242 39496 0 i e1dr i n 39380 PCB-1248 39500 Endosulfan I 34361 PCB-1254 39504 Endosulfan II 34356 PCB-1260 39508 Endosulfan Sulfate 34351 1.2 This method is applicable to the determination of these compounds in municipal and industrial discharges. It is designed to be used to meet the monitoring requirements of the National Pollutant Discharge Elimination System (NPDES). As such, it p-esupposes a 161 ------- high expectation of finding the specific compounds of interest. If the user is attempting to screen samples for any or all of the compounds above, he must develop Independent protocols for the verification of Identity. 1.3 The sensitivity of this method is usually dependent upon the level of interferences rather than instrumental limitations. The limits of detection listed in Table I represent sensitivities that can be achieved In wastewaters. 1.4 This method 1s recorrmended for use only by experienced residue analysts or under the close supervision of such qualified persons. 2. Sumary of Method 2.1 A 1-liter sanple of wastewater is extracted with methylene chlor-lde using separatory funnel techniques. The extract is dried and concentrated to a volume of 10 ml or less. Chromatographic conditions are described which allow for the accurate measurement of the conpounds in the extract. 2.2 If interferences are encountered, the method provides selected general purpose cleanup procedures to aid the analyst in their elimination. 3. Interferences 3.1 Solvents, reagents, glassware, and other sample processing hardware may yield discrete artifacts and/or elevated baselines causing misinterpretation of gas chromatograms. An of these materials must be demonstrated to be free from Interferences under the conditions of the analysis by running method blanks. Specific selection of reagents and purification of solvents by destination 162 ------- In all-glass systems may be required. 3.2 Interferences coextracted from the samples will vary considerably from source to source, depending upon the diversity of the industrial complex or municipality being samoled. While general cleanup techniques are provided as part of this method, unique samples may require additional cleanup approaches to achieve the sensitivities stated in Table 1. 3.3 Glassware must be scrupulously clean. Clean as soon as possible after use by rinsing with the last solvent used. This should be followed by detergent washing in hot water. Rinse with tap water, distilled water, acetone and finally pesticide quality hexane. Heavily contaminated glassware may require treatment in a muffle furnace at 400°C for 15 to 30 minutes. Some high boiling materials, such as PCBs, may not be eliminated by this treatment. Volumetric ware should not be heated in a muffle furnace. Glassware should be stored immediately after drying or cooling to prevent any accumulation of dust or other contaminants. Store Inverted or capped with aluminum foil. 3.4 Interferences by phthalate esters can pose a problem in the 15X and 50X fractions from.the rlorfsll fractionation. These interferences can be minimized by avoiding contact with any plastic materials. The presence of phtha'ate esters is indicated in samples that respond to electron capture detectors but not to mlcrocoulonetric or electrolytic conductively (halogen mode) detectors. 4. Apparatus and Materials 4.1 Sampling equipment, for discrete or composite sampling. 163 ------- 4.1.1 Grab sample bottle - amber glass, liter or quart volume. . .. French or Boston Round design 1s recoimended. The container must be washed and solvent rinsed before use to minimize interferences. 4.1.2 Bottle caps - Threaded to screw on sample bottles. Caps must be lined with Teflon. Foil may be substituted if sample is not corrosive. 4.1.3 Compositing equipment - Automatic or manual compositing system. Must incorporate glass sample containers for the collection of a minimum of 250 ml. Sairple containers must be kept refrigerated during sampling. No tygon or rubber tubing or fittings may be used in the system. 4.2 Separatory funnel - 2000 ml* with Teflon stopcock. 4.3 Drying column - A 20 m ID pyrex chromatographic column w	------- 4.4.4 Boiling chips-extracted, approximately 10/40 mes... 4.5 Water bath - Heated, with concentric ring cover, capable of tenperature control (+ 2°C). The bath should be used in a hood. 4.6 Gas chromatoaraph - Analytical system complete with gas chromatograph. suitable for on-column injection and a'l required accesso^-'es including election capture or halogen-specific detector, column supplies, recorder, gases, syringes. A data system fo»- measuring peak areas is recommended. 4.7 Chromatographic column - Pyrex, 400 rm x 25 nm OD, with coarse fritted plate and Teflon stopcock (Kontes K-42054-213 or equivalent). 5. Reagents 5.1 Preservatives: 5.1.1 Sodium hydroxide - (ACS) 10 N in distilled water. 5.1.2 Sulfuric acid - (ACS) Mix equal vo1umes of conc. ^SO^ with distilled water. 5.2 Methylene chloride - Pesticide quaMty or equivalent. 5.3 Sodium Sulfate - (ACS) Granular, anhydrous (purified by heating at 400°C for 4 hrs.). 5.4 Stock standards - Prepare stock standard solutions at a concentration of 1.00 ug/ul by dissolving 0.100 grams of assayed reference material in pesticide quality isooctane or othe* appropriate solvent and diluting to volume in a 100 ml ground glass stoppered volumetric flask. The stock solution is transferred to ground glass stoppered reagent bottles, stored in a refrigerator, and checked frequently for signs of degradation or evaporation, 165 ------- especially just prior to preparing working standards from them. 5.5 Boiling chips, Hengar granules (Hengar Co.; Fisher Co.) or equivalent. 5.'6 Mercury, triple distilled. 5.7 Aluminum oxide, basic or neutral, active. 5.8 Hexane, oesticide residue analysis grade. 5.9 Isooctane (2,2,4-trimethyl pentane), pesticide residue analysis grade. 5.10 Acetone, pesticide residue analysis grade. 5.11 Diethyl ether, preserved with Zt ethanol. 5.11.1 Must be free of peroxides as indicated by EM quant test strips {EM Laboratories, Inc., 500 Executive Blvd., Elmsford, N.Y.. 10523^. 5.11.2 If test indicates, remove peroxides by eluting over basic or neutral grade aluminum oxide. Retest before using. 5.12 Florisil - PR grade (50/100 mesh); purchase activated at 1250°F and store in glass containers with glass stoppers or foi1-1ined screw caps. Before use activate each batch at least 16 hours at 130°C in a foil covered glass container. 6. Calibration 6.1 Prepare caMbration standards that contain the compounds of interest, either singly or mixed together. The standards should be prepared at concentrations covering two or more orders of magnitude that will completely bracket the working range of the chromatographic system. If the sensitivity of the detection system can be calculated from Table I as 100 ug/1 in the final extract, 166 ------- for exanple prepare standards at 10 ug/1, 50 ug/1, 100 ug/1, 500 ug/1, etc. so that injections of 1-5 ul of each calibration standard will define the linearity of the detector in the working range. 6.2 Asseirtle the necessary gas chromatographic apparatus and establish operating parameters equivalent to those indicated in Table I. 3y injecting calibration standards* establish the sensitivity limU of the detector and the linear range of the analytical system for each compound. 6.3 Before using any cleanup procedure, the analyst must process a se-ies of calibration standards through the system to validate elution patterns and the absence of interferences from the reagents. 7. Quality Control 7.1 Before processing any sanples, 'the analyst should demonstrate through the analysis of a distilled water method blank, that all glassware and reagents are interference-f^ee. Each time a set of samples is extracted or there is a change in reagents, a method blank should be processed as a safeguard against chronic laboratory contamination. 7.2 Standard quality assurance practices should be used with this method. Field replicates should be collected to validate the precision of the sarrpling technique. Laboratory -eplicates should be analyzed to validate the precision of the analysis. Fortified samples should be analyzed to validate the accuracy of the analysis. Where doubt exists over the identification of a peak on the ch~omatogram, confirmatory techniques such as mass spectroscopy 167 ------- should be used. Sample Collection, Preservation, and Handling 8.1 Grab samples must be collected 1n glass containers. Conventional sampling practices should be followed, except that the bottle must not be prewashed with sample before collection. Composite samples should be collected in refrigerated glass containers in accordance with the retirements of the program. Automatic sampling equipment must be free of tvgon and other potential sources of contamination. 8.2 The samples must be iced or refrigerated from the time of collection until extraction. Chemical preservatives should not be used in the field unless more than 24 hours will elapse before delivery to the laboratory. If the samples will not be extracted within 48 hours of collection, the sample should be adjusted to a pH range of 6.0-8.0 with sodium hydroxide or sulfuric add. 8.3 All samples must be extracted within 7 days and completely analyzed within 30 days of collection. Sample Extraction 9.1 Mark the water meniscus on the side of the sample bottle for later determination of sample volume. Pour the entire sample Into a two-liter separatory funnel. Check the pH with wide-range paper and adjust to within the range of 5-9 with sodium hydroxide or sulfuric acid. 9.2 Add 60 ml methylene chloride to the sanple bottle and shake 30 seconds to rinse the walls. Transfer the solvent into the separatory funnel, and extract the sanple by shaking the funnel for two minutes with periodic venting to release vapor pressure. Allow 168 ------- the organic layer to separate from the water phase for a minimum of ten minutes. If the emulsion interface between layers is more than one-third the size of the solvent layer, the analyst must emoloy mechanical techniques to complete the phase separation. The optimum technique depends upon the sample, but may include Stirring, filtration of the emulsion through glass wool, or centrifugation. Collect the methylene chloride extract in a 250-ml Ehrlenmeyer flask. 9.3 Add a second 60-ml volume of methylene chloride to the sample bottle and complete the extraction procedure a second time, combining the extracts in the Ehrlenmeyer flask. 9.4 Perform a third extraction in the same manner. Pour the combined extract through a drying column containing 3-4 inches of anhydrous sodium sulfate, and collect it in a 500-ml Kuderna-Danish (K-D) flask equipped with a 10 ml concentrator tube. Rinse the Ehrlenmeyer flask and column with 20-30 ml methylene chloride to complete the quantitative transfer. 9.5 Add 1-2 clean boiling chips to the flask and attach a three-ball Snyder column. Prewet the Snyder column by adding about 1 ml methylene chloride to the top. Place the K-D apparatus on a steaming hot (60-65°C) water bath so that the concentrator tube is partially immersed in the hot wate", and the entire lower rounded surface of the flask is bathed in steam. Adjust the verti- cal position of the apparatus and the water temperature as -equired to complete the concentration in 15-20 minutes. At the proper rate of distillation the balls of the column will actively chatter but 169 ------- the chanters will not flood. When the apparent volume of liquid reaches 1 ml, remove the K-D apparatus and allow it to drain for at least 10 minutes while cooling. 9.6 Increase the temperature of the hot water bath to about SO°C. Momentarily remove the Snyder column add 50 ml of hexane and a new boiling chip and reattach the Snyder column. Pour about 1 ml of hexane Into the top of the Snyder column and concentrate the sol- vent extract as before. Elapsed time of concentration should be 5 to '0 minutes. When the apparent volume of liquid reaches 1 ml, remove the K-D apparatus and allow it to drain at least 10 uinutes while cooling. Remove the Snyder column and rinse the flask and its lower joint into the concentrator tube with 1-2 ml of hexane» and adjust the volume to 10 ml. A 5-ral syringe is recommended for this operation. Stopper the concentrator tube and store refrige- rated 1f further processing will not be performed immediately. If the sample extract requires no further cleanup, proceed with gas chromatographic analysis. If the sample requires cleanup, proceed to 5ect1on 10. 9.7 Determine the original saiTple vo^me by refilling the sample bottle to the mark and transferring the liquid to a 1000 ml graduated cylinder. Record the sample volume to the nearest 5 ml. Cleanup and Separation 10.1 Cleanup procedures are used to extend the sensitivity of a method by minimizing or eliminating interferences that mask or otherwise disfigure the gas chromatographic response to the pesticides and 170 ------- PCB's. The Florisil column allows for a select fractionation of the compounds and will eliminate polar materials. Elemental sulfur interfere with the elect-on capture gas chromatography of certain pesticides and can be removed by the techniques described below. 10.2 Floris"' Co^mn Cleanup 10.2.1 Add a weight of Florisil, nominally 21g, but predetermined by calibration, to a chromatographic column. Settle the Florisil by tapping the column. Add sodium sulfate to the top of the Florisil to form a layer 1-2 cm deep. Add 60 ml of hexane to wet and rinse the sodium sulfate and Florist!. Just prio»- to exposure of the sodium sulfate to air, stop the draining of the hexane by closing the stopcock on the chromatog-aphy column. Discard the eluate. 10.2.2 Add the sample extract from the K-0 concentrator tube to the Florisil column. Rinse the tube twice with 1-2 ml hexane, adding each rinse to the column. 10.2.3 Place a 500 ml K-D flask and clean concentrate tube unde^ the chromatography column. Drain the column ------- elution patterns for the pesticides and PCB's are shown in Table II. 10.2.4 Concentrate the eluates by standard K-D techniques (9.5), substituting hexane for methylene chloride and using the water bath at about 85°C. Adjust final volume to 10 ml with hexane. Analyze by gas chromatography. 10.3 Elemental sulfur will usualty elute entirely in Fraction 1. To remove sulfur interference from this fraction or the c-'ginal extract, pipet 1.00 ml of the concentrated extract into a clean concentrator tube or Teflon-sealed vial. Add 1-3 drops of mercury and seal. Agitate the contents of the vial for 15-30 seconds. Place the vial in an upright position on a reciprocal laboratory shaker and shake for 2 hours. Analyze by gas chromatography. 11. Gas Chromatography 11.1 Table I summarizes some recoimended gas chromatographic column materials and operating-conditions for the instrument. Included in this table are estimated retention times and sensitivities that should be achieved by this method. Examples of the separations achieved by these columns are shown n Figures 1 through 10. Calibrate the system daily with a minimum of three injections of calibration standards. 11.2 Inject 2-5 ul of the sanple ext-act using the so^ent-flush technique. Smaller (1.0 ul^ volumes can be injected in automatic devices are errployed. Record the volume injected to the nearest 0.05 ul, and the resulting peak size, in area units. '1.3 If the peak area exceeds the linear range of the system, dilute the extract and reanalyze. 172 ------- U.4 If the peak area measurement 1s prevented by the presence of . Interferences, further cleanup 1s required. 12.

ABSTRACT
This report describes the results obtained and data analyses from an
Inter!aboratory study of EPA Method 608 (Organochlorine Pesticides and
PCBs). The method is designed to analyze for 16 single-compound
pesticides, chlordane, toxaphene, and seven Aroclor formulations in water
and wastewater. All were included in this study except endrin aldehyde,
sufficient quantities of which could not be obtained. As tested here, the
method utilizes three 60-mL extractions with dichloromethane, cleanup/
separation on a Florisil column, and injection into a gas chromatograph
equipped with an electron capture detector.
The study design required the analyst to dose six waters with eight
analytical groups, each at six levels. The six dosing levels of each
substance or combination represented three Youden pairs, one each at a low,
an intermediate, and a high level. The six waters used were a laboratory
pure water, a finished drinking water, and a surface water, collected by
the participant, and three low-background industrial effluents (SICs 2869,
2869, and 2621) provided by the prime contractor. A total of 22
laboratories participated in the study.
The method is assessed quantitatively with respect to the accuracy and
precision that can be expected. In addition, results of method detection
limit studies are included as are qualitative assessments of the method
based upon comments by the participating laboratories.
The work was performed between September 1978 to December 1981 under
Contract 68-03-2606.

SECTION 1
INTRODUCTION
EPA first promulgated guidelines [1] establishing test procedures for
the analysis of pollutants in 1973, following the passage of the Federal
Water Pollution Control Act in 1972 by Congress. Pursuant to the amendment
and publication of these guidelines, EPA entered into a Settlement
Agreement—the Consent Decree—which required the study and, if necessary,
regulation of 65 "priority" pollutants and classes of pollutants of known
or suspected toxicity to the biota. Subsequently, Congress passed the
Clean Water Act of 1977 [2], mandating the control of toxic pollutants
discharged into ambient waters by industry.
In order to facilitate the implementation of the Clean Water Act, EPA
selected 129 specific toxic pollutants, 113 organic and 16 inorganic, for
initial study. The organic pollutants were divided into 12 categories
based on their chemical structure. Analytical methods were developed by
EPA for these 12 categories through in-house and contracted research.
These analytical methods may eventually be required for the monitoring of
the 113 toxic pollutants in Industrial wastewater effluents, as specified
by the Clean Water Act of 1977.
As a logical subsequence to the work that produced proposed EPA Method
608 (Organochlorine Pesticides and PCBs) [3], an inter!aboratory study was
conducted to determine the precision and accuracy of the proposed method.
This report describes the work performed, presents the data acquired, and
gives the conclusions drawn from the collaborative effort.
Of the 25 priority pollutants named in Method 608, 24 were tested in
this study. Endrin aldehyde, which is included in Method 608, was
eliminated from this study because it could not be obtained in sufficient
quantity for the study, except through a costly synthesis effort. The 24
substances were handled in eight groups during the analytical
determinations in order to minimize the number of individual operations
that had to be performed. Even so, a very substantial effort had to be
made by each participating laboratory in order to perform the required
1

-------
analyses. The shortest period of performance recorded by any laboratory,
measured from the time samples were received and the complete data package
was submitted, was 3-1/2 months.
The eight groups of substances were as follows:
GROUP I
GROUP II
o-BHC
•0-BHC
6-BHC
Heptachlor epoxide

Endosulfan sulfate

The non-EPA laboratories participating in this study were the 20
lowest bidders from the list of qualifying laboratories that responded to
the request for bids. Qualifications were established based upon
information submitted by the laboratories. The laboratories were selected
to be typical of the laboratories that would utilize the method when it
went into widespread usage. The participating laboratories are listed in
Figure 1. The laboratories are identified by number in this report and no
correlation between the identifying number and the order of laboratories in
the list of participating laboratories should be presumed. The EPA
laboratories participating were on a voluntary basis.

SECTION 2
SUMMARY
As a result of the collaborative study conducted and the data
analysis, the following conclusions can be drawn concerning EPA Method 608
(Organochlorine Pesticides and PCBs).
The accuracy of the method could generally be expressed as a linear
function of the true concentration. The regression equations are
shown in Table 1.
•	The precision of the method could generally be expressed as a
linear function of the mean recovery. These regression equations
are also shown in Table 1.
•	Recoveries at the midrange concentration were similar to those
obtained during the developmental phase in many instances and
lower in others, indicating satisfactory method performance. The
recoveries ranged from 68 to 101% of for single-compound
pesticides, 73 to 86% for multiple-compound pesticides, and 69 to
101% for the PCB formulations in the first five matrices. Lower
recoveries were obtained in the third industrial effluent due to
emulsion formation. Eighty-six percent of the recoveries among
the first five matrices exceeded 80% and 12.5% exceeded 90%.
•	At the midrange concentration, overall percent relative standard
deviations of 12 to 45, 19 to 36 and 14 to 40% were obtained for
the above three groupings of compounds among the first five
matrices. The single-analyst percent relative standard deviations
were from 11 to 33, 10 to 31 and 12 to 28%, respectively, under
the same conditions. Poorer precision was obtained for industrial
effluent 3, as expected, due to its nature.
•	Six water types were used in this study: laboratory pure, finished
drinking, surface, and three industrial effluents. The only
significant difference among the results obtained was in the
recovery of the substances from the third industrial effluent.

This effluent gave a large emulsion on extraction that resulted in
lowered extraction efficiency- With one exception, there was no
detectable difference in precision among the results from the six
waters studied.
• The principal problem area noted by the participants was related to
the concentration of extracts with the Kuderna-Danish apparatus.

SECTION 3
DESCRIPTION OF STUDY
The study design was based on Youden's original plan [4] for
collaborative evaluation of precision and accuracy for analytical methods.
According to Youden's design, samples are analyzed in pairs, and each
sample of a pair has a slightly different concentration of the constituent.
The analyst is directed to do a single analysis and report one value for
each sample, as if for a normal, routine sample.
In this study, samples were prepared as concentrates in sealed glass
ampules and shipped to the analyst along with portions of final effluents
from manufacturing plants from three relevant Industries. Each
participating laboratory was responsible for supplying laboratory pure
water, finished water, and a surface water, thus giving a total of six
water matrices involved in the study. The analyst was required to add an
aliquot of each concentrate to a volume of water from each of the six
waters and submit the spiked water to analysis. Three pairs of samples
were used. One pair contained the substances at what was considered to be
equivalent to a low level for the industrial effluents; a second pair
contained the substances at an intermediate level and the third pair
contained the substances at a high level.
TEST DESIGN
A summary of the test design using Youden's nonreplicate technique for
x and y samples is given below:
1.	Three Youden pairs were used for each parameter with the
deviation from the mean of each pair being at least 5% but no
more than 20.
2.	The three Youden pairs were spread over a usable and realistic
range with the lowest level estimated to be near the detection
limit in industrial effluent with the highest background of
electron capture-sensitive substances.
3.	Analyses were performed in six waters. Three of the waters were
selected from relevant industries as determined by the
10

-------
information contained in a memorandum of December 29, 1978 from
M. Dean Neptune, Analytical Programs, Effluent Guidelines
Division, to R. B. Schaffer, Director, Effluent Guidelines
Division, through W. A. TelHard, Chief, Energy and Mining
Branch. Therefore, each participant was to generate 36 data
points for each substance.
4.	Two hundred eighty-eight samples (eight analytical groups x six
concentrations x six replicates) prepared as stable concentrates
in sealed glass ampules were shipped with approximately 61 liters
each of the three industrial effluents to 20 non-EPA laboratories
and to two EPA laboratories. The concentrations of substances in
the ampules were unknown to the participants.
5.	Each participant was supplied with a copy of Method 608 and
supplementary instructions relative to spiking procedure, cleanup
column to be used, GC column and detector to be used, and GC
injection technique.
6.	To commence an analysis, the analyst was instructed to open an
ampule, add 1 mL of concentrate to 1 L of water, and analyze per
instructions. .
7.	Each sample was to be analyzed once.
8.	Before the formal study began, each participant was sent a pair
of ampules (not one of the pairs used in the study) for a trial
analysis by Method 608. After submitting data from these
analyses to SwRI, participants met in Cincinnati to discuss and
resolve problems encountered during the trial run.
9.	Fifty ampules of each concentrate prepared were supplied to the
project officer.
PREPARATION OF SAMPLES, WASTEWATER SELECTION, AND PROCUREMENT
The pesticide and PCB substances used to prepare sample concentrates
were obtained from several commercial sources and from the Quality
Assurance Section, EPA, HERL, ETD, ACB (MD-69), Research Triangle Park,
North Carolina. Substances obtained from commercial sources were compared
to those from the EPA to establish that purity and GC profile, 1n the case
of multipeak substances, and were found to be satisfactory.
The detailed protocol for concentrate and ampule production was
reviewed and approved by the project officer before ampule production
11

-------
commenced. Salient points of the protocol are described in the following
paragraph.
Sample concentrates were prepared by dissolving precisely-weighed
(analytical balance) amounts in methyl alcohol or acetone in Class A
volunetric flasks. Where dilutions were required, Class A volumetric glass
pipettes were used to transfer the required volumes. The volumes
transferred were never less than 4 mL. Solutions were put into brown,
borosilicate ampules, chilled, and heat-sealed. All glassware had been
fired overnight at approximately 400°C before use. The sealed ampules were
stored in paperboard boxes at room temperature until shipped to
participants.
Before each concentrate was used to fill ampules, the concentration(s)
of substance(s) was compared with a standard that had been prepared from a
separate weighing of substance(s). Three ampules taken at random from the
ampules produced were checked against the same external standard mentioned
immediately above. These verification checks served to prevent gross
errors from being committed; the true values were assumed to be those
established by the weighing of substance for concentrate preparation. It
was rare to find-a verification analysis which deviated more than 5% from
the true value. The true values for all test substances are given in
Table 2.
One of the three wastewaters selected for use in the study was from a
pesticide plant (SIC 2869-industrial effluent 1), one from an organics and
plastics plant (SIC 2869-industrial effluent 2), and the third from a kraft
paper mill (SIC 2621-industrial effluent 3). Industrial effluent 1 had a
relatively high interference background; however, only two of the peaks
coeluted with standards--heptachl or and endosulfan II. The amounts
indicated were in the low parts per trillion range. Peaks eluting in the
first four minutes offered a good challenge to the detection of the lowest
Youden pair peaks in this area. Industrial effluent 2 offered low to
moderate interferences from substances that were not parameters under test.
Upon standing several months this water developed peaks that were strongly
suspected to be from elemental sulfur, causing mercury treatment of
extracts to be necessary in many instances. Industrial effluent 3 formed a
tenacious emulsion that required centrifugation to break. Even then, only
about 60% of the extracting solvent was usually recovered. Severe
Interferences from elemental sulfur peaks were present in the extracts but
these could be eliminated almost totally with mercury treatment.

The wastewaters were collected in 10-barrel (55-gallon untreated iron
drums) quantities and shipped to SwRI for reshipment to participants in
1-gallon glass containers obtained from Burdick and Jackson, Inc.
Industrial effluent 1 was not pooled before shipment but samples taken from
barrels 1, 5, and 10 gave chromatograms that were indistinguishable from
one another; therefore, homogeneity was assumed- Industrial effluents 2
and 3 were pooled in a 600-gallon tank before being put in bottles.
ANALYSIS AND REPORTING
In addition to admonitions to follow Method 608 procedure,
supplementary instructions were sent to participants at the time the trial
run ampules were shipped. Participants were advised how to dose the water,
to use only a Florisil cleanup column, and to make injections of extract
Into the GC using the solvent-flush technique described by Burke [5], if
manual injections were used. Only electron capture detectors were to be
used. Acceptable dose-response data for dieldrin were included as an aid
to determining the performance of an electron capture detector. Also, the
request was made that all pertinent GC recorder charts be sent with the
data submitted for the trial run and the formal tests to follow.
At the Cincinnati conference, trial run data were presented and a
step-by-step discussion of the method was given. The most common errors
(calculation, standards preparation, and improper expression of results)
were pointed out. At the meeting, the following supplementary instructions
were given:
1.	Column 1, as given in Method 608, and electron capture detectors
will be used by all participants.
2.	Quantitation of the multipeak substances will be left to the
discretion of the analyst with respect to the number of peaks
used and whether or not to average the values if more peaks than
one are followed in the analyses.
3.	The three fractions (6?, 15%, and 50% ethyl ether fractions) will
be separated on Florisil in the analyses of Groups I and II
during the analyses of all unspiked and spiked waters.
After the Cincinnati conference, a follow-up letter was sent to each
participant requesting that the example data calculation sheets and data
summary sheets that were enclosed be used during the study. The same
letter requested that the final report include information on the
following:
14

-------
1.	method of quantitating multipeak substances;
2.	sources of standards;
3.	source of surface water and the nature of any possible
contaminants;
4.	suggestions as to how Method 608 could be improved.
DISTRIBUTION OF SAMPLES
A single shipment of 288 ampules was made by overnight air express to
all laboratories. No instance of ampule breakage during shipment was
reported. However, some participants reported shortages or having received
empty, unbroken ampules and others accidentally broke ampules during the
study. Replacement ampules were provided in these cases.
The water matrices were also shipped by overnight air express, each
participant receiving 61 liters (16 gallons) of each of the three
industrial effluents. The time required to collect and distribute the
effluents was about six weeks. Only 2 gallons were reported to have been
broken in transit. Several gallons were broken or otherwise made unusable
through laboratory mishaps. Replacement shipments were made in these
instances.
Specifications within the scope of work required that concentrates for
spiking exhibit satisfactory stability for 45 days before the trial run
ampules could be sent out and for 90 days before shipments for the formal
study could commence. These milestones were passed without significant
difficulty. The stability measurements consisted of comparing the highest
level of the middle Youden pair against freshly prepared standards. Four
ampules were withdrawn at random at 0-, 45-, and 90-day periods.
Triplicate GC injections of the properly diluted content were made and the
average value obtained compared to the freshly prepared standards.
Deviations from the true value varied in a manner similar to that observed
during the verification analyses. Thus, stability was considered to be
satisfactory.
The solvent for all concentrations, except Group II, was methyl
alcohol. The solvent for Group II was acetone. These solvents were chosen
because of their hydrophilicity and satisfactory performance during
informal stability tests conducted earlier in the program. During these
tests the only unstable combinations noted were acetone-endosulfan sulfate
and methyl al cohol-endosul fan II. Thus, acetone was chosen for Group II
concentrates and methyl alcohol for the others.
15

-------
The unrefrigerated plant effluents remaining in reserve at SwRI were
periodically examined by extraction and GC injection. Industrial effluents
1 and 3 were not observed to change but industrial effluent 2 exhibited
what appeared to be typical sulfur peaks after standing for 2 months.
These peaks were reducible by applying the mercury cleanup treatment as
given in Method 608. Participants were advised by letter to be on the
lookout for such changes in the extract profile for industrial effluent 2
and to apply the mercury cleanup where the need was indicated.

SECTION 4
TREATMENT OF DATA
The objective of this interlaboratory study was to obtain information
about the accuracy and precision associated with measurements generated by
Method 608. This objective was met through the use of statistical analysis
techniques designed to extract and summarize the relevant information about
accuracy and precision from the data reported by the participating
laboratories. The statistical techniques employed in the data reduction
process are similar to the techniques suggested in the ASTM Standard
Practice D2777-77.
The algorithms required to perform the statistical analyses have been
integrated into a system of computer programs referred to as IMVS
(Interlaboratory Method Validation Study), The analyses performed by IMVS
[6] include several tests for the rejection of outliers (laboratories and
individual data points), summary statistics by concentration level for mean
recovery (accuracy), overall and single-analyst standard deviation
(precision), determination of the linear relationship between mean recovery
and concentration level, determination of the linear relationship between
the precision statistics and mean recovery, and a test for the effect of
water type on accuracy and precision.
A detailed description of each of the statistical analysis procedures
is presented below.
PREPROCESSING
An initial review of the data was performed to determine if a
systematic error was evident in the data that could be identified and
legitimately corrected prior to data analysis. Chromatograms and
supporting data were investigated to verify that the analyses were run
under the proper conditions and that calculations were accurate and
supportable. Where an anomaly existed, such as a series of results that
were different from the true values by one or more orders of magnitude, the
analyst was contacted, told that there was an apparent error, and asked to
check his values. No indication was given as to the nature of the
17

-------
inconsistency in order not to prejudice the results. If an error was
found, the corrected values were used in the data analyses. If the analyst
reported no error could be found, the data were allowed to stand as
reported.
All analyses reported as less than a detection limit and results that
the analysts noted as influenced by spillage or loss of sample were removed
from the data set prior to insertion into the computer program. The data
set thus prepared was utilized in the statistical analysis supplied by the
sponsor.
REJECTION OF OUTLIERS
Spurious data points are always a part of any set of data collected
during an interlaboratory test program. It is important to identify and
remove these data points because they can lead to values of summary
statistics which are not representative of the general behavior of the
method. However, some erratic behavior in the data may be directly related
to some facet of the method under the study. Therefore, spurious data
points should not be removed indiscriminantly, and any points that are
removed should be clearly identified since further investigation of the
analytical conditions related to the outliers might be of value. Data
rejected as outliers for this study as a result of any of the following
tests for outliers have been identified by the symbol in the raw data
tables.
YOUDEN'S LABORATORY RANKING PROCEDURE
In some cases the analytical values reported by a specific laboratory
are so consistently high or low that a large systematic error may be
attributed to that laboratory. These data are not representative of the
method and should be rejected. Youden's [4] ranking test for outlying
laboratories was applied separately to data from each of the waters used in
this study. Since six water types were used in this study, the laboratory
ranking procedure was applied to these six different subsets of the data.
Each laboratory ranking test was performed at the 5% level of significance.
The Youden laboratory ranking procedure requires a complete set of
data from every laboratory within a given water type. Missing data from
labortory i for water type j were replaced by the following procedure.
Letting X-jj^ denote the reported measurement from laboratory i for water
type j and concentration level it is assumed that
xijk = 3j'CkYj-Li-cijk
18

-------
where Bj and Yj are fixed parameters which determine the effect of water
type j, L-j is the systematic error due to laboratory i and c-fj^ is the
random within laboratory error. Taking natural logarithms, it follows that
in X i j ¦ Jin ^ Yj ^ ^ in ^ in £ j j|^
which is a linear regression model with dependent variable in X^ and
independent variable in C^. (Details and justification for this model are
discussed in the section "Comparison of Accuracy and Precision Across Water
Types.")
The natural logarithms of the individual laboratory's data were
regressed against the natural logarithms of the true concentration levels
for the six ampules in each water type. The predicted values in Xij^ were
obtained from the regression equation, and the missing values for X-jj^ were
estimated byT-jjk = exp(in Xi j^, where exp (c) denotes the constant e
raised to the c power.
If the ranking test rejected a laboratory for a specific water type,
then all of the laboratory data for that water type were rejected as
outliers. The rejected values were excluded from all the remaining
analyses. In addition, after completion of the laboratory ranking
procedure, the predicted values created to fill in for the missing data
were rejected and excluded from further analyses for all laboratories.
TESTS FOR INDIVIDUAL OUTLIERS
The data remaining after the laboratory ranking procedure were grouped
by water type. For each water type, the data were broken down into six
subsets defined by the six concentration levels (ampules) used in the
study. For each subset of the data, all missing, zero, "less than" and
"nondetect" data were rejected. Next, the test for individual outliers
constructed by Thompson [7] and suggested in the ASTM Standard Practice
D2777-77 was applied to the data using a 5% significance level. If an
individual data point was rejected based on this test, it was removed from
the subset, and the test was repeated using the remaining data in the
subset. This process was continued until no additional data could be
rejected.
STATISTICAL SlfftlARlES
Several summary statistics were calculated using the data remaining
for each concentration level after the outlier rejection tests were
19

-------
performed. These summary statistics include: the number of retained data
points, the mean recovery, accuracy as a percent relative error, the
absolute overall standard deviation, the percent relative overall standard
deviation, the absolute single-analyst standard deviation, and the percent
relative single-analyst standard deviation. The basic formulas used to
calculate these statistics are presented below where Xj, X£, Xn denote
the values of the n retained data points for a specific concentration
level.
Mean Recovery (X):
n
z
i=l
X = ± l Xi
The conventional notation for mean recovery is X; however the symbol X is
used in this report to be consistent with the output from the computer
program.
Accuracy as a % Relative Error:
X - True Value
WE - True Value x 100
Overall Standard Deviation:
S =
= $ m (Xi'x)2
and
Percent Relative Overall Standard Deviation:
*RSD = (|) x 100
The overall standard deviation S indicates the precision associated
•
with measurements generated by a group of laboratories. This represents
the broad variation in the data collected in an inter!aboratory study.
However, a measure of how well an Individual analyst can expect to perform
in his own laboratory is another important measure of precision. This
single-analyst precision, denoted by SR, was estimated for each Youden pair
by
20

-------
sr ¦ Jx&Jii(Di ¦6,2
where m - the number of complete sets of Youden pair observations
remaining after outliers have been removed,
D-j - the difference between the observations in the ith
Youden pair,
D - average of the Dj values.
The percent relative single-analyst standard deviation was calculated
by
%RSD-SR = p- x 100
where X* is the average of the two mean recovery statistics corresponding
to the two concentration levels defining the particular Youden pair.
These summary statistics provide detailed Information on the accuracy
and precision of the data obtained for each concentration level. One
objective of the statistical analysis of the data is to summarize the
information about accuracy and precision which is contained in the
statistics.
A systematic relationship often exists between the mean recovery (X)
and the true concentration level (C) of the analyte in the sample. In
addition, there are often systematic relationships between the precision
statistics (S and SR) and the mean recovery (X). Usually these systematic
relationships can be adequately approximated by a linear relationship
(i.e., by a straight line). Once these straight lines are established,
they can be used to conveniently summarize the behavior of the method
within a water type, and they can aid in comparing the behavior of the
method across water types. In addition they can be used to obtain
estimates of the accuracy and precision at any concentration level within
the applicable range studied. They can also be used to predict the
behavior of the method when used under similar conditions. These important
relationships are discussed below.
STATEMENT OF METHOD ACCURACY
The accuracy of the method is characterized by the relationship of the
mean recovery (X) to the true concentration (C) of the analyte in the water
sample. In order to obtain a mathematical expression for this
relationship, a regression line of the form
21

-------
X = a + b • C
(1)
was fitted to the data by regression techniques
The true concentration values often vary over a wide range. In such
cases, the mean recovery statistics associated with the larger
concentration values tend to dominate the fitted regression line producing
relatively larger errors in the estimates of mean recovery at the lower
concentration values. In order to eliminate this problem, a weighted least
squares technique was used to fit the mean recovery data to the true
concentration values. The weighted least square technique was performed by
dividing both sides of Equation (1) by C resulting in Equation (2)
(2)
The {X/C/ values were regressed against the (1/C) values using ordinatory
least squares to obtain .estimates for the values of a and b. (This is
equivalent to performing a weighted least squares with weights w = l/C^;
see Reference 8, page 108 for details.) Equation (2) can easily be
converted to the desired relationship given by Equation (1). The intercept
(b) from Equation (2) becomes the slope (b) for Equation (1) and the slope
(a) from Equation (2) becomes the intercept (a) for Equation (1). Equation
(1) can be used to calculate the percent recovery over the applicable range
of concentrations used in the study.
The percent recovery is given by
a + b •
Percent Recovery
¦[*
x 100 - £ + b
x 100	(3)
If the absolute value of the ratio (a/C) is small relative to the slope (b)
for concentration in the low end of the range of concentration levels used
in the study, then the percent recovery can be approximated by b x 100.
For example, suppose the true concentration values range from 25 ug/L to
515 ug/L, the fitted line is given by X = 0.20 + 0.85 * C. The percent
recovery would be approximated by (0.85) x 100 = 85% over the specified
range of 25 ug/L to 515 ug/L.
If the ratio (a/C) is not small relative to the slope (b), then the
percent recovery depends upon the true concentration (C), and it must be
evaluated at each concentration value within the specified range.
22

-------
STATEMENT OF METHOD PRECISION
The precision of the method is characterized by the relationships
between precision statistics (S and SR) and mean recovery (X). In order to
obtain a mathematical expression for these relationships, regression lines
of the form
S = d + e • X	(4)
and
SR - f. + g ¦ X*	(5)
were fitted to the data.
As discussed previously with respect to accuracy, the values of X and
X* often vary over a wide range. In such cases the standard deviation
statistics associated with the larger mean recovery values will dominate
the regression lines. This will produce relatively larger errors 1n the
estimates of S and SR at the lower mean recovery values. Therefore, a
weighted least squares technique was also used to establish the values of
the parameters d, e, f and g in Equations (4) and (5). The weighted least
squares technique was performed by dividing both sides of Equation (4) by
X* resulting in Equation (6)
| = d • + e	(6)
and by dividing both sides of Equation (5) by X* resulting in Equation (7)
f • h + g	(n
The {S/X} values were regressed against the {1/X} values and the
{SR/X*) values were regressed against the 1/X* values using ordinary least
squares to obtain estimates for the parameters d, e, f and g.
Equations (4) and (5) were obtained from Equations (6) and (7) 1n a
manner similar to that discussed for mean recovery. The slope (d) for
Equation (6) 1s the Intercept (d) for Equation (4), and the intercept (e)
for Equation (6) is the slope (e) for Equation (4). Similarly, the slope
23

-------
(f) for Equation (7) is the Intercept (f) for Equation (5), and the
intercept (g) for Equation (7) 1s the slope (g) for Equation (5).
Given Equations (4) and (5), the percent relative overall standard
deviation and the percent relative single-analyst standard deviation are
respectively. If the absolute value of the ratio (d/X) is small relative
to the slope (e)# then the percent relative overall standard deviation can
be approximated by (e x 100) over the applicable range of mean recovery
values. Similarly if the ratio (f/X*) is small relative to the slope (g),
then the percent relative single-analyst standard deviation can be
approximated by (g x 100) over the applicable range of mean recovery
values.
If the ratios (d/X and f/X*) are not small relative to the slopes (e)
and (f), then the percent relative standard deviations depend upon the
values of the mean recovery statistics X and X*, and they should be
evaluated separately for each value of X and X*.
COMPARISON OF ACCURACY AND PRECISION ACROSS WATER TYPES
It is possible that the accuracy and precision of Method 608 depend
upon the type of water being analyzed. The summary statistics X, S and SR
are calculated separately for each concentration level within each water
type. They can be compared across water types in order to obtain
information about the effects of water type on accuracy and precision.
However, the use of these summary statistics in this manner has several
disadvantages. First, it is cumbersome since there are 36 mean recovery
statistics (X) (six concentrations x six waters), 36 percent statistics (S)
and 18 precision statistics (SR) calculated for each compound. Comparison
of these statistics across concentration levels and across water types
becomes unwieldly. Second, the statistical properties of this type of
comparisons procedure are difficult to determine. Finally, due to
variation associated with X, S and SR, comparisons based on these
statistics can lead to inconsistent conclusions about the effect of water
type. For example, distilled water may produce a significantly lower value
(8)
and
(9)
24

-------
than surface water for the precision statistic S at a high concentration,
but a significantly higher value for S at a low concentration.
An alternative approach, described in detail in Reference [9], has
been developed to test for the effects of water type. This alternative
approach is based on the concept of summarizing the average effect of water-
type across concentration levels rather than studying the local effects at
each concentration level* If significant differences are established by
this alternative technique, then the summary statistics can be used for*
further local analysis.
The test for the effect of.water type is based on the following
statistical model. If X-jdenotes the measurement reported by laboratory
i for water type j and ampule k, then
The model components Sj and Yj are fixed parameters which determine the
effect of water type j on the behavior the observed measurements fX-j^}.
The parameter is the true concentration level associated with ampule k.
The model component L-\ is a random factor which accounts for the systematic
error associated with laboratory i- The model component ^ the rand°m
factor which accounts for the within laboratory error.
The model is designed to approximate the global behavior of the data.
The multiplicative structure was chosen because of two important
properties. First, it allows for a possible curvilinear relationship
between the data	and the true concentration level C|< through the use
of the exponent Yj on C^. This makes the model more flexible in comparison
to straight line models. Second, as will be seen below, there is an
inherent increasing relationship between the variability in the data and
the concentration level in this model. This property is important
because it is typical of tnterlaboratory data collected under conditions
where the true concentration levels vary widely.
Accuracy is related directly to the mean recovery or expected value of
the measurements {X-jj^}. The expected value for the data modeled by
Equation (10) is
*ijk " Bj * ^k^ " Li ' Gijk
i = 1,2, ...,n
j - 1,2,...,6
k = 1,2,,6
(10)
»• ~ • >
E(Xijk) = Bj * CkYj * E(L1 • Eijk)
(11)
25

-------
Precision is related to the variability 1n the measurements
The variance of the data modeled by Equation (10) is
VartXijk) - Bj CkYJ 2 Var(Li • eijk)	(12)
which 1s an increasing function of C|<.
The effect of water type on the accuracy and.precision of Method 608
is determined by the values of the parameters (pj) and {yj> in Equations
(11) and (12). If the {6j} and {yj} vary with j (i.e., vary across water
type), then the accuracy and precision of the method also vary across water
type.
In order to determine if these parameters do vary across water type
and to compare their values, they must be estimated from the laboratory
data using regression techniques. Equation (10) represents the basic
model. However, taking natural logarithms of both sides of Equation (10),
the following straight line regression model is obtained,
in Xjjk = in Bj + yj in un Lj + in	(13)
which can be analyzed using standard linear model analysis techniques. The
parameter in Bj is the intercept and Yj the slope of the regression line
associated with water type j. It is assumed that in L-j is normally
distributed with mean 0 and variance a? and that in e^j^ is normally
distributed with mean 0 and variance c* and that the {in L-j} and (*n
Gjjk} terms are independent.
Based on Equation (13) the comparison of water types reduces to the
comparison of straight lines. Distilled water is viewed as a control, and
each of the remaining lines is compared directly to the line for distilled
water.
Using the data on the log-log scale and regression techniques, the
parameters in Bj (and hence Bj) and Yj can be estimated. The estimates are
then used to test the null hypothesis that there 1s no effect due to water-
type. The formal null and alternative statistical hypotheses Hq and are
given by
Hq: in Bj - in Bi = 0 and Yj - Yj = 0 for j = 2,3,4,5,6
26

-------
versus
Ha; Jin Bj - xn 61 f 0 and/or Yj - Yi ^ 0 for some j = 2,3,4,5,6
The test of null hypothesis Hq against the alternative hypothesis
is based on an F-statistic derived from standard linear model theory. The
probability of obtaining a value of an F-statistic as large as the value
which was actually observed (F OBS), denoted by P(F > F OBS), is calculated
under the assumption that Hq is true. The null hypothesis Hq is rejected
in favor of if P(F > F OBS) is less than 0-05.
If Hq is rejected, then some linear combination of the differences
in Bj - in Bi and yj - is statistically different from zero. However,
this does not guarantee there will be a statistically significant direct
effect attributable to any specific water type since the overall F test can
be overly sensitive to minor systematic effects common to several water-
types. The effect due to water type is judged to be statistically
significant only if one of the differences in Bj - in Bi and/or yj - yj is
statistically different from zero. This is determined by checking the
simultaneous 95% confidence intervals which are constructed for each of
these differences. Each true difference can be stated to lie within its
respective confidence interval with 95% confidence. If zero is contained
within the confidence interval, then there is no evidence that the
corresponding difference is significantly different from zero.
If at least one of the confidence intervals for the differences
in Bj - in Bi or yj - yj fails to include zero, then the statistical
significance of the effect due to water type has been established.
However, establishment of a statistically significant effect due to water-
type does not necessarily mean that the effect is of practical importance.
Practical importance is related to the size and interpretation of the
difference.
The interpretation of the differences involves comparing the mean
recovery and standard deviation of the (X-jj^) data for each water type to
the mean recovery and standard deviation obtained for distilled water*.
These comparisons are made on a relative basis. The mean recovery for
water type j is given by Equation (11) ~ The mean recovery for water type j
is compared to that for distilled water (jcl) on a relative basis by
E(Xiik) Bj Ck-'j E(L, • eijk) _ 0i „ Y._Yi
ck^E(Li ..em)-BTCk J 1	(14>
27

-------
[The ratio of the standard deviations would be equivalent to Equation (14)
and therefore the interpretation of the effect on precision 1s the same as
that for the effect on mean recovery.]
The ratio in Equation (14) is a measure of the relative difference in
mean recovery between water type j and distilled water. It is composed of
two parts (a) 8j/8i, which is independent of the true concentration level
(i.e., the constant bias) and (b)	which depends upon the true
concentration level (i.e., the concentration dependent bias). If Yj - y\
is zero, then the relative difference in mean recovery is just 8j/8i which
is independent of concentration level C^. It can then be stated that the
mean recovery of water type j is (8j/8i) x 100% of the mean recovery for
distilled water. If Yj - Yj is not zero, then the mean recovery of water-
type j is [ (Bj/Bi) • C|< YJ-yl) x 100% of that for distilled water and
therefore depends upon the true concentration level C^.
In order to illustrate these points consider the following example.
Suppose that a significant F-value has been obtained and the confidence
intervals for all the differences contain zero except for water type 5.
For water type 5, the point estimate for in B5 - Jin 81 is -0.38 and the
confidence interval for An 65 - in 81 is (-0.69, -0.07). The point
estimate for Y5 - Yi is 0.07, and the confidence interval for Y5 - Yj is
(-0.04, 0.18). In this case a statistically significant effect due to
water type has been established which involves only water type 5. The
practical significance of this effect is judged by considering Equation
(14). The ratio of mean recoveries for water type 5 and distilled water is
given by
Since the confidence interval for Y5 - Yj contains zero this difference is
assumed to be insignificant and is set to zero. Therefore, Equations (15)
and (16) reduce to 85/81. The point estimate for Jin 85 - *n 6* was -0.38.
Therefore, the point estimate for 85/81 is 0.68, and the mean recovery for
water type 5 is estimated to be 68% of the mean recovery for distilled
water. Similarly the standard deviation for the data for water type 5 is
E(x15k) _ £5
= if Ck^l
(15)
and the ratio of the standard deviations is given by
(16)
28

-------
estimated to be 68% of the standard deviation for distilled water. Since
the 95% confidence interval for in 65 - in 81 was (-0.69, -0.07), any value
in the interval (0.50, 0.93) is a reasonable estimate for 85/81, and the
mean recovery (standard deviation) for water type 5 can be claimed to be
from 50% to 93% of the mean recovery (standard deviation) for distilled
•water. The practical significance of the effect due to water type 5 would
depend upon the importance of a mean recovery (standard deviation) which is
between 50% and 93% of the mean recovery (standard deviation) observed for
distilled water.
The comparison of accuracy and precision across water types just
discussed is based on the assumption that Equation (10) approximately
models the data. It is clear that in practical monitoring programs of this
type such models cannot model the data completely in every case. This
analysis, therefore, is viewed as a screening procedure which identifies
those cases where differences in water types are likely to be present. A
more detailed, local analysis can then be pursued using the basic summary
statistics for precision and accuracy.

SECTION 5
RESULTS AND CONCLUSIONS
There was a high rejection rate for the data submitted on this study,
ranging from 17,6% of the Aroclor 1254 data to 33.8% of the endosulfan
sulfate results- These rejections include missing data, data reported as
less than some value, rejection of entire sets of data, and statistical
outliers rejected according to the criteria stated earlier. Overall,
12,898 values were not included or 25.4% of all data requested.
The summary statistics obtained from the collaborative study data are
presented in Tables 3 through 26 for the substances studied. Discussion of
the accuracy, precision, and consistency across water types is presented
separately in the following sections.
ACCURACY OF THE METHOD
The accuracy of the method is presented in terms of linear regression
equations between the true dosing level and the mean recovered amount. The
recovery that can be expected for the 24 substances under study is
illustrated in Table 27. For this example, the midranges of the
concentrations used in this study were inserted into the regression
equations and the predicted concentration expressed as a percentage of the
midrange. These predicted recoveries at the midrange provide a basis for
comparing the recoveries across wastewaters and among substances.
Recoveries at other concentrations would vary due to the relative impact of
the slope and the intercept of the regression line upon the calculated
result.
The substances can be logically divided into three groups: single-
compound pesticides, multiple-compound pesticides, and PCB formulations.
The recoveries for the single-compound pesticides ranged from a low of 62%
to a high of 101% for the first five water types and from 27 to 68% in the
sixth water type, industrial effluent 3. The lower recovery from
industrial effluent 3 was expected due to the severe emulsion that forms
with this effluent, however, and roughly equivalent recoveries were
obtained for the study substances from this matrix. There was low recovery

for heptachlor from industrial effluent 3, 27% at the midrange, with no
apparent explanation available.
The multiple-compound pesticides, chlordane and toxaphene, had
midrange recoveries ranging from 80 to 86%'for the first four.water types,
73 and 74% from industrial effluent 2, and 42 and 43% from industrial
effluent 3. The midrange recoveries for the PCB formulations ranged from
69 to 101% across the first five matrices and from 48 to 59% from
industrial effluent 3.
PRECISION OF THE METHOD
The precision of the method is estimated by calculating regression
equations for the precision components versus the mean recovery. In each
case, the overall standard deviation (S) and single-analyst standard
deviation (SR) have been expressed in terms of relative standard deviations
at the midrange concentration for illustration purposes. These are shown
in Tables 28 and 29, respectively.
The overall relative standard deviations are reasonably consistent
over the first five water types and higher in industrial effluent 3 for all
three groupings of substances. The higher standard de-viations in
industrial effluent 3 result from the varying ability of the analysts to
deal with the emulsion. The overall relative standard deviation at the
midrange was from 16 to 45, 19 to 36, and 14 to 40% for single-compound
pesticides, multiple-compound pesticides, and PCB formulations,
respectively, for the first five matrices. In the third effluent, they
ranged from 26 to 91, 43 to 44 and 36 to 55% for the three groups,
respectively.
The single-analyst standard deviations were consistent with the
overall results. For these, the ranges were 11 to 33, 10 to 31, and 12 to
28%, respectively, for the single-compound pesticides, multiple-compound
pesticides and PCB formulations in the first five waters. In the sixth
water, industrial effluent 3, the ranges were 13 to 58, 24 to 33, and 17 to
43%, respectively.
COMPARISON ACROSS WATER TYPES
The summaries of the effect of water type on the results obtained are
presented in Tables B-l through B-24. A significant F-statistic was
obtained on all of the substances studied. Inspection of the contrasts of
the waters versus the laboratory pure water revealed that the only
significant effect was the difference in intercept, or recovery, between

the laboratory pure water and industrial effluent 3 for 15 of the 24
substances studied.
The conclusion from this evaluation is that the variability among
analyses was equivalent across all water types studied and that the
accuracy was equivalent in five of the six waters. It should be noted,
however, that the industrial effluents were selected on the basis of a low
background of interfering compounds and as such do not represent
wastewaters in general.
METHOD EVALUATION
The accuracy of the method as determined from the collaborative study
data can be compared to the results obtained during the development study
on methodology [10]. In the wastewater application phase of that program,
data were obtained on five industrial effluents, three of which were
similar in character to those used in this study, i.e., provi di ng a 1 ow
background of interfering compounds. These are identified as wastewaters
1, 3, and 4 in that report. For purposes of discussion, the study
compounds can be classified into three groupings: single-compound
pesticides, multiple-compound pesticides, and PCB formulations.
In the previous work, performed by a single laboratory, recoveries of
the single-compound pesticides were generally near 100%, with ranges of 91
to 100, 79 to 102, and 82 to 101 for the three similar wastewaters. In
this study, the recoveries were similar for industrial effluent 1 (68 to
101), slightly lower for industrial effluent 2 (62 to 90), and lower for
industrial effluent 3 (27 to 68). The results for industrial effluent 3
were consistent with the preliminary evaluation of this matrix by this
laboratory, however, in which recoveries were consistently obtained near
the 60% level. Lower average recoveries were obtained on the multiple-
compound pesticides, around 80% for industrial effluents 1 and 2 and 34 and
54% for industrial effluent 3 compared to recoveries at or above 90% in the
previous study.
For the Aroclor formulations, the results were similar to the
developmental work. In the previous study, the recovery of the Aroclors
ranged from 92 to 104 and 92 to 103 in two of the wastewaters, and a
recovery of 99% was obtained for Aroclor 1254 in the third, the only
formulation tested in that matrix. While the range of values was wider (81
to 100 and 72 to 93) in industrial effluents 1 and 2, percent recoveries in
the high 80s and low 90s were common. In industrial effluent 3, recoveries
of 48 to 59% were obtained, which represented the levels expected from this
effluent in normal performance of the method. -
59
-------
In a previous study, method detection limit (MDL) was determined for
18 of the 24 substances in interference-free water (IFW) and for 15 of the
24 substances in two industrial effluents, using a procedure specified by
the Environmental Monitoring and Support Laboratory. In this procedure, at
least seven sample replicates containing the compounds at concentrations
near the estimated detection limit of each were analyzed by Method 608.
The standard deviation of the replicate measurements was calculated and
multiplied by the Student's t value appropriate for a 99% confidence level
with n-1 degrees of freedom (3.143 for seven replicates) to give the MDL
value. The MDL values obtained are given in Table 30. Also shown in Table
30 for easy comparisons with the MDLs are the lowest concentrations used in
the interlaboratory study. Due to circumstances which could not be
controlled, it was necessary to choose the spiking concentrations (Youden
pairs) used in the interlaboratory study before the MDL studies were
completed. As a consequence, the spiking concentrations in industrial
effluent 1 (the water with the highest background) were either lower or
higher than would have been chosen, in some instances, if the MDL data had
been available before concentrations were selected. For example, the
spiking concentrations for y-BHC and heptachlor are, respectively, only 1.7
and 1.3 times the MDL values, but the spiking concentration for endosulfan
II is 252 times the MDL figure. In most instances, however, the ratio of
spiking concentration to MDL value lies between 5 and 100, which is
considered an acceptable range. In any event, the results obtained in the
study are not adversely affected by the several extreme ratios noted above.
In conjunction with the MDL determinations, analytical curves for the
single-compound pesticides, chlordane, toxaphene, and Aroclor 1242 were
determined from duplicate sample analyses at five concentration levels
chosen in conference with the project officer. Essentially linear
responses were observed for all of the substances except e-BHC, endosulfan
I, toxaphene, and Aroclor 1242. At concentrations within the ranges used
in the interlaboratory study, the nonlinear responses of these four
substances could significantly affect the results obtained unless the
analyst constructed his calibration curves precisely or diluted the
extracts, before analysis, to a point within the linear segment of the
analytical curve. For these four substances, the response factor obtained
at the low end of the concentration range could have diminished at the
upper end by as much as 20% for B-BHC, 10% for endosulfan I, 20 to 25% for
toxaphene, and 30 to 35% for Aroclor 1242. However, the recovery data for
the three concentration levels studied show similar values, indicating that

problems associated with the nonlinearity of response of these substances
were handled in an effective way by the participating analysts.
The most frequently mentioned trouble spot in the method involved the
Kuderna-Danish apparatus. The temperatures given in the method were found
to be too low to accomplish the concentration steps in the prescribed time,
and most analysts who reported this problem had not given sufficient
importance to the description in the method that the balls in the Snyder
condenser would actively chatter at the proper boiling rate. Several
participants lost samples rather consistently through "explosions" due to
the sudden vaporization of a superheated portion of the extract. This
occurred in some instances with enough violence to break the glass
apparatus. An instruction is needed in the method as to where and how fast
heat should be applied to the Kuderna-Danish apparatus.
Several participants found the phrase "when the apparent volume of the
liquid reaches 1 mL" ambiguous. What was meant by this phrase was that the
final volume should be the apparent volume of 1 mL, at bath temperature, in
the concentrator collection tube plus the liquid and uncondensed vapor in
the flask and condenser amounting to a final volume, at room temperature,
of about 5 mL. To achieve a final volume of 1 mL at room temperature, as
some did, probably caused excessive losses in the concentration step.
Excessive losses may have occurred, also, when some analysts maintained the
stated bath temperatures for several hours in order to achieve adequate
concentration. In order to do this, they had to ignore the estimated
elapsed times given in the method for satisfactory concentration.
The Florisil cleanup step proved troublesome to several analysts who
reported that they could not recover the substances from the column as
stated in Method 608, using the elution mixtures and volumes given. These
problems could result from a variety of indiscretions: failure to use PR
grade Florisil, failure to heat the Florisil as prescribed, failure to use
the Florisil immediately after removal from the oven, failure to use a
column of the proper dimensions, failure to use proper drip rate, failure
to use ethyl ether containing 2% ethyl alcohol, and failure to guard
against evaporative losses after the elution mixtures are prepared.
Admittedly this is a step requiring much care; however, when due care is
exercised, previous experience at this laboratory shows it to be very
dependable and to give very reproducible results.
The use of the mercury to rid extracts of elemental sulfur [11] was
reported to be ineffective by a few participants. Our experience is that
62
-------
erratic results are sometimes encountered with its use but that it is
better for general use with the large number of compounds involved in this
study than are the known alternatives: acid-washed copper strips 112] and
tetrabutylammonium sulfite reagent [13].
Other difficulties arose that could be problems associated with any
interl aboratory study of any analytical method- Some particiants prepared
standards inaccurately, performed calculations incorrectly, transposed
digits, and at least two participants submitted data summary sheets for
substances other than the ones given in the headings on the sheets.
Participants were invited to provide comments about Method 608. Many
comments were releated to the trouble areas mentioned previously. Some of
the comments pertaining to other aspects are interesting from their human
as well as technical content. For example:
1.	The method is too labor intensive.
2.	Better quality control should be specified.
3.	It is a good state-of-the-art method.
4.	Spiking concentrations were inappropriately high with respect to
what would be expected in wastewaters.
5.	The atmospheric pollution from all of the Kuderna-Da ni sh
evaporations across the country is unacceptable.
6.	Should correct results by applying recovery factors.
7.	Should incorporate internal standards which elute in the
fractions taken from the Florisil column.
8.	Should give more detailed instructions, especially on how to
preserve standard solutions.
9.	Recommend different solvents, different analytical column.
10. The method is complete, concise, lucid, and relatively simple to
follow.

1.2 This method is applicable to the determination of these compounds
in municipal and industrial discharges. It is designed to be used
to meet the monitoring requirements of the National Pollutant
Discharge Elimination System (NPDES). As such, it p-esupposes a
161
-------
high expectation of finding the specific compounds of interest. If
the user is attempting to screen samples for any or all of the
compounds above, he must develop Independent protocols for the
verification of Identity.
1.3	The sensitivity of this method is usually dependent upon the level
of interferences rather than instrumental limitations. The limits
of detection listed in Table I represent sensitivities that can be
achieved In wastewaters.
1.4	This method 1s recorrmended for use only by experienced residue
analysts or under the close supervision of such qualified persons.
2.	Sumary of Method
2.1	A 1-liter sanple of wastewater is extracted with methylene chlor-lde
using separatory funnel techniques. The extract is dried and
concentrated to a volume of 10 ml or less. Chromatographic
conditions are described which allow for the accurate measurement
of the conpounds in the extract.
2.2	If interferences are encountered, the method provides selected
general purpose cleanup procedures to aid the analyst in their
elimination.
3.	Interferences
3.1 Solvents, reagents, glassware, and other sample processing hardware
may yield discrete artifacts and/or elevated baselines causing
misinterpretation of gas chromatograms. An of these materials
must be demonstrated to be free from Interferences under the
conditions of the analysis by running method blanks. Specific
selection of reagents and purification of solvents by destination
162
-------
In all-glass systems may be required.
3.2	Interferences coextracted from the samples will vary considerably
from source to source, depending upon the diversity of the
industrial complex or municipality being samoled. While general
cleanup techniques are provided as part of this method, unique
samples may require additional cleanup approaches to achieve the
sensitivities stated in Table 1.
3.3	Glassware must be scrupulously clean. Clean as soon as possible
after use by rinsing with the last solvent used. This should be
followed by detergent washing in hot water. Rinse with tap water,
distilled water, acetone and finally pesticide quality hexane.
Heavily contaminated glassware may require treatment in a muffle
furnace at 400°C for 15 to 30 minutes. Some high boiling
materials, such as PCBs, may not be eliminated by this treatment.
Volumetric ware should not be heated in a muffle furnace.
Glassware should be stored immediately after drying or cooling to
prevent any accumulation of dust or other contaminants. Store
Inverted or capped with aluminum foil.
3.4	Interferences by phthalate esters can pose a problem in the 15X and
50X fractions from.the rlorfsll fractionation. These interferences
can be minimized by avoiding contact with any plastic materials.
The presence of phtha'ate esters is indicated in samples that
respond to electron capture detectors but not to mlcrocoulonetric
or electrolytic conductively (halogen mode) detectors.
4. Apparatus and Materials
4.1 Sampling equipment, for discrete or composite sampling.
163
-------
4.1.1	Grab sample bottle - amber glass, liter or quart volume. .
.. French or Boston Round design 1s recoimended. The
container must be washed and solvent rinsed before use to
minimize interferences.
4.1.2	Bottle caps - Threaded to screw on sample bottles. Caps
must be lined with Teflon. Foil may be substituted if
sample is not corrosive.
4.1.3	Compositing equipment - Automatic or manual compositing
system. Must incorporate glass sample containers for the
collection of a minimum of 250 ml. Sairple containers
must be kept refrigerated during sampling. No tygon or
rubber tubing or fittings may be used in the system.
4.2	Separatory funnel - 2000 ml* with Teflon stopcock.
4.3	Drying column - A 20 m ID pyrex chromatographic column w

-------
4.4.4 Boiling chips-extracted, approximately 10/40 mes...
4.5	Water bath - Heated, with concentric ring cover, capable of
tenperature control (+ 2°C). The bath should be used in a hood.
4.6	Gas chromatoaraph - Analytical system complete with gas
chromatograph. suitable for on-column injection and a'l required
accesso^-'es including election capture or halogen-specific
detector, column supplies, recorder, gases, syringes. A data
system fo»- measuring peak areas is recommended.
4.7	Chromatographic column - Pyrex, 400 rm x 25 nm OD, with coarse
fritted plate and Teflon stopcock (Kontes K-42054-213 or
equivalent).
5. Reagents
5.1	Preservatives:
5.1.1	Sodium hydroxide - (ACS) 10 N in distilled water.
5.1.2	Sulfuric acid - (ACS) Mix equal vo1umes of conc.
^SO^ with distilled water.
5.2	Methylene chloride - Pesticide quaMty or equivalent.
5.3	Sodium Sulfate - (ACS) Granular, anhydrous (purified by heating at
400°C for 4 hrs.).
5.4	Stock standards - Prepare stock standard solutions at a
concentration of 1.00 ug/ul by dissolving 0.100 grams of assayed
reference material in pesticide quality isooctane or othe*
appropriate solvent and diluting to volume in a 100 ml ground glass
stoppered volumetric flask. The stock solution is transferred to
ground glass stoppered reagent bottles, stored in a refrigerator,
and checked frequently for signs of degradation or evaporation,
165

-------
especially just prior to preparing working standards from them.
5.5 Boiling chips, Hengar granules (Hengar Co.; Fisher Co.) or
equivalent.
5.'6 Mercury, triple distilled.
5.7	Aluminum oxide, basic or neutral, active.
5.8	Hexane, oesticide residue analysis grade.
5.9	Isooctane (2,2,4-trimethyl pentane), pesticide residue analysis
grade.
5.10	Acetone, pesticide residue analysis grade.
5.11	Diethyl ether, preserved with Zt ethanol.
5.11.1	Must be free of peroxides as indicated by EM quant test
strips {EM Laboratories, Inc., 500 Executive Blvd.,
Elmsford, N.Y.. 10523^.
5.11.2	If test indicates, remove peroxides by eluting over basic or
neutral grade aluminum oxide. Retest before using.
5.12	Florisil - PR grade (50/100 mesh); purchase activated at 1250°F
and store in glass containers with glass stoppers or foi1-1ined
screw caps. Before use activate each batch at least 16 hours at
130°C in a foil covered glass container.
6. Calibration
6.1 Prepare caMbration standards that contain the compounds of
interest, either singly or mixed together. The standards should be
prepared at concentrations covering two or more orders of magnitude
that will completely bracket the working range of the
chromatographic system. If the sensitivity of the detection system
can be calculated from Table I as 100 ug/1 in the final extract,
166

-------
for exanple prepare standards at 10 ug/1, 50 ug/1, 100 ug/1, 500
ug/1, etc. so that injections of 1-5 ul of each calibration
standard will define the linearity of the detector in the working
range.
6.2	Asseirtle the necessary gas chromatographic apparatus and establish
operating parameters equivalent to those indicated in Table I. 3y
injecting calibration standards* establish the sensitivity limU of
the detector and the linear range of the analytical system for each
compound.
6.3	Before using any cleanup procedure, the analyst must process a
se-ies of calibration standards through the system to validate
elution patterns and the absence of interferences from the reagents.
7. Quality Control
7.1	Before processing any sanples, 'the analyst should demonstrate
through the analysis of a distilled water method blank, that all
glassware and reagents are interference-f^ee. Each time a set of
samples is extracted or there is a change in reagents, a method
blank should be processed as a safeguard against chronic laboratory
contamination.
7.2	Standard quality assurance practices should be used with this
method. Field replicates should be collected to validate the
precision of the sarrpling technique. Laboratory -eplicates should
be analyzed to validate the precision of the analysis. Fortified
samples should be analyzed to validate the accuracy of the
analysis. Where doubt exists over the identification of a peak on
the ch~omatogram, confirmatory techniques such as mass spectroscopy
167

-------
should be used.
Sample Collection, Preservation, and Handling
8.1	Grab samples must be collected 1n glass containers. Conventional
sampling practices should be followed, except that the bottle must
not be prewashed with sample before collection. Composite samples
should be collected in refrigerated glass containers in accordance
with the retirements of the program. Automatic sampling equipment
must be free of tvgon and other potential sources of contamination.
8.2	The samples must be iced or refrigerated from the time of
collection until extraction. Chemical preservatives should not be
used in the field unless more than 24 hours will elapse before
delivery to the laboratory. If the samples will not be extracted
within 48 hours of collection, the sample should be adjusted to a
pH range of 6.0-8.0 with sodium hydroxide or sulfuric add.
8.3	All samples must be extracted within 7 days and completely analyzed
within 30 days of collection.
Sample Extraction
9.1	Mark the water meniscus on the side of the sample bottle for later
determination of sample volume. Pour the entire sample Into a
two-liter separatory funnel. Check the pH with wide-range paper
and adjust to within the range of 5-9 with sodium hydroxide or
sulfuric acid.
9.2	Add 60 ml methylene chloride to the sanple bottle and shake 30
seconds to rinse the walls. Transfer the solvent into the
separatory funnel, and extract the sanple by shaking the funnel for
two minutes with periodic venting to release vapor pressure. Allow
168

-------
the organic layer to separate from the water phase for a minimum of
ten minutes. If the emulsion interface between layers is more than
one-third the size of the solvent layer, the analyst must emoloy
mechanical techniques to complete the phase separation. The
optimum technique depends upon the sample, but may include
Stirring, filtration of the emulsion through glass wool, or
centrifugation. Collect the methylene chloride extract in a 250-ml
Ehrlenmeyer flask.
9.3	Add a second 60-ml volume of methylene chloride to the sample
bottle and complete the extraction procedure a second time,
combining the extracts in the Ehrlenmeyer flask.
9.4	Perform a third extraction in the same manner. Pour the combined
extract through a drying column containing 3-4 inches of anhydrous
sodium sulfate, and collect it in a 500-ml Kuderna-Danish (K-D)
flask equipped with a 10 ml concentrator tube. Rinse the
Ehrlenmeyer flask and column with 20-30 ml methylene chloride to
complete the quantitative transfer.
9.5	Add 1-2 clean boiling chips to the flask and attach a three-ball
Snyder column. Prewet the Snyder column by adding about 1 ml
methylene chloride to the top. Place the K-D apparatus on a
steaming hot (60-65°C) water bath so that the concentrator tube
is partially immersed in the hot wate*", and the entire lower
rounded surface of the flask is bathed in steam. Adjust the verti-
cal position of the apparatus and the water temperature as -equired
to complete the concentration in 15-20 minutes. At the proper rate
of distillation the balls of the column will actively chatter but
169

-------
the chanters will not flood. When the apparent volume of liquid
reaches 1 ml, remove the K-D apparatus and allow it to drain for at
least 10 minutes while cooling.
9.6	Increase the temperature of the hot water bath to about SO°C.
Momentarily remove the Snyder column* add 50 ml of hexane and a new
boiling chip and reattach the Snyder column. Pour about 1 ml of
hexane Into the top of the Snyder column and concentrate the sol-
vent extract as before. Elapsed time of concentration should be 5
to '0 minutes. When the apparent volume of liquid reaches 1 ml,
remove the K-D apparatus and allow it to drain at least 10 uinutes
while cooling. Remove the Snyder column and rinse the flask and
its lower joint into the concentrator tube with 1-2 ml of hexane»
and adjust the volume to 10 ml. A 5-ral syringe is recommended for
this operation. Stopper the concentrator tube and store refrige-
rated 1f further processing will not be performed immediately. If
the sample extract requires no further cleanup, proceed with gas
chromatographic analysis. If the sample requires cleanup, proceed
to 5ect1on 10.
9.7	Determine the original saiTple vo^me by refilling the sample bottle
to the mark and transferring the liquid to a 1000 ml graduated
cylinder. Record the sample volume to the nearest 5 ml.
Cleanup and Separation
10.1 Cleanup procedures are used to extend the sensitivity of a method
by minimizing or eliminating interferences that mask or otherwise
disfigure the gas chromatographic response to the pesticides and
170

-------
PCB's. The Florisil column allows for a select fractionation of
the compounds and will eliminate polar materials. Elemental sulfur
interfere with the elect-on capture gas chromatography of certain
pesticides and can be removed by the techniques described below.
10.2 Floris"' Co^mn Cleanup
10.2.1	Add a weight of Florisil, nominally 21g, but predetermined
by calibration, to a chromatographic column. Settle the
Florisil by tapping the column. Add sodium sulfate to the
top of the Florisil to form a layer 1-2 cm deep. Add 60 ml
of hexane to wet and rinse the sodium sulfate and Florist!.
Just prio»- to exposure of the sodium sulfate to air, stop
the draining of the hexane by closing the stopcock on the
chromatog-aphy column. Discard the eluate.
10.2.2	Add the sample extract from the K-0 concentrator tube to the
Florisil column. Rinse the tube twice with 1-2 ml hexane,
adding each rinse to the column.
10.2.3	Place a 500 ml K-D flask and clean concentrate tube unde^
the chromatography column. Drain the column 
-------
elution patterns for the pesticides and PCB's are shown in Table II.
10.2.4 Concentrate the eluates by standard K-D techniques (9.5),
substituting hexane for methylene chloride and using the
water bath at about 85°C. Adjust final volume to 10 ml
with hexane. Analyze by gas chromatography.
10.3 Elemental sulfur will usualty elute entirely in Fraction 1. To
remove sulfur interference from this fraction or the c-'ginal
extract, pipet 1.00 ml of the concentrated extract into a clean
concentrator tube or Teflon-sealed vial. Add 1-3 drops of mercury
and seal. Agitate the contents of the vial for 15-30 seconds.
Place the vial in an upright position on a reciprocal laboratory
shaker and shake for 2 hours. Analyze by gas chromatography.
11. Gas Chromatography
11.1	Table I summarizes some recoimended gas chromatographic column
materials and operating-conditions for the instrument. Included in
this table are estimated retention times and sensitivities that
should be achieved by this method. Examples of the separations
achieved by these columns are shown *n Figures 1 through 10.
Calibrate the system daily with a minimum of three injections of
calibration standards.
11.2	Inject 2-5 ul of the sanple ext-act using the so^ent-flush
technique. Smaller (1.0 ul^ volumes can be injected in automatic
devices are errployed. Record the volume injected to the nearest
0.05 ul, and the resulting peak size, in area units.
'1.3 If the peak area exceeds the linear range of the system, dilute the
extract and reanalyze.

15. SUPPLEMENTARY NOTES
16. ABSTRACT
This report describes the results obtained and data analysis from an interlabora-
tory evaluation of EPA Method 608 (Organochlorine Pesticides and'PCBs). The method
is desinned to analyze for 16 single-compound pesticides, chlordane, toxaphene, and
seven Aroclor formulations in water and wastewater. All were included in this study
except endrin aldehyde, sufficient quantities of which could not be obtained.
The study desinn required the analyst to dose six waters with eight analytical
oroups, each at six levels. The six dosing levels of each substance or combination
represented three Youden pairs, one each at a low, an intermediate, and a high level.
The six waters used were a laboratory pure water, a finished drinking water/and a
surface water, all collected by the participant, and three low-background industrial
effluents (SICs 2G69, 2869 and 2621). A total of 22 laboratories participated in the
study.
The method is assessed quantitatively with respect to the accuracy and precision
that can be expected. In addition, results of method detection limit studies are
included as are qualitative assessments of the method based upon comments by the
participating laboratories.
