The samples were analyzed according to criteria set forth in CLP SOW 2/88 (Rev. 5.89) for TCL Volatile target compounds on 11-07,08-90. The following is a summary of the QC results accompanying these sample results and a description of any problems encountered during their analysis:

1. Non-target compounds were not detected in these samples.

2. All surrogate recoveries were within EPA QC limits. 3. All water matrix spike recoveries were within EPA QC limits. Soil matrix spike and spike duplicate samples are associated with RFW lot 9010L363.

4. The laboratory blanks contained the common contaminant methylene chloride and acetone at levels less than 4x the CRQL.

5. Internal standard area were outside control limits for sample SMC-SD3-01. This sample was re-analyzed on 11-07-90 and similar results were obtained. Re-analysis results are available upon request.

1. Non-target compounds were detected in these samples.

2. One (1) of seventy-eight (78) surrogate recoveries was outside EPA QC. However, EPA CLP surrogate recovery criteria were met (i.e., no more than one outlier per fraction (acid and base neutral) and no recoveries less I-. than 10%). 3. Three (3) of twenty-two (22) water blank spike recoveries were outside EPA QC limits. All soil blank spike recoveries were within EPA QC limits. 1 4. Two (2) of twenty-two (22) soil matrix spike recoveries were outside EPA QC limits. 5. The laboratory blank 90LE1253-MBl contained i the common contaminant di-n-butylphthalate at a level less than the CRQL. I' 6. Internal standard areas are outside the control limits for samples SMC-SD1-01, SMC- SD4-01, SMC-RA-34-01 UPP, and SMC-RA-34-01-UPP MSD. The matrix spike analysis of sample SMC- I RA-34-01-UPP fulfilled the associated re- analysis requirements. The remaining samples were re-analyzed on 11-21-90 and similar I results were obtained. =-analysis results are available upon request.

WESTON, INC. LJ+J Lionville Laboratory CLIENT: TRC/SHIELD ALLOY SAMPLES RECEIVED: 10-30-90 RFW #: 9010L385 I PESTICIDE/PCB W.O. #: 2724-05-01 NARRATIVE The set of samples consisted of eight (8) soil samples and one (1) water sample collected on 10-30-90. The samples were extracted on 11-06,09-90 and analyzed according to criteria set forth in the Contract Laboratory Program for Pesticide and PCB target compounds on 12-06,07-90. The following is a summary of the QC results accompanying these sample results and a description of any problems encountered during their analysis:

1. Linearity and breakdown criteria were met on the primary column. Breakdown criteria for 4,4'-DDT is exceeded 12-07-90 at 21:20. There was no impact on this case because all sample extracts were analyzed prior to this evaluation standard. 2. Continuing calibration criteria were met for all compounds on at least one column for standards analyzed prior to the sample extracts.

3. Retention time criteria were met for all compounds on both the primary and confirmation columns,

4. One (1) nf sixteen (16) surrogate recoveries was outside EPA QC limits. The surrogate recovery for 90LE1274-MB1 BS (159%) exceeded the EPA QC limit of 150%. 5. The Pesticide Spiking Solution was inadvertently prepared at lox the usual concentrations of pesticides. The blank and matrix spike required a ten-fold dilution to maintain the pesticide concentrations within the linear range of the instrument. -2-

6. One (1) of seventeen (17) blank spike recoveries was outside EPA QC limits. The blank spike recovery for endrin was above EPA QC limits; which indicates the data could be biased high. There was no impact on the data, since this compound was not detected in the sample extracts.

7. Two (2) of twelve (12) matrix spike recoveries were outside EPA QC limits.

GLOSSARY OF PESTIPCB DATA

DATA OUALIFIERS U - Indicates that the compounds was analyzed for but not detected. The minimum detection limit for the sample (not the method detection limit) is reported with the U (e.g., IOU). J - Indicates an estimated value. This flag is used in cases where a target analyte is detected at a level 'less than the lower quantification level. If the limit - of quantification is 10 ug/L and a concentration of 3 ug/L is calculated, it is reported as 3J. B - This flag is used when the analyte is found in the associated blank as well as in the sample. It indicates possible/probable blank contamination. This flag is also used for a TIC as well as for a positively identified TCL compound. E - Indicates that the compound was detected beyond the calibration range and was subsequently analyzed at a dilution. I - Interfe-rence. ABBREVIATIONS BS - Indicates blank spike in which reagent grade water is spiked with the CLP matrix spiking solutions and carried through all the steps in the method. Spike recoveries are reported. BSD - Indicates blank spike duplicate. MS - Indicates matrix spike. MSD - Indicates matrix spike duplicate. DL - Indicates that recoveries were not obtained because the extract had to be diluted for analysis.

NA - Not applicable. DF - Dilution factor. NR - Not required. 1D CLIENT SAMPLE NO. PESTICIDE ORGANICS ANALYSIS SHEET I ISMC-RAf9-01-BCK Lab Name: Roy F. Weston, Inc. Work Order: 2724-05-01-0000 1

I: 2724-05-01 FARRATIVE The set of samples consisted of one (1) soil sample, one (2) sediment samples, and three (3) water samples coll2cted on 10-31-90. Thc samples were extracted on 11-06-90 and analyzed acccrding to criteria set forth in the Contract Laboratory Przgram for TCLP Pesticide and PCB target compounds on 12-06,07-90. Thc following is a summary of the QC results accompzzying these sample results and a description of any prc,rlems enzountered during their analysis:

1. Linearity and breakdown criteria were met on the primary column. Breakdown criteria for 4,4’-DDT were exceeded on 12-07-90 at 21:20. Matrix spike extracts of sample SMC-RA34-01- UPP were analyzed after this evaluation standard. It appears there was no impact on the spike recoveries.

2. Continuing calibration criteria were met for all compounds on at least one column for all standards. 3. Retention time criteria were met for all compounds on both the primary and confirmation columns.

4. All obtainable surrogate recoveries were within EPA QC limits. 5. All blank spike recoveries were within EPA QC limits.

9. Both arochlor 1254 and 4,4'-DDT and its metabolites have been identified in samples SMC-SD1-01 and SMC-SD4-01. Arochlor 1254 contains PCB congener peaks which co-elute at similar retention times as 4,4'-DDT and its metabolites. To quantitate the concentration of 4,4'-DDT present, the peak height contributed by the PCB concentration was calculated by comparison. with standards and subtracted frorr, the total peak height of the 4,4 I-DDT peak.

GLOSSARY OF PEST/PCB DATA

PATA OUALIFIERS

0 0 Indicates that the compounds was analyzed for but not detected. The minimum detection limit for the sample (not the method detection limit) is reported with the U (e.g., lOU). J - Indicates an estimated value. This flag is used in cases where a target analyte is detected at a level less than the lower quantification level. If the limit of quantification is 10 ug/L and a concentration of 3 . ug/L is calculated, it is reported as 35. B - This flag is used when the analyte is found in the associated blank as well as in the sample. It indicates possible/probable blank Contamination. This flag is also used for a TIC as well as for a positively identified TCL compound. E - Indicates that the compound was detected beyond the calibration range and was subsequently analyzed at a dilution. I - Interference. ABBREVXATIONS 8s - Indicates blank spike in which reagent grade water is spiked with the CLP matrix spiking solutions and carried through all the steps in the method. Spike recoveries are reported. 880 - Indicates blank spike duplicate. ns - Indicates matrix spike. XSD - Indicates matrix spike duplicate.

DL 0 Indicates that recoveries were not obtained because the extract had to be diluted for analysis.

I The set of samples consisted of (1) water sample and (36) Soil samples collected on 10/30/90. The samples were analyzed according to criteria set forth in CLP SOW 7/87. The following is a sumary of the QC results accompanying these sarnple results and a description of any problems encountered during ' their analysis: 1. ICVs, CCVs, and LCSs stock standards were purchased from Inorganic Ventures Laboratory. i 2. All ICV and CCV values were within control limits. I 3. All ICB and CCB values were within control limits. f 4. All preparation blank values were within control limits. 5. All LCS results were within the 80-120% control limits. 1;ote : The USEPA has dropped control limits for antimony and silver due to documented difficulties in obtaining reliable results. WESTON A*,ilyticshas adopted the same policy. 6. All matrix spike recoveries were within the 759125% control limits with the exception of As, Pb, Se, Ag, T1, V, Hg and Sb. All corresponding samples were flagged with an "N1@ according to CLP protocol.

7. All duplicate analyses were within the 20% RPD control limit with the exception of Pb and Zn. All corresponding samples were flagged with a gt*tt according to CLP protocol.

8. As, Pb and Se sample results were calculated by the method of standard addition (MSA). All corresponding samples were flagged with an "S" according to CLP protocol.

I 9. Zeeran background corrects for non-spectral interference I I only to 1.5 - 2.0. Samples 029 and 030 were diluted two L times to bring them within the limits of Zeeman

I correction.

INORGANIC NARRATIVE The following is a summary of the quality control results and a description of any problems encountered during the analysis of this batch of samples:

1. All sample holding times as required by 40CFR136 were met for water samples.

2. All preparation blanks were analyzed below the required detection limits. 3. All laboratory control standards (blank spikes) are within the control limits of 80-120%.

4. All calibration verification checks are within the required control limits of 85-115%. Calibration verification is performed using independent standards.

5. Matrix spike recoveries are within the 75-125% guidance limits with the exception of fluoride.

6. All replicate results are within the 20% guidance limit.

7. The analytical methods applied by the laboratory, unless otherwise requested, for- all inorganic analyses are derived from the U5EPA Method for Chemical Analysis of Water and Wastes (USEPA 600/4-79-020), and Standard Methods for the Examination of Water and Wastewater 16 -ed. Methods for the analysis of solid samples are derived from Test Methods for Evaluatina Solid Waste (USEPA SW846).

'$ J GLOSSARY OF TERMS - INORGANIC REPORTS DATA OUALIFIERS U - Indicates that the parameter was not detected at or above the reported limit. The associated numerical value is the sample detection limit.

t- Indicates that the original sample result is greater than 4x the spike amour,t added. The USEPA-CLP has determined that spike results on samples where this occurs may be unreliable and therefore, the control limits are not applicable. ABBREVIATIONS

NOTES

The laboratory is preparing a matrix spike at one per 20 frequency for TCLP samples of similar matrix. The Federal Register suggest that all matrix spikes be greater than 50%. A matrix duplicate is also prepared. The USEPA-CLP has dropped control limits for silver and antimony due to documented difficulties in obtaining reliable results. WESTON Analytics has adopted the same policy. Holding times for soil samples have not been promulgated by the - USEPA. For solid samples, all results are reported on a dry weight basis. ROY F.

The laboratory prepares a matrix spike at one per 20 frequency for TCLP samples. The Federal Register recommends that all matrix spikes be prepared at greater than 50% of the indigenous analyte concentration. A matrix duplicate is also prepared. The USEPA-CLP has dropped control limits for silver and antimony due to documented difficulties in obtaining reliable results. WESTOtJ Analytics, however, monitors it's recoveries for unusal occurrences of silver and/or antimony quantitication. Hslding times for soil samples have not been promulgated by the USEPA.

The samples were analyzed according to criteria set forth in CLP SOW 2/88 (Rev. 5.89) for TCL Volatile target compounds on 11-07,08-90. The following is a summary of the QC results accompanying these sample results and a description of any prcblems encountered during their analysis:

1. Non-target compounds were not detected in these samples.

2. All surrogate recoveries were within EPA QC limits.

3. All water matrix spike recoveries were within EPA QC limits. Soil matrix spike and spike duplicate samples are associated with RFW lot 9010L363.

4. The laboratory blanks contained the cornnon contaminant methylene chloride and acetone at levels less than 4x the CRQL. 5. Internal standard area were outside control limits for sample SMC-SD3-01. This sample was re-analyzed on 11-07-90 and similar results were obtained. Re-analysis results are available upon request.

6. All samples and method blanks analyzed on Instrument 5100 B contained a system contaminant which appeared to be acetic acid. This peak has been labeled on the chromatogram. /2- 17-f Jack R. Tuschall, Ph.D. Date Laboratory Manager Lionville Analytical Laboratory su

The samples were analyzed according to criteria set forth in CLP SOW 2/88 (rev. 5/89) for TCL Volatile target compounds on 12-13-90.

The following is a summary of the QC results accompanying these sample results and a description of any problems encountered during their analysis:

1. Non-target compounds were detected in these samples. 2. All surrogate recoveries were within EPA QC limits. 3. All matrix spike recoveries were within EPA QC limits.

4. The laboratory blank contained the common contaminants methylene chloride and acetone at I levels less than 4x the CRQL and the target compound carbon disulfide at a level less than the CRQL. 5. All internal standard area and retention time criteria were met.

The samples were extracted on 11-05,06-90 and analyzed according to criteria set forth in CLP SOW 02/88 (Rev. 05/89) for TCL Semivolatile target compounds on 11-20,21-90. The following is a summary of the QC results accompanying these sample results and a description of any problems encountered during their analysis: 1. Non-target compounds were detected in these samples.

5. The laboratory blank 90LE1253-KBl contained I the common contaminant di-n-butylphthalate at a level less than the CRQL. 6. Internal standard areas are outside the control limits for samples SMC-SD1-01, SMC- SD4-01, SMC-RA-34-01 UPP, and SMC-RA-34-01-UPP MSD. The matrix spike analysis of sample SMC- RA-34-01-UPP fulfilled the associated re- analysis requirements. The remaining samples were re-analyzed on 11-21-90 and similar results were obtained. =-analysis results are available upon request.

CLIENT: TRC/SHIELDALZX)Y SAMPLES RECEIVED: 10-31-90 RFX #: 9011L400, PEST/PCB W.O. I: 2724-05-01 BARRATIVE The set of samples consisted of one (1) soil sample, one (2) sediment samples, and three (3) water samples coll ccted on 10-31-90. Thc samples were extracted on 11-06-90 and analyzed according to criteria set forth in the Contract Laboratory Przqram for TCLP Pesticide and PCB target compounds on 12-06,07-90. Thc following is a sunrnary of the QC results accompe::;ting these sample results and a description of any prc8:lems en-ountered during their analysis: 1. Linearity and breakdown criteria were met on the primary column. Breakdown criteria for 4,4'-DDT were exceeded on 12-07-90 at 21:ZO. Katrix spike extracts of sample SMC-RA34-01- UPP were analyzed after this evaluation standard. It appears there was no impact on the spike recoveries.

2. Continuing calibration criteria were met for all conpounds on at least one column for all standards. 3. Retention time criteria were met for all compounds on both the primary and confirmation colunns.

4. All obtainable surrogate recoveries were within EPA QC lirnits. 5. All blank spike recoveries were within EPA QC limits.

6. The Pesticide Spiking Solution was inadvertently prepared at lox the usual concentration of pesticides. The blank spikes required a 10-fold dilution to maintain the pesticide concentrations within the linear range of the instrumeny. -2 - 7. All matrix spike recoveries were within EPA QC 1 imits. 8. Several soil and sediment samples appeared to contain mixtures of PCB compounds. PCB peaks characteristic of arochlors 1242, 1248, 1254, and 1260 were detected. Weathering and microbial degradation of soil and sediments can affect the relative ratio of congener peak size. Samples were identified and quantitated as the arochlors that produced the best fit compared with standards. 9. Both arochlor 1254 and 4,4'-DDT and its metabolites have been identified in samples SNC-SD1-01 and SMC-SD4-01. Arochlor 1254 contains PCB congener peaks which co-elute at sinilar retention times as 4,4'-DDT and its metabolites. To quantitate the concentration of 4,4'-DDT present, the peak height . contributed by the PCB concentration was calculated by conparison. with standards and subtracted fron; the total peak height of the 4 ,4 -DDT peak.

The set of samples consisted of four (4) water samples collected on 12-04-90.

The samples were extracted on 12-06-90 and analyzed according to criteria set forth in the Contract Laboratory Program for Pesticide and PCB target corpounds on 01-13,14-91.

The following is a summary of the QC results accompanying these sarple results and a description of any problems encountered during their analysis:

1. Linearity and breakdown criteria were met on the primary column.

2. For continuing calibration standards analyzed prior to the sanple extracts, the 15%criteria c,aIihration factor was exceeded for endrin on the SP2250/2401 co1ur.n on 01-13-91 at 11:53. The response for endrin resulted in an increase in sensitivity so the ability to ider-,tiflr this para7,;eter was not impaired.

3. KGtention time criteria were met for all carpounds in standards analyzed prior to the sar,ple extracts on the primary and confirrLation columns.

4. One (1) of seven (7) surrogate recoveries was below the EFA QC limits. The DBC surrogate recovery for sample SMC-SW09-01-ON (7%) was below the EPA QC limit of 24%.

5. All blank .spike reccveries were within EPA QC 1imits.

6. Samples 90LE1432-F:El RS and BSD required 10- fold dilutions to obtain spike recoveries b,rithin the linear range of the instrument.

The following is a summary of the quality control results and a description of any problems encountered during the analysis of this batch of samples:

1. All sample holding times as required by 40CFR136 were met for water samples.

2. All preparation blanks were analyzed below the required detection limits.

3. All laboratory control standards (blank spikes) are within the control limits of 80-120%.

4. kll calibration verification checks are within the required control limits of 85-115%. Calibration verification is performed. using independent standards.

5. Matrix spike recoveries are within the 75-125% guidance limits with the exception of fluoride.

6. All replicate results are within the 20% guidance limit.

7. The analytical methods applied by the laboratory, unless otherwise requested, for. all inorganic analyses are derived from the USEPA Method for Chemical P.i.alvsis of Water and Wastes (USEPA 600/4-79-020), and Standard Methods for the Examination of Water and Wastewater 16 ed. Methods for the analysis of solid samples are derived from Test Methods for Evaluatinq Solid Waste (USEPA SW846).

C - Indicates that the parameter was not detected at or above the reported limit. The associated numerical value is the sarr,ple detection limit. *- Indicates that the original sample result is greater than 4x the spike anount added. The USEPA-CLP has determined that spike results on samples where this occurs may be unreliable and therefore, the control limits are not applicable.

ABBREVIATIONS

The laboratory is preparing a matrix spike at one per 20 frequency ' for TCLP samples of similar matrix. The Federal Register suggest that all matrix spikes be greater than 50%. A matrix duplicate is also prepared. The USEPA-CLP has dropped control limits for silver and antimony due to documented difficulties in obtaining reliable results. WESTON Analytics has adopted the same policy. Holding t,imes for soil samples have not been promulgated by the - USEFA.. Fcr solid samples, all results are reported on a dry weight basis. 3 ROY F. hTSTON ItJC.

NARRATIVE The set of samples consisted of eight (8) water samples, six (6) soil samples and one (1) sediment sample collected on 10-31-90. The samples were analyzed according to criteria set forth in CLP SOW 2/88 (Rev. 5.89) for TCL Volatile target compounds on 11-07,08-90.

The following is a summary of the QC results accompanying these sample results and a description of any problems encountered during their analysis:

1. Non-target compounds were not detected in these samples.

2. All surrogate recoveries were within EPA QC limits.

3. All water matrix spike recoveries were within EPA QC limits. Soil matrix spike and spike duplicate samples are associated with RFW lot 9010L363.

4. The laboratory blanks contained the common contaminant methylene chloride and acetone at levels less than 4x the CRQL.

5. Internal standard area were outside control limits for sample SMC-SD3-01. This sample was re-analyzed on 11-07-90 and similar results were obtained. Re-analysis results are available upon request.

6. All samples and method blanks analyzed on Instrument 5100 B contained a system contaminant which appeared to be acetic acid. This peak has been labeled on the chromatogram. / I I/ 7dLk 1.4-1 12- 17-f * Jack R.

The set of samples consisted of three (3) water samples, one (1) soil sample, and two (2) sediment samples collected on 10-31-90. The samples were extracted on 11-05,06-90 and analyzed according to criteria set forth in CLP SOW 02/88 (Rev. 05/89) for TCL i Semivolatile target compounds on 11-20,21-90. The following is a summary of the QC results accompanying these sample results and a description of any problems encountered ! during their analysis: 1. Non-target compounds were detected in these I samples. 2. One (1) of seventy-eight (78) surrogate recoveries was outside EPA QC. However, EPA I CLP surrogate recovery criteria were met (i.e., no more than one outlier per fraction {acid and base neutral} and no recoveries less I than 10%). 3. Three (3) of twenty-two (22) water blank spike recoveries were outside EPA QC limits. All I soil blank spike recoveries were within EPA QC limits. I 4. Two (2) of twenty-two (22) soil matrix spike recoveries were outside EPA QC limits.

5. The laboratory blank 90LE1253-MB1 contained I the common contaminant di-n-butylphthalate at a level less than the CRQL. I 6. Internal standard areas are outside the control limits for samples SMC-SD1-01, SMC- SD4-01, SMC-RA-34-01 UPP, and SMC-RA-34-01-UPP MSD. The matrix spike analysis of sample SMC- I RA-34-01-UPP fulfilled the associated re- analysis requirements. The remaining samples were re-analyzed on 11-21-90 and similar I results were obtained. RE-analysis results are available upon request. f 3 +%a!-’/ -9 i Laboratory Manager 1 Lionville Analytical Laboratory OF BNA DAm 18

CLIENT: TRC/SHIELDALLOY SAMPLES RECEIVED: 10-21-90 RFX #: 9011L400, PEST/PCB W.0. #: 2724-05-01 NARRATIVE The set of samples consisted of one (1) soil sample, one (2) sediment samples, and three (3) water samples collL-.-.eted on 10-31-90. The samples were extracted on 11-06-90 and analyzed accc.:-Aing to criteria set forth in the Contract Laboratory Przgram fci- TCLP Pesticide and PCB target compounds on 12-06,07-30. Thc following is a summary of the QC results accompz.:;7ing these sample results and a description of any prc,:lerrs en2suntered during their analysis: 1. Linearity and breakdown criteria were met on the primary column. Breakdown criteria for 4,4'-DDT were exceeded on 12-07-90 at 21:20. Natrix spike extracts of sample SMC-RA34-01- UPP were analyzed after this evaluation standard. It appears there was no impact on the spike recoveries.

4. All obtainable surrogate recoveries were within EPA QC linits. 5. All blank spike recoveries were within EPA QC limits.

8. Several soil and sediment samples appeared to contain mixtures of PCB compounds. PCB peaks characteristic of arochlors 1242, 1248, 1254, and 1260 were detected. Weathering and microbial degradation of soil and sediments can affect the relative ratio of congener peak size. Samples were identified and quantitated as the arochlors that produced the best fit compared with standards. 9. Both arochlor 1254 and 4,4'-DDT and its metabolites have been identified in samples SMC-SD1-01 and SMC-SD4-01. Arochl or 1254 contains PCB congener peaks which co-elute at similar retention times as 4,4'-DDT and its metabolites. To quantitate the concentration of 4,4'-DDT present, the peak height e contributed by the PCB concentration was calculated by comparison with standards and subtracted from the total peak height of the 4,4'-DDT peak.

J - Indicates an estimated value. This flag is used in cases where a target analyte is detected at a level less than the lower quantification level. If the limit of quantification is 10 ug/L and a concentration of 3 ug/L is calculated, it is reported as 35. B - This flag is used when the analyte is found in the associated blank as well as in the sample. It indicates possible/probable blank contamination. This flag is also used for a TIC as well as for a positively identified TCL compound. E - Indicates that the compound was detected beyond the calibration range and was subsequently analyzed at a dilution. I - Interference. ABBREVIATIONS BS - Indicates blank spike in which reagent grade water is spiked with the CLP matrix spiking solutions and carried through all the steps in the method. Spike recoveries are reported.

The associated numerical value is the sample detection limit. *- Indicates that the original sample result is greater than 4x the spike amount added. The USEPA-CLP has determined that spike results on samples where this occurs may be unreliable and therefore, the control limits are not applicable. a ABBREVIATIONS 1.7 B - Method or preparation blank. MS - Matrix Spike. MSD - Matrix Spike Duplicate. REP - Sample Replicate. LC - Indicates a method LCS or Blank Spike. 1:c - Not calculable, result below the detection I limit.

The laboratory is preparing a matrix spike at one per 20 frequency for TCLP samples of similar matrix. The Federal Register suggest I that all matrix spikes be greater than 50%. A matrix duplicate is also prepared. The USEPA-CLP has dropped control limits for silver and antimony due to documented difficulties in obtaining reliable results. WESTON Analytics has adopted the same policy. Holding times for soil samples have not been promulgated by the - USEPA. For solid samples, all results are reported on a dry weight basis. ROY F.

The set of samples consisted of one (1) water sample and eight (8) soil samples collected on 10-30-90. The samples were extracted on 11-05,09-90 and analyzed according to criteria set forth in CLP SOW 02/88 (Rev. 05/89) for TCL Semivolatile target compounds on 11-20,26-90. The follok.ing is a summary of the QC results accompanying these sample results and a description of any problems encountered during their analysis:

1. Non-target compounds were detected in these samples.

2. All surrogate recoveries were within EPA QC limits.

3. Three (3) of twenty-two (22) water blank spike recoveries and one (1) of eleven (11) soil blank spike recoveries were outside EPA QC limits.

4. Two (2) of txenty-two (22) rrtatrix spike recoveries b'ere outside EPA QC limits. 9 5. The laboratory blanks contained the cJcnmon contaminants di-n-butylphthalate and bis(2- ethylhexyl)phthalate at levels less than the CRQL.

6. Internal standard area and retention time criteria were met for all samples and blanks.

The set of samples consisted of eight (8) soil samples and one (1) water sample collected on 10-30-90.

The samples were ' extracted on 11-06,09-90 and analyzed according to criteria set forth in the Contract Laboratory Program for Pesticide and PCB target compounds on 12-06,07-90.

The following is a summary of the QC results accompanying these sample results and a description of a.ny problems encountered during their analysis:

2. Continuing calibration criteria were met for all compounds on at least one column for standards analyzed prior to the sample extracts.

3. Retention tine crite.ia were net for all cornpounds on both the prinary& and confirnation columns.

4. One (1) of sixteen (16) surrogate' recoveries was outside EPA QC limits. The surrogate recovery for 90LE1274-MBl BS (159%) exceeded the EPA QC limit of 150%.

5. The Pesti c ide Spiking Solution was inadvertently prepared at lox the usual concentrations of pesticides. The blank and matrix spike required a ten-fold dilution to maintain the pesticide concentrations within the linear range of the instrument. a -2-

7. Tvo (2) of twelve (12) matrix spike recoveries were outside EPA QC limits.

DATA QUALIFIERS

U - Indicates that the compounds was analyzed for but not detected. The minimum detection limit for the sample (not the method detection limit) is reported with the U (e.g., 1OU).

J - Indicates an estimated value. This flag is used in cases where a target analyte is detected at a level

‘less than the lower quantification level. If the limit a of quantification is 10 ug/L and a concentration of 3 ug/L is calculated, it is reported as 3J.

B - This flag is used when the analyte is found in the associated blank as well as in the sample. It indicates possible/probable blank contamination. This flag is also used for a TIC as well as for a positively identified TCL compound.

E - Indicates that the compound was detected beyond the calibration range and was subsequently analyzed at a dilution.

I - Interference. ABBREVIATIONS

BS - Indicates blank spike in which reagent grade water is spiked with the CLP matrix spiking solutions and carried through all the steps in the method. Spike recoveries are reported.

BSD - Indicates blank spike duplicate.

MS - Indicates matrix spike. MSD - Indicates matrix spike duplicate. DL - Indicates that recoveries were not obtained because the extract had to be diluted for analysis.

NA - Not applicable.

4. All preparation blank values were within control limits.

5. All LCS results were within the 80-120% control limits. i 1:ote: The USEPA has dropped control limits for antimony and silver due to documented dif ficultie& in obtaining reliable results. WESTON A:,ilytics has adopted the same policy. J 6. All matrix spike recoveries were within the 750125% control limits with the exception of As, Pb, Se, Ag, T1, VI Hg and Sb. All corresponding samples were flagged with an (INf1 according to CLP protocol. I 7. All duplicate analyses were within the 20% RPD control limit with the exception of Pb and Zn. All corresponding samples were flagged with a according to CLP protocol. a. As, Pb and Se sample results were calculated by the method of standard addition (MSA). All corresponding sacples were flagged with an @lSvtaccording to CLP protocol.
