10 Introduction

The EPA Region I Office of Environmental Measurement and Evaluation at the request of Edward Hathaway Remedial Project Manager (RPM) for the Eastern Surplus Company Superfund Site in Meddybemps Maine performed an ambient air sampling study for volatile organic compounds (VOCS) at the site on October 29 1997 This study focused on collecting ambient air samples adjacent to the excavation area and along the perimeter of the site Samples were collected over a four-hour period to determine what VOCs are being emitted migrating off-site and impacting the community during soil intrusive activities at a hot spot area located in Quadrant II

The Eastern Surplus Company covers approximately four to five acres near the center of Meddybemps Maine Eastern Surplus Company is bordered by Meddybemps Lake to the north the Dennys River to the east Route 191 to the south and Stone Road to the west (see Figure 1) The site is heavily vegetated with many large trees and a substantial growth of young trees This property was originally inspected in October 1985 by ME DEP During the inspection ME DEP personnel noted chemical odors leaking electrical transformers hundreds of deteriorating drums and containers compressed gas cylinders 16000 pounds of calcium carbide and numerous areas of stained soil ME DEP immediately initiated emergency cleanup and removal measures and erected a fence to secure the property

Source sampling arranged by EPA and ME DEP between November 1985 and August 1990 identified more than fifty different hazardous materials on the property including PCBs chlorinated organic compounds heavy metals acids paints oils asbestos and pesticides Soil groundwater and sediment samples collected by EPA between 1987 and 1988 have shown that many of these contaminants were released into the environment During 1996 and 1997 the following media were sampled residential groundwater site groundwater site soils ambient air soil gas lake and river surface water and sediments fish were also collected

Soil samples from the hot spot area located in Quadrant II identified the following volatile organic compounds trichloroethene tetrachloroethene toluene ethylbenzene xylene methylene chloride acetone chloroform 12shydichloroethene 4-methyl-2-pentanone (methylisobutylketone) and methylethylketone(2-butanone)

31 Description

EPA Region I Standard Operating Procedure for the Sampling of Trace Volatile Organic Compounds using SUMMA Polished Stainless Steel Canisters EPA-REGl-ESDCAN-SAM-SOP March 1994 Revision 1 was used as the procedure to collect the ambient air samples Sub-atmospheric samples were collected in evacuated 6 liter canisters using the procedure described in Part 2 of the Region SOP described above Detailed descriptions of the quality assurance procedures are provided in Part 4

Canister samples were brought back to the EPA laboratory and analyzed starting on November 5 using a gas chromatographionshytrap mass spectrometer (GCMS) following the EPA Region I standard operating procedure entitled The Determination of Volatile Organic Compounds in Ambient Air using Summa Passivated Canisters a modification of EPA Method T014 - The Determination of Volatile Organic Compounds in Ambient Air using SUMMA Passivated Canister Sampling and Gas Chromatographic Analysis from the Compendium of Methods for the Determination of Toxic Organic Compounds in Ambient Air EPA-6004-84-041 May 1987 This analytical procedure was used to identify and quantify the VOCs listed on Table 1

32 Canister Cleaning and Leak Certification Procedures

321 Canister Cleaning Procedure

Prior to the sampling event on September 3 and 4 the canisters were cleaned by placing them in ovens maintained at 150degC evacuated to at least 10^ Torr and then pressurized with humidified nitrogen to approximately 3 0 psig This process was repeated three times Detailed descriptions of these procedures are provided in the document entitled Canister Cleaning Standard Operating Procedures EPA-REGl-OEMECANISTER-CLEANINGshySOP May 1996

322 Canister Leak Certification Procedure

At the end of the cleaning process described above the canisters were evacuated to less than 10^ Torr with a Pirani sensor the vacuum in each canister was measured The canisters were then placed on a shelf for at least 24 hours At the conclusion of this period the Pirani sensor was used again to measure the final canister vacuum which was then compared to the initial reading to determine if the canisters show signs of leaking All the canisters were certified on September 4 and 5 1997 Detailed descriptions of these procedures are provided in the document entitled Canister Leak Certification Standard Operating Procedures EPA-REGl-OEME CANISTER-LEAK-CERT-SOP May 1996

323 Canister Cleanliness Certification Procedure

After all the canisters were certified leak free each canister was pressurized with 25 humidified nitrogen and analyzed for contamination using GCFID All the canisters met clean certification analysis criteria of less than 10 ppbc TNMOC and less than 1 ppbc of any target compound The canisters were certified clean on September 16 1997 and recertified on October 24 1997 Detailed descriptions of these procedures are provided in the document entitled Pressurized Canisters for Clean Certification Standard Operating Procedures EPA-REGl-OEME CANISTER-PREP-SOP May 1996

33 Canister Analysis Ouality ControlOuality Assurance

331 Laboratory Blank

Humidified nitrogen was introduced into the analytical instrument inlet line prior to and after analyzing the canisters to serve as laboratory blanks The two laboratory blanks were analyzed to determine the background contamination present in the analytical instrumentation If the canister samples detect compounds below three times the blank value they were qualified as estimated values with a B If a compound concentration was not qualified the value was not subtracted from the sample value

The blank results are presented in Appendix B Benzene and toluene were detected above the reporting limit However the compounds which were qualified as estimated values with a B for several samples are as follows methylene chloride 112shytrichloro-122-trifluoroethane benzene toluene ethylbenzene and mp-xylene

332 FieldTrip Blank

Canister 1577 went through the procedures described in Section 32 and accompany the sampling canisters to the field and back to the laboratory to serve as a fieldtrip blank The canister was pressurized by the laboratory along with the other samples prior to analysis The fieldtrip blank canister was analyzed to determine if any cross contamination had occurred after the cleaningcertification process and before analysis If the canister samples detect compounds below three times the blank value they were qualified as estimated values with a B If a compound concentration was not qualified the blank value was not subtracted from the sample value

The results are presented in Appendix B There were no compounds detected above their reporting limit Therefore no compounds were qualified based on the fieldtrip blank

333 Data ReproducibilityPrecision Procedures

Canister 1560 was analyzed a second time for assessing analytical precision Two 05 liter aliquots were withdrawn from the canister and analyzed in a similar manner Those compounds having values above their reporting limits are presented in Table 2 The reporting limits for the nonpolar compounds are 016 ppbvv and 16 and 81 ppbvv for the polar compounds The percent differences were calculated and all fell within plusmn25 except for carbon tetrachloride and o-xylene However these compounds were not detected above 10 times their reporting limit therefore the data was not qualified

In addition two canister samples (Canister 1576 and Canister 1560) were collected simultaneously in parallel from sampling Station 1 to determine sampling precision The results are presented on Table 3 The percent difference between parallelduplicate sampling results was calculated All the compounds detected above their reporting limit agreed within plusmn25 except for chloromethane and 111-trichloroethene However these compounds were not detected above 10 times their reporting limit therefore the data was not qualified

334 Data Accuracy Procedures

A quality control canister sample (AAL-21380) containing selected VOCs was analyzed twice (QC-1 and QC-2) with the canister samples to determine analytical accuracy The results of the observed concentrations compared to the known acceptable range are reported on Table 4 The observed concentrations all fell within the acceptable range (80 - 120 of the acceptable value) except methylene chloride carbon tetrachloride and 12shydichloropropane in QC-1 and 12-dichloroethane in QC-2 The compounds which fell outside of the acceptable range in QC-1 and QC-2 were acceptable in QC-2 and QC-1 respectively Therefore no compound was qualified

335 Canister Surrogate Spiking Procedure

Prior to analysis surrogate compounds 12-dichloroethane d4 toluene d8 and p-bromofluorobenzene were added to the analytical system prior to analyzing each sample The results are presented in Appendix A on the second page of the analytical report All surrogate compound recoveries were within the acceptable range of 60 - 140

40 Meteorological Measurement Method

33 Canister Analysis Ouality ControlOuality Assurance

331 Laboratory Blank

Humidified nitrogen was introduced into the analytical instrument inlet line prior to and after analyzing the canisters to serve as laboratory blanks The two laboratory blanks were analyzed to determine the background contamination present in the analytical instrumentation If the canister samples detect compounds below three times the blank value they were qualified as estimated values with a B If a compound concentration was not qualified the value was not subtracted from the sample value

The blank results are presented in Appendix B Benzene and toluene were detected above the reporting limit However the compounds which were qualified as estimated values with a B for several samples are as follows methylene chloride 112shytrichloro-122-trifluoroethane benzene toluene ethylbenzene and mp-xylene

332 FieldTrip Blank

Canister 1577 went through the procedures described in Section 32 and accompany the sampling canisters to the field and back to the laboratory to serve as a fieldtrip blank The canister was pressurized by the laboratory along with the other samples prior to analysis The fieldtrip blank canister was analyzed to determine if any cross contamination had occurred after the cleaningcertification process and before analysis If the canister samples detect compounds below three times the blank value they were qualified as estimated values with a B If a compound concentration was not qualified the blank value was not subtracted from the sample value

The results are presented in Appendix B There were no compounds detected above their reporting limit Therefore no compounds were qualified based on the fieldtrip blank

333 Data ReproducibilityPrecision Procedures

Canister 1560 was analyzed a second time for assessing analytical precision Two 05 liter aliquots were withdrawn from the canister and analyzed in a similar manner Those compounds having values above their reporting limits are presented in Table 2 The reporting limits for the nonpolar compounds are 016 ppbvv and 16 and 81 ppbvv for the polar compounds The percent differences were calculated and all fell within plusmn25 except for carbon tetrachloride and o-xylene However these compounds were not detected above 10 times their reporting limit therefore the data was not qualified

In addition two canister samples (Canister 1576 and Canister 1560) were collected simultaneously in parallel from sampling Station 1 to determine sampling precision The results are presented on Table 3 The percent difference between parallelduplicate sampling results was calculated All the compounds detected above their reporting limit agreed within plusmn25 except for chloromethane and 111-trichloroethene However these compounds were not detected above 10 times their reporting limit therefore the data was not qualified

334 Data Accuracy Procedures

A quality control canister sample (AAL-21380) containing selected VOCs was analyzed twice (QC-1 and QC-2) with the canister samples to determine analytical accuracy The results of the observed concentrations compared to the known acceptable range are reported on Table 4 The observed concentrations all fell within the acceptable range (80 - 120 of the acceptable value) except methylene chloride carbon tetrachloride and 12shydichloropropane in QC-1 and 12-dichloroethane in QC-2 The compounds which fell outside of the acceptable range in QC-1 and QC-2 were acceptable in QC-2 and QC-1 respectively Therefore no compound was qualified

335 Canister Surrogate Spiking Procedure

Prior to analysis surrogate compounds 12-dichloroethane d4 toluene d8 and p-bromofluorobenzene were added to the analytical system prior to analyzing each sample The results are presented in Appendix A on the second page of the analytical report All surrogate compound recoveries were within the acceptable range of 60 - 140

10 Introduction

The EPA Region I Office of Environmental Measurement and Evaluation at the request of Edward Hathaway Remedial Project Manager (RPM) for the Eastern Surplus Company Superfund Site in Meddybemps Maine performed an ambient air sampling study for volatile organic compounds (VOCS) at the site on October 29 1997 This study focused on collecting ambient air samples adjacent to the excavation area and along the perimeter of the site Samples were collected over a four-hour period to determine what VOCs are being emitted migrating off-site and impacting the community during soil intrusive activities at a hot spot area located in Quadrant II

The Eastern Surplus Company covers approximately four to five acres near the center of Meddybemps Maine Eastern Surplus Company is bordered by Meddybemps Lake to the north the Dennys River to the east Route 191 to the south and Stone Road to the west (see Figure 1) The site is heavily vegetated with many large trees and a substantial growth of young trees This property was originally inspected in October 1985 by ME DEP During the inspection ME DEP personnel noted chemical odors leaking electrical transformers hundreds of deteriorating drums and containers compressed gas cylinders 16000 pounds of calcium carbide and numerous areas of stained soil ME DEP immediately initiated emergency cleanup and removal measures and erected a fence to secure the property

Source sampling arranged by EPA and ME DEP between November 1985 and August 1990 identified more than fifty different hazardous materials on the property including PCBs chlorinated organic compounds heavy metals acids paints oils asbestos and pesticides Soil groundwater and sediment samples collected by EPA between 1987 and 1988 have shown that many of these contaminants were released into the environment During 1996 and 1997 the following media were sampled residential groundwater site groundwater site soils ambient air soil gas lake and river surface water and sediments fish were also collected

Soil samples from the hot spot area located in Quadrant II identified the following volatile organic compounds trichloroethene tetrachloroethene toluene ethylbenzene xylene methylene chloride acetone chloroform 12shydichloroethene 4-methyl-2-pentanone (methylisobutylketone) and methylethylketone(2-butanone)

30 Canister VOC Air Sampling and Analytical Methodology

31 Description

EPA Region I Standard Operating Procedure for the Sampling of Trace Volatile Organic Compounds using SUMMA Polished Stainless Steel Canisters EPA-REGl-ESDCAN-SAM-SOP March 1994 Revision 1 was used as the procedure to collect the ambient air samples Sub-atmospheric samples were collected in evacuated 6 liter canisters using the procedure described in Part 2 of the Region SOP described above Detailed descriptions of the quality assurance procedures are provided in Part 4

Canister samples were brought back to the EPA laboratory and analyzed starting on November 5 using a gas chromatographionshytrap mass spectrometer (GCMS) following the EPA Region I standard operating procedure entitled The Determination of Volatile Organic Compounds in Ambient Air using Summa Passivated Canisters a modification of EPA Method T014 - The Determination of Volatile Organic Compounds in Ambient Air using SUMMA Passivated Canister Sampling and Gas Chromatographic Analysis from the Compendium of Methods for the Determination of Toxic Organic Compounds in Ambient Air EPA-6004-84-041 May 1987 This analytical procedure was used to identify and quantify the VOCs listed on Table 1

32 Canister Cleaning and Leak Certification Procedures

321 Canister Cleaning Procedure

Prior to the sampling event on September 3 and 4 the canisters were cleaned by placing them in ovens maintained at 150degC evacuated to at least 10^ Torr and then pressurized with humidified nitrogen to approximately 3 0 psig This process was repeated three times Detailed descriptions of these procedures are provided in the document entitled Canister Cleaning Standard Operating Procedures EPA-REGl-OEMECANISTER-CLEANINGshySOP May 1996

322 Canister Leak Certification Procedure

At the end of the cleaning process described above the canisters were evacuated to less than 10^ Torr with a Pirani sensor the vacuum in each canister was measured The canisters were then placed on a shelf for at least 24 hours At the conclusion of this period the Pirani sensor was used again to measure the final canister vacuum which was then compared to the initial reading to determine if the canisters show signs of leaking All the canisters were certified on September 4 and 5 1997 Detailed descriptions of these procedures are provided in the document entitled Canister Leak Certification Standard Operating Procedures EPA-REGl-OEME CANISTER-LEAK-CERT-SOP May 1996

323 Canister Cleanliness Certification Procedure

After all the canisters were certified leak free each canister was pressurized with 25 humidified nitrogen and analyzed for contamination using GCFID All the canisters met clean certification analysis criteria of less than 10 ppbc TNMOC and less than 1 ppbc of any target compound The canisters were certified clean on September 16 1997 and recertified on October 24 1997 Detailed descriptions of these procedures are provided in the document entitled Pressurized Canisters for Clean Certification Standard Operating Procedures EPA-REGl-OEME CANISTER-PREP-SOP May 1996

Canisters were stored under pressure until October 24 1997 when they were re-evacuated to less than 10^ Torr Detailed descriptions of these procedures are provided in the document entitled Canister Evacuation Standard Operating Procedures EPA-REGl-OEMECAN-EVACUATION-SOP May 1996

33 Canister Analysis Ouality ControlOuality Assurance

331 Laboratory Blank

Humidified nitrogen was introduced into the analytical instrument inlet line prior to and after analyzing the canisters to serve as laboratory blanks The two laboratory blanks were analyzed to determine the background contamination present in the analytical instrumentation If the canister samples detect compounds below three times the blank value they were qualified as estimated values with a B If a compound concentration was not qualified the value was not subtracted from the sample value

The blank results are presented in Appendix B Benzene and toluene were detected above the reporting limit However the compounds which were qualified as estimated values with a B for several samples are as follows methylene chloride 112shytrichloro-122-trifluoroethane benzene toluene ethylbenzene and mp-xylene

332 FieldTrip Blank

Canister 1577 went through the procedures described in Section 32 and accompany the sampling canisters to the field and back to the laboratory to serve as a fieldtrip blank The canister was pressurized by the laboratory along with the other samples prior to analysis The fieldtrip blank canister was analyzed to determine if any cross contamination had occurred after the cleaningcertification process and before analysis If the canister samples detect compounds below three times the blank value they were qualified as estimated values with a B If a compound concentration was not qualified the blank value was not subtracted from the sample value

The results are presented in Appendix B There were no compounds detected above their reporting limit Therefore no compounds were qualified based on the fieldtrip blank

333 Data ReproducibilityPrecision Procedures

Canister 1560 was analyzed a second time for assessing analytical precision Two 05 liter aliquots were withdrawn from the canister and analyzed in a similar manner Those compounds having values above their reporting limits are presented in Table 2 The reporting limits for the nonpolar compounds are 016 ppbvv and 16 and 81 ppbvv for the polar compounds The percent differences were calculated and all fell within plusmn25 except for carbon tetrachloride and o-xylene However these compounds were not detected above 10 times their reporting limit therefore the data was not qualified

In addition two canister samples (Canister 1576 and Canister 1560) were collected simultaneously in parallel from sampling Station 1 to determine sampling precision The results are presented on Table 3 The percent difference between parallelduplicate sampling results was calculated All the compounds detected above their reporting limit agreed within plusmn25 except for chloromethane and 111-trichloroethene However these compounds were not detected above 10 times their reporting limit therefore the data was not qualified

334 Data Accuracy Procedures

A quality control canister sample (AAL-21380) containing selected VOCs was analyzed twice (QC-1 and QC-2) with the canister samples to determine analytical accuracy The results of the observed concentrations compared to the known acceptable range are reported on Table 4 The observed concentrations all fell within the acceptable range (80 - 120 of the acceptable value) except methylene chloride carbon tetrachloride and 12shydichloropropane in QC-1 and 12-dichloroethane in QC-2 The compounds which fell outside of the acceptable range in QC-1 and QC-2 were acceptable in QC-2 and QC-1 respectively Therefore no compound was qualified

335 Canister Surrogate Spiking Procedure

Prior to analysis surrogate compounds 12-dichloroethane d4 toluene d8 and p-bromofluorobenzene were added to the analytical system prior to analyzing each sample The results are presented in Appendix A on the second page of the analytical report All surrogate compound recoveries were within the acceptable range of 60 - 140

40 Meteorological Measurement Method

41 Description

A portable meteorological measuring system was located at sampling location 5 which was positioned in the open field across the road (route 191) from the site main entrance gate The system measured wind speed wind direction ambient temperature relative humidity and atmospheric pressure continuously over the duration of the sampling event to collect data that represented local meteorological conditions The meteorological station operating and data recording procedures in the manufacturers manual were followed The systems sensors were attached to a 15-foot high portable tripod

33 Canister Analysis Ouality ControlOuality Assurance

331 Laboratory Blank

Humidified nitrogen was introduced into the analytical instrument inlet line prior to and after analyzing the canisters to serve as laboratory blanks The two laboratory blanks were analyzed to determine the background contamination present in the analytical instrumentation If the canister samples detect compounds below three times the blank value they were qualified as estimated values with a B If a compound concentration was not qualified the value was not subtracted from the sample value

The blank results are presented in Appendix B Benzene and toluene were detected above the reporting limit However the compounds which were qualified as estimated values with a B for several samples are as follows methylene chloride 112shytrichloro-122-trifluoroethane benzene toluene ethylbenzene and mp-xylene

332 FieldTrip Blank

Canister 1577 went through the procedures described in Section 32 and accompany the sampling canisters to the field and back to the laboratory to serve as a fieldtrip blank The canister was pressurized by the laboratory along with the other samples prior to analysis The fieldtrip blank canister was analyzed to determine if any cross contamination had occurred after the cleaningcertification process and before analysis If the canister samples detect compounds below three times the blank value they were qualified as estimated values with a B If a compound concentration was not qualified the blank value was not subtracted from the sample value

The results are presented in Appendix B There were no compounds detected above their reporting limit Therefore no compounds were qualified based on the fieldtrip blank

333 Data ReproducibilityPrecision Procedures

Canister 1560 was analyzed a second time for assessing analytical precision Two 05 liter aliquots were withdrawn from the canister and analyzed in a similar manner Those compounds having values above their reporting limits are presented in Table 2 The reporting limits for the nonpolar compounds are 016 ppbvv and 16 and 81 ppbvv for the polar compounds The percent differences were calculated and all fell within plusmn25 except for carbon tetrachloride and o-xylene However these compounds were not detected above 10 times their reporting limit therefore the data was not qualified

In addition two canister samples (Canister 1576 and Canister 1560) were collected simultaneously in parallel from sampling Station 1 to determine sampling precision The results are presented on Table 3 The percent difference between parallelduplicate sampling results was calculated All the compounds detected above their reporting limit agreed within plusmn25 except for chloromethane and 111-trichloroethene However these compounds were not detected above 10 times their reporting limit therefore the data was not qualified

334 Data Accuracy Procedures

A quality control canister sample (AAL-21380) containing selected VOCs was analyzed twice (QC-1 and QC-2) with the canister samples to determine analytical accuracy The results of the observed concentrations compared to the known acceptable range are reported on Table 4 The observed concentrations all fell within the acceptable range (80 - 120 of the acceptable value) except methylene chloride carbon tetrachloride and 12shydichloropropane in QC-1 and 12-dichloroethane in QC-2 The compounds which fell outside of the acceptable range in QC-1 and QC-2 were acceptable in QC-2 and QC-1 respectively Therefore no compound was qualified

On October 29 1997 six ambient air samples were collected over a four-hour period from five sampling stations These stations were located adjacent to the hot spot area in Quadrant II on Mrs Orchards property near the concrete dam on the security fence gate along the western boundary along the northern site boundary and in the open field across route 191 The air samples were collected using certified cleaned evacuated fused silica lined 6 liter stainless steel canisters manufactured by Restek The canisters were analyzed for the volatile organic compounds (VOCs) listed on Table 1 using a gas chromatographionshytrap mass spectrometer (GCMS) Air sampling was conducted while the soils in the hot spot area were being excavated and stock piled to the side The cleared area will be used for the vapor extractionair sparging testing program to be carried out the week of November 10

12 Program Objective

The purpose of this survey was to collect ambient air samples for the volatile organic compounds listed on Table 1 to help determine the extent these compounds are being emitted from the hot spot area in Quadrant II migrating offsite and impacting the community during soil intrusive activities The data presented in this report will be used by the EPA and State of ME DEP to perform a human health risk assessment

20 Sampling Locations

The sampling network described below was used during the October 29 1997 study These stations were selected based on where homes are located relative to Quadrant II

Sampiina Station Ul

This station was located adjacent to the hot spot area in Quadrant II next to monitoring well MW-3B This location was chosen to collect data to be representative of the VOCs being emitted from the contaminated soils during excavation activities Two canisters (canister 1570 and 1560) were collected side-byshyside to serve as duplicate samples for obtaining precision data

Canister samples were brought back to the EPA laboratory and analyzed starting on November 5 using a gas chromatographionshytrap mass spectrometer (GCMS) following the EPA Region I standard operating procedure entitled The Determination of Volatile Organic Compounds in Ambient Air using Summa Passivated Canisters a modification of EPA Method T014 - The Determination of Volatile Organic Compounds in Ambient Air using SUMMA Passivated Canister Sampling and Gas Chromatographic Analysis from the Compendium of Methods for the Determination of Toxic Organic Compounds in Ambient Air EPA-6004-84-041 May 1987 This analytical procedure was used to identify and quantify the VOCs listed on Table 1

32 Canister Cleaning and Leak Certification Procedures

321 Canister Cleaning Procedure

Prior to the sampling event on September 3 and 4 the canisters were cleaned by placing them in ovens maintained at 150degC evacuated to at least 10^ Torr and then pressurized with humidified nitrogen to approximately 3 0 psig This process was repeated three times Detailed descriptions of these procedures are provided in the document entitled Canister Cleaning Standard Operating Procedures EPA-REGl-OEMECANISTER-CLEANINGshySOP May 1996

322 Canister Leak Certification Procedure

At the end of the cleaning process described above the canisters were evacuated to less than 10^ Torr with a Pirani sensor the vacuum in each canister was measured The canisters were then placed on a shelf for at least 24 hours At the conclusion of this period the Pirani sensor was used again to measure the final canister vacuum which was then compared to the initial reading to determine if the canisters show signs of leaking All the canisters were certified on September 4 and 5 1997 Detailed descriptions of these procedures are provided in the document entitled Canister Leak Certification Standard Operating Procedures EPA-REGl-OEME CANISTER-LEAK-CERT-SOP May 1996

323 Canister Cleanliness Certification Procedure

After all the canisters were certified leak free each canister was pressurized with 25 humidified nitrogen and analyzed for contamination using GCFID All the canisters met clean certification analysis criteria of less than 10 ppbc TNMOC and less than 1 ppbc of any target compound The canisters were certified clean on September 16 1997 and recertified on October 24 1997 Detailed descriptions of these procedures are provided in the document entitled Pressurized Canisters for Clean Certification Standard Operating Procedures EPA-REGl-OEME CANISTER-PREP-SOP May 1996

31 Description

EPA Region I Standard Operating Procedure for the Sampling of Trace Volatile Organic Compounds using SUMMA Polished Stainless Steel Canisters EPA-REGl-ESDCAN-SAM-SOP March 1994 Revision 1 was used as the procedure to collect the ambient air samples Sub-atmospheric samples were collected in evacuated 6 liter canisters using the procedure described in Part 2 of the Region SOP described above Detailed descriptions of the quality assurance procedures are provided in Part 4

Canister samples were brought back to the EPA laboratory and analyzed starting on November 5 using a gas chromatographionshytrap mass spectrometer (GCMS) following the EPA Region I standard operating procedure entitled The Determination of Volatile Organic Compounds in Ambient Air using Summa Passivated Canisters a modification of EPA Method T014 - The Determination of Volatile Organic Compounds in Ambient Air using SUMMA Passivated Canister Sampling and Gas Chromatographic Analysis from the Compendium of Methods for the Determination of Toxic Organic Compounds in Ambient Air EPA-6004-84-041 May 1987 This analytical procedure was used to identify and quantify the VOCs listed on Table 1

32 Canister Cleaning and Leak Certification Procedures

321 Canister Cleaning Procedure

Prior to the sampling event on September 3 and 4 the canisters were cleaned by placing them in ovens maintained at 150degC evacuated to at least 10^ Torr and then pressurized with humidified nitrogen to approximately 3 0 psig This process was repeated three times Detailed descriptions of these procedures are provided in the document entitled Canister Cleaning Standard Operating Procedures EPA-REGl-OEMECANISTER-CLEANINGshySOP May 1996

322 Canister Leak Certification Procedure

At the end of the cleaning process described above the canisters were evacuated to less than 10^ Torr with a Pirani sensor the vacuum in each canister was measured The canisters were then placed on a shelf for at least 24 hours At the conclusion of this period the Pirani sensor was used again to measure the final canister vacuum which was then compared to the initial reading to determine if the canisters show signs of leaking All the canisters were certified on September 4 and 5 1997 Detailed descriptions of these procedures are provided in the document entitled Canister Leak Certification Standard Operating Procedures EPA-REGl-OEME CANISTER-LEAK-CERT-SOP May 1996

323 Canister Cleanliness Certification Procedure

After all the canisters were certified leak free each canister was pressurized with 25 humidified nitrogen and analyzed for contamination using GCFID All the canisters met clean certification analysis criteria of less than 10 ppbc TNMOC and less than 1 ppbc of any target compound The canisters were certified clean on September 16 1997 and recertified on October 24 1997 Detailed descriptions of these procedures are provided in the document entitled Pressurized Canisters for Clean Certification Standard Operating Procedures EPA-REGl-OEME CANISTER-PREP-SOP May 1996

Canisters were stored under pressure until October 24 1997 when they were re-evacuated to less than 10^ Torr Detailed descriptions of these procedures are provided in the document entitled Canister Evacuation Standard Operating Procedures EPA-REGl-OEMECAN-EVACUATION-SOP May 1996

33 Canister Analysis Ouality ControlOuality Assurance

331 Laboratory Blank

Humidified nitrogen was introduced into the analytical instrument inlet line prior to and after analyzing the canisters to serve as laboratory blanks The two laboratory blanks were analyzed to determine the background contamination present in the analytical instrumentation If the canister samples detect compounds below three times the blank value they were qualified as estimated values with a B If a compound concentration was not qualified the value was not subtracted from the sample value

The blank results are presented in Appendix B Benzene and toluene were detected above the reporting limit However the compounds which were qualified as estimated values with a B for several samples are as follows methylene chloride 112shytrichloro-122-trifluoroethane benzene toluene ethylbenzene and mp-xylene

332 FieldTrip Blank

Canister 1577 went through the procedures described in Section 32 and accompany the sampling canisters to the field and back to the laboratory to serve as a fieldtrip blank The canister was pressurized by the laboratory along with the other samples prior to analysis The fieldtrip blank canister was analyzed to determine if any cross contamination had occurred after the cleaningcertification process and before analysis If the canister samples detect compounds below three times the blank value they were qualified as estimated values with a B If a compound concentration was not qualified the blank value was not subtracted from the sample value

The results are presented in Appendix B There were no compounds detected above their reporting limit Therefore no compounds were qualified based on the fieldtrip blank

333 Data ReproducibilityPrecision Procedures

Canister 1560 was analyzed a second time for assessing analytical precision Two 05 liter aliquots were withdrawn from the canister and analyzed in a similar manner Those compounds having values above their reporting limits are presented in Table 2 The reporting limits for the nonpolar compounds are 016 ppbvv and 16 and 81 ppbvv for the polar compounds The percent differences were calculated and all fell within plusmn25 except for carbon tetrachloride and o-xylene However these compounds were not detected above 10 times their reporting limit therefore the data was not qualified

In addition two canister samples (Canister 1576 and Canister 1560) were collected simultaneously in parallel from sampling Station 1 to determine sampling precision The results are presented on Table 3 The percent difference between parallelduplicate sampling results was calculated All the compounds detected above their reporting limit agreed within plusmn25 except for chloromethane and 111-trichloroethene However these compounds were not detected above 10 times their reporting limit therefore the data was not qualified

334 Data Accuracy Procedures

A quality control canister sample (AAL-21380) containing selected VOCs was analyzed twice (QC-1 and QC-2) with the canister samples to determine analytical accuracy The results of the observed concentrations compared to the known acceptable range are reported on Table 4 The observed concentrations all fell within the acceptable range (80 - 120 of the acceptable value) except methylene chloride carbon tetrachloride and 12shydichloropropane in QC-1 and 12-dichloroethane in QC-2 The compounds which fell outside of the acceptable range in QC-1 and QC-2 were acceptable in QC-2 and QC-1 respectively Therefore no compound was qualified

335 Canister Surrogate Spiking Procedure

Prior to analysis surrogate compounds 12-dichloroethane d4 toluene d8 and p-bromofluorobenzene were added to the analytical system prior to analyzing each sample The results are presented in Appendix A on the second page of the analytical report All surrogate compound recoveries were within the acceptable range of 60 - 140

332 FieldTrip Blank

Canister 1577 went through the procedures described in Section 32 and accompany the sampling canisters to the field and back to the laboratory to serve as a fieldtrip blank The canister was pressurized by the laboratory along with the other samples prior to analysis The fieldtrip blank canister was analyzed to determine if any cross contamination had occurred after the cleaningcertification process and before analysis If the canister samples detect compounds below three times the blank value they were qualified as estimated values with a B If a compound concentration was not qualified the blank value was not subtracted from the sample value

The results are presented in Appendix B There were no compounds detected above their reporting limit Therefore no compounds were qualified based on the fieldtrip blank

333 Data ReproducibilityPrecision Procedures

Canister 1560 was analyzed a second time for assessing analytical precision Two 05 liter aliquots were withdrawn from the canister and analyzed in a similar manner Those compounds having values above their reporting limits are presented in Table 2 The reporting limits for the nonpolar compounds are 016 ppbvv and 16 and 81 ppbvv for the polar compounds The percent differences were calculated and all fell within plusmn25 except for carbon tetrachloride and o-xylene However these compounds were not detected above 10 times their reporting limit therefore the data was not qualified

In addition two canister samples (Canister 1576 and Canister 1560) were collected simultaneously in parallel from sampling Station 1 to determine sampling precision The results are presented on Table 3 The percent difference between parallelduplicate sampling results was calculated All the compounds detected above their reporting limit agreed within plusmn25 except for chloromethane and 111-trichloroethene However these compounds were not detected above 10 times their reporting limit therefore the data was not qualified

334 Data Accuracy Procedures

A quality control canister sample (AAL-21380) containing selected VOCs was analyzed twice (QC-1 and QC-2) with the canister samples to determine analytical accuracy The results of the observed concentrations compared to the known acceptable range are reported on Table 4 The observed concentrations all fell within the acceptable range (80 - 120 of the acceptable value) except methylene chloride carbon tetrachloride and 12shydichloropropane in QC-1 and 12-dichloroethane in QC-2 The compounds which fell outside of the acceptable range in QC-1 and QC-2 were acceptable in QC-2 and QC-1 respectively Therefore no compound was qualified

335 Canister Surrogate Spiking Procedure

Prior to analysis surrogate compounds 12-dichloroethane d4 toluene d8 and p-bromofluorobenzene were added to the analytical system prior to analyzing each sample The results are presented in Appendix A on the second page of the analytical report All surrogate compound recoveries were within the acceptable range of 60 - 140

40 Meteorological Measurement Method

41 Description

A portable meteorological measuring system was located at sampling location 5 which was positioned in the open field across the road (route 191) from the site main entrance gate The system measured wind speed wind direction ambient temperature relative humidity and atmospheric pressure continuously over the duration of the sampling event to collect data that represented local meteorological conditions The meteorological station operating and data recording procedures in the manufacturers manual were followed The systems sensors were attached to a 15-foot high portable tripod

Components of the measuring system are described below

bull The data recording system consists of an Omnidata International Easy Logger Field Unit Easy logger Terminal and a 32K EPROM Data Storage Pack The Easy Logger Field Unit is housed in a 1496 X 1496 X 827 253 pound steel constructed FE Mental Field Enclosure

bull The atmospheric pressure sensor is a Weathertronics Model 7105shyA Barometer housed inside the enclosure described above

bull Relative humidity and temperature are measured with an ES-120 Vaisala Temperature and relative Humidity Probe housed inside an EA-13 0 RM Young Radiation Shield

bull Wind direction and horizontal wind speed are measured with an RM Young Wind Monitor - AQ Model 05305 The wind sensors will be oriented to magnetic north using a magnetic compass and checked for proper orientation prior to the sampling event

The October 29 1997 meteorological data are presented in Appendix C Between 0634 and 1219 the average ambient temperature was 428degC (40degF) ranging from -05degC to 665degC the average barometric pressure was 2975 inches of mercury ranging from 2977 to 2971 inches of mercury the average percent relative humidity was 75 ranging from 948 to 575 the average wind speed was 49 mph ranging from 29 to 91 mph the wind direction was from the west southwest 42 of the time and from the west northwest 58 of the time with the average being from the west (2 74 degrees) The reported wind direction data is relative to magnetic north

50 Air Sampling Results and Discussions

On October 29 1997 ambient air canister samples were collected adjacent to the hot spot area in Quadrant II and along the perimeter of the site over a four-hour period while soils were being excavated Sampling locations were positioned to characterize the VOCs volatilizing from the area being excavated and the extent they were migrating offsite The data collected during the study are presented in Appendix A and summarized on Table 5 The data reported on Table 5 are only the values which were detected above the reporting limits

bull14shy

The data collected from Station 1 which was located adjacent to the hot spot excavation area was determined to have the potential for the highest VOC concentrations At Station 1 methylene chloride was detected at 135 ugm^ toluene at 47 ugm^ tetrachloroethane at 58 ugm^ ethylbenzene at 20 ugm-^ mpshyxylene at 33 ugm^ and o-xylene at 15 ugm^ These levels were much higher than those detected at the other perimeter sampling locations which shows that these compounds did not migrate offsite and impact local residents

At Station 1 111-trichloroethane was detected at an average concentration of 4 ugm^ ranging from 04 ugm^ to 71 ugm^ and at Station 4 it was detected at 87 ugm^ Station 4 was positioned on the fence along the northern perimeter which according to the average wind direction during the sampling period was upwind of the excavation area It is possible that Station 4 was impacted from fugitive emissions from the site during clearing and excavation activities At the rest of the sampling stations 111-trichloroethane was detected at 03 ugm^ to 04 ugm^

The following compounds were detected at relatively the same concentrations at each of the sampling locations dichlorodishyfluoromethane (14 - 21 ugm^) chloromethane (05 - 09 ugm^) trichlorofluoromethane(10 - 12 ugm^) 112-trichloro-l22shytrifluoroethane (05 - 07 ugm^) benzene (03 - 04 ugm^) and carbon tetrachloride (03 - 04 ugm^)

The compound 26-bis(11-dimethyl)-phenol was tentatively identified in all the samples including the blanks Therefore the reported concentrations were qualified with a B The sample collected at station 1 also identified tetramethylshybenzene 1-methylcyclohexane and camphene at estimated concentrations of 2 ppbv 3 ppbv and 2 ppbv respectively

The data presented in this report are of acceptable quality to represent the levels of VOCs present at the sampling locations under the specific conditions prevailing during the sampling event These levels may vary given differing site activities and meteorological conditions
