FIELD PROCEDURES . Page 1 Excavation Sampling Soil samples were collected using clean, two-inch diameter, six-inch long brass tubes driven into soil exposed in the excavation and/or obtained from each sample location with an excavator bucket using a rubber mallet The tubes were sealed with poiytetrafluoroethylene(PTFE)-coated sheets, plastic caps and duct tape to reduce volatile hydrocarbon loss, placed in an ice chest containing "blue ice," and submitted under chain-of-custody to a California-certified laboratory Selected samples were analyzed for Total Petroleum Hydrocarbons (TPH) using Modified EPA method 8015/Purge-and-Trap, and for Benzene, Toluene, Ethylbenzene, and Total Xylenes (BTEX), using EPA method 8020/Purge-and-Trap Stockpile Sampling Stockpile soil samples were collected by excavating one to three feet below the stockpile surface and driving two-inch diameter, six-inch long brass tubes into the soil The tubes were sealed with polytetrafluoroethylene (PTFE)-coated sheets, plastic caps and duct tape to reduce volatile hydrocarbon loss Four samples were collected from every 50 cubic yards of stockpiled soil and composited into one sample in the laboratory All samples were placed in an ice chest containing "blue ice," and submitted under chain-of=custody to a California-certified laboratory Samples were analyzed for Total Petroleum Hydrocarbons (TPH) using Modified EPA method 8015/Purge-and-Trap and for Benzene, Toluene, Ethylbenzene, and Total Xylenes (BTEX), using EPA method 8020/Purge-and-Trap Additional analysis included Volatile Organic Priority Pollutants (EPA method 624/8240), Cam 17 metals and 96 hour fish biassay Soil Borings The soil borings were drilled with a truck-mounted Mobile B-53 drill rig equipped with hollow-stem augers provided by Westex Drilling Soil samples were collected from the borings at five-foot maximum intervals with a modified California sampler equipped with clean, two-inch diameter, six-inch long brass tubes Samples tubes were sealed with polytetrafluoro ethylene (PTFE)-coated sheets, polyethylene caps and duct tape to reduce volatile hydrocarbon loss The samples were screened in the field with an organic vapor analyzer (OVA) to evaluate potential hydrocarbon content Selected samples were placed in an ice chest containing "blue ice," and submitted under chain-of-custody to a California-certified laboratory for analysis of Total Petroleum Hydrocarbons(TPH)using Modified EPA method 8015/Purge- and-Trap and for Benzene, Toluene, Ethylbenzene, and Total Xylenes (BTEX), using EPA method 8020/Purge-and-Trap `�W WALLACE-RUHL RecycW paper &ASS"IATE5 INC
