Paq• 2 <br /> trench near the on-site building was discolored and <br /> malodorous- apparently as a result of fuel hydrocarbon <br /> contamination. Soil excavated from the trench near the <br /> western property boundary showed no evidence of <br /> contamination. All excavated soil was placed atop 6 mil <br /> polyethylene sheeting and covered with the sheeting. <br /> On August 24, 1994, the soil storage piles were sampled for <br /> certified laboratory analyses in accordance with PHS/EHD <br /> and Regional Water Quality Control Board guidelines . Each <br /> of the two discrete soil samples (one per every 20 cubic <br /> yards of contaminated soil ) was acquired by driving a 1 . 9 <br /> inch diameter by 6. 0 inch long clean brass tube into the <br /> soil until each tube was completely filled with <br /> consolidated material . Upon being withdrawn from the soil , <br /> the ends of each tube were covered with aluminum foil , <br /> fitted with plastic caps, and sealed with duct tape. Each <br /> tube was then marked and placed within an iced, insulated <br /> container for transportation to Priority Environmental Labs <br /> under chain of custody. Certified analyses were performed <br /> for Total Petroleum Hydrocarbons as Diesel (TPH-D) using <br /> EPA Methods 3550/8015 , Total Petroleum Hydrocarbons as <br /> Gasoline (TPH-G) , benzene, toluene, ethylbenzene, and total <br /> xylenes (BTEX) using EPA Methods 5030/8015-8020 , Oil and <br /> Grease (TOG) using SM 5520 D&F, Halogenated Volatile <br /> Organics (HVOs) using EPA Method 8010 , and cadmium, <br /> chromium, lead, nickel , and zinc using EPA Methods 7130 , <br /> 7190 , 7420 , 7520 , and 7950 , respectively . The results of <br /> these analyses are summarized in the following table: <br /> Table 1 <br /> Analytical Results of Soil Samples Acquired from <br /> the Soil Storage Piles at 275 Grant Line Road <br /> on August 24, 1994 <br /> Sample No. TPH-D TPH-G B T E X TOG <br /> (ppm) (ppm) (ppb) (ppm) <br /> ----------------------------------------------------------- <br /> SP-Center N.D.
