Upon being returned to grade, the contents of each bailer <br /> were transferred into Volatile Organic Analysis (VOA) vials <br /> and one amber glass liter bottle . Each container was <br /> promptly covered with a teflon-lined screw cap, labeled, <br /> and placed in an iced, insulated container for trans- <br /> portation to Priority Environmental Labs under chain of <br /> custody . Subsequent analyses were performed for Total <br /> Petroleum Hydrocarbons as Diesel (TPH-D) , Total Petroleum <br /> Hydrocarbons as Gasoline (TPH-G) , benzene , toluene, ethyl- <br /> benzene, and total xylenes (BTEX) using EPA Methods 3510/ <br /> 8015 and 5030/8015-8020 ( 602 ) , respectively. <br /> The soil profile encountered while advancing boring EP-1 <br /> consisted of 6 inches of concrete and gravel underlain by <br /> very moist , light-brown silty clay becoming slightly moist <br /> light-brown silty clay with rust streaks at approximately 3 <br /> feet below grounds surface (bgs) . Slightly moist , light <br /> brown silty clay with light-olive colored streaks was <br /> present to 5 feet . Light-olive colored, compacted dense <br /> clay was encountered between 5 and 7 feet bgs An odor ,✓ <br /> consistent with that of fuel hydrocarbons was detectable at <br /> 5 feet- becoming intense at 6-7 feet . Silty sand <br /> encountered between 7 and 7 . 5 feet was underlain by a pea <br /> gravel and sand mixture to 8 feet . This mixture was <br /> saturated with dark-colored, malodorous oil,. The soil <br /> beneath was fine sand that continued to the bottom of the <br /> bore hole at 9 feet . Groundwater was encountered at <br /> approximately 7 feet . <br /> The soil profile encountered while advancing boring EP-2 <br /> consisted of 6 inches of concrete and gravel underlain by <br /> loose, slightly moist sand and gravel to I foot bgs <br /> Slightly moist , light-brown silty clay with rust streaks <br /> was present to approximately 4 feet where the rust streaks <br /> became light-olive colored. Light-olive colored dense clay <br /> containing little moisture was present between 4 5 and 6 <br /> feet . Moist , dark-colored silty clay with streaks of sand <br /> was present between 6 and 7 feet . Very moist , dark-colored <br /> fine-silty sand was present between 7 and approximately 8 . 5 / <br /> feet . An odor consistent with that of fuel hydrocarbons as ✓ <br /> present in this layer . Fine sand was encountered between <br /> 8 . 5 and 9 feet . Groundwater was encountered at approx- <br /> imately 7 feet . <br /> The soil profile encountered while advancing boring EP-3 <br /> consisted of 6 inches of concrete and gravel underlain by <br /> light-brown silty sand containing little moisture . Silty- <br /> clay containing little moisture was present between 1 and 3 <br /> feet . This was underlain by slightly moist , very light- <br /> brown clay to 6 feet . Slightly moist, light-brown silty <br /> clay containing rust streaks was present between 6 and 7 <br /> feet and was underlain by moist , light-olive colored silty <br />. clay between 7 and 8 feet Dark-grey, saturated, fine <br /> Page 3 <br />
