SUMMARY OF OTHER ENVIRONMENTAL ACTIVITIES PERFORMED DURING THE PAST QUARTER The direction of groundwater flow and hydraulic gradient have been calculated for the September , 1994 sampling event . Groundwater continues to flow to the northeast . information regarding the methodology used to determine the direction of flow and hydraulic gradient is presented in Appendix B . "'he soil storage piles maintained on site have been recovered monitored to confirm that the polyethylene sheeting covers remain intact , New sheeting has been placed on the soil as necessary . The soil storage piles were also sampled for certified laboratory analyses on August 24 , 1994 at the direction of Mr . Michael Infurna . The results of these analyses are to be submitted in support of the application to bioremediate the subject soil at the Pestana Trust property located across Grant Line Road at 2360 East Street . Each of the two discrete soil samples was acquired by driving a 1 . 9 inch diameter by 6 . 0 inch long clean brass tube into the soil until each tube was completely filled with consolidated material . Upon being withdrawn from the soil , the ends of each tube were covered with aluminum foil , fitted with plastic caps , and sealed with duct tape . Each tube was then marked and placed within an iced, insulated container for transportation to Priority Environmental Labs under chain of custody . certified analyses were subsequently performed for Total Petroleum Hydrocarbons as as Diesel (TPH-D) using EPA Methods 3550/8015 , Total Petroleum Hydrocarbons as Gasoline (TPH-G) , benzene , toluene, ethylbenzene, and total xylenes ( BTEX) using EPA Methods 5030/8015-8020 , Oil and Grease (TOG) using SM 5520 D&F, Halogenated Volatile Organics (HVOs ) using EPA Method 8010 , and cadmium, chromium, lead, nickel , and zinc using EPA Methods 7130 , 7190 , 7420 , 7520 , and 7950 , respectively . The results of these analyses are summarized in the following table : Pace 10
