r++ <br /> Gasoline cuncentrations decrease to less than 0.1 ppm in the <br /> - northeast, east, and southern portion of the site. It appears that <br /> concentrations between 0.1 and 10 ppm may extend to the northwest <br /> and west off the boundaries of the Manna Pro facility. <br /> 'I <br /> Results of analyses of samples collected from the stockpiled soils <br /> removed from the excavation are summarized in Table 3-3.

Results of the sample analyses of this pile <br /> substantiate that the soil is clean and suited for use as backfill <br /> material. Stockpile #2 is the clean granular fill material brought to <br /> the site from another borrow site. Stockpile #2 was nut included in <br /> this sampling.
