The water sample analysis detected zinc <br /> at 12 ppm and results were below detection limits for lead, <br /> chromium, phosphate, and cyanide. <br /> On April 18 , 1985, the DOHS collected pond water and sludge <br /> samples. The sludge sample analyses detected barium at 44.5 ppm, <br /> chromium at 104 ppm, copper at 64 ppm, nickel at 2,290 ppm, lead <br /> at 82 ppm, and zinc at 3,270 ppm. Sludge samples were extracted <br /> using the wet extraction test as described in the California <br /> Assessment Manual; the resulting analyses detected chromium at 5 <br /> ppm, nickel at 200 ppm, lead at 2.23 ppm and zinc at 1 ,240 ppm. <br /> The sludge was analyzed for base-neutral priority pollutants <br /> using EPA Method 625, and the results were none detected for all <br /> constituents except for butyl benzyl phthalate at 260 ppm and Bis <br /> ( 2-ethyl hexyl ) phthalate at 34 ppm. The pond water sample <br /> analysis detected zinc at 3.2 ppm and all other metals below 1.3 <br /> ppm. Water sample analyses for base-neutral priority pollutants <br /> were none detected for all constituents. <br /> No other previous investigations have been conducted on this site <br /> with respect to ground water, geology or a pond assessment. <br />
