KEI-JE6-031 <br /> September 8, 1986 <br /> Two soil samples were taken using brass tubes at about 4 foot <br /> depth per Mr. Crooks , instruction. The samples were analyzed for <br /> lead, total fuel hydrocarbons (THC) , and Ethylene dibromide <br /> (EDB) . <br /> In addition to contaminated soil excavation and soil <br /> sampling, contaminated ponded water was also removed from the <br /> diked loading service area. The ponded water was pumped into 55- <br /> gallon drums and disposed to approved site. <br /> w On June 17, 1986 a water sample was taken from well E-2, <br /> using a teflon bailer. Prior to sampling water elevation was <br /> measured and the well was purged about 10 well volumes. The <br /> sample was stored in a cool ice chest and transported to the <br /> Sequoia Analytical Laboratory. No odor or free product was <br /> detected during sampling Of well E-2. Groundwater sample was <br /> analyzed for THC, BTX, EDB and lead. The water table elevation at <br /> the .time Of sampling was 10 feet. <br /> On June 24, 1986 one 550-gallon underground tank was removed <br /> and a soil sample was taken under the Supervisio;z of Mr. Crooks. <br /> The sample was analyzed for THC, BTX, lead and EDB. <br /> On August 22, 1986 installed cement curb around the loading <br /> service area and backfilled this area with pea gravel. <br /> ANALYTICAL RESULTS <br /> The results of the laboratory analyses are summarized below: <br /> Sample Lead THCI EDB23 <br /> Description, m BTX <br /> -- _— PPM PPM <br /> Soil #Z - 5.3'- 46. 0 N _ <br /> Soil W2: 12.0 150.0 ND _ <br /> W.O. 1 12. . <br /> 0 130 <br /> <0.05 <0.1y . <0.1.1 <0.1 <br /> (Water E-2) <0.005 <1.0 c0.05 <0.001, <0.001, <br /> [0. 001: <br /> L <br />
