i <br /> r 'ls - <br /> i <br /> KE1-P86-084SS <br /> November 12 , 1986 <br /> Page 2 <br /> On November 6, 1986, KEI obtained three (3) composite soil <br /> samples (designated as COMP #1 , COMP #2 and COMP #3) . Each <br /> composite sample consisted of four (4) grab samples taken at <br /> various locations and depths. The soil samples were <br /> collected in 2-inch by 6-inch clean brass tubes which were <br /> then capped , tape sealed and placed in ice chest for <br /> subsequent delivery to the Sequoia Analytical Laboratory of <br /> Redwood City for analyses. <br /> The results of the October 10 and November 7 soil analyses <br /> are summarized below and are attached to this report . <br /> Total <br /> Composite Hydrocarbons Benzene Toluene Xylene <br /> _ Sampled m (ppm ,,, (Ppm) ppm) <br /> Comp.

Based on the analysis of the November <br /> 7, 1986 samples, the soil aeration resulted in a significant <br /> decrease in hydrocarbon concentrations. The low level <br /> contaminants in the soil will not pose any impact to the <br /> environment . Therefore , no further sampling is necessary . <br />
