JVM ASSOCIATES <br /> WKA No 1735 02 <br /> June 15, 1994 <br /> Page 2 <br /> disposable bailer Water from the disposable bailer was decanted into appropriate sample <br /> containers provided by the laboratory <br /> The samples were immediately placed in an ice-chest with ice and submitted under chain-of- <br /> custody to a California-certified laboratory for analysis of Total Petroleum Hydrocarbons (TPH) <br /> using Modified EPA test method 8015, and Benzene, Toluene, Ethylbenzene and Total Xylenes <br /> (BTEX) using EPA test method 8020 <br /> The 3 112-inch diameter PVC bailer was cleaned prior to purging each well with a solution of <br /> trisodium phosphate and distilled water to minimize the potential for cross-contamination All <br /> water removed during sampling and purging operations was placed in sealed and labeled 55- <br /> gallon drums and stored on site <br />. No free product was observed in monitoring wells MW1 through MW3 Laboratory analytical <br /> results for water samples obtained from MW1, MW2 and MW3 revealed no detectable <br /> concentrations of TPH as gasoline, diesel, motor oil nor BTEX Analytical results for ground <br /> water samples obtained from the three on-site monitoring wells are summarized in Table 2 <br /> The fourth quarter of ground water sampling is scheduled for June, 1994 A summary of our <br /> findings will be transmitted upon completion of laboratory testing Please call if you have any <br /> questions regarding this report <br /> Wallace ■ Kuhl & Associates, Inc <br /> * <br /> Robert Kull Eric Hubbard <br /> Staff Engineer Registered Geologist #4807 <br /> RK'KB EH rbn <br /> xotu735-02 Qrs <br /> WALLACE•KUHL <br /> Its„cfd Oxy, &ASSOCIATES INC <br />
