Mr. Clint Rogers 31-0355 <br /> June 2, 1992 <br /> Page 2 <br /> SAMPLING AND ANALYTICAL RESULTS <br /> The results of the monitoring and laboratory analyses of <br /> ground water samples for this quarter, as well as the results <br /> of previous monitoring and sampling events, are summarized in <br /> Table 1. A site plan showing depth to water measurements is <br /> presented in Figure 2 . <br /> No liquid-phase hydrocarbons or sheen were observed in any of <br /> the ground water samples. Monitoring wells EA-1, EA-2, EA-3 <br /> and EA-4 were dry; as a result, the ground water gradient <br /> beneath the site could not be determined. The official <br /> laboratory reports and chain of custody records are included <br /> in Appendix A. <br /> Please call John De George at (510) 734-8134 if you have any <br /> . questions regarding this report. <br /> Sincerely, <br /> ALTON GEOSCIENCE, <br /> "+L Lar.- 4�.nj� I <br /> John De George <br /> Staff Geologist <br /> (:f•y ` <br /> Robert E.
