r <br /> Former Chevron Station #9-4054 <br /> January 15, 1996 <br /> h <br /> the sample collected from well KF-3. <br /> Each well was constructed with 4-inch diameter PVC to approximately 30 feet bsg. The screen interval <br /> consisted of 0.020 inch slots and extended from approximately 15 to 30 feet bsg for each well. <br /> In March 1995, the wells were monitored and sampled. Depth to groundwater was approximately 16 feet <br /> bsg (3 feet higher than the December 1994 monitoring data). The gradient was 0.003 and the flow <br /> direction had shifted to the southeast (was to the east during the December I994 monitoring event). <br /> Analytical results indicated that all the wells contained detectable concentrations of TPHg and BTEX. <br /> The TPHg concentrations ranged from 8,100 to 20,000 ppb and the benzene concentrations from 2,000 <br /> to 2,500 ppb. The highest concentrations were detected in the sample collected from well KF-3. <br /> Upgradient Environmental Consultants has recommended additionalwells be installed at the site in an <br /> attempt to delineate hydrocarbon-impacted groundwater. It is our understanding that additional work has <br /> not been performed at the site to date. <br /> BOULEVARD AUTO SITE <br /> The following information for this site was obtained from Mr. Michael Infurna of the San Joaquin County <br /> Public Health Services (SJCPHS). To date there has not been any environmental work performed at the <br /> site. SJCPHS has requested a work plan for a subsurface investigation be submitted their office. <br /> Two USTs were removed from the Boulevard Auto site (date unknown). These USTs appeared to be in <br /> poor condition upon removal. A sheen was present on water within the UST pit. According to SJCPHS, <br /> there is not any other information pertaining to this site. <br /> At Chevron's request, G-R can submit the required application to the SJCPHS for further review of these <br /> sites. If you should have any questions please call our office at (510) 551-7555. <br /> Sincerely, <br /> Gettler-Ryan Inc. <br /> 4Q <br /> egGurss <br /> Project Manager <br /> Attachment: Copy of Fourth Quarter Report, Kwikee Foods (dated January 15, 1995) <br /> Copy of First Quarter Report, Kwikee Foods (dated April 21, 1995) <br /> CH94054.LTZ 2 <br />
