Box 2009 RQPv4' N ,II: HC <br /> Stockton, CaliforniaPE ,��� V?��`� <br /> Subject: Enclosed Summary of Findings, Former Barrel Storage <br /> Area, Brookside Development Site, Stockton, California <br /> Dear Ms. Ratliff: <br /> In response to a Notification of Hazardous Waste Discharge <br /> (#89-231) issued by your agency on November 8 , 1989 , we have <br /> enclosed for your information a summary of Levine• Fricke's <br /> findings from previous field investigations which were performed <br /> as part of a due diligence environmental site assessment of the <br /> subject property. This summary had been previously submitted to <br /> the Central Valley Regional Water Quality Control Board in <br /> response to their request for additional information concerning <br /> this issue. <br /> This portion of our environmental assessment focussed on the <br /> vicinity of a former barrel storage area and garbage pit, located <br /> next to a former milk barn at the Site. A brief summary of these <br /> findings was presented in our "Work Order Number 1, Soil and <br /> Ground-Water Investigation in the Vicinity of Diesel-Affected <br /> Soil and Former Barrel Storage Area, " dated August 25, 1989, <br /> which was submitted to you along with our application for a <br /> permit to install five ground-water monitoring wells in this <br /> general area of the Brookside site. <br /> Our findings from our previous investigations indicated the <br /> presence of benzene at a concentration slightly above the <br /> Department of Health Services Action Level for drinking water in <br /> only one grab ground-water sample collected from a test pit in <br /> the vicinity of the former barrel storage area. The results of <br /> additional soil and ground-water sampling and analysis performed <br /> by Levine-Fricke in this area, reported in the attached summary, <br /> indicated that the affected area was localized, and that the <br /> concentrations detected were likely the result of surface <br /> spillage of gasoline. (Total petroleum hydrocarbons as gasoline, <br /> TPHG, were also detected in a ground-water sample collected from <br /> the same test pit at 0. 2 ppm, and in a ground-water sample <br /> 1900 Powell Street, 12th Floor <br /> Emeryville, California 94608 <br /> (415) 652-4500 <br /> Other offices in NEWPORT BEACH and OAKLAND,CA <br />
