(KLKL E/NFELOER <br /> Bright People Fight Solutions. <br /> The general depth and direction of regional groundwater flow in the area of the site, based on <br /> reports issued by the San Joaquin County Flood Control and Water Conservation District show <br /> the groundwater elevation ranges between 0 and 10 feet relative to sea level and a depth to <br /> groundwater approximately 10 to 20 feet below the ground surface (bgs). The groundwater <br /> flow direction is generally to the northwest. <br /> Groundwater depth and flow direction may be influenced by local pumping, rainfall, and <br /> irrigation patterns. With the nearby groundwater extraction at Sharpe Army Depot, local <br /> irrigation, well pumping and recharge at California Natural Products (CNP) and other nearby <br /> properties, groundwater flow beneath CNP has shown varying flow directions often differing <br /> from the "regional" flow directions. <br /> According to a file review of Sharpe Army Depot records on file with the California State <br /> Department of Toxic Substances Control, Sharpe has eight extraction wells for withdrawal of <br /> the shallow (A-Zone) water within approximately 1200 feet of the northeast corner of the CNP <br /> plant. Those wells are EWA1, EWA3, EWA5, EWA6, EWA7, EWA8, EWA9, and EWA10. <br /> Extraction of groundwater is likely impacting shallow groundwater flow, and further may be <br /> responsible for the variance between the flow directions and historical site groundwater flow <br /> directions noted at the CNP facility (Table 2). <br /> 00101486.8/SAC15R19291 Page 8 of 17 May 6, 2015 <br /> ©2015 Kleinfelder <br />
