DER <br /> the <br /> the depth to groundwater in the vicinity of the Site has been 12 to 20 feet, and the groundwater <br /> flow direction has been noted as west to 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 CNP and other nearby properties, groundwater flow <br /> beneath CNP has shown varying flow directions often differing from the 'regional' flow <br /> directions as noted above. <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 summarized in Text Table 1 and <br /> ' historical groundwater flow directions noted at the CNP facility (Appendices, Table 2). <br /> 1 <br /> 101486.7/SAC14R02453 Page 5 of 14 July 25, 2014 <br /> ©2014 Kleinfelder <br />
