The top of the <br /> screened interval for monitoring wells DMW1 through DMW4 is between 61 and 64 feet <br /> bgs. The top of the screened interval for DMW5 is 50 feet bgs. This has created a <br /> condition where wells 1-4 are 15 to 17 feet over screen and well 5 is 4 feet over screen. <br /> Wells that are over screen usually produce results that are not representative of the <br /> aquifer of concern. Installation of wells screened for a shallower static groundwater <br /> elevation may be required as groundwater approaches impacted soil. <br /> PHS/EHD was not notified of the monitoring scheduled for July 11, 1997. Please provide <br /> PHS/EHD with 48 hours advance notice of all future monitoring. <br /> PHS/EHD recommends that the results of all analyses and monitoring data be tabulated <br /> in a manner that will display compliance with the post remedial monitoring program. <br /> Please contact Steven Sasson, Senior REHS, at (209) 468-3459, if you have any <br /> questions. <br /> Donna Heran, REHS, Director <br /> Environmental Health Division <br /> c <br /> Steven Sasson, Senior REHS Margar t Lagorio, REHS <br /> Site Mitigation Unit Supervisor <br /> ss <br /> cc: Elizabeth Thayer, CVRWQCB <br /> cc: Kevin Brown, Dames and Moore <br /> cc: Bernie Sloop, American Moulding and Millworks <br /> A Division of San Joaquin County Health Care Services <br />
