The down gradient <br /> extent of the plume, to the north of the site,was established with the installation of monitoring well 10 in <br /> August of 1991. The area that remains to be defined is to the east of the site. The contaminants being <br /> detected in monitoring well 5, the most easterly monitoring well,are at levels high enoughl to warrant <br /> another sampling point further east. <br /> As the remediation system is currently in operation, it is crucial to have the full extent of the <br /> contamination defined. The monitoring wells atz the perimeter of the plume provide useful information on <br /> the range of influence and the efficiency of the remediation system. <br /> Please continue to submit quarterly status reports to this office. In addition to the monitoring well data, <br /> the reports should include information on the status of the remediation system, complete with any <br /> pertinent laboratory data. As a reminder, this office requires 48 hours advanced notice prior to any <br /> sampling activity at the site. <br /> A workplan to investigate the extent of the contamination to the east of the site should be submitted to <br /> this office by July 6, 1992. <br /> If there are any questions, please contact Linda Turkatte, REHS, of my staff at (209) 468-0339. <br /> JogiKhanna, M.D., M.P.H. <br /> ealth Officer <br /> La rie A to la, REHS, gram Manager <br /> Environmental Health Division <br /> LAC/LT:lb <br /> c: CVRWQCB-Beth Thayer <br /> c: Jerry Wilske-Aegis Environmental <br /> 1050 Melody Lane, Suite 160 <br /> Roseville, CA 95678 <br /> A Division of San 3oaquin Counry Health Gare Services <br />
