Weber Ave., Third Floor <br /> Stockton, CA 95202 <br /> Dear Mr. Rowe: <br /> Subject: Quarterly Monitoring Results Update At Disco, August 1997 to July 1998 <br /> Enclosed is a summary of the monitoring results at Disco. Included are new groundwater <br /> contour maps for each sampling from August 1997 through July 1998, as well as the previously <br /> submitted contour maps (Appendix 1). Since October 1995, the groundwater flow direction has <br /> continued to be in a south to southeasterly direction. Also included is an updated tabulation of <br /> all monitoring data. <br /> CH2M Hill discusses some high groundwater levels as possible problems with the monitoring <br /> well casings and recommends that all wells be re-surveyed to ensure that the groundwater <br /> elevation measurements are accurate. We will have the wells re-surveyed. <br /> The next quarterly monitoring event is scheduled for Monday and Tuesday,November 9-10, <br /> 1998. In the future, we will include the groundwater contour map and data tabulation with each <br /> Quarterly Monitoring Report. <br /> If you have any questions, I can be reached at 925-944-7276. <br /> Sincerely, <br /> Richard Fish <br /> Environmental Manager, Western Region <br /> cc: Margaret Lagorio - San Joaquin County PHS/EHD <br /> Elizabeth Dodge - CH2M Hill—W/O Attachment <br /> Steve Ronzone -DMF <br /> Susan Flieder -DMF <br /> Steve Balling -DMF <br />
