R <br /> Triadf Groundwater Associates <br /> HYDROGEOLOGISTS&GEOLOGISTS <br /> June 5, 1990 <br /> Mr. Greg Lyon <br /> San Joaquin County Public Health Services <br /> Environmental Health Division <br /> P.O. Box 2009 <br /> Stockton, California 95201 <br /> Subject: Installation of Ground-Water <br /> Monitoring Wells <br /> Moore Petroleum Inc. <br /> 5491 F Street <br /> Manteca, CA <br /> Triad Project No. 10-90-481 <br /> Dear Mr. Lyon: <br /> As we discussed earlier today I am proposing that monitoring well <br /> MW-6, which is scheduled to be installed at the subject site on <br /> June 11 or 12 , 1990 be moved from the location proposed in the <br /> Preliminary Hydrogeologic Assessment Report which was submitted by <br /> Delta Environmental Consultants, Inc. (Delta) on September 8, 1989 <br /> to the location shown on the attached map. The new proposed <br /> location would place the well in the northwestern corner of the <br /> property. At this location the well would serve as an up-gradient <br /> well (based on water level elevation data collected on May, 1989) <br /> and be positioned to detect hydrocarbon constituents which could <br /> be entering the site boundaries from off-site. If hydrocarbon <br /> constituents are not detected in this well, ground-water chemistry <br /> data from this well could serve as a guide to background water <br /> chemistry at the site. <br /> If you have any questions concerning the planned location change <br /> for this well, please give me a call. <br /> Sincerely, <br /> TRIAD GROUNDWATER ASSOCIATES <br /> Darrell L.
