Box 1500 <br /> French Camp, CA 95231 <br /> CONDITIONAL APPROVAL, GROUNDWATER WORKPLAN, FRENCH CAMP RV PARK <br /> AND GOLF COURSE, SAN JOAQUIN COUNTY <br /> I have reviewed the September 2006 Groundwater Monitoring Well Installation Workplan, <br /> prepared by Nolte Associates, Inc. The workplan was prepared to characterize groundwater <br /> quality as part of preparation of a Report of Waste Discharge (RWD). After reviewing the <br /> workplan, I have the following comments: <br /> • The wastewater storage pond likely infiltrated significant amounts of treated wastewater. <br /> That infiltrated wastewater may have impacted groundwater quality. As a result, Wells <br /> MW-1 and MW-2, located in the reserve disposal area may have been impacted by that <br /> discharge. Please propose a monitoring well network that will provide groundwater <br /> quality data upgradient of the site discharges. <br /> • Please specify the hollow stem auger diameter to be a minimum 8-inch diameter to <br /> maintain the two-inch minimum annular seal required by California Well Standards, <br /> Bulletin 74-90, Part 2, Section 9, C. <br /> • Please surge the filter pack before installation of the bentonite transition seal as <br /> recommended by San Joaquin County Environmental Health Department Well <br /> Standards, Section 13.10.8. <br /> • The well screens should be installed based on historical groundwater elevations and field <br /> conditions. The wells should be constructed to monitor the first saturated interval <br /> encountered in the borehole. However, due to the location of Wells MW-3 and MW-4 in <br /> the proposed dispersal areas, construction of an adequate seal is very important. <br /> • Please add trihalomethanes, manganese, hardness, and total coliform organisms to the <br /> list of analytes in Table A-1. <br /> Please address the items described above prior to installation of the groundwater monitoring <br /> wells. <br /> California Environmental Protection Agency <br /> 0 Recycled Paper <br />
