Compton <br /> City Administrator <br /> 311 W. First Street C 1TV <br /> Ripon, CA 95366 <br /> Dear Mr. Compton: <br /> As you are aware from our recent discussions, we need to install, <br /> and have access to four additional groundwater monitoring wells <br /> on the cityts property in Ripon, CA. These wells are required <br /> by the central Valley Regional Water Quality Control Board <br /> (CVRWQCB) as part of an ongoing investigation to evaluate the <br /> extent of organic chemical migration in the aquifers in the <br /> area. <br /> Pritcher Drilling Company, has been retained by Nestle Foods to <br /> drill these monitoring wells, and they are being provided with <br /> engineering and hydrogeological expertise by the consulting firm <br /> of Camp Dresser and McKee. Both of these firms carry all appro- <br /> priate insurance coverage for this type of work. <br /> These monitoring wells will be located in Ripon, CA. Two (2) <br /> wells will be at 311 First Street (City Hall) , and two will be <br /> located within the southern boundary of the city Park located <br /> at 312 W. Fourth Street. They will be drilled to a depth of <br /> 40 feet and 120 feet respectively at each location and will be <br /> finished off flush to the ground. Each well will be locked to <br /> prevent unauthorized access. Water samples collected from the <br /> well will be analyzed by EPA method with specific emphasis <br /> on the determination of concentrations on: <br /> trichloroethylene, 1,1,1-trichloroethane, trans-1, 2-dichlo- <br /> roethylene, and vinyl chloride. In addition, water level <br /> measurement will also be taken. <br /> Copies of all well drilling/logging data and analytical results <br /> that are submitted to the CVRWQCB will also be forwarded to you <br /> upon request. <br /> Nestle Foods agrees to indemnify you from any loss or expense <br /> arising out of drilling, operating, and maintaining of these <br /> monitoring wells on the city' s property, as contemplated by <br /> this letter. <br /> Please acknowledge your approval for Pritcher Drilling Co. /CDM <br /> to install the above-referenced monitoring wells on your property <br /> by signing on the next page and returning a copy of this letter <br />
