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. Three <br /> will be located in the alley between 2nd & 3rd Sts. , approxi- <br /> mately 75 feet west of S. Walnut Ave. and three will be located <br /> on S. Acacia Ave. , approximately 150 feet south of the southern <br /> boundary at 923 South Acacia. They will be drilled to a depth <br /> of 40 feet, 12,0 feet., and 240 feet at each location. The seventh <br /> well will be located in the alley between N. Walnut and <br /> N. Stockton, approximately 120 feet north of Main St. where- <br /> currently two•;monitoring wells are located. This well will be <br /> drilled to a depth of 240 feet. All wells will be finished off <br /> flush to the ground. Each well will be locked to prevent <br /> unauthorized access.
