Mr. Mike Lecision - 2 - ,-/ 25 June 2001 <br /> Groundwater cleanup goals for Cr+6, therefore, will be either background or the lowest <br /> established criteria. Cleanup goals for other compounds that exceed water quality objectives <br /> will be determined in the same manner. <br /> 3. Groundwater at this site contains Cr+6 pollution at concentrations well above water quality <br /> criteria. We request that DWG submit a work plan and time schedule to conduct a soil and <br /> groundwater investigation to completely define the groundwater pollution at this site. The <br /> work plan shall be prepared in general accordance with the enclosed Items to be Included in a <br /> Site Assessment Work Plan. <br /> 4. The QMR shows that Cr+6 concentrations for groundwater samples collected from nearby <br /> municipal drinking water wells (WP-1, 2 and 3)were below the detection limit of 5.0 µg/1. <br /> This is valuable information for the City of Stockton. Please send Mr. Ed Formosa of the <br /> City of Stockton, Department of Municipal Services copies of future reports that contain <br /> analytical results for the municipal drinking water wells. <br /> By 31 July 2001, please submit a work plan and time schedule to conduct a soil and groundwater <br /> investigation. <br /> If you have any questions, you may contact me at(916) 255-3082. <br /> MAR SERRA <br /> Private Sites Cleanup Unit <br /> cc: Mr. Ed Formosa, City of Stockton, Department of Municipal Utilities, Stockton <br /> Ms. Margaret Lagorio, San Joaquin County Environmental Health Department, Stockton <br /> Ms. Jeanne Homsey, ATC Associates, Modesto <br />
