Setness <br /> HARTMANN& SETNESS <br /> 3203 West March bane,Suite <br /> Stockton,CA 95219 <br /> Subject: STOCKTON PLATING <br /> 632 South EI Dorado Street,Stockton,California <br /> Dear Mr. Setness: <br /> On 29 January 1998, representatives of Advanced GeoEnvironmental, Inc. (AGE) met with Mr. <br /> Harlin Knoll and Ms. Margaret Lagorio of the San Joaquin County Public Health Services - <br /> Environmental Health Division (PHS-EHD) to discuss the proposed soil.and ground water <br /> remediation system for the referenced site. <br /> The following is a brief summary of the meeting: <br /> 1. Recent policy changes at the State and local regulatory levels have required vertical <br /> definition of soil contamination. Vertical assessment of soil contamination has not been <br /> performed at the Stockton Plating site. Therefore, at least one soil boring will be required <br /> near the former UST excavation that extends .below first encountered ground water <br /> (approximately 50 to 70 feet). <br /> F 2. Based upon analytical results of recently collected ground water samples,ground water flow <br /> direction and the rise in relative ground water elevation,AGE recommended the collection <br /> of three grab ground water samples and the installation of one additional }round water <br /> monitoring;well(Quarterly Report-December 1997.One of the grab ground water samples <br /> should be collected northwest of monitoring well MW-3.The PHS-EHD concurred with the <br /> recommendations. <br /> 3. A work plan should be submitted by AGE for completion of the vertical assessment of <br /> contamination as well as collection of grab ground water samples and installation of one <br /> additional ground water monitoring well. <br /> 4. Installation of the remediation system at the site should be delayed until the additional <br /> assessment has been completed. Upon completion of the additional assessment, any <br /> L BLit 49V 6OZ HNOU i AN3099 (330NVACIV NOaA WVLS=0 L 866 L-BO--Z <br />
