Attending <br /> the meeting were Sharla Hardy, Wayne Smith and you representing City of <br /> Stockton (COS), Robert Marty and William Little representing Advanced <br /> GeoEnvironmental, Inc. (AGE), Jeanne Homsey representing ATC Associates <br /> (ATC), and Margaret Lagorio and Jeff Wong representing PHS/EHD. The <br /> following is a summary of the site discussions at the meeting. <br /> Fontana Drive at Smith Canal <br /> PHS/EHD requested that the monitoring well referenced in the letter dated <br /> April 4, 2001 from PHS/EHD be installed. PHS/EHD has discussed the <br /> location of this well with Central Valley Regional Water Quality Control <br /> Board. The monitoring well should be installed on the northeast corner of <br /> the property. <br /> 110 W. Sonora <br /> AGE is currently proceeding with the work as proposed in Design Plans <br /> and Specifications for Soil and Groundwater remediation dated October 5, <br /> 2000. PHS/EHD requested samples be collected from the top of the <br /> groundwater in the deepest well on site, RW-1 , as well as from the bottom <br /> of the well in order to establish a baseline for and evaluate the vertical <br /> extent of contamination in groundwater. The water sample from the <br /> bottom of the well should be collected using a bomb sampler. Based on <br /> analytical results of the groundwater samples from RW-1, PHS/EHD will <br /> determine if further sampling of this well is necessary. <br /> 1740 Houston <br /> Although PHS/EHD approved Monitoring Well Installation Work Plan <br /> dated September 17, 2001 prepared by AGE, PHS/EHD is concerned that <br /> the total depth of the proposed borings may not provide definition of the <br /> vertical extent of the contamination. It was discussed that the borings <br /> should be advanced to at least 60 feet below surface grade with a <br /> contingency to advance deeper to collect grab groundwater samples. <br /> A Division of San Joaquin County Health Care Services <br />
