Charter Way RO# : 382 <br /> Stockton , CA, 95206 SWRCB-CUF#: 000552 <br /> On July 24 , 2007 , a meeting was held at the offices of the San Joaquin County <br /> Environmental Health Department ( EHD) to discuss the above referenced site and <br /> the June 8 , 2007 , EHD correspondence concerning the site . The meeting <br /> participants were you and Scott Solari from Nomellini Construction , Bob Marty, Bill <br /> Little and Art Deicke from Advanced GeoEnvironmental Inc, and Margaret Lagorio , <br /> Nuel Henderson and Michael Infurna from EHD . <br /> The EHD understands your reasoning for not having MW-3 , 4, 5 , 7 , 8 , 9 , and 11 <br /> destroyed at this time and rescinds that directive . The EHD requests that your <br /> consultant prepare a discussion of the hydrological units shown and discussed in <br /> their reports and justify that the wells that are screened across more than one <br /> hydrological unit do not provide a cross contamination pathway. Please include this <br /> discussion in the work plan to be submitted to the EHD for the next phase of <br /> investigation for the site . <br /> It was agreed at the meeting that remediation of the area of high dissolved <br /> petroleum concentrations , the core, should be started as soon as possible . It was <br /> further agreed that your consultant would submit a work plan to conduct pilot tests <br /> t for feasible remedial alternatives. At the meeting the remedial alternatives of <br /> excavation , dual phase extraction and groundwater extraction were discussed . <br /> Vapor extraction and air sparging have been performed at the site and groundwater <br />( has risen to a level where they are no longer feasible remedial alternatives . EHD <br /> informed you that the most cost effective remedial action should be performed . <br />`r <br /> In addition to an evaluation of remedial alternatives , it was discussed at the meeting <br /> that for now at least three additional deep monitoring wells in different areas of the <br />` site are to be installed to further investigate and delineate the extent of the dissolved <br /> petroleum plume. <br /> f <br /> E <br />
