i r , l <br /> Ms. Margaret Lagorio <br /> Page 8 of 8 <br /> in this boring, no information was obtained concerning shallow groundwater quality east of the <br /> source area. <br /> The contaminant mixture, groundwater flow and the plume geometry all suggest that the source <br /> of the contamination in Knowles wells MW3, MW4 and MW14 is toward the west. In the <br /> absence of any other identified release that source is almost certainly the Top Filling Station. We <br /> find it inconsistent that PHS/EHD has not required the Responsible Party for the Top Filling <br /> Station to install properly constructed monitoring wells east of their source area yet has required <br /> Knowles to sample wells affected by the Top Filling release. <br /> PHS/EHD has indicated that they will make no effort to assist in the transfer of responsibility for <br /> sampling these wells. The Responsible Parties for the Top Filling Station will be asked to assume <br /> all responsibility for these wells. Should they decline, legal action may be initiated. <br /> PROTOCOLS, PERMITTING AND REPORTING <br /> All field activities will be conducted in accordance with Ground Zero's Quality Assurance/Quality <br /> Control and Site Specific Health and Safety Plans on file with PHS/EHD. Monitoring well <br /> construction and destruction permit applications will be submitted under separate cover following <br /> approval of this Workplan. Following the completion of field activities and receipt of analytical <br /> results a technical report will be submitted to PHS/EHD and RWQCB describing the <br /> methodology and results of the investigation and containing recommendations for additional work <br /> as appropriate. <br /> If you have any questions or comments regarding this correspondence please contact Ground <br /> Zero at your earliest convenience. <br /> Respectfully, �EED 'GFp <br /> Ground Zero Analysis,, Inc. <br /> GREGORY P. <br /> N <br /> � <br /> Gregory P.
