ARCADIS GERAGHTY&MILLER <br /> • Applicable cleanup levels based on the numerical objectives designated <br /> in the Basin Plan of the Central Valley Regional Water Quality Control <br /> Board. <br /> The assessment component of the CAP, in addition to that referred to above, <br /> will address the physiochemical characteristic of the constituents of concern, <br /> toxicity, persistence and potential for migration in groundwater. The CAP will also <br /> discuss the hydrogeology of the site and the surrounding area where the <br /> unauthorized release has migrated or may migrate. The current and potential <br /> beneficial uses of the waters beneath the site and vicinity will also be presented <br /> along with the associated background quality of groundwater in the vicinity of the <br /> site. Lastly, the assessment will address the potential effect of residual impacts on <br /> groundwater in the site vicinity. <br /> A feasibility study will be included in the CAP and will evaluate alternatives <br /> for remedying or mitigating adverse effects of the release. As indicated in Title 23, <br /> each alternative will also be evaluated for cost-effectiveness. At least two <br /> alternatives will be identified and evaluated as methods to restore or protect the <br /> beneficial uses of groundwater in the site vicinity. It is the opinion of ARCADIS <br /> Geraghty and Miller that sufficient data is available, from scientific literature <br /> sources and site-specific data at similar sites in California and in the local vicinity <br /> of this site, to conduct the methodology evaluation without implementation of site <br /> pilot testing. The most cost-effective corrective action will be selected and <br /> submitted to SJCPHS as the action to implement. <br /> REPORT <br /> Following completion of the scope of work proposed in this workplan, an <br /> investigation and CAP report will be prepared and submitted to the SJCPHS. The <br /> report will summarize field methodologies used along with findings and conclusions <br /> for this investigation. The report will also contain tables summarizing analytical <br /> results, a site map showing the piezometer location, boring log and piezometer <br /> construction details, copies of all necessary permits to perform the proposed scope <br /> of work, copies of all analytical results, and the CAP. As indicated above, the CAP <br /> will include an assessment of the vertical and lateral groundwater impacts in the site <br /> vicinity,a feasibility study, and applicable cleanup levels. <br /> SCHEDULE <br />
