Geosyntec <br /> consultants <br /> 5. REPORTING AND SCHEDULE <br /> Results of the soil vapor sampling will be documented in a Soil Vapor Investigation Report. The <br /> report will describe soil vapor probe installation and sampling procedures, groundwater sampling <br /> procedures, present a summary of analytical results, and provide a discussion of results at the Site <br /> based on the findings of this investigation. <br /> The report will also include an assessment of the protectiveness of the 2005 Threshold <br /> Concentrations, taking into account the analytical results obtained by the investigation and the <br /> Site-specific correlation factors developed after interpretation of these results. The need to update <br /> Threshold Concentrations will be discussed, if warranted, following receipt of analytical results <br /> and development of Site-specific correlation factors. <br /> It is assumed that field work can begin following CRWQCB's review and concurrence of this <br /> Work Plan,pending receipt of necessary permits. The field work is expected to take approximately <br /> one week and will be completed in one mobilization. The laboratory analytical data obtained from <br /> field work will be evaluated and a report documenting the results will be compiled into a draft <br /> report and submitted to the CRWQCB within 60 days after Geosyntec's receipt of all analytical <br /> results. <br /> Work Plan for Vapor Intrusion Investigation 11 July 30,2021 <br />
