DUDEK <br />Evaluation of Soil and Soil Vapor Data <br />Dudek will evaluate the results of the soil vapor sampling data and conduct a screening level risk <br />assessment using California Regional Water Quality Control Board Environmental Screening Levels, <br />EPA Regional Screening Levels, and DTSC HERO Note 3 Screening Levels. <br />If risks exceed those allowable for the target land use criteria, additional sampling may be necessary <br />and/or a formal human health risk assessment (HHRA) may be recommended. <br />The findings of the limited Phase II ESA will be presented in a letter report that will include a summary <br />of the work performed, any variances from the work plan, tabulated data, figures depicting the sample <br />locations and areas of concern, soil boring logs, and laboratory analytical results. If the findings of the <br />limited Phase II ESA report indicate a potential impact of vapor migration or other potential impacts on <br />the site, the report will also contain recommendations for further work. Recommendations may include <br />remediation, vapor mitigation design, or other investigations to appropriately determine the nature and <br />extent of any contamination. <br />Project Cost <br />Table 2 presents the cost for the aforementioned scope of work. <br />Table 2.
