water bodies within one mile of the site include the Calaveras River to the north and the <br /> Stockton Diverting Canal to the south. <br /> 2.7 Proximity of Private, Municipal and Irrigation Wells: <br /> If needed, a survey of all active, inactive, and destroyed water supply and monitoring wells <br /> within a one-half mile radius of the project site, will be conducted. <br /> 3.0 METHODS AND PROCEDURES <br /> A subsurface site investigation will be performed to help characterize current soil conditions <br /> beneath the former tanks. wJbe.investigation will consist of drilling and sampling 2 soil borings, <br /> boring abandonment, and subsequent laboratory analysis. <br /> i <br /> All field activities will be conducted in accordance with the site specific Health and Safety Plan <br /> (Appendix II). The field investigation will be conducted under the supervision of a California <br /> Registered Geologist. <br /> A problem assessment report summarizing the findings of the investigation will be prepared <br /> according._to RWQCB guidelines, under the_supervision.of the registered geologist The —�, u <br /> registered geologist will review and sign the problem assessment report. <br /> 3.1 Soil Borings <br /> Proposed soil boring locations will be in the former tank pit area-as shown on Figure 2.
