' TPH-D (IT, 2002b) Soil sample analytical data is included in Table 1 and depicted in Figure 3 <br /> Groundwater sample analytical data is included in Table 2 and depicted in Figure 4 <br /> In a letter dated June 11, 2002, the SJCEHD requested the completion of a work plan to address <br /> site assessment The following work plan addresses procedures for investigation of site soil and <br /> groundwater quality A copy of the letter is included in Appendix A <br /> I <br /> 2.0 Scope of Work <br /> This work plan addresses proposed procedures for evaluating soil and groundwater quality on the <br /> site Planned activities include drilling and sampling of up to six direct push soil borings, <br /> collection and analysis of soil and groundwater samples, and evaluation of the field and analytical <br /> data <br /> 3.0 Field Investigation <br />' The following methods and procedures will be used to complete the proposed field investigation <br /> 10 <br /> 3.9 Soil Borings <br /> Prior to initiation of field activities, a site-specific health and safety plan will be developed to <br /> outline safety measures to be implemented during field activities A copy of the health and safety <br /> Iplan is included in Appendix B Underground Service Alert (USA) will be contacted and notified <br /> of the anticipated drilling locations and date of field activities Additionally, an independent utility <br /> locating service will be subcontracted to further assist in locating utilities within the anticipated <br /> drilling locations <br /> U to six soil borings will be advanced at select locations of the site utilizing direct push sampling <br /> P g � g P p g <br /> equipment Proposed soil boring locations are depicted in Figure 5 The soil boring locations <br /> were selected in order to attempt to ascertain the lateral and vertical extent of petroleum <br /> hydrocarbon migration from the former UST system Three of the proposed bonngs will be <br /> located immediately adjacent to the former UST excavation to further define petroleum <br /> hydrocarbon concentrations in the immediate area of concern The remaining three borings will <br /> Ibe placed further from the former UST system to attempt to determine if any of the petroleum <br /> hydrocarbons have migrated Soil boring locations are approximate and may be relocated based <br /> Ion subsurface conditions encountered during field activities <br /> • <br /> ICNCiJ17-24-0210 SHAREIU8'nO2-0061 doc 2 <br />
