Five of these soil borings were <br /> advanced to depths ranging between 20 and 30 feet. Two additional borings were <br /> advanced to a depth of approximately 45 feet for conversion to monitoring wells. <br /> The location of the borings are shown on Figure 2. Logs of each boring are <br /> included in Appendix A. <br /> The soil borings were distributed around the existing MW-1 monitoring well <br /> location in order to betti9r assess the lateral ana vertical extent of hydrocarbon <br /> contamination in the soils and groundwater as identified during the initial soils <br /> investigation. Details of the drilling and sampling procedures are outlined in <br /> Appendix A. <br /> 4. <br /> 3.2 GROUNDWATER MONITORING WELLS <br /> ti.. <br /> ii <br /> Two soil borings were converted to groundwater monitoring wells, MW-5 and <br /> ^' MW-6, (Figure 2). The locations were selected to further evaluate the lateral <br /> migration of the groundwater contamination found in MW-1 in the local <br /> downgradient direction (south), and to confirrra the presence or absence of <br /> contaminant migrat�.on to Zhe west. <br /> w Wells MW-5 and MW-6 were developed and sampled for analysis of previously <br /> r , <br /> targeted hydrocarbons and chlorinated solvents.
