FIELD INVESTIGATION <br /> A. Drilling and Soil Sampling <br /> Three borings were drilled on-site. The selection criteria for <br /> the boring locations included site history, requirements by WQCB, <br /> and anticipated ground water gradient based on literature review. <br /> It was anticipated that the borings would be completed as <br /> monitoring wells with one well hydrogeologically up-gradient of <br />
