The results of the limited site <br /> assessment indicated elevated levels of lead in selected soil samples collected. In a San Joaquin <br /> County Environmental Health Department(EHD)letter dated 06 March 1991;it was requested that <br /> further investigation of the elevated levels of lead detected in the soil be conducted before issuance <br /> of any permits regarding the site. <br /> DRILLING AND SOIL SAMPLE COLLECTION <br /> AGE proposes to advance six soil probe borings using non-mechanical methods.Probe borings will <br /> be advanced using a hand auger with a 3-inch cutting bit.Each soil boring will be advanced to 4 <br /> vertical feet below surface grade(bsg). Soil samples will be collected at 2-feet and 4-feet bsg using <br /> a slide hammer. Discrete soil samples will be collect using 6-inch brass sleeves. Upon sample <br /> retrieval, the ends of each sleeve will be covered with Teflon sheets, capped and sealed with tape. <br /> Proposed probe boring locations are illustrated in Figure 2. <br /> 837 Shaw Road, Stockton, California 95215 <br /> Telephone(209)467-1006 Fax (209)467-1118 <br />
