(AGE) has prepared the <br /> F enclosed Final Remediation Plan(FRP)soil sample plan for the site located at 632 South El Dorado <br /> Street, Stockton, California. A approved by the San Joaquin County - Environmental Health <br /> 't Department soil samples will be collected from four shallow soil borings and analyzed. <br /> Progress/Confirmation Soil Sampling <br /> r when efficient <br /> After approximately six months of operation o y of the'unit has declined or vapor <br /> recovery has become asymptotic, soil samples will be collected from the "core" petroleum <br /> hydrocarbon impacted area. Analytical results of the soil samples will serve to approximate <br /> remaining petroleum hydrocarbon levels and determine if continuing remedial operation is necessary. <br /> Soil samples will be collected utilizing a direct push technology. AGE proposes to advance soil <br /> probe borings in the "core" petroleum hydrocarbon-impacted area at the site to depths of <br /> approximately 40 to 50 feet bsg, using a Geoprobe 5400 soil probing unit. <br /> Discrete soil samples will be collected at five-foot intervals beginning at a depth of 10 feet bsg <br /> utilizing a Geoprobe soil sampling assembly.loaded with pre-cleaned 1.125-inch by 6-inch brass <br /> sleeves. Soil samples will be preserved by covering both ends of the second brass sleeve with Teflon <br /> sheets,plastic end caps and sealed with tape.Each sample sleeve will be labeled with the soil probe <br /> boring location,depth,time,date and sampler's initials. Soil samples will be transported in a cooler <br /> under ice to a DHS-certified laboratory for analysis. <br /> 837 Shaw.Road, Stockton.California 95215 <br /> Telephone (209)467-1006 Fax(209)467-1118 <br />
