Soil samples will be collected from the <br /> side walls and bottom of the excavation to confirm the extent of contamination. The samples will <br /> be analyzed for TPH-d and BTEX and the results will be forwarded to PHS/EHD. <br /> PHSIEHD does not recommend the use of a backhoe as an assessment tool. A backhoe is limited <br /> to a depth of 20 feet. Contaminated soil plumes have been known to extend to groundwater which. <br /> in this area is at approximately 50 feet below grade. Corrective action which is not directed by <br /> PHSIEHD may not be eligible for reimbursement by the SWRCB reimbursement fund. <br /> If you have any questions please contact Steven Sasson, RENS, at(209)468-3459. <br /> Donna Heran, REHS, Director <br /> E it mental Health Division <br /> e assn, enior R HS Margaret Lagorio, Rl=HS <br /> LOP/Site Mitigation Unit IV Supervisor . <br /> :Ib i <br /> c: SWRCB, Underground Storage Tank Section - Mel Jacobo <br /> c: RWQCB, Central Valley Region -Pat Anderson <br /> c: United Pacific Environmental -Scott Strong <br /> it <br /> A Division of San Joaquin County Health Care Services <br />
