Box 2009 <br /> Stockton, CA 95201 <br /> Subject: Verification of Soil Remediation <br /> 500 Hospital Road <br /> French Camp, California <br /> Dear Ms. Turkette: <br /> Per my discussion on June 10, 1993 with Ms. Diane Hinsen, I am sending this letter to <br /> document the approved soil sampling frequency and protocol for the aerating soil at the <br /> hospital. Based on rough stockpile measurements and truck counts, Kleinfelder estimates that <br /> approximately 2,400 cubic yards of soil are being aerated. The aeration cell is approximately <br /> 300 feet by 200 feet spread approximately 1 foot deep. As we discussed, 48 samples were <br /> analyzed to receive approval to aerate by the San Joaquin Unified Air Pollution Control <br /> District. The maximum reported concentration of TPHg was 37 mg/kg. <br /> Prior to actually sampling the soil, a Kleinfelder representative will qualitatively screen the soil <br /> using a PID. If the qualitative readings are consistently below 5 ppmv, verification samples <br /> will be collected. One sample will be collected for each approximately 100 cubic yards of soil <br /> being aerated. The samples will be collected in six rows with four samples per row. <br /> Immediately after collection, each sample will be sealed with Teflon sheeting and plastic caps, <br /> labeled, logged on a chain-of-custody, and stored in an iced cooler. Each of the samples will <br /> be submitted to Superior Precision Analytical Laboratories, Inc. (Superior) in Martinez, <br /> California. The samples will be composited four into one by the laboratory. The six resultant <br /> samples will be analyzed for TPHg and BTEX. <br /> Kleinfelder appreciates your assistance with this project. Although we are currently projecting <br /> to sample on June 23, 1593, we wiil confirm with you at least two days prior to sampling. <br /> Hugs and kisses to Nicholas. <br /> Sincerely, <br /> LDER, INC. <br /> 41-1 <br /> (7 C <br /> Dana W.
