r . <br /> J. Y <br /> 1, H. KLEINFELnER &ASSOCIATES <br /> 4 .2 SOIL SAMPLING PROCEDURES <br /> soil samples were collected to obtain a more accurate lithologic <br /> log, and for possible future chemical analysis . No soil samples <br /> were collected for chemical analysis at the present time. <br /> Soil samples were collected by advancing the boring to a point <br /> immediately above the sampling depth and then driving a Modified <br /> California sampler lined with three brass tubes into the <br /> undisturbed soil. The sampler was then removed from the bottom <br /> of the boring and the bottom (third) tube sealed with aluminum <br /> foil and tight fitting plastic caps. The sealed tube was <br /> immediately stored in an iced cooler and at the end of field <br /> operations placed in refrigerated storage under chain-of-custody. <br /> The soil samples were retained in refrigerated storage to allow <br /> r for chemical analysis at a later time if desired. A completed <br /> copy of the chain-o€-custody form for the samples placed in <br /> refrigerated storage is included in Appendix B of this report. <br /> 4.3 MONITORING WELL INSTALLATION <br /> 5.� <br /> Ground water monitoring wells PSW-5, MW-6, and MW-7 were <br /> constructed in the three soil borings at the completion of <br /> drilling and logging of each soil boring. Monitoring well MW-5 <br /> - was constructed in the soil `coring located between the production <br /> well and MW-3. Monitoring well MW-6 was constructed in the soil <br /> u boring located along the north wall of the main warehouse south <br /> of MW-3 .
