Any monitoring wellslocated within SO feet' of :A <br /> sanitary sewer line will be sampled for fecal coli'forin as per <br /> requ#ed by San Joaquin County Public Health Services. <br /> All work described herein will be completed according to the <br /> health and safety procedures outlined in the site`1.zealth and <br /> safety plan included in Appendix A. A copy of the health and <br /> safety plan will be available on site during all field <br /> operations. <br /> 4.1.1 S'Oil_SamglinQ <br /> Soil sampling will be conducted in general accordancF with AST;4 ' <br /> 1586-84. Using this procedure, .a two-inch O.D. split-barrel <br /> samp-er or a two-inch I.D. California-type sampler is driven into <br /> the soil by a 140-pound weight falling 30 inches. .• After an <br /> initial set of 6 inches, the number of blows required to drive <br /> �J the sampler an additional 12 inches i , known as penetration <br /> i resistance, or the 'IN" value. The N value is used as an empirical <br /> measure.of the relative density of cohesionless sails and the <br /> j consistency of cohesive soils: <br /> Upon recovery, a portion of the soil sample will be placed into a <br /> Zip lock plastic bag and sealed for later screening with a gas <br /> detei or. . Another portion of the soil sample will be used for <br /> classification and description. That part of the soil sample <br /> ' collected in a brass'tube within the California-t' <br /> I . ypa sampler will <br /> be stored in. an iced cooler at approximately 40 C..f'or transport <br /> to the laboratory. <br /> ¢ �3.1.2 Soil Classification <br /> As the samples are obtained in the field, they are classified in <br /> accordance with`the Unified Soil Classification .system (USCs) . <br /> Representative portions of the samples are then returned to the <br /> f laboratory for further examination and for verification of the <br /> field classification.
