CPTADVANCEMENT <br /> CPT soil borings will be advanced to a depth of 80 feet bsg or until refusal is <br /> encountered utilizing a 25-ton truck- mounted CPT drill rig equipped with 2-inch diameter <br /> �i hollow-stem rods . At all boring locations , the first soil boring will utilize a hydraulic ram <br /> to advance a cone penetrometer to the desired depth . Soil parameters such as cone <br /> 1 bearing , sleeve friction and pore water pressure will be measured as the cone <br /> penetrometer is advanced . Rinseate generated during drilling activities will be <br /> containerized in properly labeled Department of Transportation (DOT)-approved 55- <br /> gallon drums , and stored on-site in an area lacking public access . Disposal alternatives <br /> will be evaluated at a later date based on laboratory results of rinseate . <br /> 3 . 2 . CPT GROUNDWATER SAMPLING <br /> -J Grab groundwater samples will be collected using a HydroPunch sample tool that will be <br /> J pushed into specified zones , then withdrawn approximately three feet to expose an inlet <br /> screen . The interior of the sampling tool fills with water and a 1 -inch outer diameter <br /> stainless steel bailer will be lowered and utilized to extract a groundwater sample . All <br /> rinseate generated during drilling activities will be containerized in properly labeled <br /> UDOT-approved 55-gallon drums , and stored on-site in an area lacking public access . <br /> Following sample collection , samples will be transferred to laboratory-supplied <br /> containers , properly labeled and placed in a chilled container to be transported under <br /> � ] chain of custody to a CDPH -certified laboratory for analysis . <br /> r 3 . 3 . BORING ABANDONMENT <br /> Following borehole advancement, Portland cement (grout mix) will be utilized to backfill <br /> each borehole utilizing a tremie pipe . The SJCEHD will be given the opportunity to <br /> inspect the grout mix prior to backfilling activities . <br /> L . <br /> i <br /> Advanced GeoEnvironmental Inc. <br /> i <br />
