FIELD PROCEDURES All field procedures will be overseen by an AGE representative under the supervision of a California Registered Geologist Procedures for the well installation, well development, soil sampling, equipment decontamination and sample shipment procedures are described below 41 CPT SOIL BORINGS Each CPT soil boring will be advanced to a depth of 150 feet bsg utilizing a 25-ton truck-mounted CPT drill rig equipped with 2-inch diameter hollow-stem rods The first soil boring will utilize a hydraulic ram to advance a cone penetrometer to the desired depth Soil parameters such as cone bearing, sleeve friction, friction ration and pore water pressure will be measured as the cone penetrometer is advanced Rinseate generated during drilling activities will be containerized in properly labeled DOT-approved 55-gallon drums, and stored on-site in an area lacking public access Disposal alternatives will be evaluated at a later date based on laboratory results of rinseate A second soil boring will be located no more than three feet from the first CPT boring for soil and ground water sample collection Based on CPT findings, discrete soil samples will be collected at depths in excess of 10 feet bsg and in areas of lithologic variation Soil samples will be collected utilizing a 2-inch diameter piston soil sampling assembly loaded with pre-cleaned brass sleeves Upon soil sample retrieval, a brass sleeve will be removed from the sampler The ends of the brass sleeve will be immediately covered with Teflon or aluminum sheets, sealed with plastic end caps, secured with tape and immediately placed in a chilled container for transportation to a DHS -certified laboratory Each sample sleeve will be labeled with the location, boring designation, depth, time, date and samplees initials • During soil sampling activities, sample duplicates will be monitored for the presence of organic Advanced GcoEnvironmcntal,Inc 1
