1 <br /> Three ground-water wells are located within a 2 , 000 foot radius of <br /> the subject site (Figure 5) . The well owners, locations, date <br />' drilled and their usages are listed as follows: <br /> Location: Sanguinetti Lane and Mistletoe Ave <br /> Owner: California Water Service <br />' Date Drilled: 1956 <br /> Use: Water Well <br />' Location: 2336 Robbindale <br /> Owner: J. B. Court <br /> Date Drilled: No Date <br /> Use: Water Well <br /> Location: 2605 N. Wilson Way <br /> Owner: Alfred Mayer <br /> Date Drilled: 1966 <br /> Use: Water Well <br />' PROCEDURES <br /> To determine both the extent of the ground-water and the soil <br />' contaminant plumes five borings were advanced in the subject site <br /> between 18 and 21 May 1993 . Three of these borings were completed <br /> as 211 diameter monitoring wells. The borings were advanced with <br /> 6. 75-inch diameter hollow-stem augers and a truck mounted drill <br /> rig. <br /> Borings B4 , B5, and B6 were drilled to a depth of 90 feet. Borings <br />' B6 and B8 were drilled to a depth of 70 feet. Soil samples were <br /> obtained at five foot increments in each boring (Boring Logs) . <br /> Discrete, relatively undisturbed soil samples were obtained from <br /> ahead of the hollow-stem auger drill bit utilizing a split tube <br /> sampler loaded with four pre-cleaned 2 .5 by 6 inch brass tubes. <br />' Upon retrieval of the sampler the ends of the middle brass tube <br /> were immediately covered with teflon tape, capped, and sealed with <br /> duct tape. The samples were labeled and then placed in a container <br /> chilled with dry ice for transport to the laboratory. <br /> The soil samples from borings B4 and B5 were shipped, with chain of <br /> custodies, to Applied Consultants Santa Ana office, VIA Greyhound <br />' Bus Lines. Soil samples from B6, B7, and B8 were transported to <br /> Applied Consultants San Diego office, VIA Applied Consultants <br /> personnel, and then to laboratory. The soil samples remained frozen <br />' with dry ice until reaching the laboratory. <br /> U-HAUL 12701 N WMSON WAY <br /> W&93-M!U-HAUL QM4 (SD5020 2) <br /> 14 JUNE 1993 3 <br />
