'Pombo Property <br /> Excavation and Monitoring Well Installation <br /> The following scope of work addresses the recommendations of the SJEHD. <br /> 11 Site Description and History <br /> Specific areas of concern were identified during an Environmental Assessment for <br /> Bright Development, a prospective buyer f the subject property. A portion of the <br /> property at 24100 S. Lammers Road is occupied by a farming facility, which <br /> includes residential dwellings, a barn, quipment sheds and shops. Tractor <br /> storage, repairs, and fueling are conducted in this area, which fronts 11 th Street. <br /> Some pesticide and above ground fuel storage was apparent during the inspection. <br /> Records indicate that the improvements to the parcel started in 1930. The <br /> undeveloped acreage is used for irrigated crops and/or pasture. <br /> Two underground tanks were listed in tf e state records review as in use at the <br /> 24100 S. Lammers Road property but had been removed before 1993. Since the <br /> tanks were farm exempt they may have removed without the normally required <br /> soil sampling. Several above ground tanks are in use at this site. The above <br /> ground tanks are located together centralin the shop and barn area. Historical <br /> photographs show that one of the above ground tanks was located next to the <br /> tractor shop. <br /> On September 16, 1998 M.J. Kloberdanz & Associates drilled 8 Geoprobeig) soil <br /> borings to five feet below groundwater (average depth 15' bgs). A soil sample <br /> was obtained from the capillary fringe in seven of the eight borings. Additional <br /> soil samples were collected from cores with possible contamination. Water <br /> samples were collected from all eight bori igs. <br /> Boring B-1 was drilled in an area of a small pesticide spill identified by the <br /> property owner. Petroleum analysis was included in some of the samples because <br /> of the close proximity to the fuel storage area. Borings B-2, 3, & 4 were drilled <br /> around the above ground fueling area with boring B-3 located at a former <br /> underground tank excavation. Boring -5 was also drilled in the area of a <br /> previously removed underground fuel tank. Boring B-6 was drilled in the Truck <br /> and Tractor wash area and sampled for pesticides and petroleum compounds. <br /> Boring B-7 was drilled in a location where above ground fuel was stored and used <br /> historically. Boring B-8 was drilled in front of the barn at 24124 Lammers Road <br /> where refrigeration equipment is dismantled. Since there was no apparent <br /> spillage or dumping of refrigerants, only groundwater was sampled and analyzed. <br /> 2 <br />
