1 <br /> OBJECTIVE AND SCOPE OF SITE ASSESSMENT <br /> The work performed for this investigation included locating underground utilities, obtaining <br /> permits from the PHSIEHD, drilling and advancing six soil borings to depths of 10 feet to 20 feet, <br /> installing three groundwater monitoring wells in three of the borings, surveying, developing and <br /> sampling the wells, and, submitting selected soil and groundwater samples for laboratory analysis <br /> The purpose of this work was to determine if the soil and groundwater beneath the site has been <br /> impacted by the former USTs <br /> All drillingactivities were performed under the supervision of a Smith Environmental field <br /> P P <br /> geologist All site work was performed in accordance with the field methods and Site Safety and <br /> Health Plan included in Smith Environmental's "Workplan for Site Investigation" (May 26, 1995) <br /> I <br /> FIELD INVESTIGATION <br /> Soil Borings <br /> ' On January 5, 1996, six soil borings (MW-1, MW-2, MW-3, SB-1, SB-2, and SB-3) were <br /> advanced to depths of approximately 10 to 20 feet in locations upgradient and downgradient from <br /> the former USTs and inside the former gasoline UST pit (Figure 2) Borings MW-2 and MW-3 <br /> were located downgradient of the former gasoline UST pit and the former waste oil UST pit, <br /> ' respectively Boring MW-1 was located upgradient of the former gasoline UST pit Borings SB- <br /> 1 1, S13-2 and SB-3 were located inside the former gasoline UST pit The bonngs were advanced <br /> using 8-inch outside diameter hollow stem augers All drilling was performed by Spectrum <br /> Exploration, Inc (Spectrum, C57 #512268) Drill cuttings were placed in 55-gallon drums <br /> approved for hazardous waste storage and stored on site pending laboratory analysis Soil <br /> samples were collected at five foot intervals and field screened with a flame ionization detector <br /> (FID) for evidence of volatile organic compounds (VOCs) FID readings were low, less than 5 0 <br /> parts per million (ppm), in borings MW-1, MW-2, MW-3 and SB-1 However, FID readings <br /> WW5[1"SAas 2 <br /> • <br /> 1 <br /> Sion <br />
