V <br /> �A <br /> TC <br /> A S S O C I A T E S I N C . <br /> SCOPE OF WORK <br /> Advancement of Soil Borings <br /> To evaluate the potential presence of impacted soil and groundwater at the site, ATC attempted <br /> to advance a soil boring immediately to the north of the northmost tank of the seperator using a <br /> hand auger. This boring was unable to reach the desired depth due to encountering solid concrete <br /> at approximately 5 feet below ground surface (bgs), suspected to be an extended footing for the <br /> seperator tank. The soil encountered during this attempt appeared clean, with no unusual odors, <br /> but did contain building material debris. A second boring, SB1, was advanced through the <br /> bottom of the northmost seperator tank to a total depth of 8 feet, with a soil sample collected <br /> between 7.5 and 8 feet bgs. Soil encountered in this boring appeared to be clean silt, with no <br /> debris and no unusual odors. Boring locations are shown on Figure 2. <br /> Following soil and groundwater sample collection, the borings were backfilled with native <br /> materials to the ground surface. No drill cuttings were generated. <br /> Sample Analyses <br /> The soil sample collected from the soil boring SB 1 was immediately placed in a cooler with ice <br /> and delivered under chain-of-custody documentation to a State-certified analytical laboratory. <br /> The soil sample was analyzed on an immediate turn-around basis for 59 volatile organic <br /> compounds including gasoline constituents benzene, toluene, ethylbenzene, and xylenes (BTEX); <br /> oxygenate fuel additives including MTBE, 1,2-dibromoethane (EDB); and 1,2-dichloroethane <br /> (1,2-DCA); vinyl chloride, carbon tetrachloride, trichloroethene, and tetrachloroethene ("Pere" as <br /> used in dry-cleaning) by EPA Method 8260B. <br /> RESULTS <br /> Soil Analytical Results <br /> Results of laboratory analyses performed on selected soil samples collected from the soil boring <br /> indicate that none of the 59 volatile organic compounds tested for were present at detectable <br /> levels in the soil beneath the site. A copy of the laboratory analytical report is included in <br /> Attachment 1. <br /> w:\enviromenta1\05257\5406\Sub Inv Rpt.doc 2 <br />
