SECTION 5 <br /> CONCLUSIONS AND FIGURES <br /> During this site investigation, three (3) soil borings were drilledto 25 feet bgs and <br /> each were converted to monitoring wells designed to monitor the free water table. Water <br /> levels were measured and a groundwater gradient established. Soil samples were taken <br /> from each boring and one sample p per well was analyzed for TPH and BT`FX. Water <br /> samples were taken from each well and were also analyzed for TPH and BTBX. No <br /> floating product was found in any of the wells. <br /> A summary of findings from this site investigation are as follows: <br /> Groundwater flow direction at the site is to the northeast(Figure 6). <br /> • Samples from Well MW-2, downgradient of the pumps islands, contain the <br /> ;z ltd following concentrations: 760 ppb (water) benzene; 2000 ppb (soil) and 40 ppb <br /> L` (water) ethylbenzene; 50 ppb (water) toluene; 5000 ppb (soil) and 110 ppb(water) <br /> xylenes; and 1500 ppm (soil)TPH. <br /> p <br /> • Soil and groundwater samples from Wells MW-1 and MW-3 showed non- <br /> detectable limits of TPH and BTEX, except for 12 <br /> P pprn TPH in soilfrom Well <br /> -f; MW-1. <br /> f� Na free product was detected in any of the monitoring wells. <br /> a <br /> 5-1 <br /> i 175-07.85 484191 <br />
