�J <br /> 7 <br /> 1 <br /> ti <br /> SECTION 5 <br /> CONCLUSIONS AND FIGURES <br /> { <br /> During this site investigation, three (3) soil borings were drilled to 25 feet bgs and <br /> each were converted to monitoring wells designed to monitor the free water table. Water <br /> is <br /> ' levels were measured and a groundwater gradient established. Soil samples were taken <br />> from each boring and one sample per well was analyzed for TPH and BTEX. Water <br /> r <br /> samples p ere taken from each well and rwere also analyzed for TPH and BTEX No -` <br /> z �floatln roduct-was fn,any of"the wells;�� z <br /> A summary of findings from this site investigation are as follows: <br /> f <br /> Groundwater flow direction at the site is to the northeast(Figure 6). <br /> Samples from Well MW-2, downgradient of the pump islands, contain the <br /> a <br /> following concentrations: 760 ppb (water) benzene; 2000 ppb (soil) and 40 ppb <br /> (water)ethylbenzene; 50 ppb (water) toluene; 6000 ppb (soil)and 110 ppb(water) <br /> xylenes; and 1500 ppm(soil) TPH. <br />' Soil and groundwater samples from Wells MW-1 and MW-3 showed non- <br /> detectable limits of TPH and BTEX, except for 12 ppm TPH in soil from Well <br /> MW-1. <br /> z <br /> • Nd�free product.was_detected in any of the monitoring-wells. <br /> E <br /> F <br /> Y <br /> i <br /> 5-1 <br /> 175-07=R5 4/24191 <br /> 4 <br />
