Xnowles Gas station <br /> 202/799-5027.02 <br /> s July 21, 1988 <br /> Ir <br /> was labeled with s`oring number, sample number and depth at which <br /> the sample was taken. Selected soil samples were analyzed for <br /> TPH as gasoline and BTEX by modified Environmental Protection <br /> i Agency (EPA) Method 5030/8020/9015; in addition to total lead by <br /> EPA 7420 and EDB. <br /> GROUNDWATER MONITORING <br /> The three existing groundwater monitoring wells were moni- <br /> tored on .Tune 24, 1988 to determine the depth to water and the <br /> presence of free <br /> Ey product if any (see Table 1, Groundwater <br /> Monitoring Data) . In addition, the wells were surveyed to an <br /> fj arbitrary datum for elevation control. The monitoring data was ' <br /> utilized in conjunction with the surveying results to determine <br /> the elevation of groundwater within each of the three monitoring <br /> Wells. The groundwater elevations were then used to determine <br /> + the local groundwater gradient and flow directionbeneath the <br /> site.. <br /> s <br /> f <br /> . <br /> TABLE 1 <br /> GROUNDWATER MONITORING DATA <br /> j) (in feet) <br /> Well Elevation* <br /> Depth to Water* <br /> I Date ID to Grade Water E-levation <br /> t; 6/24/88 MW-1 100.00* 50.88 49. 12 <br /> h <br /> MW-2 100.45 51.29 <br /> 49.16 <br /> E MW-3 99.06 49.89 49.17 <br /> *Arbitrary Datum. <br /> r� <br /> P, 7 <br /> s _ <br /> 1 <br /> 3 �f <br />
