i <br />' After water levels were measured, a stainless steel bailer was used to surge and purge MW- <br /> 4. Approximately 8 gallons of water were removed to stabilize temperature, pH and <br /> conductivity (see Table 2) The purge water was stored in a 55-gallon drums on-site. A water <br /> sample was collected using a disposable plastic bailer The sample was collected in three 40- <br /> ml EPA vials and analyzed for TPH as gasoline and BTE&X in accordance with EPA <br /> methods 8015m and 602, respectively <br /> I <br /> f TABLE 1 <br /> RELATIVE GROUNDWATER ELEVATIONS <br />' Depth to Groundwater Groundwater Elevation <br /> Casing <br /> Well No Elevation 10/19/93 1/25/94 10/19/93 1125193 <br />' MW-1 950 3527 3489 -2577 -2539 <br /> MW-2 984 3560 3520 -2576 -2536 <br />' MW-3 9.74 3552 3512 -2578 -2538 <br />' MW-4 9138 35 19 1 3482 -2581 -2544 <br /> All measurements in feet relative to mean sea level <br /> TABLE 2 <br />' GROUNDWATER STABILIZATION DATA <br /> January 25, 1994 <br /> Volume Temperature Conductivity <br />' (gallons) pH (°F) (US/cm x 1000) <br /> MW-4 <br /> 1 0 68 599 261 <br /> 1 71 592 276 <br />' 2 71 615 286 <br />' 3 71 582 273 <br /> 4 71 619 306 <br />' 5 71 628 295 <br /> 6 70 630 303 <br />' 7 71 627 305 <br /> g _ 71 62 7 304 <br /> 5 <br />
