been previously developed, a total of approximately 15 gallons of water were purged from MW- <br /> 2. <br />' MW-3 was locked and capped but the vault box bolts were missing. Ms Aguiar qualitatively <br /> observed an immiscible layer on MW-3 of approximately 118-inches. She measured the depth <br /> I to water at 48 70 feet (TOC) and total depth at 60 40 feet (bgs). An attempt was made to <br /> remove just the product layer; however, due to the thinness of the layer, the attempt was <br /> abandoned and the well was surged and purged as with the previous wells. Initially removed <br /> water was relatively free of fines Because it was apparent that MW-3 had been previously <br /> developed, a total of approximately 11 gallons of water were purged from MW-3 <br /> Groundwater Sam lin <br /> On 7 February 1994, Ms. Aguiar and I measured the depth to an immiscible layer (where <br /> present) and depth to groundwater using the MMC Oil/Water interface probe. A disposable <br /> bailer was used to qualitatively check for the presence of an immiscible layer not measured by <br /> the probe and purge those wells in which a "product" layer was not observed The <br /> measurements are summarized on Table 1. <br /> TABLE 1 <br /> Groundwater Measurements <br /> Location Date Depth Depth TOC elevation Groundwater <br /> (IL) (Water) Elevation <br /> MW-1 217194 NM 47.91 53.43 5.52 <br /> MW-2 217/94 NM 48.50 54.03 5.53 <br /> MW-3 <br /> 217/94 47.59 47.62 53.04 5.40* <br /> Notes: <br />' IL Immiscible Layer <br /> NM Not Measured <br /> * Corrected using 0.8 relative density multiplier and two significant digits <br /> After collecting the above measurements, MW-1 and MW-2 were purged and sampled. Each <br /> well was purged a minimum of three well volumes with a disposable bailer. In addition, pH, <br />' temperature, and conductivity were measured using a calibrated Hydac meter. Because the pH <br /> probe failed, only temperature and conductivity were used as indicators of sufficient purging. <br /> Care was taken to ensure that the bailers were lowered slowly into the water to reduce <br /> volatilization Approximately 10 and 24 gallons were purged from MW-1 and MW-2 <br /> 4 I, <br />
