2.2 CURRENT QUARTER'S FINDINGS <br /> 2.2.1 ZONE A-GROUNDWATER <br /> The groundwater contour map is presented on Figure 4. The monitoring wells are <br /> screened at depths ranging from 30 to 50 feet below ground surface (ft bgs). The depth <br /> to groundwater ranged from 33.17 (MW-6) to 37.23 ft bgs (MW-1). Groundwater <br /> elevations ranged from 86.92 feet above mean sea level (ft MSL) in well MW-15 to <br /> 87.49 ft MSL in well MW-12. The groundwater flow direction was variable. The <br /> calculated hydraulic gradient ranged from 0.001 to 0.005. <br /> Gauging data from well MW-5A appears to have been affected by the absorbent sock; <br /> therefore, this data was not used for contouring. Wells MW-1 and MW-15 are also <br /> constructed in Zone A; however, data from these wells were not used for contouring <br /> because their locations are several hundred feet from the other site wells. The <br /> groundwater elevations for wells MW-1 and MW-15 are presented on Figure 3. <br /> The TPHc and benzene detections are summarized on Figures 3 and 4. <br /> 2.2.2 ZONE B-GROUNDWATER <br /> The groundwater contour map is presented on Figure 5. The monitoring wells are <br /> screened at depths ranging from 105 to 125 ft bgs. The depth to groundwater ranged <br /> from 30.58 (MW-14B) to 35.15 ft bgs (MW-13B). Groundwater elevations ranged from <br /> 85.49 ft MSL in well MW-13B to 87.23 ft MSL in well MW-513. The groundwater flow <br /> direction was generally toward the northwest at a calculated hydraulic gradient of 0.006. <br /> The TPHc and benzene detections are summarized on Figures 3 and 5. <br /> 2.2.3 ZONE C-GROUNDWATER <br /> The groundwater contour map is presented on Figure 6. The monitoring wells are <br /> screened at depths ranging from 160 to 177 ft bgs. The depth to groundwater ranged <br /> from 52.98 (MW-14C) to 55.60 ft bgs (MW-5C). Groundwater elevations ranged from <br /> 64.45 ft MSL in well MW-14C to 66.08 ft MSL in well MW-13C. The groundwater flow <br /> direction was generally toward the east at a calculated hydraulic gradient of 0.004. <br /> 060223(26) 2 CONESTOGA-ROVERS S ASSOCIATES <br />
