' HARGIS+ASSOCIATES, INC. • <br /> 1 <br /> ' Timothy J. Verhagen, Esq. <br /> July 16, 1993 <br /> Page 2 <br /> 1 .0 WATER LEVEL MONITORING <br /> ' Water levels were measured in piezometers and shallow zone monitor wells <br /> on April 26, 1993 (Table 3) . Water levels were measured in all wells, including <br /> those measured on April 26, 1993, except known dry wells and obstructed wells on <br /> ' April 27, 1993. <br /> Reclamation wellfield wells were pumping when water levels were measured <br /> on April 27, 1993, with the exception of intermediate zone reclamation well I-8 <br /> ' which was measured on May 1, 1993 (Table 3) . The water level elevation in <br /> 100-foot sand reclamation well I-1 (MW-3) was approximately -65.7 feet mean sea <br /> level (msl ) (Figure 2) . Water level elevations in intermediate zone reclamation <br /> wells ranged from approximately -48.7 feet msl in reclamation well I-8 to <br /> approximately -80. 1 feet msl in reclamation well I-10 (Figure 3) . Reclamation <br /> well I-8 is located in the MCTC facility north yard. Reclamation well I-10 is <br /> located on Washington Street between Coolidge Avenue and Carrol Avenue. The <br /> ' water level elevation in reclamation well D-1 was approximately -80.2 feet msl <br /> (Figure 4) . A water level was not measured in reclamation well D-2 because <br /> access was obstructed. Reclamation well D-1 is located in the MCTC facility <br /> ' south yard. Reclamation well D-2 is located on Sinclair Avenue south of Horner <br /> Avenue. <br /> ' 1 . 1 Shallow Zone <br /> On April 26, 1993, 6 of 7 shallow zone piezometers and 21 of 29 shallow <br /> ' zone monitor wells and nonpumping reclamation wells were dry (Table 3) . Water <br /> levels were remeasured in all shallow zone wells except known dry wells on <br /> April 27, 1993. <br /> ' The water level elevation in piezometer P-224 was approximately 3.0 feet <br /> msl . Piezometer P-224 is located in the northwestern corner of the MCTC north <br /> yard. The water level in piezometer P-224 may be influenced by infiltration of <br /> surface water, and therefore may not represent the actual groundwater conditions. <br /> Water level elevations in 8 of 29 shallow zone monitor wells and nonpumping <br /> ' reclamation wells ranged from approximately -37.7 feet msl in monitor well MW-103 <br /> to -53.6 feet msl in monitor well MW-9. The water level in monitor well MW-103 <br /> represents residual water that is present in the blank casing below the screened <br /> interval , and therefore does not represent actual groundwater conditions. <br /> ' Monitor well MW-103 is located at the southwest corner of the MCTC facility north <br /> yard. Monitor well MW-9 is located in the southwest corner of the MCTC south <br /> yard. <br /> 1 <br />
