Evaluation of Potential Impacts <br />From The Proposed Nix Property Sand and Gravel Operation <br />On Shallow Groundwater Levels, Water Wells and Wetlands <br />• Memorandum to Paul Gesso from Stan Peters, P.E. dated October 20, 2000, Re: Nix Property <br />Reserve Estimates. <br />• Letter from Stan Peters, P.E. dated December 5, 2000, Re: Nix Property-Aggregate Preserve <br />Estimate for Owens Brothers Concrete Company. <br />• Letter from David J. Cooper dated July 16, 2001, Re: Potential Impacts of Nix Property Sand <br />and Gravel Mine. <br />• Letter from Hydrosphere Resource Consultants dated July 13, 2001, regarding initial <br />comments on potential impacts of Nix property sand and gravel mine. <br />• Letter from Leaf Engineering dated July 13, 2001, regarding Owens Brothers Concrete <br />Company gravel pit-well injury analysis. <br />It should be noted that the letters from Hydrosphere Resource Consultants, Leaf Engineering and <br />David J. Cooper were prepared in response to the potential impacts anticipated from dry mining <br />of the Nix property. They did not address a wet mining alternative, as currently proposed. <br />3.2 Piezometers <br />Seven piezometers (MW-1 through MW-5, MW-7 and MW-10) were installed on the Nix <br />property and adjacent to the wetland on the Sage Hill Farm, south of the Nix property, on August <br />14 and 24, 2001. The piezometers were installed using an auger drill rig and were completed <br />with 2%-inch polyvinyl chloride (PVC) pipe. Most of the piezometers were installed to a depth <br />of approximately 20 feet, with the lowest five feet constructed of slotted casing. Two of these <br />wells were drilled deep enough to encounter bedrock (approximately 50 feet) but were completed <br />to the 20-foot depth. Five piezometers installed by David Cooper (consultant for the Sage Hill <br />Farm) eazlier in the summer were also monitored. These piezometers aze designated as MW-6, <br />MW-8, MW-9, MW-11 and MW-13. Figure 2 shows the locations of the 12 piezometers. <br />' 011-074.000 <br />April 2002 <br />Wright Water Engineers, Inc. <br />Page 5 <br /> <br />
