EVALUATION OF POTENTIAL WELL IMPACTS <br />FROM THE PROPOSED <br />NIX PROPERTY SAND AND GRAVEL OPERATION <br />1.0 INTRODUCTION/PURPOSE <br />This report presents the results of an evaluation of the potential effects of aggregate mining at the <br />proposed Nix Sand and Gravel Operation (Nix property) on local groundwater conditions and <br />nearby water supply wells. This water resources evaluation was conducted based on review of <br />existing information and collection of additional data as necessary to assess the effects of the <br />proposed mining operation. <br />For this investigation, Wright Water Engineers, Inc. (WWE) was asked to evaluate the potential <br />impacts from various extraction alternatives including both wet and dry mining. While dry <br />mining is advantageous, concern from local landowners and WWE's initial evaluation of this <br />alternative led Owens Brothers Concrete Company (Owens) to the decision to use wet mining <br />methods to develop the resource. As a result, the evaluation contained in this report focuses on <br />the potential impacts to neighboring groundwater supply wells from the proposed wet mining of <br />the Nix property. A sepazate report has been prepazed by WWE to address the potential impacts <br />to wetlands on the neighboring Sage Hill Farm. <br />2.0 STUDY AREA DESCRIPTION <br />The Nix property is located in the E''/z and S''/z of the SW'/. of Section 28, T3N, R67W in Weld <br />County, Colorado as depicted on Figure 1. The site consists of approximately 320 acres of <br />irrigated agricultural land. <br />The Last Chance Ditch flows in a northeasterly direction immediately to the west of the Nix <br />property. Numerous laterals from the ditch traverse agricultural fields azound the property. The <br />Hill Side Ditch and several laterals serve the Sage Hill Farm immediately south of the Nix <br />property. <br />011-074.000 Wright Water Engineers, Inc. Page i <br />November 2001 <br />
