Table 2 <br /> Transit Mix Daniels Pit Wash Fines Settling Pond Relocation <br /> Maximum Estimated Ground Water Elevation Rise After 1 Year of Operation <br /> Water Level Rise(feet) <br /> Location T=5,000 gpd/ft T=9,000 gpd/ft <br /> Edge of Proposed Pond 16.0 11.1 <br /> Schlage Extraction Wells 10.8 8.1 <br /> 1,000 feet from Proposed Pond 4.5 4.2 <br /> Notes: <br /> 1) Ground water elevation rise estimated using superposition multi-well Theis analysis and the following <br /> aquifer characteristics: <br /> Storage Coefficient: 0.2 <br /> Transmissivity: 5,000 gpd/ft and 9,000 gpd/ft <br /> Saturated Thickness: 20 feet <br /> Pumping Duration: 365 days <br /> 2) Transmissivity of 5,000 gpd/ft estimated from Schlage Lock Table 2.7 Local Transmissivity Estimates <br /> near Interception and Injection Wells,at sites located in northwest Little Johnson Reservoir. <br /> 3) Transmissivity of 9,000 gpd/ft estimated based on USGS Water-Resources Investigations Report 94-4129, <br /> Hydrogeologic characteristics of the alluvial aquifer and adjacent deposits of the Fountain Creek valley, El <br /> Paso County,Colorado,showing a weighted average hydraulic conductivity of 48 ft/d for a cross-section <br /> located slightly east of the proposed location of the new wash fines settling pond and an average saturated <br /> thickness of 25 ft within the footprint of the planned pond location. <br /> 4) Saturated thickness estimated from Brierley borehole tests. <br /> 5) Wells simulated as 9 equidistant wells of 160-foot bore hole radii,for a total pond area of approximately <br /> 21 acres. <br /> 6) Pumping also equally distributed at rates of 35 gpm per well,for a total of 315 gpm. <br /> 7) Schlage extraction wells estimated to be approximately 340 feet south of the proposed pond. <br /> BBA <br /> watcrconsultants BISHOP-BROGDEN ASSOCIATES, INC. <br />
