Revised 11/15/81 <br /> 2.04.7 Hydrology Description <br /> Groundwater Information <br /> A detailed investigation of the groundwater hydrology for the permit <br /> area and adjacent area of the Maxwell Mine has been conducted for CF&I <br /> Steel Corporation by Water, Waste, and Land, Limited. This report <br /> discusses the location, quality, and quantity of water in the subsurface <br /> of the permit area in detail , is shown in Exhibit 6, Hydrology and <br /> Geology Information. This investigation indicates that very little <br /> groundwater is present in the area which the Maxwell Mine operation is <br /> located. Local drinking water supplies for isolated residents of the <br /> area comes primarily from alluvial valley sources Isolated higher <br /> production wells which supply irrigation water are also located in the <br /> alluvium. Table 7, State Engineer' s Record of Water Wells, shows the <br /> wells which are located within one mile of the Maxwell Mine and their <br /> associated owners, permit numbers and yields. The locations of these <br /> wells are shown on the Regional Hydrology Map (Map 8). A listing of <br /> each individual well , its owner, use, and other pertinent information is <br /> shown in Exhibit 8, Water Well Information. Quality of the subsurface <br /> water has been determined at numerous locations shown on the Regional <br /> Hydrology Map (Map 8). Analyses of the groundwater at these locations <br /> are shown in Exhibit 9, Water Quality Analysis. <br /> Surface Water Information <br /> The surface water quality and quantity information has been developed <br /> through a study by Water, Waste, and Land, Limited for CF&I Steel <br /> Corporation. The report of the quality and quantity of water associated <br /> with the permit and adjacent areas to the Maxwell Mine is found in <br /> Exhibit 6, Hydrology and Geology Information. In addition, water <br /> quality analyses are shown in Exhibit 9, Water Quality Analysis. All <br /> surface waters in the Maxwell permit area and adjacent area are shown on <br /> the Regional Hydrology Map (Map 8). Discharges of surface water at the <br /> Maxwell Mine are shown on the Mine Hydrology Map (Map 9) . Quality of <br /> water associated with both mine discharges and existing surface water is <br /> shown in Exhibit 9, Water Quality Analysis. <br /> 2.04-8 <br />
