sump recirculation ceased. R:00184 -84. Similarly, the drinking water quality <br />standard for molybdenum is 0.035 mg /L. R:00096. The level of molybdenum in <br />Ralston Creek has consistently exceeded this standard since 2001. R:00140. <br />As stated above, after mining ceased, Cotter allowed the Mine to fill with <br />water, creating a "mine pool ". The Mine started filling with water in 2000, <br />eventually rising to a level of about 24 feet below the Steve adit, which is above <br />the elevation of Ralston Creek. R:00032, 00044, 00071, Table 8 -13 at 00074, <br />00077, 00872. In 2007, the water level of the mine pool was the equivalent to <br />the elevation of Ralston Creek. R:00077. In 2009, the mine pool level increased <br />to the level of the SW -B <br />testified that expecting water in the mine pool to migrate in the direction of the <br />hydraulic gradient toward Ralston Creek is an application of basic ground water <br />hydrology and scientific <br />The mine pool contains an estimated 144 million gallons of water with an <br />estimated 42,000 pounds of uranium dissolved in that pool and is perched 500 <br />feet above and less than two miles away from Ralston Reservoir. R:00044, <br />00875, 00882, 00889, 01 <br />IS surface water station. R:00077. The Division <br />ommon sense. R:01002. <br />14 -1015. The mine pool has concentrations in excess of <br />applicable standards of total dissolved solids, uranium, radium, molybdenum, <br />sulfate, antimony, arsenic, iron, manganese, and thallium. R:00044, 00130, <br />00873 -874, 00884. In 2009, the uranium concentration in the mine pool was <br />around 35 mg /L, more than 1,000 times above the state drinking water quality <br />18 <br />
