found dry in 2006. All other wells recorded water levels and samples were taken. <br />These samples were tested, at a minimum, for the constituents as required by Exhibit <br />25, part III (C) (5.) <br />Water Quantity and Quality <br />Review of the 2005 and 2006 data and the historic data for surface and ground water <br />indicates no evidence of any significant or unpredicted impact to water quantity in the <br />surface and ground water systems. Some decline in water level in the ground water <br />system is evident in past data, likely due to underground mining and subsidence. <br />Impacts are likely transient and temporary and are locally of no consequence due to the <br />lack of use in the general area. At this time, well MW-NW remains dry and is not <br />recording the flooding of the workings at this time. It could be that the water has yet to <br />reach the elevation of the screened interval of this well. Continued monitoring is <br />necessary to validate the prediction that mine flooding will eventually result in recovery <br />of the local ground water level. <br />Water quality sampling data indicate no significant changes in water quality of the <br />surface and ground water in the mine permit area. Inflow to the workings acts as a <br />pumping well; therefore, ground water flow is from the perched aquifers surrounding the <br />mined area toward the mine workings. Until water is measured in MW-NW (completed <br />in the mine workings), no conclusion regarding ground water quality can be made. <br />Continued monitoring in accordance with the approved plan may provide more definitive <br />information in the future. <br />The mine is in compliance with the hydrologic monitoring requirements and with the <br />predictions made in the permit application regarding impacts to the hydrologic regime, <br />to the extent that the current data can be interpreted. This concludes the Division's <br />review. If you have any questions, please call me. <br />Since ely, <br />a~~~-_ <br />Kent Gorham <br />Environmental Protection Specialist II <br />
