• Monitoring Stations. The historic summary of hydrologic monitoring <br />sites are identified in Table 3, Parts 1 through 3, while the current <br />summary of hydrologic monitoring sites are identified in Table 3A, Parts <br />1 through 3. A detailed discussion of the monitoring implemented by <br />Empire Energy Corporation is presented in Section 2.04.7, Hydrological <br />Information and Section 2.05 Mining And Reclamation Plan. <br />A more detailed discussion of the regional hydrology rology for both <br />surface and ground water has been included in the permit as Exhibit 7, <br />Regional Hydrology Information. <br />Regional Ground Water Quality <br /> Empire Energy has researched publications from the United States <br /> Geological Survey (USGS), Water Resources Division, to obtain available <br /> information describing ground water quality near the mine site. It was <br /> found that there are 22 USGS ground water sampling sites located close <br />• to the mine. The water samples were collected by the USGS from 21 wells <br /> and one (1) spring from aquifers in the alluvium, the Williams Fork and <br /> Iles Formations, and the Mancos and Lewis Shales. However, there was <br /> not enough information available from the USGS publications to determine <br /> which sandstones in the Williams Fork and Iles Formations produced the <br /> water. Sampling site locations are shown on Figure 2, USGS Sample <br /> Sites. The chemical analyses of water samples colle~=ted at the sites <br /> are presented on Table 5, Specific Conductance and p.~ of Ground Water <br /> Near Mine Site, Table 5, Specific Conductance and pH of Ground Water at <br /> a Distance from the Mine Site. Table 6, Ground Water Quality Data Near <br /> Mine Site, and Table 7, Ground Water Quality Data at a Distance from <br /> Mine Site. Upon review of the tables, it is apparent that not all the <br /> ground water samples were analyzed for chemical constituents. Specific <br /> conductance and pH measurements were taken at approximately 15 sites. <br /> The remaining seven (7) site were sampled and analyzed for total <br /> dissolved solids, pH, iron, and manganese. The sampling sites were <br /> visited by the USGS once, and only one (1) water sample was collected at <br />. each site. Measurement of the spring discharge was not taken at the <br /> time USGS personnel collected the water sample. <br />2.04.5-9 Revis~.d 4/21/88 <br />
