Effect of Mining on East Salt Creek Ground Water Regime: <br />The Munger Mine has been sealed and the disturbed areas were graded and seeded in <br />2007. The sediment pond was reclaimed in 2017. There has been no effect on <br />groundwater regime. This is based partly on the size of the operation, as well as the <br />poor quality of the water contained in the aquifer. As stated in the AHR, East Salt Creek <br />is an accurate name. Data for the conductivity of GW -3 is attached, see Chart 6. GW -3 <br />is located in the alluvium of East Salt Creek below Munger. The baseline number for <br />conductivity is 7256 umhos/cm. Nearly all of the data points are below the Baseline, <br />there are however four data points that exceed Baseline for water years 1981, and <br />1982. <br />Conclusion: <br />The operations at the Munger Canyon mine have not had any significant impacts on the <br />quality or quantity of East Salt Creek Hydrologic Regime. There are no adverse impact <br />trends that exist. Generally, water quality sampling has demonstrated that results are <br />highly variable and in-line with the projections in the approved permit document. <br />
