2011 AHR McClane & Munger Canyon Mines Page 7 <br />The water contained in the alluvium is virtually unusable. Field water sampling <br />has shown that the conductivity of the groundwater is extremely high (3,000 to <br />100,000). <br />Data gathered for SW -1 and GW -3 are presented in the Tables N -1 through N -7 <br />in Appendix N. The Division's 1987 Material Damage guidelines require any <br />measured salinity values over 1,000 umhos /cm be reported as 'suspect' values. <br />Since baseline values for SW -1 and GW -3 far exceed the Division's 'suspect' <br />levels, the Operator compiled data in order to demonstrate mine discharge does <br />not add salinity to the already high values, rather, lowers the salinity in SWA and <br />GW -3 during the irrigation season. By improving the salinity of the waters in <br />East Salt Creek and the East Salt Creek alluvium, downstream farmers will not <br />suffer loss of production due to the addition of mine discharge. <br />
