Lochhead <br />Ev(smive DrtPCIp <br />Michael B. EonR <br />DIV iSgl1 DlreclOr <br />Susan McCarron has requested Division personnel conduct an investigation into determining <br />whether underground mining activities at the Golden Eagle Mine may be adversely affecting local <br />groundwater systems. She has asked we specifically determine whether a nearby landowner's <br />water well may have recently declined in historic yield and, if so, whether the decline in yield is <br />attributable to the mine's operations. <br />Susan has further asked.thatit be determined whether-one of the mine's airshafts is causing an <br />adverse drdwdoivn of regional aquifers, whether this airshaft, .if found to be causing an adverse <br />drawdown, was constructed in a manner that was expected to minimi~r. impacts to groundwater <br />systems, if the airshaft could be accuse-in the possible yield loss in the landowner's well, and <br />whether the airshaft could be recased or otherwise repaired if it has caused a decline in the well <br />yield. <br />Since Randy Price and Bari3ara Pavlik, our groundwater specialists, are currently both in the <br />midst of several projects that will carry them through to January 1995, and given that Randy will <br />assume Lead Specialist responsibilities for the Basin Resources mines eventually, I believe it <br />makes sense to assign this project to Randy. <br />Susan has asked that the project be initiated as soon as possible. Given that Randy has prior <br />vacation, field work and permitting assignments, I think it would be best if Randy could begin <br />this investigation by January 30, 1995. <br />Thanks, and if you or Randy need further information, please see me. <br />DIHlbjw <br />cc: Joe Dudash <br />Susan McCarron <br />Randy Price <br />M:\055\81 W\DDE.DAB <br />
