EASTSIDE MINE <br />Water Monitoring Program <br />Introduction <br />Baseline surface water monitoring was obtained in September 1983 with a full <br />suite of chemical parameters analyzed. Additional surface and underground <br />hydrologic sampling was analyzed for a full suite of chemical parameters in <br />April 1984. Eastside's hydrologic monitoring program was initiated in July <br />1984. Surface and underground field parameters were measured, and samples <br />for chemical parameters were collected as defined by Stipulation 1 of the <br />Mining and Reclamation Permit, C-84-063, approved January 14, 1985. Due to <br />large reduction in flow, monitoring of the two underground wells and seep <br />was eliminated. After three years of quarterly sampling the full suite of <br />chemical parameters with no significant deviations or variations, the full <br />suite of chemical parameter sampling was reduced from quarterly to semi-~ <br />annual sampling. <br />The present surface sampling points are: 1-Harvey Gap Outlet-Above Mine; <br />2-Harvey Gap Outlet-Below Mine; 3-Seep below Harvey Gap Reservoir. The <br />ground water sampling points are: 1-Mine water as it is discharged from the <br />pipe coming from underground; 2-Geotech well located near the toe of the <br />planned waste disposal pile. <br />The water monitoring program was initiated by Stephen Self, General Manager. <br />Current monitoring is performed by Linda Limbach. Samples for the full <br />suite of chemiial parameters are chipped to ACZ Laboratory in Steamboat <br />Springs, Colorado for analysis. <br />
