Current Water Monitoring <br />The current water monitoring plan requires water levels and water quality sampling of ground <br />water resources in the vicinity of the mine and mine workings. Three alluvial wells are <br />monitored twice annually for water level and field parameters and sampled annually for water <br />quality. These three alluvial wells are not in the immediate vicinity of the area of interest. <br />Four bedrock wells, one south and east of the mine workings and three north of the mine <br />workings, are monitored annually for water level. Two former ventilation shaft locations <br />(Jeffrey intake called GEM-1 and 3rd North intake called GEM-2) are used to monitor water <br />level in the flooding mine workings twice each year and annually the water is tested for <br />generally water quality. The NW-1 vent shaft, called GEM-3, is measured twice annually for <br />water level. Water sampling is not conducted at this location due to plumbing issues at the <br />surface. Water level in the flooded workings stood at 6775 feet AMSL and data trends <br />indicate the mine is flooding at a rate of about 1.3 feet per month. Cross sections and water <br />level plots are included in Appendix A. <br />TABLE 1.2-7 HYDROLOGY MONITORING REQUIREMENTS GOLDEN EAGLE <br />Site Water Level Measurement A^nual List <br />Groundwater Sites: <br />PAW-5 S S A <br />PAW-6 S S A <br />CCAW-I S S A <br />SF-2 (Overburden} A ~ ' <br />NM-22 (Overburden) A <br />NM-20 (Overburden) A <br />NM-21 (Coal) _ A <br />GEM-1 (Mine workings) S A A <br />GEM-2 (Mine workings) S A A <br />GEM-3 (Mine workings) 5 <br />KEY: <br />S =Semi-Annual (May antl November) <br />A =Annually (November) <br />' =See Table 1.2-2 for parameters included in each suite <br />TABLE 1.2-2 WATER QUALITY PARAMETER SAMPLE SUITES GOLDEN EAGLE <br />MINE <br />Field Measurements Annual list <br />Water Level (Depth) Sodium Absorption Ration (SAR) <br />pH (S.UJ Total Dissolved Solids (TDS) (mgp) <br />Conductivity (µmhos/cm) Carbonate (mg/I) <br />Temperature (°C) Bicarhonate (mg/1) <br /> Sulfate (mg/l ) <br /> Manganese, Total(mg/I) - <br /> hfanganese, Dissolved (mg/l) <br /> Calcium (mg/1) <br /> Magnesium (mg/I) <br /> Sodium (mg/I) <br /> Iron, Total (mg/I) - <br /> Iron, Dissolved (mg/I) <br /> Lead (mg/1) <br /> Selenium, Dissolved (mg/1) <br /> Hardness <br />
