• Monitoring Well Water Quality <br />Water quality monitoring results are in table form in Appendix B and C. Generally, quality <br />parameters at all groundwater monitoring wells were within historic ranges. No significant <br />abnormalities were noted during 1997-98. <br />Surface Water Monitoring Results <br />Table 1 in Appendix A, shows the approved Surface Water monitoring program for the New <br />Horizon Mine. This includes seven (7) NPDES discharge points. <br />Surface Water Monitoring <br />Appendix B and C document the 1997-98 water year monitoring data including flow rates and lab <br />analysis. The data is shown both in table and graph form. Normal fluctuations in water levels <br />were concurrent with irrigation season and spring runoff. <br />Water quality monitoring results are in table form in Appendix B and C. Generally, quality <br />• parameters at all groundwater monitoring wells were well within historic ranges. No significant <br />abnormalities were noted during the 1997-98 water year. <br />NPDES Discharge Monitoring <br />Appendix B, C and D contains the flow and water quality data for seven (7) NPDES discharge <br />points. At New Horizon 1, only NPDES 001 discharged while ponds 002, 003, 004, 005, and <br />006 an evoporation rate equal or greater than inflow rates. At New Horizon 2 Mine NPDES 007 <br />(SW-N102) discharged during the period. All NPDES discharges were within parameter <br />limitations for water quality and quantity. <br />Whole Toxicity Testing (WET) <br />Whole Toxicity Testing was conducted on water discharged front Pond 007 on a quarterly basis <br />and from Pond 001 on an annual basis. All test during this period passed. The results are shown <br />in Appendix D. <br />Probable Hydrologic Consequences <br />There were no extra-ordinary changes in the hydrological system at the New Horizon Mine area <br />during this year. <br />• <br />
