'RF~1993 Annual Hydrology Report (Period 1/1/95 - 12/31/95)
Date: June 6, 1996
Summary report of annual hydrologic monitoring in accordance with Rule 4.05.13(4): water
quality and quantity data obtained from each monitoring site, interpretation of the data, and
identification of mining related impacts to the hydrologic balance.
4 OS 13(41(cl(il Water quality data obtained from each monitoring site:
Reference attached water quality summary tables: Table 5, Permanent Diversion; Table 6,
Refuse Well; and Table 7, Iuppa Well.
4.05.13(4)(c)(ii) Water quantity data obtained from each monitoring site:
Reference attached water well level and flow tables and figures: Table 2, Permanent
Diversion Flows; Table 3, Groundwater Well Levels; Figure 1, Iuppa Well Water Levels;
Figure 2, Refuse Well Water Levels; and Figure 3, Precipitation Summary.
4.05.13(4)(c)(iii) Interpretation of the data and identification of mining related impacts to the
hvdtologic balance:
Groundwater quality:
Quality data from both wells are within range of previous monitoring periods. There are no
indications of impacts to water quality as a result of mining.
Groundwater levels:
Water levels in Iuppa Well is consistent with previous monitoring periods. Water levels in
Refuse Well stopped declining from the 1994 period. The decline, possibly a result of
reclamation activities, has reached equilibrium. There are no negative impacts to water well
levels as a result of mining.
Surface water quality:
Quality data from the single flow event monitored in the Permanent Starkville diversion
indicate that the water quality is improved as compared to previous monitoring results. These
data indicate that there are no negative impacts to the surface water quality as a result of
mining.
