analyzed during the 1996 -1997 water year. Appendix I of the Thirteenth Annual Hydrology <br />Report provides the analytical results. Monitoring hole 32 -7M was sampled prior to being <br />mined out in 2001 and 30 -8M before it had a chance to drain after being completely mined <br />around in late 2006. Data is provided in Appendix C of the Seventeenth Annual Hydrology <br />Report for 32 -7M and the Twenty Third Annual Hydrology Report, for 30 -8M. The final <br />sampling for monitoring hole 294M was conducted in September 2012 with the results <br />included in the Twenty Eighth Annual Hydrology Report. <br />TABLE 2 -1 <br />ALLUVIAL MONITORING HOLE WATER QUALITY PARAMETERS' <br />FIELD MEASUREMENTS LABORATORY ANALYSIS* <br />pH Arsenic Magnesium <br />Conductivity at 250 Beryllium Manganese <br />Temperature Bicarbonate Nickel <br />Boron Nitrogen- Nitrate <br />Cadmium Nitrogen- Ammonia <br />Calcium <br />Potassium <br />Carbonate <br />Selenium <br />Chloride <br />Sodium <br />Chromium (trivalent) <br />Sulfate <br />Copper Total Dissolved Solids <br />Fluoride Sodium Adsorption Ratio <br />Iron Zinc <br />Lead <br />1 Groundwater holes in Leases C -8424 and C -8425 were sampled from the middle facie zone and <br />analyzed for these parameters prior to entering those leases, and will be sampled and analyzed <br />again prior to the wells being mined out or before bond release. <br />* Dissolved metals analyses for alluvial and bedrock groundwater <br />2.2 Summary and Analysis of Deserado Mine Hydrology Data <br />Data collected during this water year (October 1, 2013 to September 30, 2014) are <br />summarized and compared with the data from the baseline hydrology inventory.
