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 29-4M 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 <br />Magnesium <br />Conductivity at 250 Beryllium <br />Manganese <br />Temperature Bicarbonate <br />Nickel <br />Boron <br />Nitrogen -Nitrate <br />Cadmium <br />Nitrogen -Ammonia <br />Calcium <br />Potassium <br />Carbonate <br />Selenium <br />Chloride <br />Sodium <br />Chromium (trivalent) Sulfate <br />Copper Total Dissolved Solids <br />Fluoride Sodium Adsorption Ratio <br />Iron Zinc <br />Lead <br />' 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, 2015 to September 30, 2016) are <br />summarized and compared with the data from the baseline hydrology inventory.
