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 Potassium <br /> Carbonate Selenium <br /> Chloride 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, 2020 to September 30, 2021) are <br /> summarized and compared with the data from the baseline hydrology inventory.
