AWES, LLC <br /> construction details of the monitoring wells were not reported in WesTest's summary report but are <br /> identified as one-inch monitoring wells by the operator. Boring logs are presented in Appendix A. <br /> 2.2 Groundwater Level Measurements <br /> All monitoring wells were surveyed to the nearest 0.01 foot for vertical elevation and to the nearest 0.5 <br /> foot for horizontal location. Groundwater level measurements in all wells have been measured by an <br /> electric water level indicator on a monthly basis since September 2015. Raptor will continue to measure <br /> water levels on a monthly basis during dewatering operations. After reclamation groundwater levels will <br /> be measured on a quarterly basis until the mine permit has been withdrawn. <br /> 2.3 Chemical Analyses <br /> Table 1 presents field parameters and laboratory analyses for samples obtained from one well selected as <br /> a compliance monitoring well. Water levels will be measured from all wells on a monthly basis. Five <br /> samples will be obtained from the compliance well on a quarterly basis will be analyzed for the parameters <br /> below to establish a baseline.The compliance well will be sampled annually thereafter. <br /> Table 1—Analytical Parameters <br /> Parameter Analytical Method Units Water Quality Frequency <br /> Standard <br /> Field Parameters <br /> pH Direct 6.5-9 Annual <br /> Measurement s.u. <br /> Specific Conductance Direct US/cm N/A Annual <br /> Measurement <br /> Temperature Direct OF N/A Annual <br /> Measurement <br /> Water Level Direct Ft.
