2016 Recommended Modifications to the West Elk Mine Hydrologic Monitoring Network <br />2.0 SPRING AND SEEP MONITORING NETWORK SUMMARY <br />The existing MCC WEM hydrologic monitoring network includes a total of 40 spring and seep <br />monitoring sites (Table 1). The locations of the spring and seep monitoring sites are shown on <br />Map 1. Comprehensive data for all of the WEM monitoring sites are summarized in the Annual <br />Hydrology Reports submitted to CDRMS (HydroGeo, 2002 through 2015). It should be noted <br />that several of the monitoring sites have baseline data adapted from the Wright Water Engineers <br />2000 Annual Hydrology Report (WWE, 2001). <br />The routine MCC WEM spring and seep monitoring program required by CDRMS stipulates that <br />spring flow measurements and field water quality data (temperature, electrical conductivity (EC), <br />and pH) be collected three times per year, corresponding to the rising limb, peak flow and low <br />flow sampling rounds at all of the spring monitoring sites (Table 1). In addition, a water quality <br />sample is to be collected at each monitoring site and sent to a certified laboratory for analysis <br />one time per year, during the peak flow sampling round. For sites with more than 5 years of <br />data, lab parameters include total dissolved solids (TDS), and total suspended solids (TSS), EC, <br />pH, and Fe (dissolved & total). <br />August 2016 HydroGeo, Inc. <br />
