West Elk Mine 2016 Surface Water and Groundwater Quantity and Quality Data Summary 9
Table 5. Summary of the Spring and Seep Monitoring Program (Continued)
Shaded cells indicate spring sites that were not monitored in WY 2016.
SW mine panels area — southwest B -seam longwall panels; SE mine panels area — southeast B -seam longwall panels
Box Canyon mine panels area — Box Canyon B -seam longwall panels; W. Flatiron mine panels area — West Flatiron B -seam longwall panels
Jumbo Mountain mine panels area — Jumbo Mountain B -seam longwall panels
SOD mine panels area — South of the Divide E -seam longwall panels
1) For sites with more than 5 years of data, lab parameters include TSS, TDS, EC, pH, and Fe (dissolved & total).
2) For sites with 5 or less years of data, see Table 2
3) Spring E14-1 was covered by well pad construction activity in WY 2006; therefore it was not monitored in WY 2007 or subsequent years.
