Wedge Coal. Five wells monitor this seam. Wells 16 and 17 are in hydraulic communication with the Wedge Impoundment (NPDES 002 Pond) because their water le vels change in response • to a change in the pond's water level. Well 19 is a flowing well fitted with a pressure gage that exhibits its highest pressure values in the fall. Well SW41 exhibits the same typical seasonal variation as noted fox the alluvium. Well SW42 exhibits an increasing water level trend at its adjacent backfilled mine pit continues to rasa tore te. Wolf Creek Overburden/Wedge Underburden. Four wells monitor the Wadga Underburden in the Wedge Coal mining area. Well 6 exhibits typical seasonal variation (as defined in the preceding Alluvium discussion) and continues to exhibit an increasing water level trend. Well BP1 continues with a long-term decreasing water level trend. A casing obstruction in Well 8 (adjacent observation well to Well BP1), which first occurred in September 1996, prevents measurements of water levels. Well 11 continues with a long-term increasing water level trend. One well monitors the Wolf Creek Overburden in the Wolf Creek Coal mining area. Well 7 exhibits typical seasonal variability. Wolf Creek Coal. ~ One of the two wells (Well 10) that monitor the Wolf Creek Coal seam exhibited the acme typical seasonal variability as previously defined. Well 15 has exhibited i n the pant four years the lowest water levels on record. This is due to dewatering from the adjacent mining pit. This well was abandoned in March 1998 in preparation for the highwall reduction that rae to occur later in the year For final reclamation in the area. Spoils. Three wells;'~22, 23, and 24; era completed in the upper region of epoila above the Wedge Impoundment, which is generally unsaturated. The 3.8 feet of saturation observed rn Well 22 is most likely incorrect since adjacent wells 23 and 24 are normally dry. The suspect water levels in Well 22 may be a result of watez trapped in the borehole (perhaps by a boulder in the epoi la that the borehole does not completely penetrate). However, this well became dry in August 1998. Well 23 eometimea shows water in late February, March, and April as snow mel to quickly off this westerly-facing elope, al though it has been dry since 1985. Well 24 has been dry For the entire period of record. Three wells; 25, 26, and 27; are situated in the lower region of spoils above the Wadqe Impoundment. All three of these wells were outfitted with continuous recorders operated by the V.S. Geologrcal Survey (USGS) until the end of 1983. well 25, the highest upgradient of these three wells on the spoils slope, indicated an abaenca of rechazge in 4
