alluvial wells, are affected by [he absence or presence of beaver dams rn the adjacent <br />stream. • <br />- Lennox Overburden/Wadge Overburden. The three rails completed rn these formations <br />(Wells SL042, SOV41, and SOV42) exhibit normal seasonal variations, that is, lowest water <br />levels in the fall and rioter, and highest in the late spring/early summer after the <br />spring runoff recharge event. This year, all walla displayed water levels that fell <br />xi thin their historic ranges. <br />- Wadge Coal. Five wells monitor this seam. Wells 16 and 17 are in hydraulic <br />communication with [he Wadge Impoundment (NPDES 002 Pond) as indicated by their Mater <br />level changes in response Co changes in the pond's water level. Well 19 is a flowing well <br />fitted with a pressure gage that exhibits its highest pressure values in the fall. Wells <br />SW41 and SW42 exhibits the same typical seasonal vaziation as noted fox the alluvium. All <br />of these wells displayed, this year, water levels xi thin their historic ranges. <br />- Wolf Creak Overburden/Wadge Underburden. Four wells monitor the Wadge Underburden in <br />the Wadge Coal mining area. Well 6 exhibits the same typical seasonal variation ae noted • <br />for the alluvium and, up until 1997, exhibited an increasing water level trend. Water <br />levels at this well have recently dropped, but continue to fall within its historic range. <br />Nall SP1 continues with a long-term deereaaing water level trend. A casing obstruction in <br />Well a (adjacent observation well to Well BP1), which first occurred in September 199fi, <br />prevents measurements of water levels. Well 11 (another flowing well fitted with a <br />pressure gaga) continues with a long-term increasing rater level trend. One well monitors <br />the wolf Creek Overburden in Ue Wolf Creek Coal mining area. Well 7 exhibits typical <br />seasonal variability wr th water levels measured within its historic range. <br />- Wolf Creek Coal. The one well that monitors the Wolf Creek Coal seam, Well 10, exhibits <br />water levels within its historic range, and with same typical seasonal variability as <br />previously defined. <br />- Spoils. Three wells; 22, 23, and 24; axe completed in the upper region of spoils above <br />the watlge Impoundment, which is generally unsatura red. The 3.B feet of saturation <br />previously observed in Well 22 is most likely incorrect since adjacent Wells 23 and 24 are <br />normally dry. The suspect water levels in Well 22 may 6e a result of water trapped in the • <br />borehole (perhaps by a boulder in the spoils that the borehole does not completely <br />4 <br />
