runoff recharge event. This year, all wells displayed water levels that <br />fell within their historic ranges. <br />- Wadge Coal. Five wells monitor this seam. Wells 16 and 17 are in <br />hydraulic communication with the Wadge Impoundment (NPDES 002 Pond) as <br />indicated by their water level changes in response to changes in the <br />pond's water level. Well 19 is a flowing well fitted with a pressure <br />gage that normally exhibits its highest pressure values in the fall. <br />Well SW41 exhibits the same typical seasonal variation as noted for the <br />alluvium. Well 42 exhibits very little seasonal variation and a <br />decreasing water level trend since 1997. All of these wells this year <br />displayed water levels within their historic ranges. <br />- Wolf Creek Overburden/Wadge Underburden. Four wells monitor the Wadge <br />Underburden in the Wadge Coal mining area. Well 6 exhibits the same <br />typical seasonal variation as noted for the alluvium and, up until 1997, <br />exhibited an increasing water level trend. Water levels at this well <br />have recently dropped, but continue to fall within its historic range. <br />Well 8P1 continues with a long-term decreasing water level trend. A <br />casing obstruction in Well 8 (adjacent observation well to Well 8P1), <br />which first occurred in September 1996, prevents measurements of water <br />levels. Well 11 (another flowing well fitted with a pressure gage) <br />continues with a long-term increasing water level trend. One well <br />monitors the Wolf Creek Overburden in the Wolf Creek Coal mining area. <br />Well 7 exhibits typical seasonal variability with water levels measured <br />within its historic range. <br />- Wolf Creek Coal. The one well that monitors the Wolf Creek Coal seam, <br />Well 10, exhibits this year water levels within its historic range, and <br />with same typical seasonal variability as previously defined. <br />- Spoils. Three wells; 22, 23, and 24; are completed in the upper <br />region of spoils above the Wadge Impoundment, which is generally <br />unsaturated. The 3.8 feet of saturation previously observed in Well 22 <br />is most likely incorrect since adjacent Wells 23 and 24 are normally <br />dry. The suspect water levels in Well 22 may be a result of water <br /> <br /> <br />• <br />4 <br />
