typical of previously mentioned monitoring wells. Water levels observed • <br />this year for all of these wells fell within their historic ranges. <br />Well WDAL11, located immediately above the NPDES 005 Pond, is normally <br />dry. We 11 WSAL12 is located next to the lower Sage Creek flume site (SW- <br />S2W-FG4). We11 WSAL13 is located on the northern tributary to Sage Creek <br />below the NPDES 009 Pond. Well WSAL14 is located on the southern <br />tributary to Sage Creek below the NPDES 015 Pond. Most of these wells <br />exhibit typical seasonal variations. Water levels observed this year for <br />most of these wells fell within their historic ranges- Well WSAL13 <br />exhibited the lowest water level on record this year. <br />- Wadge Overburden. Most of the five current Wadge overburden wells <br />monitored normally exhibit seasonal variations typical of the overburden <br />aquifer (i.e., shallow in the spring or summer, deepening in the fall). <br />Wells WOV14, 16, and 17 have all exhibited an increase in water levels <br />since 1996. Well WOV18 had exhibited a decrease in water levels in 1998 <br />to 2000, but they are now slowly increasing. Water levels observed this . <br />year at Wells WOV16, 17 and 18 all fell within their historic ranges. <br />Well WOV14 exhibited the highest water levels on record this year. We11 <br />WOV25 was drilled in September 2004. <br />- Wadge Coal. The six current Wadge coal wells monitored normally <br />exhibit the same typical seasonal variations as the previous aquifers <br />discussed. Due to low aquifer transmissivities (range 0.07 to 0.36 <br />ft2/day), water sampling may mask normal water level fluctuations. <br />Wells WW14 and 17 have exhibited an overall increase in water levels <br />since 1998. Well WW18 has displayed a decrease in water levels since <br />1998. Water levels observed this year at Well WW18 were the lowest on <br />record. Water levels at We11s WW3, 14 and 17 fell within their historic <br />ranges. Well WW16 has been dry since August 2004. Well WW25 was drilled <br />in September 2004. <br />- Sage Creek Overburden. Well WSOV25 monitors this stratum in the south <br />area. This well was drilled in September 2004. • <br />4 <br />
