each respective well. By presenting all historic data, trends related to <br />seasonal and annual variability and possible mining related impacts are <br />more clearly evident. Table 3 (Summary of Ground Water Monitoring Wells) <br />is presented as a reference for the reader. No monitor wells were <br />completed or abandoned this year. The ground water monitoring program is <br />presented on pages 7- 341/342 of the Seneca II PAP and on Table 2.04.7 - <br />T9, page 2.04 -104 (Vol. 1) of the PSCM PAP. Water level measurements <br />obtained in non - flowing wells are taken with water level indicator, or <br />in the case of a few shallow alluvial wells, directly from a steel tape. <br />Pressure readings (in psi) obtained from flowing wells with pressure <br />gages are multiplied by 2.31 to obtain head in feet. For the sake of <br />brevity, the prefix that precedes all well names will be dropped <br />throughout this report (except in the case of nested wells with a <br />similar number). As an example, Well SCAL46 may be referred to as Well <br />46. <br />Ground Water Level Summary. This year, water levels at all wells fell <br />within their historic ranges, with the following exceptions. Lower <br />Grassy Creek Alluvial Well SGAL70 displayed its lowest water levels on <br />record in September of 2010, 2011 and 2012. Beaver dams (or lack <br />thereof) affect ground water levels in this stretch. Cow Camp Alluvial <br />Well SCAL69 displayed it lowest water level ever in September 2012. <br />Overburden Well COV11 (drilled Fall 2010) displayed its highest water <br />levels ever in May thru September 2012. Overburden Well COV23 (drilled <br />2008) displayed its lowest water levels ever in May thru September 2012. <br />Overburden Wells C0V2633 and 2702 (drilled 1983, but not monitored until <br />2008) displayed their lowest water levels ever in September 2012. Water <br />levels dropped 318 and 317 feet, respectively, from their previous <br />readings. <br />Three Wadge Coal wells displayed their lowest water levels in September <br />2012. Well CW23 (drilled 2008) experienced a five foot drop from its <br />previous readings. Wells CW2632 and 2701 experienced 286 and 317 feet <br />drops, respectively, from their previous readings. <br />3 <br />
