Ground Water <br /> Water Levels. Water level data are presented in Appendix B. Water <br />level reports for data collected since 2004 are presented immediately <br />after the water level hydrograph of all historic data for each <br /> 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 wells were drilled or <br />abandoned this year. However, Well SFAL72 (a GWPOC) was added to the <br />monitoring program. The ground water monitoring program is presented on <br />pages 7-341/342 of the Seneca II PAP. Water level measurements obtained <br /> in non-flowing wells are taken with water level indicator, or in the <br />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. Wadge <br />Underburden Wells SWU6 and 11 continue to exhibit increasing water <br />levels. Wadge Underburden Well SWU8P1 continues with a long-term <br />decrease in water levels. Lower Grassy Creek Well 70 displayed its <br />lowest water level on record in September. Beaver dams (or lack <br />thereof) affect ground water levels in this stretch. <br />All alluvial wells are showing distinct seasonal water level <br />fluctuations in response to periods of precipitation recharge or the <br />lack of precipitation. Overburden and coal well water levels are <br />fluctuating in response to the precipitation recharge, induced ground <br />water flow to the reclaimed mine pits, and in some cases, changes in <br />reservoir water levels. Spoil well water levels still indicate that <br />3
