TATs tcY T.PirPI c <br />Water level data are presented in Appendix B. The table of contents of <br />Appendix B indicates wells with PSCM monitoring requirements (all other <br />wells were required by the old Seneca II Mine permit). Water level <br />reports for data collected since 2006 are presented immediately after <br />the water level hydrograph of all historic data for each respective <br />well. By presenting all historic data, trends related to seasonal and <br />annual variability and possible mining -related impacts are more evident. <br />Table 3 (Summary of Ground Water Monitoring Wells) is presented as a <br />reference for the reader. No monitor wells were completed or abandoned <br />this year. The ground water monitoring program is presented on pages 7- <br />341/342 of the Seneca II PAP and on Table 2.04.7-T9, page 2.04-104 (Vol. <br />1) of the PSCM PAP. Water level measurements obtained in non -flowing <br />wells are taken with a water level indicator, or in the case of a few <br />shallow alluvial wells, directly from a steel tape. Pressure readings <br />(in psi) obtained from flowing wells with pressure gages are multiplied <br />by 2.31 to obtain head in feet. For the sake of brevity, the prefix that <br />precedes all well names will be dropped throughout this report (except <br />in the case of nested wells with a similar number). As an example, Well <br />SCAL46 may be referred to as Well 46. <br />Ground Water Level Summary. <br />This y ar, water levels at all wells were within the'r historic ranges, <br />with t e exceptions of COV23, CW23, SCAL69 and SW19 hich all displayed <br />water evels that were less than the historical ranges. <br />All alluvial wells show distinct seasonal water level fluctuations in <br />response to periods of precipitation recharge or the lack of <br />precipitation. Overburden and coal well water levels display fluctuation <br />in response to precipitation recharge, induced ground water flow to the <br />reclaimed mine pits, and in some cases, changes in reservoir water <br />levels. Spoil well water levels still inicate that only the furthest <br />downslope highwall portions of the spoil exhibit significant amounts of <br />saturation. <br />9 <br />
