September, as did Wadge Coal Wells 2632 and 2701. However, monitoring of • <br />these four wells began in 2008. <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 only <br />the furthest downslope highwall portions of the spoil exhibit <br />significant amounts of saturation. <br />Ground Water Quality. Ground water samples were collected from twenty <br />two wells on an annual or biannual basis. The parameter list used for <br />all wells sampled this year is given on Table 4. Analyses have been <br />performed by ACZ Laboratory in Steamboat Springs, Colorado since May 31, <br />1983. ACZ Laboratory performs all analyses by EPA or equivalent methods. <br />Samples are delivered the day of collection to the lab in an iced <br />cooler. A complete description of the ground water monitoring program <br />may be found on pages 7-336 to 7-355 of the Seneca II PAP, and is <br />summarized on pages 7-341/342. The PSCM ground water monitoring program <br />may be found on Table 2.04.7-T9, page 2.04-104 (Vol. 1) of the PSCM PAP. <br />The following discussion of the analytical data collected during the <br />reporting period is arranged by strata being monitored and coincides <br />with the format (by aquifer type) in which the analytical data are <br />presented in Appendix C. The table of contents of Appendix C indicates <br />which wells carry PSCM monitoring requirements (all other wells were <br />required by the old Seneca II Mine permit). The discussion of water <br />quality will be limited to a description of total dissolved solids (TDS) <br />concentrations. A separate section, Comparison of Ground Water Quality <br />to Water Use Standards, will discuss any samples that exceed water use <br />standards. <br />Data for each well in this appendix begins with a listing of the water <br />quality data collected during the past two years, followed by remarks <br />4
