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 no exceptions. <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 seventeen <br />wells on an annual or biannual basis. The parameter lists used for all <br />wells sampled this year are given on Tables 4 and 4A. 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. The PSCM ground water monitoring program may be found on Table <br />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 discussion of water quality will be limited <br />to a description of total dissolved solids (TDS) concentrations. A <br />separate section, Comparison of Ground Water Quality to Water Use <br />Standards, will discuss any samples that exceed water use 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 />explaining the sampling procedure. This is followed by a plot of TDS <br />versus time for the entire period of record. The regression line on this <br />4 <br />
