more clearly evident. Table 3 (Summary of Ground Water Monitoring <br />Wells) is presented as a reference for the reader. No wells were <br />drilled or abandoned this year. The ground water monitoring program is <br />presented on pages 7-341/342 of the Seneca II PAP. Water level <br />measurements obtained in non-flowing wells are taken with water level <br />indicator, or in the case of a few shallow alluvial wells, directly from <br />a steel tape. Pressure readings (in psi) obtained from flowing wells <br />with pressure gages are multiplied by 2.31 to obtain head in feet. For <br />the sake of brevity, the prefix that precedes all well names will be <br />dropped throughout this report (except in the case of nested wells with <br />a similar number). As an example, Well SCAL46 may be referred to as <br />Well 46. <br /> Ground Water Level Summary. This year, water levels at all wells fell <br /> within their historic ranges, with the following exceptions. Wells <br /> SL042, SW16, SW17, SSP27, SSP62, SSP63 and SSP64 all exhibited their <br /> highest water levels ever this May. Well SOV42 exhibited its highest <br /> water levels ever this September. Wadge Underburden Wells SWU6 and 11 <br /> also co ntinue to exhibit increasing water levels. Wadge Underburden Well <br /> SWU8P1 continues with a long-term decrease in water levels. <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 />only the furthest downslope highwall portions of the spoil exhib_Lt <br />significant amounts of saturation. <br />Ground Water Quality. Ground water samples were collected from sixteen <br />wells on an annual or biannual basis. The parameter list used for all <br />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 />3
