<br />Three wells; 25, 26, and 27~ are situated in the lower region of spoils above <br />the wedge Impoundment. All three of these wells were outfitted with continuous <br />recorders operated by the v.S. Geological Survey (USG9) until the end of 1983. <br />well 25, the highest upgradient o£ these three walla on the spoils elope, <br />indicated as abaeace o£ recharge is 1987, 1988, 1990, 1991, 1998, sad 1999, but <br />exhibited recharge in all other years eiaca 1983. Well 27, lowest of the throe, <br />shows that its water levels are moat likely flependeat upon the water level is <br />the wedge Impoundment located 50 feet away. The U569 personnel operating the <br />recorders prior to 1980 also support these findings, well 26, located between <br />wells 25 and 27, normally exhibits water levels higher then either 25 or 27. <br />Thin is not a normal ground water level gradieatr therefore, its water levels <br />should ba reviewed with eautioa. Perhaps, ae with Well 22, water ie being <br />trapped is the borehole. <br />Seven spoil walla mere completed is the fall of 1987. Three (Wall 59, 60, sad <br />. 61) ware coaryleted upgradieat of the Spoils spring 3 area, while Four (Walla 62 <br />to 65) ware completed in the Spoils Spring 1 area. The purpose of placing <br />aevernl walla at each site was to accurately 8af ins the poteatlometric surface <br />of the aDoila aquifer at each location. Water levels at all of these spoil <br />walla exhibit normal seasonal variations. Well 65 has been dry for the entire <br />period of record. It is located is nn area where the spoils are unsaturated. <br />Ground Water Level Summary. All alluvial walla ors showing dietinet seasonal <br />water level fluctuations in reepoaee to periods of precipitation recharge or the <br />lack of yrecipitatioa. Overburden and coal well water levels are fluctuating is <br />reepoaee to the precipitation recharge, induced ground water flow to the mice <br />pits, and is some eases, changes in reservoir water levels. Spoil well water <br />levels still indicate that only the furthest downelope highwall portions of the <br />spoil exhibit elgnificant amounts of saturation. <br />Grovad water Quality, 6zouad water samples were collected from 19 walla on a <br />biannual basis. is addition, two wells (SOV42 sad SSP25) that are required to <br />• be eamyled did not have enough water to sample. The parameter list used for sll <br />wells sampled this year is given on Table 4. Analyses have been performed by <br />ACZ Laboratory in Steamboat Spriage, Colorado eiaca May 31, 1983.
