37 have exhibited, in 1995, the lowest rater levels on record. This is due to dewaterinq • <br />from the adjacent mining pit. <br />Spoils. Three veils, 22, 23, and 24 are completed in the upper region of spoils (above <br />the Wadge Impoundment) which is generally unsaturated. Well 23 9ometlme9 shows water in <br />late February, !larch, and April as snow melts quickly of£ this westerly facing slope. <br />Well 24 has Deen dry for the entire period of record. The 3.8 feet of saturation observed <br />in Well 22 is most likely incorrect since adj scent Wells 23 and 24 are normally dry. The <br />suspect eater levels in Well 22 may be a result of water trapped in the borehole <br />(perhaps by a boulder in the spoils that the borehole does not completely penetrate). <br />Three yells, 25, 26, and 27 are situated in lover spoils adjacent to the Wadge Impoundment <br />which receives spoils water discharge. All three of these wells were outfitted with <br />continuous recorders operated by the V. 9. Geological Survey (VSGS) until the end of 1983. <br />Well 25, the highest upgradient of these three yells on the spoils slope, Sndieated an <br />absence of recharge in 1987, 1988, 1990, and 1991, but exhibited recharge in all other <br />years since 1953. Well 27, lowest of the three, shoes that its eater levels are most <br />likely dependent upon the eater level in the Wadge Ivpoundment located 50 feet away. <br />These findings are also supported by the VSGS personnel operating the recorders prior to • <br />1934. Well 26, located between Wells 25 and 27, normally exhibits very little seasonal <br />variability and rater levels higher than either 25 or 27. This is not a normal ground <br />eater level gradient; therefore, its water levels should De revlered with caution. <br />Perhaps, as with Well 22, water is being trapped in the borehole. <br />Seven spoil veils sere completed in the fall of 1937. Three (Well 59, 60, and 61) sere <br />completed upgradient of the Spoils Spring M3 area, while four (Wells 62 to 65) were <br />cos~leted in the Spoils Spring N1 area. The purpose of placing several wells at each site <br />was to accurately define the poteniiometric surface of the spoils aquifer at each <br />location. Water levels at Wells 59 through 61 have experienced an increase between July <br />and September of 1994. This is due to regrading of topsoil in this area that occurred <br />during this time frame. This regrading alfected Spoil Spring N3 immediately doangradient <br />of these three spoil wells and thereby aflected the water levels in those yells. Water <br />levels at all other spoil yells exhibit normal seasonal variations. Well 65 has been dry <br />for the entire period of record. It Ss located in an area where Che spoils are <br />unsaturated. <br />• <br />4 <br />
