1 supply. This usage appears to have little effect on water level in the well, however, the <br />usage has decreased concentrations of the metal and other parameters being sampled. <br />' Deep wells completed in the Fruitland Formation were sampled at stations W-ti, W-9, <br />W-10, W-17, and W-18. Wells W-17 and W-18 were eliminated from sampling under the <br />' current program. The general water level fluctuation cycle of these wells is an increase in <br />level from January through June, a decrease from July through October and a slight increase <br />in November and December (Appendix 2). Station W-6 exhibited the greatest fluctuations <br />' ranging nearly 20 feet (Table 1) and was nearly dry when measured in September 1990. <br />Water quality of the deep wells was similar to that of the surface and alluvial waters. The <br />waters are a mixed ion calcium-sulfate bicarbonate type. Chemical parameters were <br />' relatively stable over the year with greater ionization as water levels were ]over. <br />Station W-16 is located in the east pit reclaimed area. Water level increased during the <br />1991 monitoring period. Over the seven year monitoring period water levels have generally <br />increased; however, from the second quarter of 1989 through 1990, water levels decreased <br />' due to low precipitation and infiltration. The water is asodium-sulfate type with higher <br />conductivity and TDS over that observed in other wells. The water also exhibits an elevated <br />level of iron and manganese. Some of the parameters such as iron and ammonia exhibited <br />high concentrations during certain sampling events. Reasons for these spikes are not known, <br />however, they may be linked to well completion and the steel casing. <br />' Concern has been expressed by CMLRD that as an aquifer develops in the reclaimed <br />area, springs and seeps may occur into surface waters of Stollsteimer Creek. During April <br />of 1987 and 1988, a spring and seep survey was conducted in the reclaimed area. No springs <br />or seeps were located in either survey. A spring and seep survey was conducted on March <br />27, 1989, in the area of the mine pits and surface disturbance area. One spring was <br />observed originating from the Stollsteimer Creek bank just downstream from surface station <br />S-2. Flow was measured at approximately 3 gallons per minute. Water chemistry of the <br />spring was analyzed and found to be between that sampled in Stollsteimer Creek station S-2 <br />and Well A-1. No springs were observed during the March 1990 sampling. During A'farch <br />' 1991, some seepage was noted along the bank of Stollsteimer Creek. Also observed during <br />1991 along the newly reclaimed toe of the east pit area was a seep at the discharge point <br />of the rock drain under the east pit. This seep was observed as a wet spot during the <br />' March, June and September samplings. No measurable flow was observed during any of the <br />samplings. <br />1 <br />
