ion calcium-sulfate/bicarbonate type. Chemical parameters were relatively stable over the year with greater <br /> ionization as water levels were lower. <br /> Some of the parameters such as iron and ammonia exhibited high concentrations during certain sampling <br /> events. Reasons for these spikes are not known,however, they may be linked to well completion and the steel <br /> casing. <br /> Station W-16 is located in the cast pit reclaimed area. Water levels remained relatively stable over the <br /> 1989 monitoring period ranging from 92.92 in March to 93.83 in December. Water levels decreased during <br /> the four 1989 samplings. Over the five year monitoring period water levels have generally increased, which <br /> indicates the development of the aquifer in the reclaimed area. The water is a sodium-sulfate type with higher <br /> conductivity and TDS over that observed in other wells. The water also exhibits an elevated level of iron and <br /> manganese. <br /> Concern has been expressed by CMLRD that as an aquifer develops in the reclaimed area, springs and <br /> seeps may occur into surface waters of Stollsteimer Creek During April of 1987 and 1988,a spring and seep <br /> survey was conducted in the reclaimed area. No springs or seeps were located in either survey. A spring and <br /> seep survey was conducted on March 27, 1989, in the area of the mine pits and surface disturbance area. One <br /> spring was observed originating from the Stollsteimer Creek bank just downstream from surface station S-2. <br /> Flow was measured at approximately 3 gallons per minute. Water chemistry of the spring was analyzed <br /> (Appendix 2) and found to be between that sampled in Stollstcimer Creek station S-2 and Well A-1. This <br /> survey will be conducted again in 1990 to assess the development and interface of this aquifer. <br /> 1 <br /> I <br /> I <br /> I <br /> i <br /> I <br />
