water quality parameters as it is located downstream of the East mine <br />facilities. Wells BO1 through B06 and Well B08 are monitored semi-annually for <br />water levels to assess slope stability in and around the East Mine facilities. <br />Patterns typically associated with these wells in the past were again evident <br />during the 1994 monitoring. Wells BO1, B03, BOS, B06, and B08 *p~~~ed dry <br />throughout the year. Wells B02 and B04 showed moderate water level fluctuations <br />within the established normal ranges previously documented. The water level in <br />Well B07 was lower than the 1993 measurements but still higher than prior years <br />monitoring. Conductivity values at B07 re*~~~ed within the range of values <br />previously established. Othertronitored parameters fluctuated slightly within <br />established ranges. The 1993 report indicated that sulfate and total dissolved <br />solids appeared to be slightly elevated. In 1994 sulfate was 140 mg/1 compared <br />to the 1993 average of 380 mg/1. The 1994 TDS value was 604 mg/1 compared to <br />the 1993 average of 1,188 mg/1. No explanation is offered for the reduction of <br />these values in 1994 other than the 1994 data is a single monitoring event. <br />• OVNM C3tO[R~IIJ4a47~t MONI70RING WELLS <br />Well OWd~1 (see Map No. 4-1) was monitored ironthly for water level only to assess <br />stability of the West Mine fill constructed over East Roatcap Creek. Well OVWM <br />showed typical water level fluctuations within the normal range established for <br />this site during 1994. <br />t7DA1H FORK ALTIJVIiM GROIRiDNfATEft MONITORING WELLS <br />Three wells, MW-1, ~-2, and NN7-3 (see Map No. 8-3) are crnq~leted in the North <br />Fork Gunnison alluvium. During 1994 the wells were ironitored monthly for water <br />levels and showed typical seasonal fluctuations within previously established <br />ranges. MW-1 and MW-3 were monitored quarterly for quality during 1994 to <br />monitor potential groundwater effects stemming fran the coal stockpile and <br />loadout facilities located in the North Fork Valley. Well MW-1 is east of the <br />loadout in an area that should be outside or above the area of influence of the <br />coal stockpile and loadout facilities. Well MW-3 is southwest of the coal <br />stockpile area in a location that should see the full impact of any potential <br />groundwater degradation. The first quarter monitoring from MW-1 showed elevated <br />• levels of Calcium, Magnesium, Sodium and Sulfate. The last three quarters of <br />monitoring showed much lower values for these parameters. Excluding the first <br />quarter monitoring results for MW-1 the quality of MW-1 and MW-3 are similar. <br />3 <br />
