i <br />new monitoring well was installed during 1990. Well GMP-1 was <br />installed approximately 600 feet south of GP-5 and well GMP-1 is <br />completed in the HI aquifer. .Table 1-1 presents basic well data <br />for all wells monitored in 1990. <br />Springs with greater than 5 gpm are required to be monitored <br />to further define the ground-water quality. The flow from the <br />springs were all less than 5 gpm during 1990. <br />Table 1-2 presents the pit and well dewatering data and volume <br />of water used for dust depression for Trapper Mine for 1990. This <br />data shows that, on an average, approximately 48 and 17 gpm were <br />pumped from the Trapper Mine pits and dewatering wells <br />respectively. The D pit dewatering in 1989 was greater than three <br />• times the 1990 while the Dwell dewatering was very similar in 1989 <br />and 1990. This data is useful in interpreting water-level changes. <br />Surface-water flow and quality have been monitored at the <br />Flume, Pyeatt, Johnson, No Name, Coyote and Buzzard sites during <br />1990. The Johnson, No Name, Buzzard, Coyote, West Buzzard, Ute, <br />Pyeatt and East Pyeatt sites are at Trapper's NPDES sites 001, 002, <br />003, 005, 006, 008, 009 and 011, respectively. <br />• <br />1-2 <br />
