Bowie Resources Limited Bowie No. 1 Mine • 1999 Annual Hydrology Report 64 to 731. The range for TDS was 244 to 1,900. The 1999 values for sulfate and TDS fall within the minimum and maximum values documented in the 1992 AHR, and are near the baseline values collected during the period of 1983-1985 of 302 for sulfates and 965 for TDS. OVWM GroundwaterMooitoring Wells: One piezometer (OVWM) is installed in the fill at the Orchard Valley West Mine. This well is currently monitored when accessible for water levels to evaluate fill stability. Monitoring results from 1999 indicate water levels consistent with past monitoring. North Fork Alluvium Grouudwater Monitoring Wells: Three (3) wells, MW-1, MW-2 and MW-3 (see Map No. 8-3) aze completed in the North Fork of the Gunnison alluvium During 1999 the wells were monitored montlily for water levels and showed typical seasonal fluctuations within previously established ranges. MW-1 and MW-3 were monitored quarterly for quality during 1999 to monitor potential groundwater effects stemming from the coal stockpile and load out facilities in the North Fork Valley. Well MW-1 is east of the load-out in an area that should be outside or above the area of influence of the coal stockpile and loadout area. Well MW-3 is southwest of the coal stockpile area in a location that should see the full impact of any potential groundwater degradation. The TDS level in the wells shows whether the groundwater in the area has been degraded. In 1993, the TDS in wells MW- l and MW-3 were 388 and 380 mg/l respectively. These values have been referred to as baseline values. However, upon further review, this well seasonally experiences wide swings in its TDS values. Well MW-1 had a TDS level of 1,440 mg/f in the first quarter, 320 mg/I in the third quarter and 420 mg/I in the fourth quarter of 1999. Well MW-3 had TDS values of less than 380 mg/I for all monitoring events. This data would show that the stockpile and load-out are not degrading the water in the alluvium. At the request of the DMG, we are including a graph outlining the normal rise and fall of TDS at MWO1. East Roatcap Creek Colluvium Grouudwater Monitoring Wells: Shallow groundwater monitoring wells, SM-5, SM-6, SM-7, SM-10 and SM-11 (see Map No. 4-1) are in the East Roatcap Creek drainage. The wells were monitored for water quality parameters, water levels, and Seld parameters to detect impacts associated with mining in the west pod. All of the wells were monitored semi-annually for water levels, field parameters and water quality. SM-7 is within the projected angle-of--draw of mine workings. Water levels from the five Roatcap Creek colluvial wells continued to show typical seasonal variability with water levels elevated in the spring and lower at the end of the year. No anomalies or impacts on water levels were observed in 1999 at these wells. i Pape 3
