• Bowie Resources Limited <br />Bowie No. 1 Mine <br />1997 Annual Hydrology Report <br />244 to 1,900 mg/L The 1997 values for sulfate and TDS fall within the minimum and maY~mum <br />values documented in the 1992 AHR. <br />OVWM GroandwaterMoaitoring Wells: <br />Well OV WM was monitored semi-annually for water levels only to assess the stability of the <br />West mine fill constructed across East Roatcap Creek. Well OV WM showed typical water level <br />fluctuations during 1997 within the normal range established for this site. (See Tab 5, Figure 5) <br />North Fork Alluvium Groundwater Monitoring Wells: <br />Three (3) wells, MW-1, MW-2 and MW-3 (see Map No. 8-3) are completed in the North Fork <br />of the Gunnison alluvium During 1997 the wells were monitored monthly for water levels and <br />showed typical seasonal fluctuations within previously established ranges (see Tab 5, Figures 6, <br />7 and 8). MW-1 and MW-3 were monitored quarterly for quality during 1997 to monitor <br />potential groundwater effects stemming from the coal stockpile and load out facilities in the <br />North Fork Valley. Well MW-1 is east ofthe load-out in an area that should be outside or <br />above the area of influence of the coal stockpile and load-out facilities. MW-3 is southwest of <br />• the coal stockpile area in a location that should see the fiill impact of any potential groundwater <br />degradation. The TDS level in the wells shows whether the groundwater m the area has been <br />degraded. In 1993, the TDS in wells MW-1 and MW-3 were 388 and 380 mg/1 respectively. <br />These values are considered baseline values. Well MW-1 had a TDS level of 880 mg/1 in the <br />first quarter, 390 mg/1 in the third quarter and 1100 mg/1 in the fourth quarter of 1997. Well <br />MW-3 had TDS values of less than 380 mg/l for all monitoring events. This data would show <br />that the stockpile and load-out are not degrading the water in the alluvium <br />East Roatcap Creek Coluuvium Groandwater Monitoring Wells: <br />Shallow groundwater monitoring weps, SM-5, SM-6, SM-7, SM-10 and SM-11 (see Map No. <br />4-1) are in the East Roatcap Creek drainage. The wells were monitored for water quality <br />pazameters, water levels, and field parameters to detect impacts associated with mining in the <br />west pod. All of the wells were monitored semi-annually for water levels, field parameters and <br />water quality. None of these wells aze within the projected angle-of--draw of mine workings. <br />Water levels in these five colluvial wells continue to show typical seasonal variability with <br />elevated water levels in the spring which recede throughout the year. No anomalies or impacts <br />to expected water levels or water quality were observed at these wells during 1997 as shown by <br />water quality analysis that yielded resuhs compazable to previously collected data. <br />• Pege 3 of 7 <br />
