DRMS MINE WATER SAMPLING PROGRAM: SAMPLE LOCATIONS AND <br />PROTOCOL <br />Barrett Lavergne <br />Bowie Resources LLC <br />Introduction: <br />The purpose of the DRMS Mine Water Sampling Program is to collect water <br />inflow from multiple locations for certain parameter analysis to determine if the Bowie <br />No. 2 mine will impact the surface or subsurface water. Compliance with the Hydrologic <br />Monitoring Plan 2.05.6 of the Permit Application Coal Mining in Colorado, is <br />determined by monitoring springs of water flow of 5 gallons or more per minute, in or <br />adjacent to the permit area. Monitoring these springs annually, allows for field testing <br />and lab parameter testing at each monitoring site. Annual monitoring, facilitates the <br />identification of any impact the mine is having on the balance of the hydrologic cycle. <br />The parameters included in the lab testing are included in Surface Water List 1. <br />Locations: <br />The sample locations picked for the annual monitoring sites were decided based <br />on hydro-geologic conditions. Consistent water inflow trends in Bowie No. 2 Mine have <br />been seen near normal faults, reverse faults, strike-slip faults, open joints, roof bolts, and <br />lithologic drilling locations. Steady water flows have been observed throughout the mine <br />near major faults. Water inflow trends seem to diminish in these areas as the mining <br />faces work further away, thus creating most of the heavy drainage near working faces. <br />Observations: <br />Monitoring site No. 1 is located in cross cut 1 of the 1 S` East mains in entry No. 2 <br />(see Location #1). This sample location was picked due to its low elevation, relative to <br />surrounding areas, which allows the water to drop from open cracks and joints, and then <br />guided along gutters and drip pans to the sample location. There is clearly an abundant <br />amount of water being guided to this location, evident by the pooling of water in the <br />nearby sump, although water flow trends have decreased in this area. The general <br />conditions observed from the sample taken on 07/07/09 at 12:30 were that of a clear <br />water sample with a small quantity of suspended solids. The field parameter tests <br />demonstrated slightly basic water with a pH of 8.9 and a conductivity of 5.7 mS/cm. The <br />flow rate of 5 gal/min of this slightly cool sample, had a temperature of 19 degrees <br />Celsius. This slightly cool temperature is most likely due to the availability of contact <br />time between the low temperature and high velocity intake airway. <br />Monitoring site No. 2 was picked due to the location near the D5 fault in the <br />North-East Sub-Mains in cross cut No. 4, entry 2 (see Location #2). The location of this <br />site was taken from the end of a pipe that was being guided to a sump. The source of <br />water to this sump was identified from a pump in beltline pumping highly suspended <br />solid water. This site location is labeled as contaminated due to the source of water. No <br />water sample was taken and should be ceased in the future at this location. <br />Monitoring site No. 3 was picked due to its association with the D5 fault in the <br />"old" 2°d North Mains, between cross cut 6 and 7 in entry No. 2 (See Location #3). No <br />sample was taken due to the lack of availability of H2O. This is evidence of diminishing
