2. Hvdroloaic Monitoring <br />A. Surface Water - H-G Coal Company continues to monitor <br />four surface water locations. The locations include two <br />sites near the loadout on Dry Creek and two sites near <br />the reclaimed mine and shop area on Hayden Gulch. All <br />locations are sampled on a semi-annual basis. <br />Minimal flows were evident on Dry Creek during 1990. A <br />sample was available on both sites in June, but <br />unavailable in September. Minimal flows were due to the <br />drought conditions being experienced in the region. <br />Analysis of samples taken at Hayden Gulch indicate <br />drought conditions as well. Insufficient standing water <br />existed at the upper site and no samples were obtained. <br />Minimal flows also were encountered at the lower site but <br />samples were nevertheless taken. Due to extremely low <br />flows again this year along Hayden Gulch there is no <br />potential to significantly impact down stream reaches of <br />Hayden Gulch or the Williams Fork river. <br />Analysis for the surface water monitoring locations on <br />Dry Creek and Hayden Gulch are presented in Exhibits 1 <br />and 2. <br />8. Groundwater - H-G Coal Company continued groundwater <br />monitoring at the reclaimed minesite, reclaimed shop <br />area, and the loadout area. <br />The HG-2 well is monitored down dip of the reclaimed <br />minesite for quality and water level. No significant <br />changes in water quality were noticed during 1990. The <br />water level in the well has gradually dropped about ten <br />feet over the past three years and this trend continued. <br />This drop in water level is likely a result of reduced <br />recharge due to low amounts of precipitation in the past <br />few years. <br />The HG-1 well is monitored down dip of the reclaimed shop <br />area for water quality and level. Results of analysis of <br />samples taken during 1989 show consistent results with <br />1987 and 1988. No indication of impacts on groundwater <br />are evident. <br />The UC-2 well is monitored for water depth. No changes <br />have occurred. <br />
