parameters was completed on a sample from point C-1 in March. No significant difference in <br />the 2000 monitoring results from baseline or historical measurements was noted. <br />Surface water monitoring points NF-1 (North Fork upstream), NF-2 (North Fork downstream) <br />and NF-3 (North Fork downstream) are designed to monitor the water quality in the North Fork <br />of the Gunnison River above and below the disturbed surface mine site of the Sanbom Creek <br />Mine. Monitoring point NF-3 was established in September 1997 to monitor mining-related <br />water quality impacts from the West Valley Fill coal refuse pile. It should be noted that NF-3 is <br />also downstream from the Town of Somerset and monitoring results for this station most likely <br />reflect impacts from domestic water use, leakage from sanitary sewers, the Beaz Mine discharges <br />and other factors that are not related to the Sanborn Creek Mine. <br />Spring monitoring points SP-1 through SP-11 aze monitored and the results compazed with <br />baseline and historic monitoring data. A significant change in the quality or quantity of flow <br />from these springs and seeps after retreat mining might indicate that the mine might be impacting <br />these water resources. Spring SP-1 is located above a planned longwall panel and springs SP-2 <br />through SP-6 are located within the angle-of--draw ofplanned longwall panels. Overburden in <br />excess of 2,000 feet separates these springs and seeps from the mine. <br />' Spring I is a seep at a depression neaz a grove of aspen trees. Though the seep may have flowed <br />into and out of the depression when it was monitored previous to 1993, outflow from the <br />depression has been recorded only once since then (in April 1997), and this flow was likely a <br />' result of snowmelt runoff than of spring flow. The data recorded aze from samples taken from <br />the seep and surface runoff water that have collected in the depression. <br />Spring 2 is likely the re-emergence of runoff that had infiltrated into the soils that lie in this small <br />ephemeral channel. Flows, if any, aze typically recorded in the spring and eazly summer, with <br />the greatest flows measured at the same time as snowmelt and spring runoff. This is also <br />' supported by field pazameter measurements that are similaz to those of surface and meteoric <br />water. Springs 3, 5, and 6 aze also likely the result of the same type of re-emerged surface runoff <br />water, as flow diminishes from spring to summer, and have moderate pH, low conductivity, and <br />vary in temperature. <br />Spring 4 is the only high mountain spring (of Springs 1-6) that usually has consistent flow. Due <br />' to snow pack conditions, Springs 1- 6 (as well as all high mountain sites) could not be monitored <br />during April. No significant difference in the 1999 monitoring results for Springs 1 - 6 from <br />baseline or historical measurements was noted. <br />' Spring 7 is located in the cut-bank of the Coal Gulch trail. While historical data for Spring 7 <br />' indicate that the spring has typically been dry, some flows in the spring have been measured. <br />There also appears to be some influence of groundwater in these limited flows, as conductivity <br />measurements are higher than surface water flows. No significant difference in the 1999 <br />' monitoring results for Spring 7 from baseline or historical measurements was noted. <br />Based on the quality and location of Spring 8, it was determined that the source of the spring was <br />' the abandoned Oliver Mine. Until 1999, flows from this spring were been relatively consistent. <br />' 166 <br />
