Reporting included water level and quality monitoring of alluvial wells, <br />water level monitoring of bedrock wells, water level and quality monitoring of the flooding mine <br />workings, and monitoring of springs and seeps in the affected area. <br />Monitoring Frequency <br />The monitoring frequency was met in accordance with the approved plan during 2003 and 2004. <br />No deviations from the plan were noted. <br />Surface Water tuantity and Quality <br />Surface water monitoring has been eliminated at this site. The mine has no appreciable impact <br />to the surface water system. <br />Ground Water Quantity and Quality <br />Data collected during 2003 and 2004 indicates no unexpected or abnormal changes to ground <br />water levels from previously reported monitoring data. Monitoring indicates minor changes in <br />NM-20 and NM-22 that do not seem to result from any mine related impact. Water level in SF-2 <br />remains stable. <br />Well Zone Distance from 1999 2000 2001 2002 2003 2004 <br /> mined area <br />NM-20 Ovbn 6000 ft 349 ft 349 ft 351 ft 364 ft 369 ft 373 ft <br />NM-21 Coal 4000 ft 740 ft 739 ft 701 ft 718 ft >750 >750 <br />NM-22 Ovbn 10,000 ft 414 ft 407 ft 401 ft 407 ft 419 ft 409 ft <br />SF-2 Ovbn 3000 ft 675 ft 656 ft 641 ft 645 ft 645 ft 646 ft <br />Bedrock well water quality sampling is no longer required due to the large distances of these <br />wells from the mined area. <br />Office of Office of Colorado <br />Mined Land Reclamation Active and Inactive Mines Geological Survey <br />
