Therefore, all recorded <br />monitoring events are considered Operational. <br />Monitoring Wells MW -1, MW -2 and MW -3 are located at the coal stockpile /truck dump /train loadout area and were <br />drilled during September 1982 to determine the essential hydrologic functions of the North Fork alluvial valley floor. <br />Two of the wells, MW -2 and MW -3, have since been determined to be installed in areas which are no longer <br />classified as alluvial valley floor. (TR -13) <br />There is no baseline collection possible for points initiated after the influence of mining. <br />Figure Number 5 <br />
