Fecal coliform concentrations in runoff from a grazed, reclaimed surface mine

The relatively scarcity of flat or moderately sloping land in Central Appalachia make reclaimed surface mined lands attractive for agricultural uses. A reclaimed surface coal mine in southern West Virginia was placed under grazing management during the 1984 and 1985 grown seasons. Discharge was collected from summer-grazed watersheds of about 2.8 ha and 8.9 ha and analyzed, by the membrane-filtration method, for fecal coliforms (FC). Prior to grazing in 1984, FC counts were < 200/100 ml. During the grazing season, FC ranged from < 0/100 ml to > 1000/100 ml in 1984 and from 0/100 ml to > 2500/100 ml in 1985. FC counts remained high during warm periods for several months after grazing ceased. It was concluded that the bacteriological quality of receiving streams was impacted by grazing the reclaimed area and recommended standards for point sources were often exceeded; however, the FC counts did not appear to be any greater than what would have been expected from grazed, undisturbed areas. Reclaimed surface mines areas in Appalachia have the potential to be a valuable flat land resource and grazing appears to be an alternative post mine land use that affects bacteriological water quality in a similar manner as natural pastures. However, good management practices may be necessary to avoid bacterial contamination of adjacent bodies of water.
