Assessment of water quality in streams draining coal-producing areas in Ohio
C.L. Pfaff, D.R. Helsel, D.P. Johnson, C.G. Angelo
1981, Water-Resources Investigations Report 81-409
Water quality in the coal-producing areas of eastern Ohio was studied in a two-phase investigation between May 1975 and August 1976. Results of phase one, a reconnaissance of water quality at 150 sites, indicated that acid mine drainage generally occurred where abandoned drift or strip mines were located, whereas areas...
