As part of a program to examine the ability of existing control technologies to meet proposed federal guidelines for the quality of aqueous effluents from coal mines, intensive studies of water, coal, and overburden chemistry were conducted at a surface mine in southern Illinois during 1976-1977. Sampling locations included the receiving stream (which flows partly in a man-made channel through the mine-site), drainage from old and new settling ponds, drainage from an old soil area and intake water and slurry for the coal cleaning operation. No chemical treatment of mine effluent was practiced at this site. In general, mine effluent complied with federal and state standards for pH, manganese, and iron. However, total suspended solids concentrations often exceeded permitted maximum values in the effluent and the receiving stream due to the use of relatively small settling ponds (low retention time) and sediment contributions from erosion of unlined banks along the diversion channel for the receiving stream. Accompanying overburden sampling and analysis completed for this project indicated a positive value for the net neutralization potential.
