Laboratory experiments were carried out to evaluate the effectiveness of antibacterial substances and antibiotics against thiobacillus ferrooxidans, the organism responsible for bacterial- mediated acidic mine drainage. Twenty-two antibiotics and two anti- bacterial substances were evaluated. The most promising compound, n- serve, was evaluated further in column studies. A column study was completed using coal mine waste and hard rock mine waste spoils. Eight columns containing 7 kg of each spoil were established using varying concentrations of n-serve applied to the spoils. The columns were leached once a week with 1 inch of rain (distilled water). Effluent was collected and monitored for water quality parameters. Only the highest n-serve dose produced column leachates significantly better in quality than that of the control columns. A monolithic controlled release formulation utilizing acrylonitrile rubber was successfully developed and tested for use with nitrapyrine, the active ingredient in n-serve. The application of n- serve to an actual coal and/or hard rock waste spoil material warrants future study.
