Title Recent technology related to the treatment of acid drainage Type Journal Article
Year 1994 Publication Earth and Mineral Sciences Abbreviated Journal
Volume 63 Issue 3 Pages 53-55
Keywords (up) acid mine drainage coal mine remediation passive treatment 3 Geology
Abstract The generation of acid mine drainage is a serious environmental problem associated with coal mining. The chemistry of acid mine drainage is outlined. The prevention and minimization of acid mine drainage formation is examined. The in situ inhibition and remediation of acid mine drainage is described. Methods for the passive treatment of acid mine drainage after formation are discussed. The design of treatment systems is considered. -P.M.Taylor

Title The roles of spent mushroom substrate for the mitigation of coal mine drainage Type Journal Article
Year 1994 Publication Compost Science and Utilization Abbreviated Journal
Volume 2 Issue 4 Pages 84-94
Keywords (up) acid mine drainage rehabilitation coal mining spent mushroom substrate 3 Geology
Abstract Spent mushroom substrate (SMS) has been used widely in coal mining regions of the USA as the primary substrate in constructed wetlands for the treatment of coal mine drainage. In laboratory and mesocosm studies, SMS has emerged as one of the substrates for mine water treatment. Provided the pH of the mine water does not fall below 3.0, SMS can be used in the mitigation plan. However, neither Mn nor dissolved ferric Fe appears to be treatable using reducing SMS wetlands. Since after a few years much of the nonrefractive organic carbon in SMS wil have been decomposed and metabolized, carbon supplementation can significantly extend the life of the SMS treatment wetland and improve water treatment. -from Authors

Abstract In the report, wetland technology is described in which the main reactive layer is limestone gravel (rather than organic material) which is overlain by a fine gravel filter and soil. The three-year project included laboratory and field studies. Vertical aerated wetlands, simulated by columns, constructed in the field and in the laboratory, were operated during the project. The report presents a summary of results given in previous reports and summaries of results obtained using water from Butte, MT, and field studies at the Rockford Tunnel, near Idaho Springs, CO.

Title Successive Alkalinity-Producing Systems (SAPS) for the Treatment of Acid Mine Drainage Type Journal Article
Year 1994 Publication Proceedings, International Land Reclamation and Mine Drainage Conference Abbreviated Journal
Volume 1 Issue Pages 195-204
Keywords (up) acid mine drainage; alkalinity; anaerobic environment; calcium carbonate; chemical reactions; experimental studies; pH; pollutants; pollution; remediation; water quality SAPS mine water RAPS
Abstract Constructed wetland treatment system effectiveness has been limited by the alkalinity-producing, or acidity-neutralizing, capabilities of systems. Anoxic limestone drains (ALD's) have allowed for the treatment of approximately 300 mg/L net acidic mine drainage, but current design guidance precludes using successive ALD's to generate alkalinity in excess of 300 mg/L because of concerns with dissolved oxygen. “Compost” wetlands designed to promote bacterially mediated sulfate reduction are suggested as a means of generating alkalinity required in excess of that produced by ALD's. Compost wetlands create two basic needs of sulfate reducing bacteria; anoxic conditions resulting from the inherent oxygen demand of the organic substrate, and quasi-circumneutral pH values resulting from the dissolution of the carbonate fraction of the compost. However, sulfate reduction treatment area needs are generally in excess of area availability and/or cost effectiveness. Second generation alkalinity-producing systems demonstrate that a combination of existing treatment mechanisms has the potential to overcome current design concerns and effectively treat acidic waters ad infinitum. Successive alkalinity-producing systems (SAPS) combine ALD technology with sulfate reduction mechanisms. SAPS promote vertical flow through rich organic wetland substrates into limestone beds beneath the organic compost, discharging the pore waters. SAPS allow for conservative wetland treatment sizing calculations to be made as a rate function based on pH and alkalinity values and associated contaminant loadings. SAPS potentially decrease treatment area requirements and have the further potential to generate alkalinity in excess of acidity regardless od acidity concentrations.
