  Title Long-term Performance of Passive Acid Mine Drainage Treatment Systems Type Journal Article
  Year (up) 2003 Publication Mine Water Env. Abbreviated Journal  
  Volume 22 Issue 3 Pages 118-129  
  Keywords acidity acid load aerobic wetlands anaerobic wetlands anoxic limestone drains limestone leach beds open limestone channels slag leach beds successive alkalinity producing systems vertical flow wetlands  
  Abstract State and federal reclamation programs, mining operators, and citizen-based watershed organizations have constructed hundreds of passive systems in the eastern U.S. over the past 20 years to provide reliable, low cost, low maintenance mine water treatment in remote locations. While performance has been reported for individual systems, there has not been a comprehensive evaluation of the performance of each treatment type for a wide variety of conditions. We evaluated 83 systems: five types in eight states. Each system was monitored for influent and effluent flow, pH, net acidity, and metal concentrations. Performance was normalized among types by calculating acid load reductions and removals, and by converting construction cost, projected service life, and metric tonnes of acid load treated into cost per tonne of acid treated. Of the 83 systems, 82 reduced acid load. Average acid load reductions were 9.9 t/yr for open limestone channels (OLC), 10.1 t/yr for vertical flow wetlands (VFW), 11.9 t/yr for anaerobic wetlands (AnW), 16.6 t/yr for limestone leach beds (LSB), and 22.2 t/yr for anoxic limestone drains (ALD). Average costs for acid removal varied from $83/t/yr for ALDs to $527 for AnWs. Average acid removals were 25 g/m2/day for AnWs, 62 g/m2/day for VFWs, 22 g/day/t for OLCs, 28 g/day/t for LSBs, and 56 g/day/t for ALDs. It appears that the majority of passive systems are effective but there was wide variation within each system type, so improved reliability and efficiency are needed. This report is an initial step in determining passive treatment system performance; additional work is needed to refine system designs and monitoring.

  Title Software Update to Better Predict Costs of Treating Mine Drainage Type Journal Article
  Year (up) 2005 Publication Mine Water Env. Abbreviated Journal  
  Volume 24 Issue 4 Pages 213-215  
  Keywords AMD prediction software  
  Abstract The U.S. Office of Surface Mining (OSM) is updating a popular software program that helps government agencies and mine water practioners predict what it will cost to treat acid mine drainage (AMD). Developers expect to release the update, AMDTreat Version 4.0, before the end of 2005. The new version will offer additional tools, expanded features, and a better user interface.

  Title Small-Scale Chemical Changes Caused by In-stream Limestone Sand Additions to Streams Type Journal Article
  Year (up) 2006 Publication Mine Water Env. Abbreviated Journal  
  Volume 25 Issue 4 Pages 241-245  
  Keywords acid mine drainage aluminum calcium limestone sand sediment stream liming West Virginia  
  Abstract In-stream limestone sand addition (ILSA) has been employed as the final treatment for acid mine drainage discharges at Swamp Run in central West Virginia for six years. To determine the small-scale longitudinal variation in stream water and sediment chemistry and stream biota, we sampled one to three locations upstream of the ILSA site and six locations downstream. Addition of limestone sand significantly increased calcium and aluminum concentrations in sediment and increased the pH, calcium, and total suspended solids of the stream water. Increases in alkalinity were not significant. The number of benthic macroinvertebrate taxa was significantly reduced but there was no effect on periphyton biomass. Dissolved aluminum concentration in stream water was reduced, apparently by precipitation into the stream sediment.
