  Abstract Acid mine drainage (AMD) is a serious problem in many watersheds where coal is mined. Passive treatments, such as wetlands and anoxic limestone drains (ALDs), have been developed, but these technologies show varying treatment efficiencies. A new passive treatment technique is a vertical flow wetland or successive alkalinity producing system (SAPS). Four SAPS in Pennsylvania were studied to determine changes in water chemistry from inflow to outflow. The Howe Bridge SAPS removed about 130 mg l (super -1) (40%) of the inflow acidity concentration and about 100 mg l (super -1) (60%) iron (Fe). The Filson 1 SAPS removed 68 mg l (super -1) (26%) acidity, 20 mg l (super -1) (83%) Fe and 6 mg l (super -1) (35%) aluminium (Al). The Sommerville SAPS removed 112 mg l (super -1) (31%) acidity, exported Fe, and removed 13 mg l (super -1) (30%) Al. The McKinley SAPS removed 54 mg l (super -1) (91%) acidity and 5 mg l (super -1) (90%) Fe. Acid removal rates at our four sites were 17 (HB), 52 (Filson1), 18 (Sommerville) and 11 (McKinley) g of acid per m (super 2) of surface wetland area per day (g/m (super 2) d (super -1) ). Calcium (Ca) concentrations in the SAPS effluents were increased between 8 and 57 mg l (super -1) at these sites. Equilibrators, which were inserted into compost layers to evaluate redox conditions at our sites, showed that reducing conditions were generally found at 60 cm compost depths and oxidized conditions were found at 30 cm compost depths. Deeply oxidized zones substantiated observations that channel flow was occurring through some parts of the compost. The Howe Bridge site has not declined in treatment efficiency over a six year treatment life. The SAPS construction costs were equal to about seven years of NaOH chemical treatment costs and 30 years of lime treatment costs. So, if the SAPS treatment longevity is seven years or greater and comparable effluent water quality was achieved, the SAPS construction was cost effective compared to NaOH chemical treatment. Construction recommendations for SAPS include a minimum of 50 cm of compost thickness, periodic replacement or addition of fresh compost material, and increasing the number of drainage pipes underlying the limestone.

  Title Abandoned mines drainage; impact assessment and mitigation of discharges from coal mines in the UK Type Book Chapter
  Year 2001 Publication Geoenvironmental engineering Engineering Geology Abbreviated Journal  
  Volume (down) Issue Pages 31-37  
  Keywords abandoned mines coal mines cost discharge drainage England environmental effects Europe feasibility studies Great Britain mine drainage mines mitigation pollution remediation Scotland United Kingdom Western Europe 22, Environmental geology  
  Abstract The UK has a legacy of pollution caused by discharges from abandoned coal mines, with the potential for further pollution by new discharges as groundwaters continue to rebound to their natural levels. In 1995, the Coal Authority initiated a scoping study of 30 gravity discharges from abandoned coal mines in England and Scotland. Mining information, geological information and water quality data were collated and interpreted in order to allow a preliminary assessment of the source and nature of each of the discharges. An assessment of the potential for remediation was made on the basis of the feasibility and relative costs of alternative remediation measures. Environmental impacts of the discharges and of the proposed remediation schemes were also assessed. The results, together with previous Coal Authority studies of discharges in Wales, were used by the Coal Authority, in collaboration with the former National Rivers Authority and the former Forth and Clyde River Purification Boards, to rank discharge sites in order of priority for remediation.

  Title Methodology for estimating the costs of treatment of mine drainage Type Journal Article
  Year 2001 Publication Proceedings of the Seventeenth International Mining Congress and Exhibition of Turkey Abbreviated Journal  
  Volume (down) Issue Pages 191-201  
  Keywords mine water treatment  
  Abstract Tetra Tech developed worksheets for the U.S. Department of the Interior, Office of Surface Mining (OSM) to allow a consistent, accurate, and rapid method of estimating the costs of long-term treatment of mine drainage at coal mines, in accordance with the Surface Mining Control and Reclamation Act (SMCRA) of 1977. This paper describes the rationale for the worksheets and how they can be used to calculate costs for site-specific conditions. Decision trees for selection of alternative treatments for acidic or alkaline mine drainage are presented.
