  Title Sizing and performance estimation of coal mine drainage wetlands Type Journal Article
  Year 1999 Publication Ecological Engineering Abbreviated Journal  
  Volume 12 Issue 3-4 Pages 353-372  
  Keywords mine water treatment coal mine drainage constructed wetlands efficiency first-order removal loading rate removal kinetics sizing zero-order removal constructed wetlands water-quality iron kinetics removal model phosphorus retention mechanism design Wetlands and estuaries geographical abstracts: physical geography hydrology (71 6 8) acid mine drainage effluent performance assessment remediation wetland management  
  Abstract The effectiveness of wetland treatment of acid mine drainage (AMD) was assessed using three measures of performance: treatment efficiency, area-adjusted removal, and first-order removal. Mathematical relationships between these measures were derived from simple kinetic equations. Area-adjusted removal is independent of pollutant concentration (zero-order reaction kinetics), while first-order removal is dependent on concentration. Treatment efficiency is linearly related to area-adjusted removal and exponentially related to first-order removal at constant hydraulic loading rates (flow/area). Examination of previously published data from 35 natural AMD wetlands revealed that statistically significant correlations exist between several of the performance measures for both iron and manganese removal, but these correlations are potentially spurious because these measures are derived from, and are mathematical rearrangements of, the same operating data. The use of treatment efficiency as a measure of performance between wetlands is not recommended because it is a relative measure that does not account for influent concentration differences. Area-adjusted removal accounts for mass loading effects, but it fails to separate the flow and concentration components, which is necessary if removal is first-order. Available empirical evidence suggests that AMD pollutant removal is better described by first-order kinetics. If removal is first-order, the use of area-adjusted rates for determining the wetland area required for treating relatively low pollutant concentrations will result in undersized wetlands. The effects of concentration and flow rate on wetland area predictions for constant influent loading rates also depend on the kinetics of pollutant removal. If removal is zero-order, the wetland area required to treat a discharge to meet some target effluent concentration is a decreasing linear function of influent concentration (and an inverse function of flow rate). However, if removal is first-order, the required wetland area is a non-linear function of the relative influent concentration. Further research is needed for developing accurate first-order rate constants as a function of influent water chemistry and ecosystem characteristics in order to successfully apply the first-order removal model to the design of more effective AMD wetland treatment systems.

  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 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.
