  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 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.

  Abstract Acid mine drainage (AMD) causes environmental pollution that affects many countries having historic or current mining industries. Preventing the formation or the migration of AMD from its source is generally considered to be the preferable option, although this is not feasible in many locations, and in such cases, it is necessary to collect, treat, and discharge mine water. There are various options available for remediating AMD, which may be divided into those that use either chemical or biological mechanisms to neutralise AMD and remove metals from solution. Both abiotic and biological systems include those that are classed as “active” (i.e., require continuous inputs of resources to sustain the process) or “passive” (i.e., require relatively little resource input once in operation). This review describes the current abiotic and bioremediative strategies that are currently used to mitigate AMD and compares the strengths and weaknesses of each. New and emerging technologies are also described. In addition, the factors that currently influence the selection of a remediation system, and how these criteria may change in the future, are discussed.

  Volume 1 Issue 5 Pages 335-343  
  Keywords acid mine drainage acidophilic microorganisms heavy metals iron oxidation iron reduction remediation sulfate reduction wetlands Wheal Jane  
  Abstract Passive (wetland) treatment of waters draining abandoned and derelict mine sites has a number of detrac-tions. Detailed knowledge of many of the fundamental processes that dictate the performance and longevity of constructed systems is currently very limited and therefore more research effort is needed before passive treatment becomes an “off-the-shelf” technology.

  Title Design, construction and performance of a full-scare compost wetland for mine-spoil drainage treatment at quaking houses Type Journal Article
  Year 1999 Publication Jciwem Abbreviated Journal  
  Volume 13 Issue 5 Pages 313-318  
  Keywords Wetlands and estuaries geographical abstracts: physical geography hydrology (71 6 8) composting constructed wetland design performance assessment United Kingdom EnglandCounty Durham  
  Abstract Acidic spoil-heap drainage, containing elevated concentrations of iron, aluminium and manganese, has been polluting the Stanley Burn in County Durham for nearly two decades. Following the success of a pilot-scale wetland (the first application of its kind in Europe), a full-scale wetland was installed. Waste manures and composts have been used as the main substrate which is contained within embankments constructed from compacted pulverized fuel ash. The constructed wetland, which cost less than £20,000 to build, has consistently reduced iron and aluminium concentrations and has markedly lowered the acidity of the drainage. A third phase of activities at the site aims to identify and eliminate pollutant-release 'hot spots' within the spoil.
