  Title Acid Mine Water Treatment using Engineered Wetlands Type Journal Article
  Year 1990 Publication Int. J. Mine Water Abbreviated Journal

  Abstract 400 systems installed within 4 years During the last two decades, the United States mining industry has greatly increased the amount it spends on pollution control. The application of biotechnology to mine water can reduce the industry's water treatment costs (estimated at over a million dollars a day) and improve water quality in streams and rivers adversely affected by acidic mine water draining from abandoned mines. Biological treatment of mine waste water is typically conducted in a series of small excavated ponds that resemble, in a superficial way, a small marsh area. The ponds are engineered to first facilitate bacterial oxidation of iron; ideally, the water then flows through a composted organic substrate that supports a population of sulfate-reducing bacteria. The latter process raises the pH. During the past four years, over 400 wetland water treatment systems have been built on mined lands as a result of research by the U.S. Bureau of Mines. In general, mine operators find that the wetlands reduce chemical treatment costs enough to repay the cost of wetland construction in less than a year. Actual rates of iron removal at field sites have been used to develop empirical sizing criteria based on iron loading and pH. If the pH is 6 or above, the wetland area (in2) required is equivalent to the iron. load (grams/day) divided by 10. Theis requirement doubles at a pH of 4 to 5. At a pH below 4, the iron load (grams/day) should be divided by 2 to estimate the area required (in2).

  Title Environmental considerations of active and abandoned mine lands: lessons from Summitville, Colorado Type Journal Article
  Year 1995 Publication US Geological Survey Bulletin Abbreviated Journal  
  Volume 2220 Issue 38 Pages  
  Keywords acid mine drainage mining environmental effect remediation environmental assessment USA Colorado Summitville 1 Geography  
  Abstract Extreme acid-rock drainage is the dominant long-term environmental concern at the Summitville mine and could have been predicted given the geological characteristics of the deposit. Extensive remedial efforts are required to isolate both unweathered sulfides and soluble metal salts in the open-pit area and mine-waste piles from weathering and dissolution. Results of studies as of late 1993 indicate that mining at Summitville has had no discernible short-term adverse effects on barley or alfalfa crops irrigated with Alamosa River water. Remediation of the site will help to ensure that no adverse effects occur over the longer term. -from Editor

  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.
