Title Remediating historic mine sites in Colorado Type Journal Article
Year 1999 Publication Min. Eng. Abbreviated Journal
Volume (down) 51 Issue 8 Pages 32-35
Keywords Reclamation and conservation Groundwater problems and environmental effects geological abstracts: environmental geology (72 14 1) geomechanics abstracts: excavations (77 10 10) abandoned mine acid mine drainage environmental effect remediation United States Colorado
Abstract This article provides examples of reclamation and remediation in Colorado watersheds. The projects were undertaken by the US Environmental Protection Agency (EPA) Region 8, in cooperation with the Colorado Division of Minerals and Geology (CDMG), Colorado Department of Public Health and Environment (CDPHE), US Forest Service (USFS), the Bureau of Land Management (BLM), Bureau of Reclamation (BOR) and the US Geological Survey (USGS). These agencies collaborated on the environmental problems at abandoned mines. These samples involved the interaction of surface and ground waters with sulfide-bearing rocks, mine workings and surface mine spoils that produce acid solutions charged with heavy metals that are toxic to organisms. In these examples, acid mine drainage from historic mines in Colorado has been approached cooperatively with stakeholders. Each example emphasizes one aspect of the three-stage process. These stages include characterization and prioritization, hydrologic controls and the evaluation of long-term remediation activities.

Title Treatment of inorganic contaminants using permeable reactive barriers Type Journal Article
Year 2000 Publication J Contam Hydrol Abbreviated Journal
Volume (down) 45 Issue 1-2 Pages 123-137
Keywords acid mine drainage; adsorption; agricultural waste; aquifers; chemical reactions; chromium; concentration; contaminant plumes; decontamination; disposal barriers; dissolved materials; drainage; ground water; heavy metals; metals; nitrate ion; nutrients; permeability; phosphate ion; pollution; pump-and-treat; remediation; sulfate ion; waste disposal; water treatment mine water treatment Remediation Groundwater Metals Nutrients Radionuclides
Abstract Permeable reactive barriers are an emerging alternative to traditional pump and treat systems for groundwater remediation. This technique has progressed rapidly over the past decade from laboratory bench-scale studies to full-scale implementation. Laboratory studies indicate the potential for treatment of a large number of inorganic contaminants, including As, Cd, Cr, Cu, Hg, Fe, Mn, Mo, Ni, Pb, Se, Tc, U, V, NO3, PO4 and SO4. Small-scale field studies have demonstrated treatment of Cd, Cr, Cu, Fe, Ni, Pb, NO3, PO4 and SO4. Permeable reactive barriers composed of zero-valent iron have been used in full-scale installations for the treatment of Cr, U, and Tc. Solid-phase organic carbon in the form of municipal compost has been used to remove dissolved constituents associated with acid-mine drainage, including SO4, Fe, Ni, Co and Zn. Dissolved nutrients, including NO3 and PO4, have been removed from domestic septic-system effluent and agricultural drainage.

Title Asidik maden drenajinin (AMD) giderilmesinde uygulanan biyolojik yontemler. Biological methods applied in the treatment of acid mine drainage (AMD) Type Journal Article
Year 2006 Publication Madencilik = The = Journal of the Chamber of Mining Engineers of Turkey Abbreviated Journal
Volume (down) 45 Issue 1 Pages 35-45
Keywords acid mine drainage biodegradation methods microorganisms oxidation pollutants pollution remediation sulfides 22, Environmental geology
Abstract Acidic mine drainage (AMD) is a serious environmental problem in mining areas throughout the world. AMD occurs as a result of the natural oxidation of sulfide minerals when they are exposed to oxygen and water during their disposal and storage at the mining areas. Because it includes low pH and high concentrations of dissolved metals and sulphates, AMD can potentially damage to the environment. If the formation of AMD can't be prevented and controlled, it must be collected and treated to remove acidity and reduce the concentration of heavy metals and suspended solids before its release to the environment. Different types of microorganisms in the treatment of AMD can play a very important role in the development and the application of microbiological prevention, control and treatment technologies. The purpose of this article is to give information about the passive biological methods used in the treatment and the control of AMD and the role of microorganisms in these methods.

Title Agricultural soils irrigated with acidic mine water: Acidity, heavy metals, and crop contamination Type Journal Article
Year 2005 Publication Australian Journal of Soil Research Abbreviated Journal
Volume (down) 43 Issue 7 Pages 819-826
Keywords Contamination and remediation Irrigated agriculture Soil studies geographical abstracts: physical geography soils (71 5 14) international development abstracts: agriculture and rural development (74 1 8) ecological abstracts: terrestrial ecology (73 4 2) bioaccumulation irrigation agricultural soil acid mine drainage pH crop plant heavy metal China Far East Asia Eurasia
Abstract Agricultural soils irrigated with acidic mine water from the Guangdong Dabaoshan Mine, China, were investigated. The pH of the soils could be as low as 3.9. However, most of the mineral acids introduced into the soils by irrigation were transformed to insoluble forms through acid buffering processes and thus temporarily stored in the soils. Different heavy metals exhibited different fraction distribution patterns, with Zn and Cu being mainly associated with organic matter and Pb being primarily bound to oxides (statistically significant at P = 0.05). Although the mean of exchangeable Cd was greatest among the Cd fractions, there was no statistically significant difference between the exchangeable Cd and the oxide-bound Cd (the 2nd greatest fraction) or between the exchangeable Cd and the carbonate-bound Cd (the 3rd greatest fraction). It was also found that there were generally good relationships between the concentrations of various Zn, Cu, Pb, and Cd fractions and pH, suggesting that a major proportion of each heavy metal in the soils was mainly derived from the acidic irrigation water. The results also show that the crops grown in these soils were highly contaminated by heavy metals, particularly Cd. The concentration of Cd in the edible portions of most crops was far in excess of the limits set in China National Standards for Vegetables and Fruits and this can be attributable to the extremely high transfer rate of Cd from the soils to the crops under the cropping system adopted in the study area. < copyright > CSIRO 2005.
