  Title Treatment of acid rock drainage in a meromictic mine pit lake Type Journal Article
  Year 2006 Publication Journal of environmental engineering Abbreviated Journal  
  Volume 132 Issue 4 Pages 515-526  
  Keywords Pollution and waste management non radioactive Groundwater problems and environmental effects geological abstracts: environmental geology (72 14 2) geomechanics abstracts: excavations (77 10 10) meromictic lake acid mine drainage mine waste copper water pollution Bacteria microorganisms Canada Vancouver Island British Columbia North America  
  Abstract The Island Copper Mine pit near Port Hardy, Vancouver Island, B.C., Canada, was flooded in 1996 with seawater and capped with fresh water to form a meromictic (permanently stratified) pit lake of maximum depth 350 m and surface area 1.72 km2. The pit lake is being developed as a treatment system for acid rock drainage. The physical structure and water quality has developed into three distinct layers: a brackish and well-mixed upper layer; a plume stirred intermediate layer; and a thermally convecting lower layer. Concentrations of dissolved metals have been maintained well below permit limits by fertilization of the surface waters. The initial mine closure plan proposed removal of heavy metals by metal-sulfide precipitation via anaerobic sulfate-reducing bacteria, once anoxic conditions were established in the intermediate and lower layers. Anoxia has been achieved in the lower layer, but oxygen consumption rates have been less than initially predicted, and anoxia has yet to be achieved in the intermediate layer. If anoxia can be permanently established in the intermediate layer then biogeochemical removal rates may be high enough that fertilization may no longer be necessary. < copyright > 2006 ASCE.

  Title Adding sodium hydroxide to study metal removal in a stream affected by acid mine drainage Type Journal Article
  Year 1993 Publication Research Paper, US Department of Agriculture, Forest Service Abbreviated Journal  
  Volume 465 Issue 17 Pages  
  Keywords pH stream mine drainage remediation zinc copper sodium hydroxide USa Montana Beartooth Mountains Fisher Creek 3 Geology  
  Abstract Fisher Creek, a stream affected by acid mine drainage in the Beartooth Mountains of Montana, was studied to determine the extent to which copper (Cu) and zinc (Zn) would be removed from stream water when pH was increased by a pulse of sodium hydroxide (NaOH). Although the pH adjustment study indicated that precipitated Fe(OH) “SUB 3” (am) could rapidly remove Cu and Zn from a stream affected by acid mine drainage, the pH should be maintained in an optimal range (7 to 8.5) to maximize removal by adsorption. -from Authors

  Title Mitigation of water contamination at the historic Ferris-Haggarty Mine, Wyoming Type Journal Article
  Year 1999 Publication Min. Eng. Abbreviated Journal  
  Volume 51 Issue 8 Pages 49-53  
  Keywords Reclamation and conservation Groundwater problems and environmental effects geological abstracts: environmental geology (72 14 1) geomechanics abstracts: excavations (77 10 10) abandoned mine copper hydrogeology mine drainage United States Wyoming Ferris Haggarty Mine  
  Abstract An historic underground copper mine in Wyoming is discharging neutral but copper-laden water into a pristine creek. The EPA-deferred site qualifies for reclamation by the Wyoming Abandoned Mine Land (AML) program. The cleanup goal is to restore the discharge so that the creek can eventually support a trout fishery. Hydrological and geochemical investigations underground have suggested two sources of mine water: one clean and the other containing copper. Results of bench- and pilot-scale tests support the viability of using low-cost passive treatment techniques to reduce copper concentrations in the near-freezing mine discharge.
