  Title Utilization of a ceramic membrane for acid mine drainage treatment Type Journal Article
  Year 1997 Publication Tailings and Mine Waste '97 Abbreviated Journal  
  Volume Issue Pages 453-460  
  Keywords acid mine drainage; Black Hawk Colorado; Central City Colorado; ceramic materials; Colorado; cost; disposal barriers; geochemistry; Gilpin County Colorado; heavy metals; mines; organic compounds; pollution; remediation; surface water; tailings; United States; utilization; volatile organic compounds; volatiles; waste disposal mine water treatment  
  Abstract BASX Systems LLC has developed a treatment system based on ceramic membranes for the removal of heavy metals from an acid mine drainage stream. This stream also contained volatile organic compounds that were required to be removed prior to discharge to a Colorado mountain stream. The removal of heavy metals was greater than 99% in most cases. A decrease of 30% in chemicals required for treatment and a reduction by more than 75% in labor over a competing technology were achieved. These decreases were obtained for operating temperatures of less than 5 degrees C. This system of ceramic microfiltration is capable of treating many different types of acid mine waste streams for heavy metals removal.

  Title Constructed vertical flow aerated wetlands Type RPT
  Year 1994 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords acid mine drainage; aeration; Butte Montana; carbonate rocks; case studies; clastic sediments; Clear Creek County Colorado; Colorado; construction; controls; fluid dynamics; gravel; heavy metals; Idaho Springs Colorado; limestone; Montana; pollution; rates; sedimentary rocks; sediments; Silver Bow County Montana; substrates; tailings; United States; waste water; water; water management; water quality; water treatment; wetlands 22, Environmental geology  
  Abstract In the report, wetland technology is described in which the main reactive layer is limestone gravel (rather than organic material) which is overlain by a fine gravel filter and soil. The three-year project included laboratory and field studies. Vertical aerated wetlands, simulated by columns, constructed in the field and in the laboratory, were operated during the project. The report presents a summary of results given in previous reports and summaries of results obtained using water from Butte, MT, and field studies at the Rockford Tunnel, near Idaho Springs, CO.

  Title Experimental diversion of acid mine drainage and the effects on a headwater stream Type Journal Article
  Year 1999 Publication Water-Resources Investigations Report Abbreviated Journal  
  Volume Wri 99-4018-A Issue Pages 123-130  
  Keywords abandoned mines acid mine drainage algae benthonic taxa biomass biota Colorado experimental studies heavy metals Lake County Colorado Leadville Colorado metals mines pH Plantae pollution remediation Saint Kevin Gulch Colorado tracers United States USGS water zinc  
  Abstract An experimental diversion of acid mine drainage was set up near an abandoned mine in Saint Kevin Gulch, Colorado. A mass-balance approach using natural tracers was used to estimate flows into Saint Kevin Gulch. The diversion system collected about 85 percent of the mine water during its first year of operation (1994). In the first 2 months after the diversion, benthic algae in an experimental reach (stream reach around which mine drainage was diverted) became more abundant as water quality improved (increase in pH, decrease in zinc concentrations) and substrate quality changed (decrease in rate of metal hydroxide deposition). Further increases in pH to levels above 4.6, however, led to lower algal biomass in subsequent years (1995-97). An increase in deposition of aluminum precipitates at pH greater than 4.6 may account for the suppression of algal biomass. The pH in the experimental reach was lower in 1998 and algal biomass increased. Mine drainage presents a complex, interactive set of stresses on stream ecosystems. These interactions need to be considered in remediation goals and plans.
