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 (down) 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

Title Heavy-metal sludges as smelter feedstock Type Journal Article
Year 1994 Publication Engineering and Mining Journal Abbreviated Journal
Volume (down) 195 Issue 9 Pages 25-30
Keywords Metals Mining Groundwater Pollution USA Colorado California Gulch 3 Geology
Abstract Many industries produce a waste-water stream high in heavy metals. Disposal of sludge from these wastewater treatment plants has become increasingly difficult and expensive in the US due to passage of the Resource Conservation and Recovery Act's 'land disposal ban' for hazardous wastes. Innovative methods can be found for dealing with such wastes. For example, in performing a mandated clean-up under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Asarco's California Gulch water-treatment plant in Colorado meets CERCLA clean-up goals while using a waste water treatment sludge as a smelter feedstock, recovering incidental saleable metals, and producing non-hazardous products. In this plant, Asarco treats acidic mine-drainage water having high metal concentrations and uses the waste sludge generated as a lime replacement in lead smelting operations. -Author

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 (down) 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.
