Complementary approaches to integrate microbial diversity into revegetation and phytoremediation on abandoned mine tailings
Mine tailings are the principal byproduct of ore processing for metal extraction. They represent an important source of contamination for the surrounding environment due to wind-driven dust dispersion, water erosion, and leaching. Composed mainly of silt- or sand-sized grains, tailings are low in …

Abandoned Mine Land Impacts on Tributaries in the Upper Yakima River Watershed, Eastern Cascades, Washington
Effluent from abandoned mine lands (AMLs) in several drainages in Washington’s Eastern Cascades flows into the Yakima River. Similar sites in Idaho and Colorado are known producers of heavy metals and acid mine drainage. I determined the effects of nine AMLs on water quality in four tributaries to …

Evaluation of strategies for rehabilitation of selected abandoned/historic mine sites in the Giyani Greenstone Belt, Limpopo Province of South Africa
… has left the country with a negative legacy of abandoned mines that present environmental problems, and public health and safety concerns. The common physical and environmental problems of most of these abandoned mines are associated with open shafts, unstable slopes of waste dumps and pits, and …

Mitigation of water quality and ecosystem impacts of roadway construction through retrospective engineering analyses
… H between Buckhannon and Elkins, West Virginia, mine spoils and land use features related to historic mining were disturbed. An assessment of the water quality, benthic macro invertebrates, and fish populations was conducted to ascertain the condition of the water and to assess the biological …

A comparative legal approach to mining rehabilitation funding schemes in South Africa and Western Australia
… and social challenges posed by historically abandoned mine sites to host communities, little effort has been made by the mining industry and governments to rehabilitate the environment. Mine rehabilitation projects are typically costly. In many instances, mining companies do not have a …

The influence of mine waste contamination on invertebrates and fish in the Methow River Valley, Okanogan County, Washington (U.S.A.)
A study of mine-waste contamination effects on Methow River habitat on the eastern slopes of the north Cascade Mountains in Washington state, U.S.A., revealed trace element impacts on invertebrates and fish. Ore deposits in the area were mined for gold, silver, copper and zinc until the early …

Development and Implementation of Integrative Bioassessment Techniques to Delineate Small Order Acid Mine Drainage Impacted Streams of the North Fork Powell River, Southwestern Virginia
Acid mine drainage (AMD) results from the oxidation of pyretic mineralogy, exposed by mining operations to oxygen and water. This reaction produces sulfuric acid and liberates heavy metals from the surrounding mineralogy and impairs water quality and freshwater communities. The U.S. Army Corps of …
