The Partnership for Acid Drainage Remediation (PADRE) is a European-based scientific-technical association dedicated to acid mine water related topics.
PADRE was founded in 2003 in Johannesburg, South Africa, due to the steadily increasing problems related to water in Europe. It is a sister organisation of the International Mine Water Association - IMWA and was publicly launched during IMWA’s Mine Water 2004 conference, in Newcastle upon Tyne (UK) in September 2004. [1]
The Summitville mine was a gold mining site in the United States, located in Rio Grande County, Colorado 25 miles (40 km) south of Del Norte. It is remembered for the environmental damage caused in the 1980s by the leakage of mining by-products into local waterways and then the Alamosa River.
Land rehabilitation as a part of environmental remediation is the process of returning the land in a given area to some degree of its former state, after some process has resulted in its damage. Many projects and developments will result in the land becoming degraded, for example mining, farming and forestry.
Calcium silicate is the chemical compound Ca2SiO4, also known as calcium orthosilicate and is sometimes formulated as 2CaO·SiO2. It is also referred to by the shortened trade name Cal-Sil or Calsil.
The King River is a major perennial river in the West Coast region of Tasmania, Australia.
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.
The Colomac Mine was a privately owned and operated open pit gold mine located 220 km northwest of Yellowknife in the Northwest Territories in Canada. The Colomac mine operated between 1990–1992, and 1994–1997. It was operated by Neptune Resources Limited that had little success in making a profit during its operation. In 1994, the mine had reopened under Royal Oak Mines Inc. Both Neptune Resources and Royal Oak Mines where both owned and operated by Peggy Witte. Due to low gold prices and high cost of mining, Royal Oak Mines was forced into bankruptcy. The Federal Government of Canada became owners of the mine, along with the related environmental issues. A major cleanup effort is under way to prevent the mine from polluting the environment, but this might be too late at this stage. This mine is now owned and controlled by the Indigenous and Northern Affairs department of the Federal government, while Public Works and Government services is the current contracting authority.
Mount Lyell Mining and Railway Company was a Tasmanian mining company formed on 29 March 1893, most commonly referred to as Mount Lyell. Mount Lyell was the dominant copper mining company of the West Coast from 1893 to 1994, and was based in Queenstown, Tasmania.
Padre means father in many Romance languages, and it may also refer to:
The Blackwater River is a 34.3-mile-long (55.2 km) river in the Allegheny Mountains of eastern West Virginia, USA. Via the Black Fork, it is a principal tributary of the Cheat River. Via the Cheat, the Monongahela and the Ohio rivers, it is part of the watershed of the Mississippi River and drains an area of 142 square miles (370 km2). It is a true blackwater stream, owing to spruce and hemlock trees in its watershed, the tannins of which impart a tea or amber color to its water.
Iron Mountain Mine, also known as the Richmond Mine at Iron Mountain, is a mine near Redding in Northern California, US. Geologically classified as a "massive sulfide ore deposit", the site was mined for iron, silver, gold, copper, zinc and pyrite intermittently from the 1860s until 1963. The mine is the source of extremely acidic mine drainage which also contains large amounts of zinc, copper and cadmium. One of America's most toxic waste sites, it has been listed as a federal Superfund site since 1983.
Mahanoy Creek is a 51.6-mile-long (83.0 km) tributary of the Susquehanna River in Northumberland and Schuylkill counties, Pennsylvania. There are at least 35 sources of acid mine drainage in the creek's watershed. Anthracite was mined in the upper part of the Mahanoy Creek watershed in the 19th and 20th centuries. Mahanoy Creek's tributaries include Schwaben Creek, Zerbe Run, Little Mahanoy Creek, Shenandoah Creek, and North Mahanoy Creek. Little Mahanoy Creek and Schwaben Creek are two streams in the watershed that are unaffected by acid mine drainage. Schwaben Creek has a higher number and diversity of fish species than the main stem.
The International Mine Water Association (IMWA) is the first scientific-technical association worldwide dedicated to mine water related topics.
The outflow of acidic liquids and other pollutants from mines is often catalysed by acid-loving microorganisms; these are the acidophiles in acid mine drainage.
Spring Creek Debris Dam is an earthfill dam on Spring Creek, a tributary of the Sacramento River, in Shasta County in the U.S. state of California. Completed in 1963, the dam, maintained by the U.S. Bureau of Reclamation, serves primarily to collect severe acid mine drainage stemming from the Iron Mountain Mine. The dam forms the Spring Creek Reservoir, less than 1 mile (1.6 km) long. Spring Creek and South Fork Spring Creek flow into the reservoir from a 16-square-mile (41 km2) watershed. The dam is directly upstream from the city of Keswick, California and the Keswick Reservoir. The operation is part of the Trinity River Division of the Central Valley Project.
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have effect on the quality of human health and biodiversity. Some mining methods may have such significant environmental and public health effects that mining companies in some countries are required to follow strict environmental and rehabilitation codes to ensure that the mined area returns to its original state.
Pit water, mine water or mining water is water that collects in a mine and which has to be brought to the surface by water management methods in order to enable the mine to continue working.
The Industrial and Mining Water Research Unit is one of several research entities based in the School of Chemical and Metallurgical Engineering at the University of the Witwatersrand, Johannesburg. It provides research as well as supervision to masters and doctorate students within the University; as well as consulting to industry.
The Askam Borehole is a borehole that is located in Luzerne County, Pennsylvania, in the United States. It is situated in the watershed of Nanticoke Creek north of PA 29 and Dundee Road and contributes several million gallons of acid mine drainage to that creek daily. The borehole also discharges large loads of iron and other substances. It was constructed by the Pennsylvania Department of Environmental Protection in the early 1970s and drains mine water from the South-East Mine Pool Complex. The discharges of the borehole have been treated by active treatment systems and artificial wetlands.
Abandoned mine drainage is a form of water pollution involving water that has been polluted by contact with mines, typically coal mines. Although it is sometimes called "acid mine drainage", not all abandoned mine drainage is acidic.
According to a survey completed by the Colorado Geological Survey between 1991 and 1999, the number of abandoned mines in Colorado is 18,382. The Arkansas Headwaters, Las Animas River, Rio Grande Headwaters, Alamosa, and Uncompahgre were the priority watersheds studied in this survey. In the survey, analysis was completed with Environmental Degradation Measures ranging from none to extreme. Results showed 26 abandoned mines with extreme degradation and mineral hazards, 219 with significant degradation, and 672 potentially significant hazards.
