The Oklahoma Plan for Tar Creek has listed four main objectives in the process: improving surface water quality, reducing exposure to lead dust, attenuating mine hazards, and land reclamation. [ 8 ] The University of Oklahoma's Department of Civil Engineering and Environmental Science has implemented a 1.2 million dollar passive water treatment ...
Acid mine drainage also affects the wildlife living within the affected body of water. Aquatic macroinvertebrates living in streams or parts of streams affected by acid mine drainage show fewer individuals, less diversity, and lower biomass. Many species of fish also cannot tolerate the pollution. [15]

[2] Although it is sometimes called "acid mine drainage", not all abandoned mine drainage is acidic. [3] [4]
There are tens of thousands of abandoned mines in the United States. Many abandoned mines pose environmental challenges, such as acid mine drainage. In Colorado alone, there are 18,382 abandoned mines. [34] The United States has had many different environmental disasters caused by these mines, such as the 2015 Gold King Mine waste water spill.
Mine safety incidents have been important parts of American occupational safety and health history. Mining has a number of environmental impacts . In the United States, issues like mountaintop removal , and acid mine drainage have widespread impacts on all parts of the environment.
Acid rock drainage is created when water and oxygen interact with sulphur-bearing minerals and chemicals in rocks. [17] Sulphuric acid is the most common chemical reaction that results from mining activities as the beneficiation process requires dissolving the minerals surrounding the ore, which releases metals and chemicals previously bound up ...
