  • "Impact of Artisanal and SmallScale Mining on Water

    Water bodies, the source of drinking water for many rural households in mining areas are at risk of contamination due to artisanal and smallscale mining (ASM) activities. Water quality, therefore, remains a topical issue for policymakers and researchers. This research sought to achieve three objectives: firstly, to evaluate the effectiveness of existing policies and AFRICA: the impact of mining on the environment Afrik 21,The mining industry, mainly focused on the extraction of minerals and metals such as iron, copper, cobalt, nickel and cadmium, degrades ecosystems and contaminates the environment. “Oil, silver, copper, or gold are found in rocks containing sulphide ores, which release sulphuric acid when crushed and exposed to air and water.AMD: Impacts on aquatic life Lehigh University,The acid lowers the pH of the water, making it corrosive and unable to support many forms of aquatic life. Acid formation is most serious in areas of moderate rainfall where rapid oxidation and solution of exposed minerals can occur. Indeed, of the 19,308 km of United States streams reported degraded by acid mine drainage in 1970,
