The acidic and metal-rich AMD is a major source of environmental pollution, contaminating nearby surface waters and groundwater, harming ecosystems and rendering water unsuitable for drinking. [24] AMD can persist for extended periods, even long after mining activities have ceased, leading to continual environmental degradation.
