  19. WHAT MINERS  Acid mine drainage or acid rock drainage, is the acidic water that drains out of above-ground orCANNOT SOLVE:  under-ground coal and metal mines. It may form g y inside the mine or several kilometers downstream.Acid Mine Drainage It can occur during mining operations and even when operations has finished and the site is abandoned. It affects stream and river ecosystems by increasing acidity, acidity depleting oxygen, and releasing heavy oxygen metals, such as aluminum, iron, manganese, and zinc.
