An example would be Acid Mine Drainage. Acidic water can flow out of abandoned coal mines. Mining has xposed rocks which contain the sulphurbearing mineral, Pyrite. This mineral reacts to air and water to form sulphuric acid. When it rains, the diluted acid gets into rivers and streams and can even seep into underground sources of water.
