Mine drainage is metal-rich water formed from a chemical reaction between water and rocks containing sulfur-bearing minerals. The resulting chemicals in the water are sulfuric acid and dissolved iron. Some or all of this iron can come out as solids to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage.
