The water pollution is caused by acid that drains from the “Iron Mountain” mine, known as acid drainage. Acid drainage is serious stuff. With a pH value of 0, the groundwater near the “Iron Mountain” has been found to be 10,000 times more acidic than battery acid (this is VERY acidic). It’s the highest concentration of acid in the world.

Pollution from Mining

Mining provides essential raw materials for an industrialized society. However, it causes serious pollution of surface and groundwater. Transferring minerals from deep below the surface to the surface promotes oxidation reactions. Oxidation of iron salts and of sulfur-containing materials in the presence of water leads to highly acidic solutions.
