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.
