Any water that runs through the mine trails may become polluted due to the chemicals present in the mines.

These chemicals include sulfuric acid and dissolved iron.

Such chemicals contaminate the drinking water and are very harmful to humans.

Therefore, we can conclude that "contamination of water supplies" is a problem associated most with mining.
