The Fate and Function of Acid Mine Drainage | Ohio Water ...
The Fate and Function of Acid Mine Drainage | Ohio Water ...

As water leaches out, this acid ,mine, drainage (AMD) contains naturally high levels of ,acidity, and dissolved minerals and metals, some of which are toxic. The AMD mixes with the surrounding water and causes an increase in ,acidity, and concentration of toxic metals, a condition which impairs the water and prevents aquatic life from thriving.
