20. WHAT
MINERS
Acid mine drainage or acid rock drainage, is the
acidic water that drains out of above-ground or
CANNOT
SOLVE:
under-ground coal and metal mines. It may form
inside the mine or several kilometers downstream.
Acid
Mine
Drainage
It can occur during mining operations and even
when operations has finished and the site is
abandoned.
It affects stream and river ecosystems by increasing
acidity, depleting oxygen, and releasing heavy
metals, such as aluminum, iron, manganese, and
zinc.
