  • WHATMINERSCANNOTSOLVE:

    Acid mine drainage or acid rock drainage, is the acidic water that drains out of above-ground or under-ground coal and metal mines. It may form

    inside the mine or several kilometers downstream.

    It can occur during mining operations and even when operations has finished and the site is when operations has finished and the site is abandoned.

    It affects stream and river ecosystems by increasing acidity depleting oxygen and releasing heavy acidity, depleting oxygen, and releasing heavy metals, such as aluminum, iron, manganese, and zinc.
