|Most individuals are familiar
with the orange coated stream bottoms of the coal mining regions.
Hundreds of streams throughout Pennsylvania, West Virginia, Maryland, Virginia,
Ohio, Kentucky, Tennessee, and Alabama are affected by abandoned mine drainage
(AMD). AMD is caused by the oxidation of materials surrounding the
coal, forming a mild acid similar to vinegar. Metals, such as iron,
aluminum and manganese, are leached from these materials killing most aquatic
There is hope! Utilizing the developing
technology of passive treatment, watersheds are being restored.

Coal has been mined in the United States
since the mid 1700's. It has powered the industrial revolution and
has helped win two world wars. Thousands of men have lost their lives
during the slow and painful evolution of mining. More...
Abandoned mine drainage is the result
of materials, normally found buried deep underground, becoming exposed
to water and oxygen. Pyrite is the primary material responsible for
the formation of AMD. More...
By utilizing environmentally friendly
materials, such as limestone and compost, acidity and metals can effectively
be removed from the discharge. Passive treatment systems range from
a simple limestone filled ditch to a Vertical Flow System with miles of
Thousands of acres of abandoned minelands
are spread across the United States. Through the use of circulating
fluidized bed coal ash, gob material at these sites can be neutralized
and the landscape restored to the orginal contours. More...
