LEETOWN (AP) - Scientists from the U.S. Geological Survey say a
byproduct of acid mine drainage treatment may be able to help
clean agricultural and municipal wastewaters.
The study was done at the agency's Leetown Science Center in West
Virginia. It shows that dried acid mine drainage sludge can be
used as a low-cost adsorbent to remove phosphorus from
Officials say the technology can potentially help lower acid mine
drainage treatment costs, prevent the degrading of aquatic
ecosystems and recycle valuable nutrients.
Acid mine drainage is produced whenever sulfide minerals from coal
and metal deposits are exposed to air and moisture. The resulting
acid and dissolved metals are toxic to most forms of aquatic life.
Untreated drainage has impacted more than 5,000 miles of streams
in the Appalachian region.
