The
JB2 discharge before treatment. |
This
abandoned mine drainage seep, located on Cherry Valley
Road near Burgettstown in Washington County, used to
dump over 15 tons of iron and 2 tons of aluminum each
year into the headwaters of Raccoon Creek. This pollution
source, known as Joffre Branch 2, or JB2, was targeted
for cleanup by the Raccoon Creek Watershed AMD Survey
and Restoration Plan completed in 2000.
Many
organizations and agencies teamed up with the Raccoon
Creek Watershed Association to treat the JB2 Discharge.
The Independence Conservancy accepted the donation
of property surrounding the JB2 discharge to build a
Vertical Flow Wetland (VFW), a passive system which
removes the iron compounds and acidity from the source
pictured above.
The
Washington County Conservation District secured construction
grants from the US Department of the Interior's Office
of Surface Mining, the PA Department of Environmental
Protection's Southwest Regional Office and the DEP Growing
Greener Grants Program. Construction began in the fall
of 2003 and was completed in the fall of 2004 at a total
cost of $422,535.
Time has shown a need to modify the system. In 2008, the vertical flow wetland is slated for conversion to a FeAlMn Bed, a different type of passive treatment system which will be more effective at treating the JB2 discharge. FeAlMn stands for Iron (Fe), Aluminum (Al) and Manganese (Mn), common pollutants in Acid Mine Drainage.
The JB2 AMD Treatment System is a major step toward
our common goal of eliminating Acid Mine Drainage (AMD)
pollution from Raccoon Creek, thereby restoring water
quality, wildlife habitat and recreational values.
