conditions left behind from a by-gone era, like many of the streams in our
Township's Scrubgrass Run, which drains into Chartiers Creek, is polluted by abandoned coal mine drainage,
commonly referred to as AMD.
Run AMD Project mitigates this pollution passively using a collection
pond. The orange
sediment recovered from the site, referred to as "yellow-boy" is recycled and used for pigment in paints and dyes.
board member Keith Breitenstein has dyed our conservancy T-shirts with
this retrieved orange iron oxide precipitate
from the site. Adding the orange iron pigment to cement
yields a lasting warm orange
color when pouring sidewalks and steps or mortaring walls and repointing bricks
- quite an improvement over the usual boring grey. Robin Anthony
came up with this idea after noticing the
red iron oxide mortar in her turn of the century Crafton home.
grant for the Scrubgrass Run Abandoned Mine
Drainage (AMD) project was obtained in 1995 from the
DEP. The grant was for $62,000. Matching
funds for the project was obtained from Scott Township, the
Office of Surface Mining, The Scott Conservancy, and the Heinz
In a1996 awards
ceremony, the Scott Conservancy was named Environmental Group of the Year for 1996
by the Allegheny
County Conservation District for its AMD passive reclamation
Scrubgrass Run. The Award recognized the conservancy's joint
effort with the Chartiers Valley
School District and the township to clean up Scott's Scrubgrass Run watershed,
polluted by abandoned coal mine drainage. Scrubgrass Run flows
into Chartiers Creek.
Scott Conservancy obtained an additional grant for $50,000
from the DEP to install a mechanical aeration system to
increase the efficiency of the procedure at the Scrubgrass Run
Scott Conservancy was awarded an
additional grant of $100,000 from the EPA for further
remediation at the Scrubgrass site. Work began in the
Spring of 2001.
McGuirk, one of our board members, is seeking volunteers to
help with a Scrubgrass Run stream monitoring project.
Scrubgrass Run is the stream whose waters are being cleansed of
precipitates by our AMD project.
Run Abandoned Mine Drainage Project was conceived and constructed by
engineering professionals, the Scott Conservancy would also like to thank the
volunteers who donated their time to this project, for those who help spread the
word about our efforts to reduce the abandoned mine drainage
problem, and those
who educate the public by leading hikes through our facilities.
