State lauds Sewickley Creek iron-oxide removal project
[2008-5-16]
The Sewickley Creek Watershed Association and Iron Oxide Recovery Inc. have received a Governor's Award for Environmental Excellence for their iron-oxide removal project at the abandoned Marchland Mine site in Lowber.
The association partnered with Iron Oxide Recovery of Pittsburgh in 1999 to create the state's first commercially successful resource recovery project, according to the state Department of Environmental Protection.
For decades, the mine had discharged gallons of iron-polluted water every minute into Sewickley Creek. Installation of a treatment system in 2006 was funded by $1.3 million in Growing Greener grants.
So far, the project has resulted in the recovery and recycling of 4,000 tons of wet iron sludge that otherwise would have gone to landfills at the disposal cost of at least $150,000. Also, the system now treats between 1,400 and 2,200 gallons per minute of mine water containing 70 to 85 milligrams per liter of iron.
