After years of planning and many months of construction, the Abandoned Mine Drainage Treatment System at Allegheny Land Trust Wingfield Pines Conservation Area was officially dedicated on June 3, 2010. 

            The AMD Treatment System filters 43 tons of iron oxide annually from one billion gallons of mine discharge.  Some early sampling indicates that iron oxide is reduced from 13.9 mg/L in Pond #1 to 0.1 mg/L at the discharge site into Chartiers Creek.
