Wingfield Pines AML Treatment Site. After years of planning and many months of construction, the Abandoned Mine Drainage Treatment System at ALT's 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.
Watch this video put together by the Western PA Coalition for Abandoned Mine Reclamation for an overview of the project.
