ARCO Refinery (Wellsville, New York)
An oil refinery once operated on land currently home to the State University of New York's Wellsville campus. As a result of the historical refinery practices, the groundwater was contaminated with hydrocarbons. We designed a wetland system as a long-term solution to treat 280,000 gallons per day of contaminated groundwater from the former ARCO refinery.

The design incorporates an upgrade of the adjacent rails to trails and paths, restoration of the adjacent river swale and a 20-acre site plan restoration plan that utilizes native plants (trees, shrubs, wildflowers, grasses and wetland plants). Our engineered wetland system provided an ecologically based, low maintenance, long term solution that turned a challenging problem into a community amenity.
