Ryerson Creek Outfall Sediment Remediation

History & Location

Located in Muskegon, Michigan, the Ryerson Creek Outfall (RCO) Sediment Remediation Project is a 12-acre portion of the Muskegon Lake AOC, which encompasses 4,179-acres of drowned river mouth lake that flows into the easter shore of Lake Michigan. The contaminated lake sediments were likely caused by historic storm sewer inputs and legacy industries including sawmills, automotive production, coal gasification operations, a foundry and other timer operations. The contaminants of concern include petroleum, lead, arsenic, cadmium, and PAHs.
