Lower Maumee River

In 2012, Great Lakes Legacy Act (GLLA) sediment site characterization sampling project was conducted in 5 miles of the lower Maumee River. The sediment assessment showed the primary areas of sediment contamination were near the Duck Creek confluence study area, the City of Toledo wastewater treatment plant (WWTP), and the sway bridge. Two of these three areas are being targeted for potential cleanup of contaminated sediments to address beneficial use impairments.

A Data Gap Investigation is expected to be completed in 2021, followed by a Focused Feasibility Study in 2022.

Project Location

Sampling results indicated that Polycyclic Aromatic Hydrocarbons (PAHs) are the main constituent of concern at the Sway Bridge Contaminated Sediment Project Area. This area is primarily on the east side of the river around the second railroad bridge when headed upstream from the mouth. Sampling results indicated that polychlorinated biphenyls (PCBs) are the main constituent of concern at the WWTP Contaminated Sediment Project Area. This area is primarily on the west side of the river near the Toledo WWTP. The Duck Creek area has since been listed as needing no further GLLA action.

Project Benefits:

  • Reduce or remove impairments to negatively affected aquatic fish and bug communities.
  • Improve overall environmental health and usability of this area.

Project Objectives:

  • Determine if cleanup of contaminated sediment is warranted and if so, clean up/removal of contaminated sediments.
  • Improve water quality, habitat, and biological communities.
  • Encourage economic redevelopment and reuse of the area.

Project Partners:

Ohio EPA and U.S. EPA are working with community partners and other federal, state, and local governmental agencies to evaluate and cleanup any contaminated sediments (as appropriate) utilizing the Great Lakes Restoration Initiative (GLRI) and other non-federal funding.

The Maumee AOC Committee works toward fishable and swimmable waters in the Maumee Area of Concern and delisting the beneficial use impairments. The Committee is working towards all major restoration projects being completed by 2025, through collaboration of partners and volunteer opportunities by its facilitating organization, Partners for Clean Streams. The committee is made up of representatives from various organizations, citizens, businesses and non-government agencies to build long term solutions to the area’s water quality issues.
