Ottawa River

The Ottawa River 2010 cleanup removed approximately 250,000 cubic yards (CY) of contaminated sediments in the upper reaches of the lower 9 miles of the river around Suder Ave bridge to Upton Ave bridge. The lower 3 miles were not dredged but monitored for natural recovery to support the removal of Beneficial Use Impairments. The main contaminants were polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), heavy metals (primarily lead), and oil and grease.

Project Location:

The Ottawa River cleanup was divided into four reaches. Reach 1 being the most downstream reach, extending from the mouth of the Ottawa River to approximately river mile 3.5. Reaches 2, 3, and 4 extending, approximately, from river miles 3.5 to 9.

Project Benefits:

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

Project Objectives:

  • Remove contaminated sediments from approximately 6 miles of the Ottawa River. Improve water quality, habitat, and biological communities.
  • Remove contact and consumption advisories
  • Encourage economic redevelopment and reuse of the area.
