Significant progress has been made in the Niagara River Area of Concern (AOC) since the Remedial Action Plan (RAP) process was first started in 1987. The infographic on the right summarizes the progress and key activities related to the Niagara River RAP since 1987. Successes achieved over the past 36 years include significant improvements in water quality, and the clean-up of contaminated sediments.
The Niagara River offers several ecological, recreational and economic beneficial water uses such as power generation, tourism, recreation, is a source of drinking water, and supports over 1200 species (see Niagara River Ecology). When something interferes with the enjoyment of a water use, it’s called a beneficial use impairment or BUI. There are 14 potential BUIs identified in the GLWQA (common to all AOCs) that the RAP Team uses to focus restoration needs, track progress and report on success. When taken together, the status of the BUIs tell us the overall condition of the Niagara River AOC.
For the Ontario side of the Niagara River, there 10 BUIs that are not impaired and 4 BUIs remaining (see below) that are still considered impaired.
- Restrictions on Fish Consumption
- Degradation of Fish & Wildlife Populations
- Degradation of Benthos
- Loss of Fish & Wildlife Habitat

What’s left to do?
The goal is to complete actions that will restore the beneficial water uses. Once the required actions are complete for an individual BUI, it is assessed against locally-defined goals. If a status assessment shows that the criteria have been met, then the RAP initiates a re-designation process by which the status of the BUI can be changed (i.e., from impaired to not impaired).
In 2021, a Niagara River Delisting Strategy was completed which will guide restoration, monitoring, and/or assessment of the remaining BUIs. The Delisting Strategy provides the most up-to-date summary of information about the Niagara River’s remaining BUIs, imparts guidance on BUI removal through the specific delisting criteria, and identifies the recommended remaining priority actions to lead organization(s) involved in the RAP for each of the remaining impaired beneficial uses.
