Niagara River Area of Concern

The Niagara River was designated as one of the 43 Areas of Concern in accordance with Great Lakes Water Quality Agreement (GLWQA). Remedial Action Plan (RAP) is an ongoing collaborative effort implemented by federal, provincial, and local governments as well as industry and public partners. There are 3 key stages of the RAP: Stage 1 is a detailed description of the environmental problem; Stage 2 identifies remedial actions and options; Stage 3 is the final document providing evidence that the beneficial uses have been restored and the AOC can be “delisted”.

The Niagara River is a 58-km waterway connecting Lake Erie and Lake Ontario. The Canadian section of the Niagara River Area of Concern extends along the entire length of the Canadian side of the Niagara River, and includes the Canadian side of Niagara Falls and the Welland River watershed.
