Great Lakes Areas of Concern

The Areas of Concern are watersheds along the Great Lakes suffering from degraded environmental conditions stemming from historic and ongoing pollution. They were designated under the U.S.-Canada Great Lakes Water Quality Agreement based on the presence of beneficial use impairments, such as restrictions on fish and wildlife consumption, beach closures, drinking water restrictions, loss of fish and wildlife habitat, etc.

U.S. Great Lakes Areas of Concern

A total of 43 AOCs have been identified in the U.S. and Canada: 26 located entirely within the U.S.; 12 located wholly within Canada; and five that are shared by both countries. Since the inception of the AOC program, three Canadian AOCs and two U.S. AOC have been delisted. Federal, state, provincial and local partners are working to delist the other AOCs.

Remedial Action Plans (RAPs) have been developed and and are being implemented for all designated AOCs in the Great Lakes basin. RAPs were developed for each AOC to address impairments to any one of 14 beneficial uses (e.g., restrictions on fish and wildlife consumption, dredging activities, or drinking water consumption) associated with them. RAPs use an ecosystem-based, multi-media approach for assessing and remediating impaired uses. The RAP process is a model of grassroots environmental democracy, stressing empowerment of the affected public within AOCs. Successful RAPs are community driven, with active federal, state and local involvement.
