List of Great Lakes AOCs
Map of U.S. Great Lakes Areas of Concern
This table is sortable by AOC, state, lake, contact estimated year of management actions completed and year of AOC delisting. Estimated year of management actions completed and year of AOC delisting are a "best case scenario" projection. Some of the AOCs may proceed faster than expected, while some may experience delays due to weather, construction complications, and/or the discovery of contamination in unexpected areas.
