We are senior Chesapeake Bay scientists and policymakers from Maryland, Virginia and Pennsylvania who have concluded that after decades of effort, the voluntary, collaborative approach to restoring the health and vitality of the largest estuary in the United States has not worked and, in fact, is failing. Our group unanimously recommends that all states draining into the Chesapeake Bay adopt our 25 action items in their Watershed Implementation Plans (WIP) and implement them to improve the Bay’s water quality and to meet the requirements of the Clean Water Act.
