A new report shows farmers have made significant progress reducing sediments, pesticides and other pollutants that flow into the bay.
More than 15 million tons of sediment have been reduced annually. That's enough to fill 150,000 cars on a train that would stretch from Washington, D.C., to Albuquerque, N.M.
Delaware, Maryland, and Washington, D.C. are among the clean-up partners.
