There was a time when the water of Chesapeake Bay would appear to boil, but it was actually millions of oysters ejecting filtered water. The bay’s waters, the old timers tell us, were crystal clear. But agricultural run-off and untreated wastewater flowed into the Chesapeake for years, fouling the water and making our nation’s largest estuary a shadow of its former self.
In 2009, the U.S. Environmental Protection Agency (EPA) organized the cleanup efforts of six states within the bay’s watershed, including Maryland, Virginia, Delaware, Pennsylvania, New York, West Virginia and the District of Columbia. The efforts to limit pollution going into the bay included improving municipal wastewater treatment systems (known as point source pollution) and reducing agricultural runoff (known as nonpoint source pollution). Plans were in place, actions were being taken, and traction was being made.
