The Chesapeake Bay is the largest estuary in the United States. The Bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula (including the parts: the Eastern Shore of Maryland / Eastern Shore of Virginia and the state of Delaware) with its mouth of the Bay at the south end located between Cape Henry and Cape Charles.
With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the Bay's 64,299-square-mile (166,534 km2) drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) and all of Washington, D.C...https://en.wikipedia.org/wiki/Chesapeake_Bay

- Mapping the PFAS Contamination Crisis: New Data Show 2,337 Sites in 49 States, Environ. Working Group
WHY IS THIS MAP IMPORTANT?
The extent of American communities confirmed contamination with the highly toxic fluorinated compounds known as PFAS continues to grow at an alarming rate. As of January 2021, 2,337 locations in 49 states are known to have PFAS contamination.
The latest update of this interactive map documents PFAS pollution in public and private water systems. (Details about our sources and methodology are here.) Information about sites newly added to the map comes from various PFAS detections reported to government agencies in Colorado, New Hampshire, North Carolina, Ohio and other states.
