Potomac River



The IAHS field trip Water Quality Issues on the Potomac River went to Washington, D.C., area May 14 to see the river and the Blue Plains Sewage Treatment Plant.

The Potomac River is the second largest tributary entering the Chesapeake Bay. It is under tidal influence below the fall line, a short distance upstream from Washington, D.C. Extensive cleanup activities have been underway for more than 10 years in an effort to improve the historically degraded water quality of the river. Among other things, the cleanup has led to a dramatic resurgence of aquatic plant growth during the past 5 years, which some view as a problem.
