NPR: Time to lift the ban on swimming in the Potomac and Anacostia Rivers, advocates say
A century ago, a hot summer day in D.C. would mean thousands of people crowding the banks of the Tidal Basin, the Potomac River, Anacostia River and Rock Creek to cool off. Now, environmental advocates say the waters are, in some places at least, once again clean enough to swim in. They are calling on city officials to lift the longtime ban on swimming.
