The Potomac River is the primary source of drinking water in the D.C. area. Thanks to the hard work of many, the water quality of “the Nation’s River” has improved dramatically since its nadir in the 1970s, and that progress now supports revitalized waterfronts in Georgetown, Alexandria, National Harbor, and the Wharf.

However, when it rains the Potomac is still burdened with urban runoff and raw sewage overflows. To make the impact ever more real, the river has become increasingly popular as a destination for kayaking, fishing, paddle boarding, and even open water swimming.

Our guests are Mac Thornton BA '69 and JD '72 and Nancy Stoner of the Potomac Riverkeeper Network, whose mission is to “protect the public’s right to clean water in the Potomac and Shenandoah Rivers and their tributaries.” They will share both inspiring stories about what is being done to further improve the Potomac, and data that can guide us to know when it is safe to go in the water, how to avoid getting sick from exposure to polluted water, and how we can help to clean it up.

This WDCSA event is both free of charge and open to all. A zoom connection link will be sent to registrants on the day of the event.
