Airing Tonight - Frontline's Poisoned Waters

More than three decades after the Clean Water Act, iconic American waterways like the Chesapeake Bay and Puget Sound are in perilous condition and facing new sources of contamination.

With polluted runoff still flowing in from industry, agriculture and massive suburban development, scientists note that many new pollutants and toxins from modern everyday life are already being found in the drinking water of millions of people across the country and pose a threat to fish, wildlife and, potentially, human health.

In FRONTLINE’s Poisoned Waters, airing Tuesday, April 21, 2009, from 9 to 11 P.M. ET on PBS (check local listings), Pulitzer Prize-winning journalist Hedrick Smith examines the growing hazards to human health and the ecosystem.
