Season 27, Episode 13 Poisoned Waters
First Aired: April 21, 2009
A health checkup of America's waterways that uses the Chesapeake Bay and Puget Sound as examples. In both estuaries, chemicals contained in everyday consumer products can be found, and are likely affecting marine life and humans. A USGS study of the Potomac River (which feeds into the Chesapeake), for instance, revealed mutations in frogs that scientists believe are linked to chemicals found in household items; and in the Sound, orca carcasses have been found to contain high levels of PCBs.
