FRONTLINE "Poisoned Waters" | Sneak Peek 3 | PBS Buy the DVD: In this clip from "Poisoned Waters," correspondent Hedrick Smith investigates the alarming rate of "fish kills" in the rivers surrounding the Chesapeake Bay—hundreds of fish found floating belly-up—and genetic mutations among marine life in the area: frogs with six legs and other mutations, male amphibians with ovaries and female frogs with male genitalia. Watch on air and online beginning Tues, Apr 21 on PBS (check local listings). More than three decades after the Clean Water Act, two iconic waterways—the great coastal estuaries Puget Sound and the Chesapeake Bay—are in perilous condition. With polluted runoff still flowing in from industry, agriculture, and massive suburban development, scientists fear contamination to the food chain and drinking water for millions of people. A growing list of endangered species is also threatened in both estuaries. As a new president, Congress, and states set new agendas and spending priorities, FRONTLINE correspondent Hedrick Smith examines the rising hazards to human health and the ecosystem, and why it's so hard to keep our waters clean. Watch "Poisoned Waters" on air and online coming April 21, 2009 to PBS (check local listings).
