Last night, Tuesday, April 21st, on PBS Frontline, journalist Hedrick Smith hosted his two-hour production titled "Poisoned Waters." Most of the footage and interviews concerned the watersheds of Chesapeake Bay and Puget Sound.

The DVD can be purchased for $25 at pbs.org. I recommend earth people see it.
