Decision delayed on dangerous chemical in drinking water: part 2 of Erin Brockovich's real-life unhappy ending

Following up on a previous Boing Boing post by Miles O'Brien on the real-life unhappy ending to "Erin Brockovich," here's part 2 of the PBS NewsHour story.

Miles talks to scientists, members of the chemical industry and representatives from Pacific Gas and Electric about chromium-6 contamination in American drinking water. What is a safe level for humans to consume and why has the EPA stalled on setting a federal standard?

Below, a Flickr slide show with stills shot by Miles during the shoot in Hinkley, California, where the story takes place.
