For the first time, a national conservation group is declaring the Chicago River one of America's most endangered waterways.

American Rivers is adding the Chicago River to its annual list of threatened waterways to people and wildlife.

Last week, the EPA ordered Illinois officials to adopt more stringent water-quality standards to make stretches of the Chicago River, Cal-Sag Channel and Little Calumet River safer for recreation.

The cleanup is estimated to cost $72 million for new germ-killing equipment and another $355 million for deep tunnel sewer pipes to store waste and storm runoff.
