St. Louis, MO – 
Waterways in the U.S. are supposed to be fishable and swimmable.
The Clean Waters Act, passed in the 1970s, requires it. But in Missouri, the state has failed to enforce the law.
That led to a lawsuit filed by the Missouri Coalition for the Environment against the U.S. Environmental Protection Agency. Last year, they reached a settlement requiring the state to come up with new stricter water regulations.
As KWMU's Maria Hickey reports, those new rules could mean big expenses for the Metropolitan Sewer District.
