The U.S. Senate agriculture committee heard testimony today on the Environmental Protection Agency’s proposed Waters of the U.S. (WOTUS) rule.

Nearly a year ago, the EPA proposed a change to the Clean Water Act that it says would clarify its authority over certain wetlands and streams. But Iowa Republican Senator Chuck Grassley, who serves on the agriculture committee, says the proposal has met strong opposition in farm country.

The board of the state's largest water utility has voted unanimously to sue three northern Iowa counties, holding them responsible for the high nitrate levels in rivers the utility uses for source water. Des Moines Water Works CEO and General Manager Bill Stowe says there have been significant peaks in nitrate levels throughout the last three years.
