Hundreds of millions of dollars in federal funds to conserve water in the Colorado River Basin — including $86.6 million for advanced wastewater treatment in Tucson — have been frozen by the Trump administration, Arizona’s senators say. U.S. Sen. Mark Kelly’s office said funding for all projects related to the river that were to be financed by the 2022 Inflation Reduction Act — which include the Tucson project — are frozen. Specifically, the Tucson project to treat wastewater to drinking-water standards is on a federal website’s list of frozen projects, said David Wegner, a retired U.S. Bureau of Reclamation official.
