Nearly $700 million in federal money since 2022 has been sent to the U.S. International Boundary and Water Commission, the national agency in charge of cross-border rivers, to upgrade deteriorating American water treatment plants near the border. … Some of the eight Democrats running for governor have visited the site in recent weeks with county officials to offer what they’d do about the millions of tons of sewage sickening thousands of residents.
