The new administrator of the U.S. Environmental Protection Agency has seemingly responded to Imperial Beach Mayor Paloma Aguirre’s letter urging federal action on the Tijuana River sewage crisis impacting southern San Diego County. Lee Zeldin, the 17th administrator of the Environmental Protection Agency (EPA) since January 29, 2025, posted on X Saturday evening that he was recently briefed on the large amounts of raw sewage flowing into the U.S. from Mexico, which is impacting the water and air quality for residents in San Diego’s South Bay.
