Baja California Gov. Jaime Bonilla is involved in a war of words with a California mayor over cleanup efforts along the Tijuana River Valley, which lies between Tijuana and the city of San Diego.

For decades, raw sewage, trash and debris have flowed from south of the border into the U.S.

Most of those materials, especially the raw sewage, end up in the Pacific Ocean, forcing the closure of beaches in cities like Imperial Beach where over the last nine months, beaches have been closed 180 days due to high bacteria levels in the ocean water.
