Blog: San Diego has a cross border sewage problem
For decades, raw sewage from Tijuana, Mexico has, and continues, to flow across the border into San Diego, California. This discharge flows into the Tijuana River Valley, and ultimately to the Pacific Ocean. This pollution has negatively impacted the Tijuana River Valley and the Tijuana River Estuary, one of the last remaining estuaries in California, and the beaches. Unhealthy concentrations of fecal indicator bacteria has forced the County of San Diego to close 10 miles of beach access from the US-Mexico Border all the way to the beaches of Coronado. At the urging of Congressman Scott Peters, the San Diego State University School of Public Health issued a white paper which details the public health risks posed by the transborder flow of sewage.
