Tijuana River Pollution

Updates Related to the Tijuana River Pollution 

Transboundary pollution flowing from Mexico into the Tijuana River or coastal tributaries create severe impacts to water quality, public health, and environment of San Diego border region. Pollutants that are not captured in Mexico are frequently carried by stormwater runoff or fugitive wastewater from areas in the City of Tijuana across the border and into natural areas in the U.S., including important ecological sites such as the Tijuana River National Estuarine Reserve and Border Field State Park. Contaminated flows in the Tijuana River can reach upwards of hundreds of millions of gallons per day during severe events. To learn on the most recent developments please see list below.
