Tijuana River Valley residents are once again forced to endure noxious odors wafting from massive wastewater dumping, prompting health guidance from San Diego County officials. In a bid to put an end to this long-standing issue, County Supervisor Jim Desmond has urged the federal government to impose penalties on Mexico if it continues to release hundreds of millions of gallons of raw sewage into US waters.
Desmond’s call comes after reports of higher-than-normal hydrogen sulfide readings from the Tijuana River. The San Diego County Air Pollution Control District linked these findings to alleged infrastructure work in Mexico, which has led to up to 5 million gallons per night of sewage entering the Tijuana River Valley.
The supervisor took a firm stance on the issue, suggesting that restrictions be placed on the flow of potable water to Tijuana and possible limitations on cross-border travel between Mexico and the US. “It’s clear that Mexico will not act unless real pressure is applied,” Desmond said. “This is a national security issue and a public health crisis.”
Residents near the affected areas have been advised by county public health officials to limit outdoor activities, keep doors closed, and use indoor fans and air purifiers to improve air circulation.
In response to concerns about the air quality, free air purifiers are available for residents in ZIP codes 91932, 92154, and 92173. These areas include Imperial Beach, San Ysidro, Nestor, and other South Bay neighborhoods.
Dr. Ankita Kadakia, San Diego County’s interim public health officer, emphasized the need for individuals to be aware of their surroundings and take necessary precautions when faced with strong odors. People with pre-existing respiratory conditions are advised to have emergency medications readily available and seek medical attention if symptoms persist or worsen.
The release of wastewater into US waters is a long-standing issue that has been investigated by the International Boundary and Water Commission (IBWC) in collaboration with its partners in Mexico. The IBWC operates the South Bay International Wastewater Treatment Plant and works to address border water issues.
As the situation continues, county officials are urging federal authorities to work closely with their Mexican counterparts to stop the flow of raw sewage and bring a resolution to this persistent source of pollution. In the meantime, residents near the Tijuana River Valley will have to endure the toxic fumes until an effective solution is implemented.
