San Diego Accelerates Cleanup of Tijuana River Sewage Pollution
5/9/2026, 7:02:40 AM
Cross-Border Sewage Crisis
Sewage from Mexico travels the Tijuana River into south San Diego, delivering billions of gallons of contaminated water annually. The runoff fouls beaches, releases hydrogen sulfide gas, and has triggered repeated beach closures and health alerts for residents.
Funding, Legislation, and Impact Studies
The county set aside $5 million to redesign the Saturn Boulevard culvert, a hotspot that aerosolizes toxins, and is requesting $25 million from state for upgrades. Senators Steve Padilla and Catherine Blakespear introduced a bill to set health-based hydrogen sulfide thresholds by Jan 2030 and a Cal/OSHA measure to protect outdoor workers; Senate passed both, awaiting Assembly. David Alvarez proposed Proposition 4 climate-bond funds. Study found 74 % of businesses report negative impacts and half lost revenue. EPA data link pollution to lung inflammation and asthma. Study will analyze hair, blood and tissue samples; Dr. Vi Nguyen has organized a network documenting ear infections, allergic rhinitis, skin rashes, gastrointestinal issues and kidney disease among teens.
Official Statements
County officials say early-morning alerts now precede school commutes, improving child protection; YMCA of San Diego County highlighted public-health dimension and urged action; state legislators called new standards essential for safeguarding residents and outdoor workers.

On-the-Ground Actions
