Continue working with Mexican counterparts to address the causes of Tijuana River Valley pollution.

While we continue to work with our Mexican counterparts to address the causes of the pollution

Vargas and other San Diego lawmakers said they would continue working with Mexican counterparts to address the underlying causes of Tijuana River pollution.

The official House homepage listed: “Reps. Vargas, Peters, Levin, Jacobs Call on SBA for Support for Local Businesses Impacted by Tijuana River Pollution,” saying Vargas and colleagues called on SBA to provide continued support for small businesses impacted by pollution in the Tijuana River Valley.

In the lookback window, Vargas was still taking official action tied to the Tijuana River pollution crisis, though this item targets business impacts rather than the Mexican-side pollution causes directly.

AP reported that since 2018 more than 100 billion gallons of raw sewage, industrial chemicals, and trash have entered the Tijuana River; the United States and Mexico signed an agreement in 2025 to upgrade wastewater plants, but officials said a full fix would take years and more federal support was needed.

Latest-window reporting shows the problem remains unresolved, but also confirms ongoing U.S.-Mexico infrastructure cooperation on the causes of the pollution.

Vargas announced he was leading a FY2027 request for $100 million for the U.S.-Mexico Border Water Infrastructure Program, which can fund projects to combat cross-border pollution including the Tijuana River Valley; his office said the San Diego delegation had secured over $650 million for pollution response and South Bay International Wastewater Treatment Plant upgrades.

This is concrete federal action by Vargas to continue funding cross-border water infrastructure aimed at the pollution source and related wastewater capacity.

IBWC lists Minute 333, signed in Tijuana and approved by both the United States and Mexico on December 15, 2025, as “Comprehensive actions to address the border sanitation problem at San Diego, California - Tijuana, Baja California.”

Official binational action after Vargas’s continued advocacy shows U.S. and Mexican counterparts adopted a new sanitation framework for the exact cross-border pollution problem.

USIBWC said the South Bay plant expansion would double capacity, was aimed at drastically reducing transboundary sewage flows from Baja California, and would work with Mexico’s sanitation improvements under Minute 328 to eliminate up to 90% of untreated wastewater reaching the coast. The release quoted Vargas saying the San Diego delegation secured $400 million and would continue addressing Tijuana River Valley sewage pollution using all available avenues.

This directly connects Vargas’s funding work with a U.S.-Mexico wastewater solution addressing causes of the Tijuana River Valley pollution.

Official implementation evidence shows the binational infrastructure plan moved from agreement toward construction, supporting at least partial delivery of the commitment to keep working on root causes.
