The United States government has announced a strong commitment to address the cross-border pollution of the Tijuana River, which has discharged untreated wastewater and industrial waste into communities in southern San Diego County, impacting beaches, air quality, and public health in the region.
The federal administration has pledged more than $667 million to clean up and modernize wastewater infrastructure, aiming to significantly reduce harmful flows reaching United States territory. This investment adds to binational agreements and pilot projects designed to intercept trash and improve water quality.

However, local leaders and California lawmakers have expressed concerns that the state must also step up its efforts to tackle a long-standing environmental problem that has caused repeated beach closures and health complaints among residents due to pollution.
What is needed for the cleanup to be effective?
In addition to federal funding, experts say California must strengthen environmental regulations, update air quality standards, and coordinate actions with Mexico to address both water contamination and harmful gases affecting nearby communities.
