Summary of the matter addressed in the submission:

The Submitter asserts that Mexico is failing to effectively enforce its environmental laws relating to wastewater management, public health, transboundary notification procedures through binational channels, and overall management of the water resource, leading to what the Submitter refers to as a transboundary sewage crisis in the area.

The Submitter asserts that inadequate wastewater infrastructure and intentional discharges of millions of gallons of raw sewage each day are contributing to the rapid deterioration of the Tijuana River Valley ecosystems and adjacent coastal areas in California, US. The Submitter adds that Mexico is failing to conduct investigations, issue sanctions or closure orders, require remedial measures and infrastructure improvements, as well as initiate legal proceedings against violators to prevent further environmental damage.

The Submitter adds that Mexico’s inadequate wastewater infrastructure and management is forcing people to live and work near open sewage and exposing local populations to toxic chemicals and dangerous pathogens, causing serious harm to public health and the environment. According to the Submitter, continuous sewage discharge into the Tijuana River which flows into the United States, constitutes a severe transboundary environmental hazard.
