Yesterday, frustration in Nestor boiled over as residents and community leaders pressed county officials about the long-running Tijuana River Valley sewage crisis. Neighbors described a constant rotten-egg stench, foamy river water and headaches they link to polluted flows crossing the border. County staff and engineers zeroed in on site-specific, short-term fixes, even as they acknowledged that big-picture, binational infrastructure work is still the only real long-term solution.
According to CBS 8, the ad hoc subcommittee met in Nestor and is drafting a formal letter that advocates hope will push state and federal leaders to declare a state of emergency and move faster on immediate relief. Community speakers urged officials to speed up work that could cut daily flows of untreated wastewater near their homes.
Saturn Boulevard hot spot and near-term fixes
Regional engineering work has flagged the Saturn Boulevard culverts in Nestor as a pollution hot spot, a stretch where a six-foot drop and churning water create foam and aerosolized contaminants. The San Diego Regional Water Board’s executive officer report notes an $8.75 million county allocation, including $2.5 million for a temporary submerged pipe extension at Saturn Boulevard. A January feasibility study outlines options, such as HDPE pipe extensions and channel modifications, to reduce turbulence and foaming.
The feasibility analysis details how extending a discharge pipe below the water surface, or regrading a pilot channel, could blunt the small waterfall effect that researchers say boosts airborne pollution. That change is intended to lower the chance that contaminated droplets get kicked up into the air. The technical memo lays out pros and cons for these short-term tweaks, along with bigger channel reconfigurations that would need more money and floodplain review.
Research ties river pollution to airborne toxins
Peer-reviewed work from UC San Diego and partner institutions has linked the foamy, turbulent stretch of river near Saturn Boulevard to spikes of hydrogen sulfide and hundreds of other gases, backing up residents’ complaints about the smell and irritation. A Scripps Institution of Oceanography summary of that research, together with coverage in the Los Angeles Times, describes readings that in some locations exceeded state one-hour thresholds and raise concerns about what chronic exposure could mean for children and older adults.
Advocates push for pilot channels and temporary reroutes
At the Nestor meeting, residents and advocates called for a mix of pilot projects, including cleaning and maintaining a pilot channel, temporarily rerouting flow into a historical channel and targeted pipe work designed to move polluted water away from homes and cut down on stagnant contaminated pools. Leon Benham told CBS 8 the planned work would “mirror standard flood-control maintenance performed on other waterways,” language that tracks with the regrading and outfall-modification strategies engineers have already evaluated.
Binational projects are rolling but do not erase near-term needs
The United States and Mexico signed a memorandum in July 2025, followed by Minute 333, to speed up border-area infrastructure projects, and the EPA reports that several upgrades on both sides of the border are underway that should eventually cut millions of gallons per day of transboundary sewage. Public EPA updates describe these as essential projects that take time to build, while local leaders argue that neighborhood-level fixes and health monitoring have to move forward in parallel…
