Imperial Beach marks the terminus of the [[Tijuana River Estuary|Tijuana River watershed]] and is subject to changes that occur upriver. There have been numerous instances of beach closures and pollutant [[aerosolization]] within Imperial Beach as caused by untreated sewage or spills.<ref>{{cite news |last1=Mull |first1=Jeff |title=Sewage Spill Forces Beach Closures |url=https://www.surfer.com/news/sewage-spill-forces-san-diego-beach-closures |work=Surfer |publisher=The Arena Media Brands |date=29 August 2012 |language=en}}</ref><ref>{{cite web |last1=Monroe |first1=Robert |title=Coastal Water Pollution Transfers to the Air in Sea Spray Aerosol and Reaches People on Land {{!}} Scripps Institution of Oceanography |url=https://scripps.ucsd.edu/news/coastal-water-pollution-transfers-air-sea-spray-aerosol-and-reaches-people-land |website=scripps.ucsd.edu |language=en |date=2 March 2023}}</ref><ref>{{cite news |last1=Singh |first1=Maanvi |title=Heavy metals and E coli: raw sewage at US-Mexico border a 'public health crisis' |url=https://www.theguardian.com/environment/2024/feb/15/us-mexico-california-tijuana-river-illness-public-health |work=The Guardian |date=15 February 2024}}</ref> Beaches have been closed since December 8, 2021.<ref>{{cite news |last1=Medina |first1=Madilynne |title=Coastline near San Diego closed for more than 1,000 days due to sewage crisis |url=https://www.sfgate.com/bayarea/article/coastline-near-san-diego-closed-sewage-crisis-19743214.php |access-date=10 September 2024 |publisher=Hearst Communications |date=4 September 2024}}</ref>

According to Udasin, the water quality has degraded due to five hundred illegal discharges from the South Bay plant, which has leaked a billion gallons of raw sewage flowing into the Pacific Ocean. This has been causing businesses to lose money and negatively affecting inhabitants' health. Mexico is doing a poor job maintaining sewage from the [[Tijuana River]] valley. This sewage flows across the border into Imperial Beach. Taxpayers have been pleading for action but government officials refuse proper action. Imperial Beach pollution is ruining the livelihood of Imperial Beach residents.
