<\/p>\n\n\t\t\t\t\t\tThe smell of rotten eggs permeates Steve Egger’s Southern California home, especially at night, as the nearby Tijuana River foams up with sewage from Mexico before emptying into the Pacific Ocean.Egger, 72, says he and his wife have frequent headaches and wake up congested and coughing up phlegm. Their home is outfitted with a hospital-grade filtration system that cycles the air every 15 minutes.Despite those measures, \u201cmost nights we breathe in a horrible stench,\u201d he said. \u201cIt\u2019s awful.\u201dSince 2018, more than 100 billion gallons of raw sewage laden with industrial chemicals and trash have poured into the Tijuana River, according to the International Boundary and Water Commission. The river traverses land where three generations of the Egger family once raised dairy cows. The United States and Mexico signed an agreement last year to clean up the longstanding problem by upgrading wastewater plants to keep up with Tijuana\u2019s population growth and industrial waste from factories, many owned by U.S. companies.In the meantime, tens of thousands of people are being exposed to the sewage. Environmental Protection Agency Administrator Lee Zeldin said during a February visit to San Diego that it will take about two years to resolve one of the nation\u2019s worst and longest-running environmental crises, which affects a largely poor, Latino population.Raw sewage does not just smell bad. It emits hydrogen sulfide, a toxic gas that can erode neurons in the nose and trigger asthma attacks. It can cause headaches, nausea, delirium, tremors, cough, shortness of breath, skin and eye irritation, and even death, according to the Centers for Disease Control and Prevention. Its long-term health problems are only starting to be understood.There is no federal safety standard for hydrogen sulfide except for workers at sites where the risk is extreme, such as wastewater treatment plants or manure pits. A few states set standards decades ago, but those are outdated. A California proposal would require the state’s 56-year-old standard reflect the health risks of the gas. In Texas, lawmakers are also considering updating the state’s law.\u201cI think when you look back when the standard was first established, and then it was reviewed, it was all about nuisance \u2014 basically it was all about odor,\u201d said the California bill\u2019s author, Democratic Sen. Steve Padilla, who represents the Tijuana River Valley. \u201cI don\u2019t think we had the understanding scientifically of what the health impacts were here, and now we do.\u201dEven if the bill passes, the new standard would likely not be developed until 2030.Toxic gas from the river’s sewage infuses the airA \u201cStop the Stink\u201d sign is on Egger\u2019s fence, part of a campaign that Citizens for Coastal Conservancy launched to demand officials clean up the cross-border sewage.The 120-mile-long river starts in the Mexican city of Tijuana, crosses into California and empties into the ocean. San Diego County beaches nearby have been closed for years, and Navy SEALs who train in the water have fallen ill.Just since January, the Tijuana River has carried 10 billion gallons of mostly raw sewage and industrial waste across the U.S. border, according to International Boundary and Water Commission data. By comparison, a massive pipe that ruptured in January sent 244 million gallons of untreated sewage into the Potomac River, affecting affluent, largely white communities. That spill prompted federal intervention within weeks.In 2024, a sampling by San Diego County and the CDC representing the roughly 40,000 households close to the Tijuana River found 71% could smell sewage inside their homes and 69% had a member get sick from being exposed.Even at low levels, \u201cyou\u2019re going to feel like it\u2019s in your sinuses. You can\u2019t get rid of the smell. It\u2019s going to be a constant irritation,\u201d said Ryan Sinclair, an associate professor of environmental microbiology at Loma Linda University School of Public Health.The EPA said it is working with local and state officials to find ways to mitigate the smell.San Diego County this year distributed over 10,000 air filters to homes. But the air remains a threat. The river\u2019s foam can now be seen from space.Hydrogen sulfide levels stun researchersIn September 2024, Kimberly Prather, a chemistry professor at the University of California, San Diego, and a team of researchers installed air monitors in the neighborhood where Egger lives.What they found stunned them: The hydrogen sulfide concentrations were 4,500 times higher than typical urban levels and 150 times higher than California\u2019s air standards when river flows peaked at night.Many residents, like Egger, felt vindicated.\u201cThey\u2019d been being more or less gaslit and told, \u2018There\u2019s gas. It\u2019s a nuisance. It smells, but it\u2019s not bad,\u2019\u201d Prather said.She said her researchers have since detected thousands of other gases coming from the river that don\u2019t smell, \u201cand many of them are more toxic.\u201dDoctors recommend people moveEgger said doctors have told him to move, though they have not given him a written diagnosis of suffering from hydrogen sulfide exposure.But his family’s roots run deep. His wife grew up in Tijuana. His brother and his late brother\u2019s family live in the neighboring houses on what was Egger Dairy. Nearby are the dilapidated milk barn and rusting farm equipment.\u201cThis is where I’ve lived all my life, with my family, my parents, my grandparents,\u201d he said. \u201cThis is home.\u201dWhen Egger was a boy, he swam in the river that ran only during the rainy season. Now mostly filled with sewage and industrial waste, it goes year-round. He says the river should be restored to its historical route, which is closer to the border and farther from most residences and schools. He believes that it would not pond, creating hot spots of hydrogen sulfide gas.Less than half a mile from Egger\u2019s home, the smell is overwhelming where the river shoots out of pipes after being forced briefly underground near Saturn Boulevard.Scientists call it \u201cthe Saturn hot spot.\u201d The stench permeates passing cars with the windows up, lingering inside for days.When river flows go up, so do the number of patientsDr. Matthew Dickson and his wife, Dr. Kimberly Dickson, run a clinic about a mile from the hot spot. Many of their patients suffer from migraines, nausea, wheezing, eye infections and brain fog. Those with asthma say they use their inhalers more when the air reeks.\u201cThey’d say, \u2018You know, I feel better when it doesn\u2019t smell outside,\u2019\u201d Dr. Kimberly Dickson said.In August 2023, a tropical storm caused the river to overflow onto the streets. Within days, the doctors’ caseloads tripled.Electronic health records confirmed what the doctors suspected. When the river flows have jumped, the number of patients they have treated for respiratory problems has increased by 130%, they said.\u201cEvery day that this isn’t fixed,\u201d Dr. Matthew Dickson said, \u201cmore people are getting sick.\u201d___Pineda reported from Los Angeles.\n\t\t\t\t\t<\/p>\n
