But unfortunately, your face may be getting battered with sewage bacteria in the process. According to a new paper published in the journal [*Environmental Sciences & Technology*](), ocean spray samples from San Diego's Imperial Beach contained bacteria from sewage spillover — and those bacteria end up in the air people near the beach breathe, too. There are real health risks associated with bacteria that come from sewage runoff as they are more likely to include pathogens such as E. Coli, salmonella, and the infamous, [gastrointestinal issues-inducing norovirus](). It's still unclear, however, if bacteria found by the researchers are actually making people sick in the area. "Are they potentially infectious? Some are pathogens and some are not," Prather [told *The Guardian*](). "That’s something we’re working on now." ## Feel the Ocean To put it plainly, this stuff is pretty gross — and it may be getting into the lungs of folks who live near coastal waters, especially those who swim in them. "Once pollutants become airborne that just means so many more people can be exposed to those pollutants," explained Kim Prather, the principal investigator on the study out of UC San Diego's Scripps Institution of Oceanography, in [an interview with the city's *Union-Tribune* newspaper](). "It extends well beyond just people going to the beach or getting in the water." ## Tijuana Syndrome In their research, the team was able to link the bacteria to the Tijuana River just over the border in Mexico using air and water samples in and around the river and beach respectively. They made a shocking discovery: the river sewage runoff could account for up to a whopping 76 percent of the bacteria at Imperial Beach. While there's already an established body of work about airborne oceanic bacteria in general, this study is the first of its kind to establish a link to a known sewage source, UC San Diego professor and paper co-author Robert Knight told the *Union-Tribune*. "It was a complete shock to find how much of microbes in the air were traceable back to sewage," Knight told the newspaper. "We had no idea that effect would be so strong." With this seemingly strong link established in their research, the UCSD team plans to take DNA samples of lifeguards and surfers to see if they can gauge if there's a measurable impact to respiratory health as well. "Now that we know this is a real phenomenon," Knight added, "we need to find out what are the impacts to human health." **More on gross byproducts:** [*Residents Blame Horrid Black Fungus on Whiskey Facility*]() ## Author At Futurism, I've often been drawn to unpacking the narratives that underlie technological, scientific and medical progress, with a special interest in areas of conflict and ambiguity that end up setting agendas and steering the fates of both elites and the hoi polloi. I'm a committed generalist, but I often find myself returning to work involving NASA and the private space sector, the effects of AI on media and society, and the mechanics of the pharmaceutical industry, with a specific focus on the spread of GLP-1 drugs like Ozempic and Wegovy. Prior to Futurism, I worked for publications ranging from Media Matters and Truthdig to Raw Story and Bustle. I'm also the author of "Myspace Scene Queens," a 2024 title in Instar Books' acclaimed "Remember the Internet" series. My work at Futurism has been cited by outlets including the New Yorker, Slate, Nieman Lab, the Verge, the MIT Technology Review, the Sunday Times, and the Daily Beast. I grew up in North Carolina, attended the University of North Carolina at Asheville, and now live in Brooklyn, New York. In my free time, I'm an avid reader and music fan; you can probably find me at a local poetry reading, concert, underground rave, or DJ set. I'm the proud parent of an ineffable orange cat named Mee-Mow. ### Author social links [Bluesky]()
