Miami may be a top tourist destination, but consuming their tap water could leave you with long-lasting effects well after your vacation is over.
The home of the Heat is just one of 43 U.S. cities—including Philadelphia and New Orleans—that has toxic “forever chemicals” in their drinking water, according to a new report.
Products such as firefighting foam and Teflon contain the PFOAs and PFOS chemicals that are contaminating water across the country. Polluted water has been linked in some cases to cancer and lower fertility and even served as inspiration for the 2019 movie Dark Waters, although much more research needs to be done into long-term harms.
Sydney Evans, Environmental Working Group study co-author, told BuzzFeed News that the research group was surprised to see chemical contamination in such a variety of cities. Out of the 44 cities tested for contaminants, only Meridian, Mississippi, passed. Perhaps unsurprisingly, the citizens of Meridian get their water from the deep depths of a 600-foot well.
While earlier studies conducted by the Environmental Protection Agency and the EWG had not shown a serious water contamination issue, Evans and her team tested for 30 different PFAS (per- and polyfluoroalkyl substances) chemicals in order to discover more information about the breadth of the contamination.
The EPA sets a safety limit of 70 parts-per-trillion limit on the two main chemicals, though some individual states have implemented stricter standards. Unfortunately, many states were found to have water with high concentrations of chemicals, including North Carolina and Iowa.
“To date, EPA has developed methods to reliably detect 29 PFAS chemicals in drinking water,” an agency spokesperson stated in an e-mail to Buzzfeed News. “Aggressively addressing PFAS will continue to be an EPA priority in 2020 and we will provide additional information on our upcoming actions as it becomes available.”
So while staying hydrated is critical, filtered water may be a better bet depending on where you live.
