The US Environmental Protection Agency (EPA) has revealed that around 26 million Americans are exposed to per- and polyfluoroalkyl substances (PFAS), toxic forever chemicals, in their drinking water. A report by the Environmental Working Group (EWG) disclosed that the EPA’s testing rule detected PFAS in 431 water systems above set limits. This aligns with a previous 2020 EWG study estimating over 200 million Americans might be affected. PFAS contamination is now evident in over 2,800 locations nationwide. The chemicals, found in blood samples of 99% of Americans, pose cancer, developmental, and vaccine efficacy risks. Calls for stricter regulation and industrial control persist.
Prelims pointer
- Per- and Polyfluoroalkyl Substances (PFAS): A group of synthetic chemicals used in various products due to their water- and grease-resistant properties. PFAS are associated with health and environmental concerns, and their presence in drinking water raises widespread health alarms.
- Environmental Protection Agency (EPA): A US government agency responsible for safeguarding human health and the environment. It establishes regulations to control pollution, including water quality.
- Environmental Working Group (EWG): A nonprofit organization focusing on public health and environmental issues. Their research and advocacy highlight the impact of various pollutants on society.
- Industrial Polluters: Industries that release harmful chemicals into the environment, including water sources. The EWG’s estimation of 30,000 such polluters underscores the magnitude of the issue and the need for better regulation.
- Centers for Disease Control and Prevention (CDC): A national public health agency in the US that conducts research and provides health information. Their detection of PFAS in almost all Americans’ blood highlights the extensive exposure to these chemicals.
