US EditionHuman Exposure to per- and Polyfluoroalkyl Substances and Other Emerging Contaminants in Drinking Water
- Researchers at Stevens Institute of Technology published a March 2025 study showing iron powder removes PFOS from water more effectively than activated carbon.
- PFOS, a persistent chemical widely used in products like non-stick cookware and firefighting foam, contaminates soil and water globally due to its resistance to degradation.
- The study found iron powder 26 times more effective per surface area than activated carbon and maintained performance even after rusting, suggesting an oxidized surface aids removal.
- Co-Author Heather Stapleton emphasized that regularly checking for pollutants in our drinking water is crucial, pointing to a need for improved treatment methods.
- This discovery could lead to scalable, cost-effective water purification methods that address the urgent public health threat posed by persistent PFOS contamination.

Human exposure to per- and polyfluoroalkyl substances and other emerging contaminants in drinking water
A wide range of chemicals was measured in different types of drinking water and urine samples through target and non-target screening (NTS) to estimate human exposure. Tap water samples collected from 42 locations in Barcelona (August–October/2020, May/2021), tap water filtered with domestic activated carbon filters (AC, N = 6) and reverse osmosis (RO, N = 5), commercial bottled water (N = 10), and urine (N = 39) samples were included. 35 per- a…
Study uncovers disturbing phenomenon years after residents stopped drinking local water: 'Likely, this city is not alone'
Exposure to per- and polyfluoroalkyl substances in drinking water has lasting long-term effects for residents, according to a new study by researchers at Michigan State University. What's happening? PFAS are synthetic chemicals used in hundreds of everyday products because they repel heat, grease, and water. They've been around for decades, but research into their harmful effects when they contaminate food and water sources is a new field of st…
Bill would cover 'Forever Chemical' exposure at bases under VA benefits
A bipartisan bill would allow veterans with health issues caused by exposure to “forever chemicals” at U.S. military bases to be treated as service-connected disabilities, which would further open the door to health care and benefits compensation for those impacted. Forever chemicals, more technically known as polyfluoroalkyl substances, or PFAS, are long-lasting chemicals that break down slowly. They are found in many everyday objects, food, an…
Per- and polyfluoroalkyl substances (PFAS) in United States tapwater: Comparison of underserved private-well and public-supply exposures and associated health implications
Drinking-water quality is a rising concern in the United States (US), emphasizing the need to broadly assess exposures and potential health effects at…
