The Sleep Crisis Linked to Toxic 'Forever Chemicals'
Toxic "forever chemicals," known as per- and polyfluoroalkyl substances (PFAS), pose significant environmental and health risks. A recent study reveals a concerning link between elevated PFAS levels in the bloodstream and poor sleep quality. These chemicals, effective in repelling water, oil, and heat, are commonly found in products like waterproof clothing and non-stick cookware. However, their stability in the environment results in their accumulation in human bodies, where they have been associated with serious health issues, including diabetes, cancers, and immune system disruptions.
In this study conducted by researchers at the University of Southern California, blood samples from 144 participants aged 19 to 24 were analyzed for seven types of PFAS. The findings indicated that higher levels of PFDA, PFHxS, and PFOA were significantly linked to shorter sleep duration, with affected individuals reportedly sleeping around 80 minutes less. This research adds to the growing evidence of the negative impact PFAS have on health, highlighting the urgent need for addressing these persistent contaminants.

Puraffinity is pleased to announce that its G400+ adsorbent media has been certified to NSF/ANSI/CAN 61 and NSF/ANSI/CAN 372 standards for Point of Entry (POE) and Water Treatment Plant End Use applications The certifications confirm that G400+ meets the required health effects criteria for materials used in drinking water system components. This milestone enables Puraffinity to support installations where NSF-certified products are required, including municipal drinking water applications. “As a member of the American Water Works Association (AWWA), I see this certification as an important step for broader municipal adoption, ” said Neal Megonnell, Chief Commercial Officer at Puraffinity. “It enables utilities to deploy our technology where NSF compliance is required, and it strengthens our ability to scale PFAS treatment solutions while maintaining the highest standards of safety and performance.” Designed for highly effective PFAS removal with rapid kinetics, the advanced adsorbent media G400+ supports compact system design and efficient treatment across a wide range of water matrices. Building on this milestone, the company continues to advance water treatment solutions that help utilities and industry address PFAS compliance and protect drinking water quality.
Puraffinity partners with the U.S. Army ERDC to evaluate Puratech G400, an advanced adsorbent for PFAS removal, through lab and field trials comparing its performance and cost-effectiveness to existing PFAS treatment technologies
Puraffinity signs first commercial agreement for full-scale deployment of its PFAS removal technology
An exclusive panel featuring Puraffinity CEO Vincent Caillaud, who will join industry leaders to discuss cutting-edge solutions for combatting PFAS, “forever chemicals”, in drinking water. With PFAS contamination presenting urgent health challenges due to their extreme persistence, mobility, and health impacts at trace levels, this session will spotlight the realities of PFAS in water supplies, the latest science driving regulatory change, and the next generation of removal technologies.
