VANCOUVER, British Columbia — Hazardous man-made “forever chemicals” called PFAS (per- and polyfluoroalkyl substances) are now prevalent in so many of our resources, particularly water. Thankfully, engineers from the University of British Columbia have developed a new treatment that safely removes them from drinking water for good.

“Think Brita filter, but a thousand times better,” says UBC chemical and biological engineering professor Dr. Madjid Mohseni, who developed the technology, in a university release.

There are over 4,700 PFAS in use today, and they’re common components of non-stick cookware, stain repellents, and firefighting foam. However, research continues to link them to poor health, hormone changes, heart disease, developmental delays, and even cancer. This makes it even more important to limit exposure wherever possible.

Dr. Mohseni and the team developed an adsorbing material capable of tightly trapping and containing PFAS in water before destroying them with unique electrochemical and photochemical techniques — also created by the Mohseni lab. Unlike other treatments on the market right now, this technology captures almost every particle efficiently and in a timely manner.

“Our adsorbing media captures up to 99 percent of PFAS particles and can also be regenerated and potentially reused. This means that when we scrub off the PFAS from these materials, we do not end up with more highly toxic solid waste that will be another major environmental challenge,” explains Dr. Mohseni.

Low-income areas are particularly at risk of contamination

According to the researcher, Canada no longer manufactures PFAS, but that doesn’t stop them from sneaking into various products and the environment. For instance, these chemicals can easily seep into waters when people use stain-resistant or repellent sprays and materials. PFAS also have easy access to our bodies through products like makeup and sunscreen.

Water conditions are especially important to monitor for the health of those living in lower-income areas with contaminated drinking sources. As such, the team is further narrowing their focus to benefit people in rural, remote, and Indigenous communities in Canada.

“Our adsorbing media are particularly beneficial for people living in smaller communities who lack resources to implement the most advanced and expensive solutions that could capture PFAS. These can also be used in the form of decentralized and in-home water treatments,” says Dr. Mohseni.

The UBC team looks forward to piloting their technology throughout British Columbia starting in early 2023.

“The results we obtain from these real-world field studies will allow us to further optimize the technology and have it ready as products that municipalities, industry and individuals can use to eliminate PFAS in their water,” the study author concludes.

The findings appear in the journal Chemosphere.

    Hpw can the captured chems be reused given their toxicity? And while this sounds very promising, my understanding is there is zero safe level for these particular toxins so what impact will the remaining 1% continue to have? Seems we need a way to remove 100% from water to achieve truly safe conditions. But yes, this is progress…

    Interested in buying

    I would be interested in buying a new Brita Water Filter. I wanted to however some were cost prohibited, or ones in a store like Walmart I was skeptical if this good option. So I drink bottle water. Thank you for your research and let me know when goes to public. Pam Biral

      Bottled water quality is even less regulated for pollutants than tap water. Tap water has to meet federal and EPA minimum quality guidelines. Bottled water isn’t required to meet the same standards. You’re basically rolling the dice on how much expensive a for-profit company is willing to suffer to clean your water. The answer is usually not a lot. As an example, several bottled water companies like Nestle literally put tap water into a bottle and then pack it for shipping. You would be getting the same tap water but with the yummy addition of micro-plastics

      Bottled water might be better than well water or ground water though. It’s best to get well water tested. Again you could potentially avoid a lot of micro-plastics if the well water is safe

    Congratulations Shyla – good luck in the dietetic internship.

    Getting into the thick of things is such a great education and eye opener.

    I Liked the article.. it sounds promising I hope for fast track development.

    Thanks for the insight
