New technology seeks to destroy toxic “forever chemicals” in drinking water


Grand Rapids, Michigan — Scientists estimate far more than 200 million Americans in all 50 states could have most cancers-producing carcinogens in their consuming drinking water. The poisonous chemicals for every- and polyfluoroalkyl substances, known as PFAS, have been practically indestructible — but new know-how aims to modify that. 

Sandy Wynn-Stelt identified way too late that her Michigan dwelling sat across from a previous squander dump. Her spouse died of most cancers 6 yrs in the past and she has had thyroid most cancers. For additional than 20 yrs, they drank very well drinking water contaminated with PFAS.

“You cannot see it. You cannot flavor it. You cannot odor it. You will not know it really is there unless you test for it,” Wynn-Stelt explained to CBS News. 

PFAS — guy-designed, virtually indestructible chemicals — grew to become commonly employed for their potential to resist oil and water. They have been observed in some firefighting foamscosmetics and non-stick cookware, between other solutions. Because the chemical compounds will not crack down in the atmosphere, they can contaminate soil and consuming drinking water sources, wherever they can accumulate and ultimately make their way up the food chain.

At least 2,854 destinations in 50 states and two territories are now regarded to be contaminated with the chemicals, according to the Environmental Doing the job Team

“The danger is authentic,” reported Amy Dindal, PFAS software supervisor for Battelle, a scientific nonprofit that has designed promising technologies to eradicate the dilemma. Battelle employs a system termed supercritical h2o oxidation to break down the chemical bonds in just seconds.

“‘Supercritical water’ usually means that you increase the temperature and improve the strain and you get it into a specific state, wherever the oxidation will manifest more in a natural way. So in this unique point out, it breaks the [carbon–fluorine] bond,” Dindal told CBS Information. 

Battelle stated it has correctly utilised the process in its labs to essentially annihilate PFAS in ingesting h2o and has begun partnering with the squander management business Heritage Crystal-Clean for added tests.

“I totally think it truly is an answer that no person has experienced prior to,” Brian Recatto, CEO of Heritage Crystal-Clean up, advised CBS News. “We are hoping to have a scalable edition of the plant within just 6 to 8 months.” 

CBS News had distinctive obtain to the initially demonstration of the know-how, in which h2o containing PFAS was taken care of at a wastewater treatment method plant. Heritage Crystal-Thoroughly clean has a number of services all-around the place the place it hopes to use the technology to handle wastewater.

A attainable resolution can’t come before long plenty of for Wynn-Stelt, who is also a member of the advocacy group Good Lakes PFAS Motion Network.

“It would be these kinds of a video game-changer if we could do this,” she mentioned. “It is heading to be the only way that we can keep this out of our waters, out of our streams, out of our food stuff.”
