The primary Senate sponsors of S.B.543 are Oregon State Senators Janeen Sollman and Michael Dembrow. The primary House sponsors are Oregon State Representatives Maxine Dexter and Tom Andersen. 

In Situ Remediation Services Ltd. (IRSL), a leading environmental remediation company based in Canada, has recently completed a pilot study demonstrating how PFAS are effectively treated in the capillary fringe of an AFFF source zone by in situ injection using Colloidal Activated Carbon (CAC).

Webinar: PFAS destruction products are increasingly commercially available, with technologies like Aquagga’s hydrothermal alkaline treatment, or HALT, and Regenesis’s PlumeStop, an in-situ colloidal activated carbon, or CAC.

Despite a massive focus on PFAS substances and pesticide residues in Danish drinking water, little attention is paid to the hundreds of other chemical compounds in our groundwater.

This request for input follows EPA’s September 2022 proposed rule to designate two PFAS as hazardous substances under CERCLA.

Aquagga, Inc., a Tacoma, Washington-based Public Benefit Corporation, has entered into an exclusive licensing agreement with Mines for the commercialization of the HALT-PFAS technology.

"They're saying, 'Hey, doctors, if you're treating patients who live in PFAS-contaminated areas, you need to do more for these patients,'" said Jamie DeWitt, an immunotoxicologist at East Carolina University.

Inside E. coli bacteria, researchers have found an enzyme, C-P lyase, that enables the microbe to degrade highly stable chemicals.

Fibre-based moulded bowls, which are marketed as “compostable,” had PFAS levels three to 10 times higher than doughnut and pastry bags. PFAS are added to these bowls and bags as a water- and grease-repellent.

Activated carbon is a charcoal-like substance that PFAS stick to quite well and can be used to remove PFAS from water. Ion exchange systems are typically even better, writes Joe Charbonnet.
