These enhanced attenuation remedies replace less sustainable remedial methods like dig & haul or pump & treat, which create more PFAS waste materials.

Cost estimates are based on the required upgrades to Minnesota’s existing wastewater infrastructure to treat and destroy PFAS using current commercially available technologies and PFAS levels.

At least 45% of the nation’s tap water is estimated to have one or more types of the chemicals known as per- and polyfluorinated alkyl substances, or PFAS, according to a new study by the U.S. Geological Survey.

Accurate sampling of PFAS is vital because the data received provides insights into their potential health risks and what strategies should be used for remediation or water treatment. 

Handling or using fluorinated containers is a significant pathway for unsafe human exposure to PFOA and other PFAS. 

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.

"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.

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.

Study examines remediation at a site that began in the 1990s, with groundwater monitoring since 2000, including measuring for PFAS and PFOS since 2015.

Today’s actions represent a significant milestone for the Biden-Harris Administration’s commitments to combat PFAS pollution and safeguard drinking water.
