#PFAS remediation

[thoughtlessarse]

Per-and poly-fluoroalkyl substances (PFAS) are known as "forever chemicals" because they are notoriously resistant to degradation. Due to their stable chemical structure, PFAS—which are found in thousands of variants—are used in oil and grease-resistant food packaging, non-stick cookware, cosmetics, clothing, and fire-fighting foams. The chemicals are so widespread that they have infiltrated water sources and soil. In fact, recent reports have found that much of our global water resources exceed the drinking limits of PFAS and concerns over their environmental and health impacts have steadily escalated. Despite ongoing efforts to develop ways of degrading PFAS, current methods are limited by a lack of efficient, scalable and environmentally friendly processes. Now, a team of scientists from UNSW's School of Chemistry have designed a catalyst system that can activate a reaction to break down common types of branched PFAS. The new method, developed by Dr. Jun Sun and Professor Naresh Kumar and recently published in the journal Water Research, holds promise for more efficient and sustainable PFAS remediation in the future. Working alongside Prof Denis O'Carroll, Prof Michael Manefield and Dr. Matthew Lee from the UNSW School of Civil and Environmental Engineering, the team have designed a catalyst system that could play a key role in solving the problem of PFAS.

Scientists from the University of Rochester have developed new electrochemical approaches to clean up pollution from "forever chemicals" found in clothing, food packaging, firefighting foams, and a wide array of other products. A new Journal of Catalysis study describes nanocatalysts developed to remediate per- and polyfluoroalkyl substances known as PFAS. The researchers, led by assistant professor of chemical engineering Astrid Müller, focused on a specific type of PFAS called Perfluorooctane sulfonate (PFOS), which was once widely used for stain-resistant products but is now banned in much of the world for its harm to human and animal health. PFOS is still widespread and persistent in the environment despite being phased out by US manufacturers in the early 2000s, continuing to show up in water supplies.

It’s quite exciting to be working in environmental remediation when the EPA has just set maximum contaminant levels for these 6 PFAS compounds, which is the first time they’ve set new MCLs in quite a while. So I’ve been in a million meetings mentioning PFAS and “PFAS has taken over LinkedIn feeds!!!” was an actual bullet point in a PowerPoint today

The Associated Press: 22 attorneys general oppose 3M settlement over water systems contamination with 'forever chemicals'

TRAVERSE CITY, Mich. (AP) — Twenty-two attorneys general urged a federal court Wednesday to reject a proposed $10.3 billion settlement over contamination of U.S. public drinking water systems with potentially dangerous chemicals, saying it lets manufacturer 3M Co. off too easily.

The deal announced in June doesn’t give individual water suppliers enough time to determine how much money they would get and whether it would cover their costs of removing the compounds known collectively as PFAS, said the officials with 19 states, Washington, D.C., and two territories. In some cases the agreement could shift liability from the company to providers, they said.

“While I appreciate the effort that went into it, the proposed settlement in its current form does not adequately account for the pernicious damage that 3M has done in so many of our communities,” said California Attorney General Rob Bonta, leader of the multistate coalition.

3M spokesman Sean Lynch said the agreement “will benefit U.S.-based public water systems nationwide that provide drinking water to a vast majority of Americans” without further litigation.

“It is not unusual for there to be objections regarding significant settlement agreements,” Lynch said. “We will continue to work cooperatively to address questions about the terms of the resolution.”

The company, based in St. Paul, Minnesota, manufactures per- and polyfluorinated substances — a broad class of chemicals used in nonstick, water- and grease-resistant products such as clothing and cookware, as well as some firefighting foams.

Described as “forever chemicals” because they don’t degrade naturally in the environment, PFAS have been linked to a variety of health problems, including liver and immune-system damage and some cancers.

3M has said it plans to stop making them by the end of 2025.

Some 300 communities have sued 3M and other companies over water pollution from the compounds. A number of states, airports, firefighter training facilities and private well owners also have pending cases.

They have been consolidated in U.S. District Court in Charleston, South Carolina, where the proposed settlement was filed last month.

Although the company put its value at $10.3 billion, an attorney for the water providers said it could reach as high as $12.5 billion, depending on how many detect PFAS during testing the Environmental Protection Agency has ordered over the next three years.

The law firm representing the water providers did not immediately respond Wednesday to messages seeking comment.

EPA in March proposed strict limits on two common types, PFOA and PFOS, and said it wanted to regulate four others.

In addition to California, states urging Judge Richard Gergel to reject the deal included Arizona, Colorado, Connecticut, Hawaii, Maine, Maryland, Massachusetts, Minnesota, New Hampshire, New Jersey, New Mexico, New York, Pennsylvania, Rhode Island, Tennessee, Texas, Vermont and Wisconsin. Also opposed were Washington, D.C., Puerto Rico and the Northern Mariana Islands.

In a court filing, the attorneys general said it would force nearly all public water providers nationwide to participate unless they withdraw individually — even those that haven’t filed suits or tested for PFAS.

“Troublingly, they would have to make their opt-out decisions without knowing how much they would actually receive and, in many cases, before knowing the extent of contamination in their water supplies and the cost of remediating it,” the officials said in a statement.

A provision in the proposed deal would shift liability from 3M to water suppliers that don’t opt out, the statement said. That could enable the company to seek compensation from providers if sued over cancer or other illnesses in PFAS-affected communities, it said.

“As such, the proposed settlement is worth far less than the advertised $10.5 billion to $12.5 billion,” the attorneys general said.

The attorneys general did not take a position on a separate $1.18 billion deal to resolve PFAS complaints against DuPont de Nemours Inc. and spinoffs Chemours Co. and Corteva Inc.
