#Australia: Research shows #NativePlants can detox #PFAS-contaminated #water
New research from Australia's national science agency #CSIRO, the #UniversityOfSouthAustralia and the #UniversityOfWesternAustralia has found that PFAS chemicals can be removed from contaminated water using Australian plants grown in a floating #wetland.
May 4, 2022
"They’re the non-stick on #Teflon cookware, the stain resistance in #Scotchgard, and the suppression factor in #FirefightingFoam, but while the staying power of PFAS chemicals was once revered, it’s now infamous as PFAS substances continue to infiltrate the #environment and affect human health.
"Now, new research from the University of South Australia is helping to remediate the ‘indestructible’ PFASs as scientists show that Australian native plants can significantly remediate PFAS pollutants through floating wetlands to create healthier environments for all.
"Conducted in partnership with CSIRO and the University of Western Australia, the research found that PFAS chemicals (per- and poly-fluoroalkyl substances) can be removed from contaminated water via Australian #NativeRushes - #PhragmitesAustralis, #BaumeaArticulata, and #JuncusKraussii.
"Phragmites australis, otherwise known as the #CommonReed, removed legacy PFAS contaminants by 42-53 per cent from contaminated surface water (level: 10 µg/L).
"According to the US Environmental Protection Agency, exposure to PFAS may lead to a range of health issues including a decline in fertility, developmental delays in children, increased risk of some cancers, a reduced immune system, higher cholesterol, and risk of obesity.
"UniSA and CSIRO researcher Dr John Awad says that this research could alleviate many of these environmental and health risks by providing a clean, green, and cost-effective method to remove PFAS from the environment.
" 'PFASs are often referred to as ‘forever chemicals’ because they don’t break down, instead accumulating in the environment and in our bodies where they can cause adverse health effects,' Dr Awad says.
" 'In Australia, PFAS concerns often relate to the use of firefighting foam – especially legacy firefighting foam – which accumulates in the #SurfaceWater of our #waterways.
" 'Our research tested the effectiveness of Australian rushes to remove #PFASChemicals from #stormwater, finding that Phragmites australis was the most effective at absorbing chemicals through its roots and shoots.'
"The study used constructed floating wetlands as a mechanism for plants to grow #hydroponically. Dr Awad says floating wetlands present a novel and flexible way for natural #remediation systems.
" 'Constructed floating wetlands can be readily installed into existing urban environments, such as holding reservoirs and retention basins, making them highly manoeuvrable and adaptable to local waterways,' Dr Awad says.
" 'Plus, as this innovative water treatment system does not require pumping or the ongoing addition of #chemicals, it is a #CostEffective remediation system for PFAS removal.
" 'Add native plants to the mix and we have delivered a truly clean, green and environmentally-friendly method for removing toxic PFAS chemicals from contaminated water.' "
Notes to editors:
- So far, the floating wetlands system has only been examined under control laboratory conditions for PFAS remediation and the research team is looking forward to testing it in the real world, under natural conditions.
- This research is being carried out at the UniSA Mawson Lakes campus. PFAS has not been detected in or around Mawson lakes."Original press release:

#MaineCDC recommends limiting fish consumption from 4 new bodies of water due to #PFAS contamination
Maine Public | By Nora Saks
Published June 30, 2025 at 5:27 PM EDT"The Maine Center for Disease Control is recommending that people limit consuming fish from four new bodies of water due to #PFASContamination.
"The new advisories apply to game fish caught in #LovejoyPond in #AlbionME, the #SebasticookRiver in #BurnhamME and #BentonCollyerBrook in #GrayME, and #AndroscogginLake in #LeedsME and #WayneME.
"The Maine CDC issued the new guidelines after elevated levels of PFAS, the group of man-made #ForeverChemicals, were detected in fish tissue sampled by the Maine Department of Environmental Protection last year.
"In the recommendations updated last week, the Maine CDC also expanded its advisories on #AnnabessacookLake in #MonmouthME and #WinthropME, and #MessalonskeeStream in #OaklandME and #WatervilleME.
"These additions bring the total number of rivers, lakes and streams that have game fish contaminated with unsafe levels of PFAS to 25.
"For more details on the consumption limits on numbers and species of freshwater fish in each waterbody, check out the Maine CDC website."

"In 1979, an internal company report deemed #PFOS 'certainly more #toxic than anticipated' and recommended longer-term studies. That year, #3M executives flew to San Francisco to consult Harold Hodge, a respected toxicologist. They told Hodge only part of what they knew: that PFOS had sickened and even killed laboratory animals and had caused #liver abnormalities in factory workers. According to a 3M document that was marked 'CONFIDENTIAL,' Hodge urged the executives to study whether the company’s fluorochemicals caused reproductive issues or cancer. After reviewing more data, he told one of them to find out whether the chemicals were present 'in man,' and he added, 'If the levels are high and widespread and the half-life is long, we could have a serious problem.' Yet Hodge’s warning was omitted from official meeting notes, and the company’s fluorochemical production increased over time."

Toxic #Gaslighting: How #3M Executives Convinced a Scientist the #ForeverChemicals She Found in Human Blood Were Safe
Decades ago, #KrisHansen showed 3M that its #PFAS chemicals were in people’s bodies. Her bosses halted her work. As the #EPA now forces the removal of the chemicals from drinking water, she wrestles with the secrets that 3M kept from her and the world.by Sharon Lerner
May 20, 6 a.m. EDT"Kris Hansen had worked as a chemist at the 3M Corporation for about a year when her boss, an affable senior scientist named Jim Johnson, gave her a strange assignment. 3M had invented #ScotchTape and #PostIt notes; it sold everything from sandpaper to kitchen sponges. But on this day, in 1997, Johnson wanted Hansen to test human blood for chemical contamination.
"Several of 3M’s most successful products contained man-made compounds called #fluorochemicals. In a spray called #Scotchgard, fluorochemicals protected leather and fabric from stains. In a coating known as #Scotchban, they prevented food packaging from getting soggy. In a soapy foam used by #firefighters, they helped extinguish jet-fuel fires.
"Johnson explained to Hansen that one of the company’s fluorochemicals, #PFOS — short for perfluorooctanesulfonic acid — often found its way into the bodies of 3M factory workers. Although he said that they were unharmed, he had recently hired an outside lab to measure the levels in their blood. The lab had just reported something odd, however. For the sake of comparison, it had tested blood samples from the American Red Cross, which came from the general population and should have been free of fluorochemicals. Instead, it kept finding a contaminant in the blood.
"Johnson asked Hansen to figure out whether the lab had made a mistake. Detecting trace levels of chemicals was her specialty: She had recently written a doctoral dissertation about tiny particles in the atmosphere. Hansen’s team of lab technicians and junior scientists fetched a blood sample from a lab-supply company and prepped it for analysis. Then Hansen switched on an oven-size box known as a mass spectrometer, which weighs molecules so that scientists can identify them.
"As the lab equipment hummed around her, Hansen loaded a sample into the machine. A graph appeared on the mass spectrometer’s display; it suggested that there was a compound in the blood that could be PFOS. That’s weird, Hansen thought. Why would a chemical produced by 3M show up in people who had never worked for the company?"
