The Pfas Problem on Fair Isle Fair Isle, Britain's most remote inhabited island, has been found to have the highest levels of toxic Pfas in its drinking water in Scotland. The island, known for its knitting and rare birds, has no obvious industrial sources of the chemicals, but scientists believe that seaspray and foam might be the culprit. How Pfas Are Transported to Fair Isle Pfas, or "forever chemicals," are highly surface-active and can be attracted to the interface between water and air. This allows them to be transported through seawater and accumulate in seafoam and seaspray. According to Bo Sha, an environmental chemist at Stockholm University, once airborne in bubbles or spray, the chemicals can travel hundreds of kilometers in days. The Impact of Pfas on Fair Isle The presence of Pfas on Fair Isle has raised concerns among residents and scientists. While all Scotland's public drinking water remains below official Pfas thresholds for safe consumption, the data from Fair Isle and other coastal areas represents an alarming indication of the accumulation of these chemicals in the environment. Kathy Coull, a traditional knitter and textile-maker on the island, has been filtering her water each night since Pfas results were first published in 2024 and is calling for Scottish Water to do more to address the pollution. The Bigger Picture Fair Isle is not unique in its Pfas problem. Across Scotland, remote lochs from Orkney to the Western Isles would fail a proposed EU threshold for safe environmental levels of Pfas. The issue highlights the need for better monitoring and regulation of these chemicals, which can have significant impacts on human health and the environment. The Future of Pfas Monitoring The discovery of Pfas on Fair Isle and other remote coastal areas underscores the need for more effective monitoring and regulation of these chemicals. As scientists continue to study the movement and accumulation of Pfas in the environment, it is clear that a more comprehensive approach is needed to address this growing environmental concern.

The Discovery of PFAS in the Solent Strait Scientists have found high levels of toxic PFAS, or “forever chemicals”, in soil, water and throughout the marine food chain in the UK’s Solent strait, including at protected environmental sites, according to a new study. Extent of the Pollution In some samples, pollution was 13 times the safe threshold for coastal waters. Others, which were below legal limits for individual chemicals, failed tests for combined toxicity. The samples were taken from the Solent strait, which runs between the Isle of Wight and the mainland, forming part of the Channel. Sources of the Chemicals The chemicals are thought to have entered the environment from wastewater treatment plants, sewage outflows, historic landfills and nearby military sites. Researchers analysed government data, testing at water utilities, and their own samples from a dozen species of fish, seaweed and invertebrates. Impact on the Environment They found PFAS were entering the Solent in treated effluent from wastewater plants in Portsmouth and Fareham operated by Southern Water, the utility that provides drinking water and sewerage for Kent, Sussex, Hampshire and the Isle of Wight. The study also mapped 194 combined sewer overflow outfalls and more than 500 nearby historic landfills that researchers believe could also contribute to the pollution. Calls for Action Researchers said their findings highlighted the need to monitor chemicals in combination and to make a blanket ban on PFAS part of the government’s water reform agenda. Prof Alex Ford, a biologist at the University of Portsmouth and one of the study’s authors, said: “If there was an oil spill in the Solent that industry would have to pay for the restoration of those habitats, but that doesn’t happen with sewage.” Future Outlook The EU is moving towards a blanket PFAS ban, probably with some exceptions for medicine and other critical uses. The British government said it would consult on setting limits for the chemicals and carry out further tests when its own PFAS plan was published in February, promising a “framework … to understand where these chemicals are coming from, how they spread and how to reduce public and environmental exposure”.

The Failure of US Garbage Incinerators The nation's garbage incinerators are largely failing to eliminate Pfas 'forever chemicals' air pollution, and are putting people in largely low-income neighborhoods at risk, public health advocates and independent experts warn. The Industry's Misleading Claims A new industry trade group report alleges Minnesota's incinerators are reducing their forever chemical emissions by 99.6%. However, experts say the report is full of bad assumptions, incomplete data, and misleading language. The Health Risks of Pfas Pollution Pfas are a class of at least 16,000 compounds that have been linked to cancer, birth defects, decreased immunity, high cholesterol, kidney disease, and a range of other serious health problems. They are dubbed 'forever chemicals' because they do not naturally break down in the environment. The Impact on Low-Income Neighborhoods The incinerators are often located in low-income neighborhoods, putting vulnerable populations at risk. 'This trash becomes the problem of the poor and marginalized to deal with in their bodies,' said Nazir Khan, executive director of the Minnesota Environmental Justice Table. The Need for Stricter Regulations Experts say that stricter regulations are needed to address the issue of Pfas pollution. 'I'm not aware of any industrial-scale commercial incinerator that solves this problem,' said Michael Youhana, an attorney with the non-profit Earthjustice.

The Australian Government Files Record-Breaking $2 bn Lawsuit Against 3MAustralia announced on 28 May 2026 that it has launched legal action against 3M and its subsidiary 3M Australia, seeking damages exceeding $2 bn (US$1.4 bn) over PFAS contamination at defence sites.Details of the PFAS Contamination ClaimAttorney‑General Michelle Rowland said the use of per‑ and polyfluoroalkyl substances (PFAS) in aqueous film‑forming foam (AFFF) caused “major environmental and economic harm”. The claim targets 28 defence bases across the country where the foam was used for decades.More than 200,000 tonnes of contaminated soil must be removed and treated.Over 13 bn litres of water have been used in the multi‑year decontamination effort.Defence began phasing out PFAS‑containing foams in 2004.Financial Scale of the Claim and Related CostsThe government’s lawsuit is the largest ever brought by the federal government, with the following monetary figures cited:Claimed damages: $2 bn (US$1.4 bn).Costs already incurred by defence and taxpayers: > $1 bn for investigation, remediation and mitigation.In the United States, 3M agreed to a US$10.3 bn settlement in 2023 for PFAS water‑system clean‑ups.Environmental and Economic Implications for Defence SitesPFAS are “forever chemicals” that do not break down naturally, leading to long‑term soil and water contamination. Health risks identified include liver damage, lower birth weight and testicular cancer. Greens spokesperson Peter Whish‑Wilson warned that Australia risks becoming a global dumping ground for PFAS products if corporate responsibility is not enforced.Remediation requires expensive, specialised treatment facilities.The defence estate faces ongoing liability for future contamination monitoring.Previous class‑action settlements in Australia totalled $133 m for seven sites in 2023.What the Lawsuit Means for Future PFAS Regulation in AustraliaLegal experts expect the case to accelerate stricter regulation of PFAS, including tighter controls on import, use and disposal. The government’s stance signals a willingness to hold multinational corporations accountable, potentially prompting other industries to reassess PFAS usage.Potential for new federal legislation mandating full disclosure of PFAS risks.Increased scrutiny of defence procurement practices.Possible further litigation against other manufacturers of PFAS‑containing products.

The Flawed Plan to Destroy PFAS The Trump administration's plan to ditch PFAS drinking water regulations and instead attempt to destroy 'forever chemicals' on a wide scale has been met with criticism from experts. The plan, which was announced by the US Environmental Protection Agency (EPA), involves using technology to destroy PFAS, rather than implementing strong drinking water regulations. The Problem with PFAS Destruction Technology The problem with the Trump plan is that technology that fully destroys PFAS does not exist. While progress is being made in its development, it is unclear when – if ever – it may be deployed on an industrial scale. Current technologies used to destroy PFAS, from incineration to thermal oxidization, often fail to fully destroy a PFAS compound, instead essentially breaking it into smaller bits, or byproducts. The Financial Impact of PFAS Destruction The cost of removing PFAS from water can be as high as $18 million per pound. The processes of destroying PFAS are extremely expensive. Taxpayers shoulder most of the cost, and the powerful waste management industry gets paid. The Impact on Public Health Pfas are a class of at least 16,000 compounds most frequently used to make products water-, stain- and grease-resistant. They have been linked to cancer, birth defects, decreased immunity, high cholesterol, kidney disease and a range of other serious health problems. The solution is to 'turn off the tap' – reduce the production and use of PFAS – rather than attempting to destroy them after they have been released into the environment. The Future of PFAS Regulation Ultimately, PFAS destruction has all the same problems as carbon capture – it is inefficient, expensive, unreliable, prone to technical failures and clearly not an alternative to regulations. Experts argue that the focus should be on reducing the production and use of PFAS, rather than attempting to destroy them after they have been released into the environment.

The Controversy Over 'Forever Chemicals' Protests over the production of cancer-linked PFAS chemicals have spread across India, after an investigation revealed that an Italian factory shut down due to an environmental scandal was bought by an Indian company and partly rebuilt. The Relocation of the Miteni Factory At the end of last year, the Guardian revealed that the former Miteni plant in Vicenza had been acquired by the Indian company Laxmi Organic Industries. The factory produced PFAS and was shut down in 2018 after being linked to one of Italy's worst environmental contamination scandals. The Environmental Impact of PFAS The factory left behind the contamination of one of Europe's largest aquifers, affecting more than 350,000 people across the provinces of Vicenza, Verona and Padua through the drinking water. Miteni's workers were worst affected, with one former employee showing one of the highest concentrations of PFAS ever recorded in human blood. The Protests and Debate in India Since early 2025, Laxmi's site in Lote Parshuram has been fully operational, producing chemicals that will be used in pesticides, pharmaceuticals, dyes, cosmetics and other products. After publication of the Guardian's investigation, protests and political debate have spread across India. On 8 January, the first protest took place outside the gates of the Lote plant, followed live by multiple television channels. The Future of PFAS Regulations in India Several key questions remain unanswered around the relocation. Documents seen by the Guardian show that by March 2018, months before the Italian plant shut down, the plans for the Indian facility were ready and work had begun on the environmental impact assessment report and the applications for construction permits. The national debate is only expected to grow, with thousands of people taking to the streets in Lote to protest against PFAS production and call for regulations.

The Great Greenwashing: When Sustainability Meets Fast Fashion It was always about the money, wasn't it? For a while there, it seemed like the execs opining "sustainability is not a trend, it's the future" actually meant it. But when yet another global brand drops its net zero goals or stops talking about DEI, you do wonder. Recent headlines include Stella McCartney adulterating her eco gloss with a sustainable capsule collection for H&M; – don't worry, she's just "infiltrating from within" – and Lululemon being investigated for PFAS. The letdowns keep coming. The Everlane-Shein Merger: A Collision of Ideals Now the internet is reeling from a report that Shein plans to acquire Everlane, the San Francisco-based sustainable basics brand built on "radical transparency". Shein is the Chinese ultra-fast fashion giant epitomising murky supply chains and crazy-cheap landfill fashion. They release up to 10,000 styles a day, and have been making headlines of their own over secrecy and alleged links to forced Uyghur labor. Fashion reporter Lauren Sherman reported the acquisition plans this week, though neither Shein nor Everlane have confirmed. Everlane appears to be losing money fast. After layoffs in 2020 and 2023, the brand confirmed in April it was closing its San Francisco office. The Financial Calculus Behind Sustainable Fashion's Fall According to Sherman, Shein sees value in the brand's supply chain and was the only one willing to stump up the US $100m asked by Everlane's majority owner, private equity giant L Catterton (which is backed by LVMH, and owned RM Williams before Australian billionaire Andrew Forrest bought it in 2020). Shein can afford it – last year, their sales topped £2bn in the UK and $1.5bn in Australia. For my money, I bet it's not just the practical capabilities of the supply chain that interests Shein, it's the story. They could use a green glow-up. The Shifting Landscape of Ethical Fashion The Everlane tragedy follows last month's Allbirds comedy. Another publicly listed sustainable fashion company driven by Silicon Valley hype, Allbirds has given up making sneakers out of carbon neutral materials in order to flog AI. The surprise pivot came with a name change – NewBird – and a cynical cash grab. The old bird had been leaking money; the new one sent stock surging 600%. I visited Allbirds HQ the same year I interviewed Preysman. We discussed their B Corp journey, material innovation and how co-founder Joey Zwillinger reckoned "at the end of the day, people don't buy sustainable products, they buy great product experiences". I titled the podcast episode 'The Eco-Awesomeness of Allbirds – Sustainable Shoes for Changemakers'. The Future of Sustainability: Beyond Greenwashing So how do we navigate this moment? Accept it: sustainability is not hot right now. OK! This was never meant to be a popularity contest. The movement needs to get back to basics. Circularity won't save us – we must focus on workers' rights and the just transition. Have hard conversations about overproduction. Dismantle consumerism as the dominant narrative and define a properly radical approach to system change. You can't take the politics out of this, but why would you want to? As the last few months have shown us, when sustainability becomes purely about the business case, it stops meaning anything at all.

The LeadOn Friday the River Thames at Ham will host its first official swimming season as the inaugural designated bathing water in London, joining 12 other newly recognised sites across England.Thames at Ham Designated as London’s First Official Bathing WaterThe stretch of the Thames in south‑west London has been granted bathing water status after campaigners, led by Marlene Lawrence of the Teddington Bluetits, submitted evidence of year‑round swimming activity. Lawrence said, “This is amazing for the river and for the many people who enjoy it.”Nationwide Roll‑out of 13 New Bathing Water SitesEnvironmental Minister Emma Hardy announced that the new designations bring the total to 13 new monitored swimming areas across England. The sites are:Canvey Island foreshore, EssexEast Beach at West Bay, Bridport, DorsetFalcon Meadow, Bungay, SuffolkGranville Parade Beach, Sandgate, KentLittle Shore, Amble, NorthumberlandNew Brighton Beach (east), MerseysideNewton and Noss Creeks, DevonPangbourne Meadow, BerkshireQueen Elizabeth Gardens, Salisbury, WiltshireRiver Dee at Sandy Lane, Chester, CheshireRiver Fowey in Lostwithiel, CornwallRiver Swale in Richmond, YorkshireRiver Thames at Ham and Kingston, Greater LondonEnvironmental and Economic ImplicationsThe new bathing water designations expand monitoring by the Environment Agency, which will conduct weekly sampling and publish results online. Hardy highlighted the benefits: “better monitoring of our waterways, a boost for local tourism and greater confidence for local swimmers.” The move follows years of limited bathing water status, which was previously confined to coastal waters and lakes, and aims to curb sewage discharge, PFAS, and agricultural runoff.Future Outlook for River Clean‑up and MonitoringContinued oversight will involve the regulator working with communities, farmers and water companies. At Ilkley, Yorkshire Water is already investing over £85m in infrastructure to improve water quality after the Wharfe received bathing status five years ago. The Thames designation is expected to drive similar upgrades and reinforce the government’s “generational reform” of the water sector.

The Lead Levels of some of the most dangerous Pfas compounds have dramatically fallen in Canadian seabird eggs, which the authors of a new peer-reviewed study say illustrates how regulations are effective. The Event Details Researchers looked at Pfas levels in the eggs of northern gannets in the St Lawrence Seaway basin over a 55-year period. Pfas levels shot up from the 1960s through the peak of the chemicals’ use in the late 1990s and early aughts, then fell. The fall coincides with several developments – facing regulatory scrutiny, the chemical giant 3M, which is one of the largest producers of Pfas, began moving away from Pfos, among its most common and toxic compounds. By 2015, major chemical makers reached an agreement with the US Environment Protection Agency to phase out Pfos and Pfoa, the latter a similarly problematic compound. The Data Analysis Data shows the levels of Pfos fell from a peak level in the eggs of 100 parts per billion (ppb) to a level of 26ppb by 2024, a 74% drop. Levels of Pfoa are down about 40% over this time, though they ticked back up in recent years. Meanwhile, PFHxS, another common, toxic Pfas compound fell from 0.69 to 0.19ppb, or about 72%. The Impact Analysis Pfas are a class of at least 16,000 chemicals commonly used to make products resist water, stains and heat. They are called “forever chemicals” because they do not naturally break down, and they are linked to a range of health issues such as cancer, thyroid disease, kidney problems and decreased immunity. Raphael Lavoie, a co-author and ecotoxicologist with Environment and Climate Change Canada, called the findings “good news”. “We see this incredible rise to a peak where concentrations seem to be higher than toxicological threshold for those birds, then it really decreases in a nice way,” Lavoie said. “The regulations are having a good effect.” The Prediction However, it is not all good news. The chemical makers moved to a newer generation of smaller Pfas, and those also present risks to the environment and wildlife. The levels of those compounds have probably grown, and the study found one example of a shift, but the new Pfas are more difficult to measure in bird eggs because they do not accumulate in wildlife as much, Lavoie said. Moreover, compounds such as Pfos stay in the environment or animals’ bodies for decades, so the birds and environment will remain contaminated for the foreseeable future, which the authors wrote “emphasizes the importance of maintaining scientific and regulatory vigilance”.
