In a startling revelation, a new study has found that processes designed to decontaminate hazardous liquid waste from landfills are instead dramatically increasing levels of some of the most toxic chemicals known to man. The groundbreaking research, conducted by Dr. David Megson from Manchester Metropolitan University and his colleagues, shows that treatment plants tasked with cleaning up landfill leachate are having the opposite effect, boosting concentrations of banned forever chemicals PFOA and PFOS by as much as a staggering 1,335%.
Forever Chemicals: A Growing Threat
PFAS, or per- and polyfluoroalkyl substances, are a group of approximately 15,000 synthetic chemicals prized for their nonstick properties. Ubiquitous in consumer goods and industrial applications, these compounds are notoriously long-lived, capable of persisting in the environment for thousands of years. The few PFAS that have undergone in-depth study have proven to be highly toxic, with PFOA and PFOS linked to cancers and a host of other severe health issues.
PFAS contamination has reached epidemic proportions, detectable in even the most remote corners of the Earth. Experts believe every single person in the US now carries these chemicals in their bloodstream. Landfills are a primary source of PFAS pollution, leaching the compounds into groundwater and waterways via a noxious liquid runoff known as leachate.
Treatment Plants Making Matters Worse
Conventional wisdom has held that treating landfill leachate would help mitigate the spread of PFAS. However, Dr. Megson’s team has uncovered a deeply troubling reality. Their analysis of data from 17 UK landfills reveals that, far from eliminating banned chemicals like PFOS and PFOA, treatment plants are actually creating them.
“Instead of removing the banned chemicals PFOS and PFOA, our treatment plants are actually creating them, likely being formed from the transformation of other PFAS within a chemical soup,” explains Dr. Megson.
The scope of this problem remains murky, as current monitoring practices only measure a minuscule fraction of the 15,000 PFAS variants. With potentially hundreds of landfill operators across the UK discharging treated leachate into the environment, the study’s authors warn of an urgent need for further research to develop safer disposal methods. Dr. Sara Brosché from the International Pollutants Elimination Network goes a step further, calling for a global ban on all PFAS substances.
UK Lags Behind on PFAS Regulation
While the European Commission weighs a trailblazing proposal to regulate PFAS as a single class, the UK has thus far declined to follow suit, prompting an outcry from leading PFAS experts. In an open letter, scientists urged the British government to align with the EU’s proactive stance and “follow the science,” emphasizing that categorizing PFAS as a group is essential to reining in the pollution crisis.
The stakes couldn’t be higher, stresses Dr. Sharma from the charity Chem Trust, noting the strong links between PFAS exposure and grave illnesses like kidney and testicular cancer. With climate change poised to exacerbate leaching from landfills through more frequent and severe flooding, the need for swift, decisive action grows increasingly urgent.
A Moral and Financial Imperative
Dr. Daniel Drage from the University of Birmingham sees this as a defining challenge of our time, a “multibillion pound global public health issue” that will likely outstrip government resources. He asserts that the industries that have reaped massive profits from PFAS have an ethical obligation to foot the bill and safeguard future generations from the fallout of their actions.
As the true scale of the PFAS problem comes into focus, it grows increasingly clear that half-measures and good intentions won’t cut it. Decontamination efforts that actually churn out more toxins are not a solution, but a snake eating its own tail. To have any hope of getting in front of this slow-motion catastrophe, we need a fundamental rethink of how we manage waste, regulate chemicals, and hold polluters accountable. The health of our planet and its people hangs in the balance.
