A landmark lawsuit filed by Australia against American conglomerate 3M over its production of toxic PFAS chemicals is exposing a dangerous gap in Britain’s own regulatory armour. The case, which accuses the Minnesota-based firm of knowingly contaminating water supplies for decades, has reignited fears that UK households are being left defenceless against the same substances. As Australia’s government seeks compensation for widespread environmental damage and health costs, British campaigners argue that London’s failure to hold 3M accountable leaves the country’s sovereignty and citizens’ safety in jeopardy.
The so-called “forever chemicals” perfluoroalkyl and polyfluoroalkyl substances (PFAS) are used in everything from non-stick pans to firefighting foam. They do not break down in the environment, accumulating in soil, water and the human body. Studies have linked PFAS exposure to cancers, liver damage and reduced immune response. Australia’s legal action claims that 3M, which manufactured the largest share of PFAS globally, suppressed evidence of the chemicals’ dangers for profits. The suit demands billions in cleanup costs and medical monitoring for affected communities.
Here in Britain, the response has been muted. The Environment Agency has set advisory levels for PFAS in drinking water, but campaigners say they are too weak to protect public health. Unlike Australia, the UK has not launched a class-action suit or sought damages from 3M. Instead, the costs of monitoring and treatment fall to local water companies and council tax payers. “This is a sovereignty issue,” said Dr. Emily Shaw, a water contamination expert at the University of Sheffield. “If our government will not pursue the polluters, then we are effectively letting a foreign corporation dictate the safety of our water. We need a legal framework that puts British citizens first.”
The disparity is stark. In the United States, nearly 4,000 lawsuits against 3M and other PFAS manufacturers have been consolidated into a multi-district litigation. Chemical giant DuPont settled a similar case for $671 million. Australia’s suit, filed in the Federal Court, could set a precedent for other nations. But the UK, a close ally of both the US and Australia, has remained on the sidelines. The Department for Environment, Food and Rural Affairs (Defra) insists that current regulations are “among the strictest in the world” and points to a 2021 ban on PFAS in firefighting foams. Yet critics note that the ban only applies to new uses, not existing contamination, and that PFAS are still used in many consumer products.
The human cost is already being felt. In the Thames Valley, residents of a housing estate built on a former military base discovered PFAS levels in their well water 20 times the safe limit. One mother, Sarah Goode, told this paper that her three-year-old daughter has developed unexplained skin rashes and digestive issues. “We are being slowly poisoned and no one seems to care,” she said. “Why should a company based thousands of miles away decide whether my child gets cancer?” The water company, Thames Water, says it is “working with regulators” but has no immediate plan to filter the chemicals.
Unions are also raising the alarm. Firefighters, who use PFAS-based foams in training exercises, have some of the highest PFAS blood levels in the country. The Fire Brigades Union has called for a ban on all PFAS foams and for health monitoring of its members. “Our members are human canaries in this toxic coal mine,” said union general secretary Matt Wrack. “The government must act now, not wait for a lawsuit from Australia to shame them into it.”
The 3M case goes beyond environmental health. It strikes at the heart of Britain’s post-Brexit trade negotiations. The UK is currently pursuing a free trade agreement with Australia, and some fear that a lawsuit against a major US corporation could complicate relations with both countries. But many argue that sovereignty means putting the well-being of British people above corporate interests. “If we can’t protect our own citizens from a foreign company that has knowingly poisoned us, what does sovereignty even mean?” asked Labour MP for Sheffield Central, Paul Blomfield, who is tabling a private members’ bill on PFAS regulation.
As the Australian lawsuit gathers momentum, the pressure on Westminster grows. The Treasury must decide whether to join the fight for compensation or continue to let a foreign company write the rules. For families in impacted communities, the answer is clear: the price of safety should not be paid at the kitchen table.
