PFAS Forever Chemicals: Why Industry Must Be Held Accountable

A letter published in response to recent reporting on per- and polyfluoroalkyl substances — the synthetic compounds collectively known as PFAS, or “forever chemicals” — cuts through the noise of individual health advice with a precision that deserves serious attention. Its author, a mother of two based in Exeter, describes reading a piece on the link between prenatal and early-life PFAS exposure and elevated intestinal inflammation in children — inflammation that researchers associate with increased colorectal cancer risk — and arriving at the article’s proposed solutions with a mixture of despair and fury. The solutions offered were these: use water filtration systems capable of removing PFAS, buy organic food, avoid waterproof clothing, avoid stain-repellent treatments. The letter’s central argument is blunt and difficult to refute: the systematic contamination of food, water, and consumer goods by industrial chemicals is not a problem that mothers, or parents more broadly, are equipped to solve by shopping differently.

The frustration the letter captures is not merely personal; it reflects a structural accountability failure that has played out across decades of chemical regulation. PFAS compounds — numbering in the thousands, resistant to environmental degradation, and detectable in the blood of populations across every continent — entered widespread commercial use long before their health consequences were understood, and have remained embedded in supply chains long after those consequences became scientifically documented. They appear in non-stick cookware, food packaging, waterproof textiles, firefighting foam, and, critically, in the water systems that serve communities with no meaningful choice about their source of drinking water. The suggestion that individual consumers can opt their way out of this exposure landscape is, at best, a failure of imagination; at worst, it functions as a mechanism for displacing corporate and governmental liability onto the people least positioned to bear it.

The letter’s author frames this displacement with deliberate clarity. It is the responsibility of governments to legislate. It is the responsibility of large agricultural producers not to saturate food systems with chemical inputs. It is the responsibility of water utilities to deliver water that does not require households to purchase additional filtration technology simply to render it safe. These are not radical propositions; they are restatements of the foundational premise of public health regulation, a premise that has been progressively eroded by the lobbying power of chemical manufacturers, the slow pace of regulatory agencies, and a political culture that consistently treats industrial accountability as an economic burden while treating individual precaution as a neutral, costless alternative. It is neither neutral nor costless. Organic food commands a significant price premium that excludes the majority of working families. Whole-house or under-sink filtration systems capable of removing PFAS are not standard fittings in social housing. Waterproof clothing is not a luxury for parents navigating school runs in wet climates — it is functional necessity.

What the letter also surfaces, without stating it in these terms, is the gendered dimension of this burden. The advice to avoid PFAS exposure is disproportionately directed at mothers — during pregnancy, during breastfeeding, during the years of intensive early childhood care when women remain statistically more likely to be the primary managers of household consumption decisions. The mental load of navigating contradictory health guidance, of weighing glass versus plastic, organic versus plastic-free, is not evenly distributed, and the consequences of getting it wrong — according to the dominant framing — fall on the child, and therefore on the mother’s conscience. This is a form of moral coercion that the evidence does not justify, because the evidence points not to inadequate maternal vigilance but to inadequate industrial and regulatory governance.

The science linking PFAS to adverse health outcomes has hardened considerably in recent years. Regulatory responses have been uneven and, in many jurisdictions, conspicuously slow relative to the pace of accumulating evidence. The European Union has moved toward broader PFAS restrictions under its Chemicals Strategy for Sustainability, though implementation timelines remain contested and industry challenges have introduced delays. In the United States, the Environmental Protection Agency established enforceable maximum contaminant levels for certain PFAS in drinking water in 2024 — a significant step, but one that arrived decades after the compounds’ proliferation and that leaves substantial gaps in coverage. In the United Kingdom, regulatory frameworks lag further still, and water companies facing PFAS contamination issues have faced limited statutory compulsion to remediate. Against this backdrop, the advice to buy a water filter is not a supplement to systemic action; it is, in practice, a substitute for it.

The letter from Exeter is short. It does not cite regulatory frameworks or toxicological studies. It does not need to. It articulates, with the clarity that comes from lived experience rather than analytical distance, what a functioning accountability system would look like — and what it currently does not. The cost and burden of avoiding industrial contamination should not be privatised onto the shoulders of parents who did not manufacture the chemicals, did not lobby against their regulation, and cannot, by any realistic measure, spend or filter their way to safety in a contaminated environment. That is a task for states and corporations, and the continued failure to treat it as such is not an oversight. It is a choice.
