Common criticisms, and what the record shows

News coverage of the Hillhouse contamination brings a familiar set of responses. This page answers the common ones from published documents, so a reply can be a link rather than an argument. Every answer has its own link: use the list below, or copy the address when you land on one.

“What did you expect, moving next to a chemical factory?”

Living near a permitted industrial site is not the same as being told your garden soil may be contaminated. Wyre Council’s July 2024 letter advised washing and peeling garden produce and said residents could “continue to enjoy using your garden space as you normally would.” By March 2025 the council’s leader was advising residents to “consider not eating” garden produce, and in March 2026 the Environment Agency concluded that Occupation Road allotments met the criteria for Contaminated Land (Information and Resources). The site’s environmental permit contains no PFAS monitoring requirement on any of its air emission points (The Numbers).

Residents who grew up here did not choose where their family lived.

Nor is the contamination confined to homes beside the site. Soil testing for the Environment Agency found elevated PFAS in 187 of 199 samples in its first phase, across council-owned land up to 5 km from the facility (The Numbers). The Phase 3 report on garden soil found no clear correlation between concentration and distance, which it attributes to the spread of sampling points and the airborne nature of the deposition. Its single highest reading, 181 µg/kg, was about 700 m from the site (Phase 3 soil results).

“You should have known from your survey.”

Conveyancing searches report what is already on record, and searches cannot turn up findings that had not yet been made. The council leader’s advice to “consider not eating” garden produce dates from March 2025, and the Environment Agency’s conclusion that Occupation Road allotments met the criteria for Contaminated Land under Part 2A came in March 2026. Wyre Council’s 12 August 2026 letter said the Environment Agency’s interpretive report on the residential garden results was still awaited (Information and Resources).

There is also no legal limit to test against. England has no statutory PFAS soil limit, and the UK has no official guidance on safe levels of PFAS in blood (Bentham comparison). The investigation uses precautionary screening values applied by WSP, the Environment Agency’s contractor: 1.4 µg/kg for allotment soil and 7.6 µg/kg for residential gardens where vegetables are grown (The Numbers).

“This has been known about for years. Why the fuss now?”

The findings have arrived in stages, and each one added something new:

  • September to October 2024: Phase 1 soil testing for the Environment Agency, 187 of 199 samples elevated.
  • March 2025: the council’s leader advises residents to “consider not eating” garden produce.
  • 2 February 2026: the Food Standards Agency and Wyre Council advise against eating eggs from poultry kept “within 1km of the Hillhouse site”.
  • 5 March 2026: the Environment Agency concludes Occupation Road allotments meet the criteria for Contaminated Land.
  • 12 August 2026: Wyre Council tells residents the Environment Agency has reached the same conclusion for Sandringham Avenue allotments.
  • September 2026: blood test results for 49 residents.

The blood testing is what is new this month: results showing what is in residents themselves, rather than in their soil or food. It was arranged by a law firm, not the NHS or the council. In March 2026 the council had said blood testing would be “not appropriate” (FAQ). The dates and sources are on the timeline and the Information and Resources page.

“Everyone has PFAS in their blood anyway.”

What the testing measured is how much. Of 49 Thornton-Cleveleys residents tested by Manchester Metropolitan University, press reports say “around 70 per cent of those tested recorded levels of Perfluorooctanoic Acid, known as PFOA, which could place them at increased risk of adverse health effects under guidelines used in Germany and the United States”. Environment Journal reported that “69.4% had PFOA concentrations above 20 nanograms per millilitre (ng/ml)” and that none of those tested were below 2 ng/ml, the lower US guidance threshold, and that a replacement chemical, EEA-NH4, was detected in the blood of 10 residents. The figures describe the 49 people tested, not the whole area, and the reports’ description of them as PFOA may refer to a combined total of several PFAS (blood test results).

For comparison, testing of 39 people near a PFAS source in Bentham, North Yorkshire, found 9 above the 20 ng/ml threshold in US guidance from the National Academies of Sciences, Engineering, and Medicine (Bentham comparison).

“Blood tests can’t show what your future health risk is.”

Lancashire’s Director of Public Health said residents had been offered blood tests that “cannot show where the exposure occurred, whether PFAS has caused a health condition or what their future health risk may be” (BBC, 24 September 2026).

A blood test cannot predict whether one particular person will become ill, and this site does not claim otherwise. That limitation does not stop blood levels being used to place people in risk bands. The US guidance used to interpret these results places levels above 20 ng/ml in a band of increased risk, with additional screening advised (blood test results). Leigh Day’s fact sheet describes the benchmarks as “US guidelines which help experts to interpret PFAS results and the risks, if any, that may be associated with certain levels.”

The council’s own position has not been consistent. On 3 March 2026 the Leader of Wyre Council publicly called for blood tests; on 6 March the council said in an FOI response that PFAS blood testing would be “not appropriate” and that results would be “uninterpretable” (FAQ).

“It’s scaremongering. Nobody has proved it made anyone ill.”

This site does not claim that any individual’s illness was caused by PFAS. That is a question for medical and legal experts. What it reports are findings on the record:

  • Lancashire County Council’s own health assessment found 14 kidney cancer cases where about 6 were expected in the neighbourhood nearest the site between 2003 and 2022, a statistically significant excess, and then concluded that no further cluster investigation is needed (the council’s kidney cancer assessment).
  • The Environment Agency concluded that Occupation Road allotments meet the statutory criteria for Contaminated Land, based on PFOA in soil and produce, with “a significant possibility it could cause significant harm to health” (Information and Resources).
  • The Food Standards Agency and Wyre Council advised against eating eggs from poultry kept “within 1km of the Hillhouse site” (FAQ).
  • The International Agency for Research on Cancer classifies PFOA as a Group 1 carcinogen (Evidence).

“Most gardens came back fine.”

That describes shallow samples. Wyre Council’s August 2026 letter said most shallow garden results were below the precautionary screening level for PFOA (Information and Resources). The fuller survey tells a different story.

At the one garden whose full Phase 3 results have been published, 24 of 25 samples exceeded the residential garden screening value and all 25 exceeded the allotment value. The highest reading, 119 µg/kg, was at the deepest point sampled, 0.60 m, and contamination “was still rising when sampling stopped.” At multiple sample points PFOA increased with depth, as it did in Phases 1 and 2, and “the true depth of contamination remains unknown” (The Numbers). One garden does not establish conditions in others; that is why the full results matter. The highest reading in the Phase 3 garden survey, 181 µg/kg, was about 700 m from the site (Phase 3 soil results). Elevated PFAS was detected in every egg sample from the four poultry keepers tested (Information and Resources).

“If it was that bad, the council would have told us.”

The messages residents have received have not been consistent. In July 2024 Wyre Council’s letter said residents could “continue to enjoy using your garden space as you normally would.” In March 2025 the council’s leader advised residents to “consider not eating” garden produce. In August 2026, with two allotments found to meet the criteria for contaminated land, the UK Health Security Agency’s advice was unchanged: gardens can be used as normal, with hands washed and produce washed and peeled (Information and Resources).

On 3 March 2026 the council’s leader publicly called for blood tests; on 6 March the council said testing would be “not appropriate” and results “uninterpretable” (FAQ). Lancashire County Council’s kidney cancer assessment found a statistically significant excess next to the site and concluded that no further cluster investigation is needed (kidney cancer assessment). And Wyre Council’s 12 August 2026 letter said the Environment Agency’s interpretive report on residential gardens was still awaited (Information and Resources).

“The plant is closing, so the problem is solved.”

AGC has announced that production at Hillhouse is “expected to cease by 31 December 2026” (AGC Chemicals Europe, 14 September 2026). Ending production does not remove the contamination already in the ground: PFOA “persists in the environment for an estimated 1,000+ years” (timeline), and this site has set out evidence of “re-emission from existing on-site PFAS reservoirs” (The Numbers).

“Just don’t eat your own vegetables or eggs, then.”

Food is one route, not the only one. PFOA has been detected in air samples at Hazelrigg, about 20 km from the site (timeline), and independent research has detected EEA-NH4 there too (the 1 km zone). Reports of the blood results say those living within one kilometre of the site had the highest average levels (blood test results). Being advised not to eat food from your own garden is part of what residents are dealing with, not a solution to it.

“It’s not in the tap water, so what’s the problem?”

This site does not claim that it is. Mains water is supplied and treated by United Utilities, and the high water readings published on this site come from industrial discharge, not treated drinking water (FAQ). The findings that matter here are in garden and allotment soil, produce, eggs and air.

“PFAS is in frying pans and raincoats. You can’t blame one factory.”

The UK Health Security Agency says exposure to PFAS is “widespread”, from sources including food, drinking water, air and everyday products (BBC, 24 September 2026). Widespread exposure does not explain away the measured local findings: PFOA in the soil of local allotments and gardens, and in eggs from local hens. The Phase 3 soil results show contamination that is directional rather than evenly spread, with the highest readings to the south-east of the site (Phase 3 soil results).

“The amounts are tiny, just micrograms.”

The screening values are set in the same units: 1.4 µg/kg for allotment soil and 7.6 µg/kg for gardens where vegetables are grown. At the one garden whose full Phase 3 results have been published, 24 of 25 samples exceeded the garden value, all 25 exceeded the allotment value, and the highest was about 16 times the garden value (The Numbers).

“Why blame today’s company for what ICI did decades ago?”

Residents are not the ones who decide responsibility. If a formal contaminated-land determination is made, Wyre Council has stated it will “identify those responsible and secure remediation” (Information and Resources); any legal process is separate. The history of who operated the site, and what is and is not known about attribution, is set out in the FAQ.

“Why don’t you just move?”

Moving means selling a home with a known contamination issue, and property sellers have disclosure obligations regarding known material issues (FAQ). It would not change what has already been found in residents’ blood.

“Publicising this is what’s hurting house prices.”

The contamination is in the soil and eggs whether anyone talks about it or not. Contamination does not begin when it is reported, and staying quiet would not lower a single reading. Property sellers also have disclosure obligations regarding known material issues (FAQ).

“This will cost people their jobs.”

The closure is AGC’s decision. On 14 September 2026 it announced “the decision to cease manufacturing at its Hillhouse site in Thornton Cleveleys,” with production “expected to cease by 31 December 2026.” The reason it gave: “AGCCE has concluded that there is no viable solution to keep the site operating in the context of a volatile and competitive market” (AGC Chemicals Europe, 14 September 2026). Its July 2026 announcement of the proposal had given “a loss for the past four years” as a reason; Hillhouse Watch has compared that statement with the company’s filed accounts.

“They’re only in it for compensation.”

Leigh Day, the law firm investigating possible legal action, says it is still assessing whether action is viable. Its September 2026 fact sheet says that if a claim goes ahead it “would be seeking monies to facilitate medical monitoring and PFAS reduction medications”. The Government’s own PFAS Plan, published in February 2026, includes statements on the principle that polluters should pay (Defra PFAS Plan). For how to contact Leigh Day, see Contacting Leigh Day.

Updated 25 September 2026: nine answers added; the jobs answer updated to AGC’s 14 September confirmation (it previously cited only the July proposal); the “factory”, “survey”, “why now”, “scaremongering”, “most gardens” and “house prices” answers now set out more of the published record.

Clarified 24 September 2026: the “most gardens” answer originally said, in this site’s own words, that about 70 per cent of residents tested had high PFOA. The published reports call the figure PFOA, but the thresholds they cite apply to a combined total of several PFAS, so the answer now attributes the figure to the reports and links to the fuller explanation.
