Investigation Update: March 2026 — Governance Questions, a Hidden Corporate Layer, and the Unwarned Estuary

The multi-agency drop-in on 12 March 2026 was the first opportunity for residents to put direct questions to the Environment Agency (EA), Wyre Council, and UK Health Security Agency (UKHSA) since the investigation into PFAS contamination at the Hillhouse industrial estate became public. Subsequent document research has identified further questions about the regulatory structure — specifically about corporate permit arrangements and the absence of any public warning at discharge points into the River Wyre.

The Drop-In: 12 March 2026

The meeting was held at Thornton-Cleveleys FC. AGC Chemicals were not present. Approximately three agencies were represented (Wyre Council, UKHSA, EA), along with Lancashire County Council.

Who is the lead agency?

One of the clearest findings from the drop-in was the absence of agreement on a basic governance question. When asked independently, each of the three agencies gave a different answer about who leads the multi-agency investigation:

Wyre Council said the EA was the lead.
UKHSA said they believed it was the EA but were not certain.
EA said there was not really a single lead — they were conducting the scientific investigation, but legal responsibility for contaminated land under Part IIA of the Environmental Protection Act 1990 rests with Wyre Council.

This circular answer is itself informative. The health protection agency does not know the governance structure of an investigation into a contamination event affecting a populated area. Neither the 12 March meeting nor any public document to date has provided a written answer to this question.

This is compounded by the EA’s own public statement, quoted in the BBC News article from the same day, describing the investigation as having been “launched by Wyre Council” — which directly contradicts Wyre’s claim that the EA leads it.

We have written to each agency requesting written confirmation of who they consider to be the lead. Three different written answers would be as significant as three different verbal ones.

Wyre Council and the Council Leader’s statements

In early March, Wyre Council Leader Michael Vincent gave a public interview to BBC News describing himself as “disappointed” at the pace of AGC’s own investigation and publicly calling for PFAS blood testing for residents. However, when his own council’s position on blood testing was raised at the drop-in, a Wyre Council officer stated that Councillor Vincent’s comments were not representative of what Wyre’s official stance was — as he was a politician rather than a technical officer.

This creates an internal contradiction: the Council’s elected leader making public statements about the health response, while the same council’s officers distance themselves from those statements in conversation with residents. The Council’s official position — as stated in its EIR FOI response of 6 March 2026 — explicitly discourages biomonitoring.

Blood testing: identical messaging from two agencies

Both Wyre Council’s FOI response and the UKHSA representative at the drop-in gave near-identical positions on blood testing: that results would not be interpretable, that PFAS is found in everyone’s blood at background levels, and that testing would cause additional distress. At the drop-in, the UKHSA representative actively discouraged private testing and was unreceptive to discussion of population-level biomonitoring for the affected community.

When the Jersey PFAS biomonitoring programme was raised as a precedent — a programme in which UKHSA’s own agency, the UK Health Security Agency, is actively involved — the representative indicated they would not have advised it and appeared to view it as outside their remit.

This position appears to be a policy decision rather than a scientific one. The science does not support the claim that PFAS blood levels are uninterpretable: German Human Biomonitoring Commission reference ranges exist, EFSA has published tolerable weekly intake figures, and Jersey is currently running an active interpretation programme. “We cannot interpret results” and “Jersey is interpreting results” cannot both be true.

EA officer: data not in the public domain

The most substantive conversation at the drop-in was with the EA officer. He stated explicitly that there are things known about the investigation that are not yet in the public domain. He described Phase 3 results as still being analysed, with Phase 4 scope not yet determined — dependent on Phase 3 outcomes. The investigation remains non-aggregating: it does not, for example, combine air deposition data with water data or groundwater data to form a total exposure picture.

The officer came across as constrained rather than evasive — as if the information asymmetry between what the agencies know and what residents have been told was a source of some personal discomfort. That is, of course, a subjective impression. The objective fact is that data exists which has not yet been shared with the public.

Investigation scope: one stack, one chemical, one pathway

Wyre Council confirmed at the drop-in that the current investigation is scoped to historic atmospheric deposition of PFOA from a single emission point — not from all 15 air emission points listed in AGC’s environmental permit. The pathway considered is air → soil → home-grown produce.

There is a methodological problem with this framing that was not answered at the drop-in: soil PFOA contamination near the site cannot be attributed exclusively to atmospheric deposition. The site also discharges to the River Wyre, which has a floodplain. Multiple contamination pathways converge in the same area. The investigation’s foundational assumption — that the soil contamination arrived from one stack, via one pathway — is not testable from the soil data alone.

GP inconsistency

Following a separate enquiry at a local GP practice, the position on private blood testing was found to contradict the council’s official stance. The practice’s reception staff indicated that the NHS would not fund PFAS testing, but that the practice sees no clinical reason not to test and advises patients to arrange private testing and submit the invoice to Wyre Council. The council’s own EIR FOI response, dated 6 March 2026, explicitly states that it would not recommend biomonitoring “through either NHS services or private blood tests.”

The clinical professionals whose patients live in the affected area hold a different view from the council’s public health advice. This is a verbal position only at present; we are seeking written confirmation from the practice.

Regulatory Gaps: New Findings, March 2026

HSE: not at the table

The multi-agency investigation involves the EA (environmental regulation), Wyre Council (contaminated land), UKHSA (health), and Lancashire County Council. One agency that does not appear in any published description of the investigation is the Health and Safety Executive (HSE).

Section 3(1) of the Health and Safety at Work etc. Act 1974 places a duty on employers to conduct their undertaking in such a way as to ensure, so far as is reasonably practicable, that persons not in their employment — including the public — are not exposed to risks to their health or safety. This duty is enforced by the HSE.

The contamination at Hillhouse is, in part, the result of how the site has been operated over decades. Whether there is any HSE role in the current investigation, and whether HSE has previously been involved with the site, are questions that have not been addressed in any published material. We have submitted a formal concern report to HSE and requested confirmation of their prior involvement, if any, with AGC’s operations at Hillhouse.

The Wyre estuary: active discharge, no warning

Independent monitoring data published in peer-reviewed literature (Cousins, Dalmijn et al., Environmental Science & Technology, 2025; PMC12312159) measured PFOA at up to 20,624 ng/L in water near the Hillhouse site in 2023. The proposed UK Environmental Quality Standard (EQS) for PFOA in surface water is 100 ng/L. This puts the measured concentration at over 200 times the proposed standard at that sampling location.

The same study measured EEA-NH4 (the PFAS compound currently used on site) at up to 1,744 ng/L — the first reported quantification of EEA-NH4 in any environmental matrix.

The EA’s own risk evaluation (2023) estimates that approximately 800 kg/year of EEA-NH4 currently discharges to the River Wyre from the Hillhouse site. This discharge is ongoing and active.

The River Wyre estuary is publicly accessible. Dog walkers, families, anglers, and children are present. There are no warning signs at or near the discharge points. No public health advisory has been issued for the estuary. No guidance exists for members of the public who walk along or interact with the water near the outfalls.

By contrast, the allotments within the 1km zone were closed on a precautionary basis following Phase 1 soil sampling results — a precautionary action taken before the contamination data was fully characterised. The waterway receiving active, measured, ongoing discharge has received no equivalent precautionary response.

This asymmetry — precautionary closure of allotments, no precautionary signage on the receiving waterway — does not appear to have a publicly stated justification.

Corporate Structure: The Permit Holder You Haven’t Heard Of

Document research conducted in March 2026 has identified a regulatory structure that is not apparent from the publicly described investigation.

AGC Chemicals Europe holds an Integrated Pollution Prevention and Control / IED permit (EPR/BU5453IY) for the Hillhouse site. This permit covers what goes into the on-site drainage and effluent treatment system.

The discharge consents for the actual outfalls from the site — the pipes that carry treated and surface water into the River Wyre and Royles Brook — are held by a separate company: Thornton Facilities Management Limited (Companies House number 04673430). Thornton FM is registered at One St Peter’s Square, Manchester, and its operating address is Hillhouse International, Fleetwood Road North. It is a site management company, not a chemical manufacturer. It is owned by NPL Landcare Holdings Limited, the site managers.

Thornton FM holds two EA discharge consents:

Permit 017290033 — discharge to the Wyre Estuary, classed as trade/contaminated surface water. This permit was issued in 2008 and is at version 14.

Permit 017290384 — discharge to Royles Brook (which flows into the River Wyre), classed as sewage and trade combined surface water. This permit was first issued on 21 January 1999. It is at version 1. It has not been updated in 27 years.

Neither permit contains PFAS monitoring requirements. Neither permit has been updated to reflect the PFAS contamination now documented in the waterway.

The result is a split regulatory picture. AGC holds the permit for what goes into the effluent system; Thornton FM holds the permits for what comes out the other end. Neither permit requires monitoring for the chemicals measured in the waterway by independent researchers. The pipe that discharges into the Wyre Estuary is formally owned, for permit purposes, by a property management company incorporated in 2003 as a shelf company (originally Inhoco 2814 Limited).

This dual-permit structure does not in itself establish fault or intent. But it does mean that the EA’s permitting framework — as currently configured — contains no mechanism to require PFAS monitoring at the actual point of discharge into the estuary. That is a factual gap in the regulatory framework, whatever its explanation.

We have submitted a formal request to the EA asking how these permits interact, whether the split structure was designed or incidental, and whether the EA considers the current permit conditions adequate given the documented contamination.

Leigh Day

Leigh Day solicitors are publicly investigating potential legal claims arising from the Hillhouse contamination. They attended the 12 March drop-in.

Following the drop-in, Leigh Day has indicated that some of the technical information provided to residents at the meeting was not well-founded. They are currently pursuing blood testing for at least one family living adjacent to the affected allotments — a step that the responsible public health agencies have declined to take.

The Jersey Independent PFAS Scientific Advisory Panel published its Third Report earlier this year. Leigh Day has shared this report, which recommends biomonitoring for communities impacted by PFAS exposure. Jersey’s programme is cited by Leigh Day as a relevant precedent for what a proportionate health response looks like; the same precedent that UKHSA appeared to decline to endorse at the 12 March drop-in.

Leigh Day’s public contact address for PFAS enquiries is [email protected].

Summary of Questions Raised

The events of the past week raise several questions that have not been answered in public:

Which agency is the lead in the multi-agency investigation — and can each agency confirm this in writing?
Why has the investigation scope been limited to one emission point, one chemical, and one pathway, given that the site has 15 air emission points and discharges directly to the Wyre?
Why has no public warning been placed at the discharge points into the River Wyre estuary, given the measured concentrations of PFOA and EEA-NH4 in the water?
Why does the discharge consent for the Hillhouse outfalls sit with a property management company (Thornton FM), and how have those permits not been updated to include PFAS monitoring?
Why is the Royles Brook discharge consent (permit 017290384) still at version 1, unchanged since January 1999?
Has HSE been consulted as part of the multi-agency investigation, and if not, why not?

We have submitted or are preparing formal requests to the EA, Wyre Council, and HSE on each of these questions. Responses will be published here when received.
