Residents in High Bentham have a four‑week window to shape how legacy PFAS is managed on their doorstep. From Thursday 5 March until Wednesday 1 April 2026, the Environment Agency (EA) is consulting on a ‘minded to’ decision to vary Angus Fire’s environmental permit (reference EPR/XP3832NV/V004) to install an effluent treatment plant, with treated water released to the River Wenning. The EA has not made a final decision and is inviting comments before it does. (gov.uk)

Under the draft decision, the plant would treat rainwater that falls on historically contaminated areas of the site, reducing PFAS in stored and future runoff before controlled discharge to the Wenning. The Agency says proposed residual PFAS in the treated flow would align with levels currently accepted as best practice for PFAS treatment processes, and a draft permit sets conditions the operator must meet if granted.

Angus Fire no longer manufactures firefighting foam at High Bentham, and testing of PFAS‑containing foams at the site ceased in 2022 according to North Yorkshire Council. The council also reports very high PFAS detected in a borehole beneath the site-now capped and never used for drinking water-underscoring why a robust treatment and monitoring regime matters.

Context is critical. The EA’s own evidence shows PFOS-a long‑studied PFAS-has been found in all fish sampled from fresh, estuarine and coastal waters around England, and since 2021 the Agency has analysed over 11,000 water samples for PFAS from 3,000 locations. That ubiquity means any discharge, even when treated, must be tightly controlled and transparently reported. (consult.environment-agency.gov.uk)

Health authorities continue to tighten the science. EFSA’s 2020 opinion set a tolerable weekly intake of 4.4 ng/kg body weight for the sum of four PFAS (PFOS, PFOA, PFNA and PFHxS), while the UK Drinking Water Inspectorate notes IARC’s classification of PFOA as carcinogenic to humans (Group 1) and PFOS as possibly carcinogenic (Group 2B). These food and drinking‑water benchmarks are not the same as river discharge limits, but they explain why communities seek the lowest feasible concentrations. (efsa.europa.eu)

What works technically is well established. International guidance identifies granular activated carbon, PFAS‑selective ion exchange resins and high‑pressure membranes such as reverse osmosis or nanofiltration as effective options to strip PFAS from water. Any permit should also spell out how spent media and membrane concentrates will be handled so pollution isn’t simply shifted from water to waste. (epa.gov)

Standards are evolving too. Only PFOS currently has a statutory environmental quality standard in UK surface waters, but Defra and the EA are developing thresholds for managing other PFAS in the water environment. In parallel, the Drinking Water Inspectorate has moved utilities to a three‑tier risk approach and now expects reporting for the ‘sum of PFAS’ across 48 named substances-useful as a monitoring template even though this consultation is about river discharge, not tap water. (gov.uk)

For the Wenning and the wider Lune catchment, strong permit conditions would build confidence: frequent upstream‑and‑downstream PFAS sampling covering priority analytes; clear trigger levels for operational changes; independent audits; and public monthly reporting. Adding periodic fish‑tissue sampling would track bioaccumulation risks highlighted by the EA’s national findings. These are practical measures communities can request through consultation responses.

Geography matters here. The River Wenning runs through High and Low Bentham before joining the River Lune near Hornby, connecting rural communities and wildlife habitats downstream. Catchment‑wide thinking-especially during heavy rainfall when runoff spikes-will be essential to ensure the treatment plant delivers real‑world protection. (en.wikipedia.org)

Residents, anglers, businesses and local health advocates can now read the draft permit and decision on the EA’s Citizen Space and respond online or by email to pscpublicresponse@environment‑agency.gov.uk. The consultation window is fixed: Thursday 5 March to Wednesday 1 April 2026. Clear, evidence‑backed comments on monitoring frequency, public reporting and waste handling will carry weight. (gov.uk)

If you use a private borehole or spring locally, ask your council’s Environmental Health team about PFAS testing and mitigation. The Drinking Water Inspectorate advises a precautionary approach, with actions to progressively reduce concentrations-especially where any PFAS are detected at or above 0.1 µg/L in private supplies. North Yorkshire Council can advise on local arrangements. (dwi.gov.uk)

What happens next is straightforward. The EA will review consultation responses alongside the evidence base and decide whether to issue the variation and on what terms. Clear, enforceable limits and transparent monitoring can turn a legacy pollution problem into a managed, steadily improving situation for the Wenning and the Lune. (gov.uk)
