Cleaner Benthams Consultation submission
Cleaner Bentham today uploaded its submission on the Application to vary the Environmental Permit that PFAS user Angus Fire wants to use to "clean" it's pollutted Foam Manufactuing waste water.
The biggest issue our experts found was the lack of testing data for Waste Water said to have been taken from the Lagoons. There was also no test results from before the waste water was treated, so no way to compare the two sets of results.
The investment itself could be a bad investment for the firm, as the treatment train purchased only removes long chain PFAS from the water. So C8 and below would remain in the liquid returned to the river.
The more we dug into the actual Treatment Trains workings the more questions it left.
For example why are they not testing for the full 61 species of PFAS that the DWI require to test for PFAS before emptying it into a river that feeds into a protected drinking water river?
Why have the EA not read the DWIs study into PFAS removal and GAC technologies?
What Solvents do they use?
Formal Consultation Submission to the Environment Agency
RE: Angus Fire Ltd – Application to Vary Environmental Permit (Bentham Site)
Date: 20th
August 2025
Submitted
by: Cleaner

Reference: Angus
Fire Ltd,
Permit Variation Consultation (EPR/VP3139LS/V005)
Summary Position
This submission opposes the immediate imposition of a PFAS treatment train as a condition of Angus Fire’s permit variation. The proposal is premature, given the absence of PFAS-specific sampling data, concerns about historic non-compliance, and the technical and economic complexity of treatment train systems. There is also no data on any solvents utilised in the precedure.
1. Lack of PFAS-Specific Data
A fundamental concern is that neither Angus Fire nor the Environment Agency has published comprehensive, site-specific PFAS sampling data—including concentrations in soil, groundwater, lagoon water, rainwater runoff, Aquifer or boreholes.
Without baseline data:
- The design and scale of any remediation system remains speculative.
- There is no independent scientific basis to assess treatment effectiveness or whether it stops further environmental risk.
Angus Fire has not provided Sampling results submitted to this Permit Variation, the lab reports attached to the EA consultation are void of any PFAS results from either groundwater or from the Treatment Train. There can be know comparison made to before and after treatment.
Recommendation:
Require Angus Fire to conduct and publish a full PFAS site assessment (covering legacy and emerging PFAS) before evaluating any treatment solution.
2. Inappropriateness of Mandating a Treatment Train Without Evidence
A “treatment train” involves integrating multiple advanced technologies such as nanofiltration, electrochemical oxidation, and electro-Fenton degradation. However, as detailed in the peer-reviewed article “Treatment train approaches for the remediation of per- and polyfluoroalkyl substances (PFAS): A critical review” (DOI: 10.1016/j.jhazmat.2019.121963):
- These systems are not commercially proven on legacy PFAS-contaminated sites.
- They are energy- and cost-intensive, often requiring extreme operating conditions.
- Their success depends on detailed knowledge of site-specific PFAS profiles.
- This is only effective on PFAS that current legislation focuses on and offers no potential, with changes of legislation in the near future.
- Treamtment trains (TT) like this burn more carbons, increasing the companies carbon footprint and adding to the issues of climate change.
- Does not capture shorter carbon chains.
- This does not monitor the 61 species required to be tested for by the DWI standards. As the Lune is protected drinking water River, and the Wenning feeds into the Lune, this should be a requirement.
- Our understanding is that the only way to destroy waste (PFAS chains) captured by the TT is HTI. Currently despite evidence that has been provide to the EA, the burning temperature is too low which we know will spread the issue around the HTI site.
- Deploying such a system in the absence of PFAS data is not only inefficient—it may create a false sense of remediation progress, while deeper contamination remains unaddressed.
Recommendation:
Do not install or agree to the use of a PFAS treatment train until sufficient site data is available to determine its feasibility and effectiveness and the ability to destroy PFAS are environmentally friendly and they are able to destroy the 61 Species the DWI recommends to test for.
3. Longstanding Issues with Compliance and Transparency
Public confidence in Angus Fire’s environmental practices is low. According to publicly available reports, including those collated by Cleaner Bentham, Angus Fire has:.
- Breached its permit at least 23 times in the past decade, including unauthorized discharges and lagoon failures.
- Failed to share sampling data with local authorities or the public.
- Avoided full participation in public engagement forums
- Failed to share sampling data with local authorities or the public.
- Failed to be transparent throughout the whole process
Given this record, the focus must shift from theoretical solutions to enforcing compliance and ensuring transparency.
Recommendation:
Make any
future permit approval conditional on the publication of complete
environmental monitoring data (including PFAS), and on the
establishment of an independent local oversight mechanism.
4.
Focus on Core Remediation Priorities
A treatment train addresses runoff—not the core pollution sources, which include:
- Contaminated lagoons
- Polluted groundwater
- Legacy industrial activities (including historical foam testing)
- Destruction of PFAS contamination by HTI
Without a plan to remediate these primary sources, a treatment train applied to rainwater effluent misses the central risk to human and environmental health.
Recommendation:
Prioritise remediation of soil, groundwater, and lagoon contamination before investing in secondary or peripheral treatment technologies.
5. DWI
We
have attached a DWI (Drinking Water Inspectorate) studies show that
GAC has poor results on water treatment.
(unable to attach) so added as recomended reading.
This study was instigated by the Department for Environment and Rural Affairs.(Who are the parent department of the EA)
Final Recommendations to the Environment Agency
We respectfully request that the EA:
- Reject any proposal to impose a PFAS treatment train at this time.
- Mandate comprehensive PFAS sampling and transparent data publication.
- Delay permit approval until compliance history, pollution extent, and remediation feasibility are clearly addressed.
- Ensure independent monitoring and meaningful public engagement moving forward.
- Find alternative methods of Destruction other than HTI.
Closing Statement
In the interest of scientific integrity, public safety, and environmental justice, decision-making must be based on transparent, complete, and credible data—not unproven technical fixes.
We urge the Environment Agency to uphold its duty of care by demanding full site characterisation and accountability before allowing any further operational changes at Angus Fire’s Bentham facility.
Thank you for considering this submission.
