## Key points

- Report says PFAS contamination at Upper Heyford is the UK’s worst identified.
- Tests found widespread contamination in water at the former base.
- Developer says more investigation and possible remediation are planned.

## Summary

A report found PFAS contamination at the former RAF Upper Heyford base at levels described as the worst identified in the UK. The finding matters because the site is earmarked for 9,000 homes, while residents and campaigners have raised concerns about pollution reaching nearby waterways and the safety of existing developments.

The report identified the former firefighting practice pond as the most significant ongoing source, and another investigation found widespread contamination in ground and surface water, with all samples exceeding environmental standards. Independent testing found elevated PFAS in more than a dozen streams; results from a primary school site also exceeded safe levels under environmental quality standards. Developer Dorchester Living says residential soil samples showed the area was safe for use and proposes further phased investigation and remediation, but those additional results have not been published.
