01
Core Findings at the Former Airbase
A recent investigation commissioned by developer Dorchester Living revealed “unacceptable” concentrations of poly-fluoroalkyl substances (PFAS) across the former RAF Upper Heyford site, which is slated for a new housing estate of approximately 9,000 homes. The testing, uploaded to the Cherwell District Council’s planning portal, identified PFAS levels that exceed environmental standards in both soil and water samples.
02
Background and Context
PFAS, often called “forever chemicals,” are a large class of synthetic compounds that persist in the environment and have been linked to cancer and other health risks. Military installations and airports have long been recognised as PFAS hotspots because firefighting foams containing these chemicals were used extensively for training.
03
Data and Statistics
- The developer’s report indicates PFAS concentrations higher than those recorded in Bentham, Yorkshire, which the EA previously identified as the UK location with the highest PFAS levels.
- Independent testing by Gallos Brook Environmental Group detected elevated PFAS in more than a dozen streams flowing from beneath the former base.
- A separate water-quality study found PFAS present in every ground- and surface-water sample, all of which surpassed the EA’s environmental thresholds.

Official Statements and Responses
Paul Silver, chief executive of Dorchester Living, emphasized that separate soil samples taken from areas designated for residential use were deemed “safe for use.” The Environment Agency reiterated that military sites remain primary PFAS sources and highlighted the need for thorough remediation before any housing construction proceeds. Gallos Brook Environmental Group’s findings were presented as evidence of widespread contamination affecting local waterways.
05
Implications for the Planned Development
The discovery of PFAS at levels surpassing national standards raises significant concerns for the proposed 9,000-home project. Remediation requirements could delay construction, increase costs, and necessitate additional monitoring to protect public health and local ecosystems. The situation also underscores broader challenges in repurposing former defence sites where historic firefighting practices have left lasting chemical legacies.
