What's Happening?
An investigation has uncovered alarmingly high levels of per- and polyfluoroalkyl substances (Pfas) at 17 airports in England, with some levels thousands of times higher than proposed EU safe limits. These chemicals, known for their persistence in the environment and links to serious health issues, are commonly used in firefighting foams. The highest concentration was found at London Luton airport, with levels significantly exceeding EU draft limits. The presence of Pfas at airports within protected drinking water safeguard zones raises concerns about potential contamination of water sources.
Why It's Important?
The detection of high Pfas levels at airports poses significant environmental and public health risks. These chemicals are associated with various illnesses, including cancer, and their presence in water sources could lead to contamination of drinking water supplies. The findings highlight the need for stringent monitoring and regulation to prevent Pfas from entering ecosystems and watercourses. Airports are investing in investigations to identify sources and assess risks, working closely with the Environment Agency and local communities to mitigate potential impacts.
What's Next?
UK airports are spending approximately £5 million to investigate Pfas sources and assess appropriate actions. The Department for Environment, Food and Rural Affairs is considering stronger chemical regulations, including restrictions on Pfas in firefighting foams. Continued collaboration between airports, regulatory bodies, and communities is essential to address the issue and prevent contamination. The development of a restriction dossier on Pfas is underway, aiming to enhance protections and ensure environmental safety.
