PFAS chemicals, often called 'forever chemicals,' are a group of man-made substances found in many everyday products. Recently, UK water supplies have been flagged for contamination with these chemicals, raising concerns about health risks and environmental impact. Curious about what PFAS are, how they affect us, and what’s being done about it? Keep reading to find out more.

What are PFAS chemicals?
PFAS (per- and polyfluoroalkyl substances) are a large group of human-made chemicals used in products like non-stick cookware, water-repellent clothing, firefighting foam, and industrial processes. They are called 'forever chemicals' because they do not break down easily in the environment or in the human body.
-
Why are PFAS chemicals dangerous?
PFAS chemicals are linked to serious health issues, including cancer, hormone disruption, immune system problems, and developmental effects. Their persistence means they can accumulate over time, increasing the risk of adverse health outcomes.
-
Which UK water companies are affected by PFAS contamination?
Several UK water companies, including Anglian Water and Wessex Water, have been issued enforcement notices for exceeding safety limits of PFAS in their water sources. Over 9,400 tests have detected dangerous levels, highlighting the widespread nature of the issue.
-
What steps are being taken to address water contamination?
UK regulators are actively working with water companies to reduce PFAS levels. Enforcement notices have been issued, and efforts include improving filtration, monitoring, and stricter regulations. However, critics argue that current limits are not strict enough, and stronger measures are needed.
-
How does PFAS exposure impact health?
Exposure to PFAS can lead to increased risks of cancer, hormonal imbalances, immune system suppression, and developmental issues in children. Since these chemicals can accumulate in the body over time, reducing exposure is crucial for health safety.
-
Are there regulations in place for PFAS in the UK?
Currently, the UK’s limits for PFAS are less strict than those in the US. Critics, including the Royal Society of Chemistry, are calling for legally binding standards to better protect public health and ensure water safety.
