Briefing note on PFAS and drinking water

Poly-and perfluoroalkyl substances (PFAS) are a diverse group of synthetic fluorinated compounds. Due to the unique surface active properties and very high chemical and thermal stability, these substances have been widely used in many applications in industries and in products that we use in our daily life. 

The persistent nature of these substances means that they are very resistant to biodegradation and they are now ubiquitous in the environment, including- sometimes – water sources. Their widespread use in long-life domestic products, particularly carpets and furniture, means that it represents a major legacy issue to be managed.
