PFAS

Per-and polyfluoroalkyl substances (PFAS) are known as forever chemicals because of their persistence in the environment. These chemicals are used to make every day products like cosmetics, cookware and clothing. They're also used to create firefighting foam.

We test for PFAS compounds as part of our routine sampling schedule for both untreated and treated water. We also risk assess all our raw water sites to make sure our drinking water meets the high standards set by our regulator, the Drinking Water Inspectorate (DWI).

Based upon the most up to date guidance from DWI, the low levels of PFAS detected in some untreated water in the UK has no acute or immediate impact on human health.

We would consider options to mitigate PFAS compounds if this ever becomes necessary, however our sample results to date agree with the outputs from our catchment investigations and our water supplies are considered to be low risk. Of course, we take water quality very seriously and we’re continuing to monitor and reassess this risk whilst working closely with the DWI and following their guidance.
