Question
To ask the Scottish Government what discussions it has had with Scottish Water regarding the utilisation of technologies for the removal of perfluoroalkyl and polyfluoroalkyl substances (PFAS) from water.
Answer
In line with the Public Water Supply (Scotland) Regulations 2014, Scottish Water is required to carry out risk assessments to assess the likelihood of the presence of the most widespread PFAS compounds in its drinking water supplies. Where risk is identified, controls must be determined. It is a matter for Scottish Water to decide what treatment technology is necessary, however, the Drinking Water Quality Regulator has provided guidance on the types of treatments that can be effective in removing PFAS from drinking water.
The DWQR is participating in a UK wide research project on the effectiveness of different treatment processes for the removal of PFAS that is led by Cranfield University; this research is due for completion by June 2024.
