Notice Information

Notice Title

PFAS Catchment Investigations

Notice Description

Severn Trent are looking to understand sources of PFAS in surface water feeding Whitacre and Church Wilne WTW with a view to understand risk at our WTW now and in the future. We are also keen to explore what is controlling variation and concentrations, and what mitigation actions may help to reduce PFAS levels in these catchments and their potential effectiveness. This information will be used to plan the necessary level of PFAS removal required at water treatment works in these catchments now and for the future, and work towards less reliance on energy intensive removal / destruction techniques. The work also aims to further develop our stakeholder engagement activity, fulfilling commitments in DWI guidance as well as working with stakeholders to reduce sources in catchment. The objectives of the work are to: 1. To understand where PFAS of concern are originating from considering both current and historic activities in our catchments. 2. To understand how PFAS levels may change in the future. 3. To understand what is controlling PFAS concentrations. 4. To review what mitigation options are available to reduce PFAS levels and how feasible / effective they could be in our catchments and at what cost. 5. Support ST's stakeholder engagement activity
