PFAS Risk Screening Project Phase 4 – Work Package 2-4

The overarching PFAS Risk Screening Project, now in its fourth phase, aims to assess and tackle the risks arising from a group of “forever chemicals” which are contaminating soil, groundwater and surface waters and pose a risk to human health. Increasing awareness of the widespread presence of PFAS in environmental media has heightened regulatory concerns about their potential risks to human health and the environment. A recent evidence review by the EA has identified large data gaps in relation to the uses, sources, and mass emissions of PFAS in the UK. This report recommends further research and investigative work to evaluate the sources, both current and legacy, that are contributing to the widespread nature of this family of contaminants. This objective of this procurement is to source up to three services contracts with a consultant(s) who can deliver the following Work Packages: WP2 - Lot 1. Development of Best Practice Guidance WP3 - Lot 2. Detailed Assessment of Potential PFAS Problem Sites: o In-depth desk studies of x10 highlighted problem sites o Site investigation of x1 prioritised site (Grosvenor Chemicals) WP4 - Lot 3. Economic Appraisal
