PFAS Risk Screening Project, Phase 4, Work Package 2 - Development of Best Practice Guidance

The primary objective is to develop a reference guide aimed at those involved in the regulation of sites of concern due to the impact, or potential impact, from PFAS and associated chemicals. Staff can refer to the guide when faced with sites highlighted under voluntary schemes, regulatory regimes, or pollution incidents. The guide will provide background to the problem, the nature and characteristics of these chemicals, and the tailored approach necessary to best assess the risk, apply regulatory controls and ultimately implement mitigation measures (if necessary). The step-by-step guide will adopt the classic land contamination evaluation approach, indicating how at each stage of site assessment the site evaluation strategy should be conducted when considering contaminants of this nature.
