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

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.

This work package includes two separate but linked activities which are to be combined under a single Lot. The first component relates to delivering a series of desk studies for sites of concern. The second involves progressing one of these desk studies, where historic evidence has already led to formal site determination and designation under Part 2A of the Environmental Protection Act 1990, into an intrusive site investigation.

To build on the outputs of Phase 3 which, using the results generated by the GIS model, aimed to categorise and quantify the number of potential problem PFAS sites across England. To assess the recommendations from this Phase 3 task, and develop an approach and ultimately deliver a report, detailing the nature of the PFAS problem across the Country together will a mechanism for deriving costs to highlight the financial scale and burden of the problem.
