PFAS Risk Screening Project (Phase 4)

Tender description

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. Polyfluoroalkyl and perfluoroalkyl substances (PFAS) are a broad group of synthetic fluorinated organic chemicals which are extremely persistent in the environment. Some are bio-accumulative and toxic, and/or highly mobile. PFAS are a group of more than 4,700 man-made chemicals (OECD, 2018), the two most well-known of which are perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). This procurement outlines our intention and approach to procure the following three work packages through an open competition, with a sub lot for each package of work. 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
