CWA on Soil-sediment-water system - Solutions to deal with PMT/vPvM substances
PROMISCES, in collaboration with our sister projects ZeroPM and SCENARIOS, developed a CEN Workshop Agreement focused on the soil-sediment-water system.
This CWA (CWA 18201:2025) addresses challenges related to persistent, mobile, and potentially toxic (PM(T)) and very persistent, very mobile (vPvM) substances, including PFAS, in soil, sediment and water systems.
Solutions from the three Horizon Europe funded projects in the categories of prevention, substitution, monitoring, remediation, co-creation, and hazard and exposure assessments are offered in easy-to-digest factsheets.
Key solutions include new methods for PFAS analysis, risk assessment improvements, and solutions for PFAS removal from various matrices like wastewater, sediment, and sludge. The CWA aims to promote a European circular economy and focuses on five specific routes:
- semi-closed water cycles for drinking water supply
- wastewater reuse for agricultural irrigation
- nutrient and energy recovery from treated sludge for fertilisers
- material recovery from dredged sediment for eco-materials
- groundwater and soil remediation.
The information contained in the CWA is relevant to actors along the various circular economy and PM(T) exposure routes, including researchers, public authorities, water utilities, and solution-developing companies.
