This document defines best practices, solutions, and guidelines concerning the management of (very) persistent ((v)P), (very) mobile ((v)M) and toxic (T) (PMT/vPvM) substances, not only assessing their behaviour in the soil-sediment-water system but also their possible prevention at source as well as end-of-pipe solutions. These solutions are clustered into categories (e.g. prevention and substitution, remediation measures, co-creation and prioritization, monitoring, hazard and exposure assessment) in order to reach various stakeholders working within the soil-sediment-water system. As part of the categorized solutions, a special focus is placed on the following five circular economy routes:
a)  Semi-closed water cycle for drinking water supply
b)  Wastewater reuse for agricultural irrigation
c)  Nutrient and energy recovery from treated sludge for fertilizers
d)  Material recovery from dredged sediment for eco-materials
e)  Groundwater and soil remediation to protect water cycle
This document is applicable to researchers, public authorities, problem owners, NGOs, water utilities, chemical manufacturers and users, soil/brownfield actors or companies developing market-ready solutions.
