Short summary

Potential risks of chemical pollutants in water need to be addressed. There is currently a lack of guidance on how to address new/unknown micropollutants and mixing effects. This creates major challenges for the water sector.

Our long-term vision is to establish a new practice for the assessment and management of chemical risks in water to better protect the environment and human health.

The project aims to initiate a cross-sectoral dialogue to map the current state and development needs in the assessment of chemical risks in natural and engineered water systems.

We approach the issue from three perspectives: analytical techniques, risk assessment and regulation. Through these discussions, we will identify gaps and barriers, summarise good examples and propose a way forward to test and implement this new practice.

1. Methods for detecting and characterising chemical pollutants: analytical techniques for detecting unwanted chemical substances in water and their applicability and integration into risk assessment.

2. Chemical risk assessment: current risk assessment methods for chemicals, their implementation, impact of directives and data needs and challenges.

3. Legislation and communication: shortcomings in chemicals legislation, current government and water company practices and visions for future support in chemical risk assessment and decision-making, including how to inform the public.
