The IWA Specialist Group “Metals and Related Substances in Drinking Water (METRELS)” is a group with a mission to work for an improved control of metals and related substances in drinking water and to contribute to human health and well-being of the society. During the past one year, the SG-METRELS is also actively engaged with activities linked with implementation of the IWA Strategic Plans for: i) developing Water Wise Cities and ii) the UN Sustainable Development Goals for drinking water. Aligned with the strategic plans of the IWA, this Sprinter Meeting we have an ambition to focus our discussions on:

• Metals, metalloids and co-occurring contaminants in drinking water sources at catchment scale – impact on quality and health risks
• Technology to develop best practice for drinking water treatment for metals, metalloids and co-occurring contaminants
• Potential avenues for transfer and dissemination of knowledge – bridging the gaps in safe drinking water access.
• Sharing practitioner experiences across cross-sectoral stakeholders in water and environmental health sectors
• Critical determinants for implementing the drinking water safety plan from perspectives of IWA Water Wise Cities and Sustainable Development Goals.
