Through Advances in Assessments, Water Quality Modeling, and Water Supply Management Geogenic contamination of groundwater is a global public health crisis and is threatening the success of the UN SDG6. The session includes abstracts that investigate geogenic (‘naturally occurring’) contaminants from the aspects of biogeochemistry and transport, water resources management, water treatment, community water planning, contaminant prevalence and climate change, socio-economic impacts, and the impact of compromised water resources on public health. We also welcome advances in modelling approaches.
