Assessing groundwater quality: a global perspective
This perspective paper by the Friends of Groundwater (FoG) group aims to give a compelling argument for the importance of groundwater quality for human development and ecosystem health. It also provides a global overview of the current knowledge, with focus on data coverage, gaps and technological advances. It is a building block towards a future global assessment of groundwater quality as part of the United Nations Environment Programme (UNEP) World Water Quality Assessment (WWQA).
