Résumé
Groundwater is a vital resource and a conveyor belt for dissolved and particulate matter. It is a crucial component of local, regional and global water cycles, and the quality of groundwater is inextricably linked with global environmental and social viability. The GQ10 conference focused on the need to manage, sustain, repair and protect groundwater quality under rapidly changing climatic and global conditions. The aim was to build a bridge between contaminant hydro(geo)logy to other scientific disciplines and to society.
