Groundwater flow paths in a glacially affected flat area in the Netherlands

Dijksma, R.; Menkveld, S.H.; Bier, G.; Osterhof, A.T.

Summary

Well field Garyp is abstracting deep groundwater from fluvioglacial sediments, which are covered by glacio-lacustrine clay. This drinking water abstraction is hampered by rapid salinization of the abstraction wells. A detailed ground-water modelling study was done, to reveal the water pathways and the groundwater-surface water interaction. It was concluded that shutting down wells, nor reducing abstraction rates or reduction of well screen depth would result in significantly less abstracted water from brackish layers.
