The aquifer of interest is the Brussels Sands formation in Belgium. Approximately 29, 000, 000 m 3 of groundwater per year is pumped from this aquifer. The Brussels Sands display a complex geological heterogeneity and anisotropy that complicates pumping test interpretation, groundwater modeling and prediction of pollutant transport.
