Groundwater circulation remains local in small crystalline aquifers. Transit times are large despite highly local flow. Groundwater distance distribution decreases at downslope sites. An indicator of groundwater table controls at the small catchment scale is proposed. Groundwater quality should be investigated at local scales in shallow aquifers.
