Caractérisation hydrogéologique d'un aquifère en socle fracturé : Site de Ploemeur (Morbihan).

Abstract : In Brittany, tap water production is assured at 20% with mainly pumped groundwater in fractured basement. Because of the geometry of fractured network and hydraulic properties the productivity of Briton aquifers is generally limited (400 to 1000 m3/h). At Ploemeur(Morbihan) an important groundwater reservoir is exploited as main tap water supply since June 1991 at an average pumping rate of 3000 m3/h. The main characteristics of this aquifer are 1) important water inflows localised in fractured pegmatites and 2) good pumped water quality ([N03]
