AB Nitrate pollution in the Plana de Vic aquifers has presently reached very high levels, which pose enormouslimitations to its use. The origin of nitrate is mainly caused by manure application as fer tilizer. In this paper,we present a hydrodynamic scheme of the Plana de Vic aquifer system, based on potentiometric data andnitrate concentrations obtained through a monthly monitoring effort of a 80 well database. The responseof those wells to the recharge that ended a severe drought period allows us to depict differenthydrogeological behaviours between surface and deep aquifer levels. We conclude that a mixing processoccurs in this multilevel leaky-aquifer system facilitated by the uncasing of most of the wells. Therefore, adeficient exploitation of the aquifer is seen as an additional cause for the spreading of nitrate
