ABSTRACT: Groundwater monitoring gives information to planning and sustainable water use. Also, it allows detecting changes from anthropogenic activities and treats these effects in able time to do not turn into potential damages and risks in the water resources exploitation. Aquifer outcrop areas have natural vulnerability of water contamination. The aim of this work is to analyses groundwater quality monitoring data in an outcrop area of Guarani Aquifer System (GAS) in Brotas/SP-Brazil. We selected ten wells located in different land uses (pasture, reforestation, sugarcane, citrus and Cerrado vegetation) with level, electrical conductivity and temperature daily monitored during one year (2012-2013). Comprehend hydrological processes in a monitored basin in detail gives methodological basis for studies in other recharge areas of the GAS and contributes for a sustainable groundwater management, combining human consumption, agricultural production and environmental quality.

RÉSUMÉ: La surveillance des eaux souterraines fournit des informations pour la planification et l'utilisation durable de l'eau. En transforment pas en dommages potentiels et les risques de l'exploitation des ressources en eau. L'objectif de ce travail est l'analyse des données de surveillance de qualité des eaux souterraines dans une zone d'affleurement du Système Aquifère Guarani (SAG) dans Brotas / SP-Brésil. On a sélectionné dix puits situés dans différentes utilisations des sols température surveillés tous les jours pendant un an (2012-2013). Compreendre les processus hydrologiques dans une bassin surveillé dans une détaillée fournira de bases métodologiques pour des études des autres zones do SAG et contribuer à la gestion durable des eaux souterraines en accordant avec la consommation humaine, la production agricole et la qualité de l'environnement.
