Abstract: The National Institute of Water and Environment (INA) has defined an institutional program to develop a comprehensive and holistic analysis about the groundwater elevation in the Greater Buenos Aires urban area. A correct diagnosis of the diverse processes involved is provided, analyzing the natural and anthropogenic factors and the possible countermeasures, all in the frame of sustainable development. The diagnosis objectives are: the identification of the factors to act on the free groundwater level variation, the responsibility of each variable into the process and the location of the more affected regions. The action objectives are: the generation of actions for information and diffusion of the problem and the proposal of remediation measures in a short period. The activities proposed for this program have the goal to analyze the influence of: the change of pluvial precipitation in long time scale, water importation to other regions by the water distribution system, the water losses in the distribution net, the high water volume for inhabitant, the scarce area served with wastewater system, the elimination of private water wells for families and industries and the closure of the groundwater public provision system. A study case was carried out for the municipality of Lomas de Zamora, one of the more damaged regions because the unconfined groundwater level comes to the land surface. This zone was considered by the government as in "hydrological emergency".
