Knowledge of the environment, sustainable practices to the territory

Mapping the vulnerability of aquifers to pollution by highlighting those areas mostly exposed to contamination, for medium to long-term planning of water use.

Main applications

Thematic maps of the vulnerability of aquifers to pollution are intended to:

  • provide information on the suitability of the various sectors to accept settlements or activities;
  • highlight type and extent of risk associated to alternative options for the same site;
  • locate and establish a hierarchy of incompatibilities respect to the status quo, in order to implement measures to mitigate the risk;
  • contribute to identify environmental constraints and operating conditions of certain activities to be implemented by means of urban planning.

Vulnerability is the only "natural" (or intrinsic) parameter of the system: maps of inherent vulnerability of a certain area are essential during planning; the inherent vulnerability is associated with the presence, location, topography, hydrogeology and type of the so-called "centers of danger".

The analytical formulation of the Integrated Vulnerability, on a qualitative basis, is as follows:

Risk (Integrated Vulnerability) = hazard (Centers danger) * Vulnerability (intrinsic vulnerability) * Value (Importance aquifer)

It shows that the risk (probability) of an undesired event (in this case, the contamination of a flap by a pollutant) is a function of the hazard event (toxicity, spilled oil, mobility in the environment), the vulnerability of the aquifer and the value of the assets (use of groundwater for drinking water, population served, possibility of alternative sources).
