Abstract
The Fkirina plain located at the southeastern end of the Wilaya of Oum-El
Bouaghi, on the edge of the Constantine high plains covering an area of 650 Km
2
,
represents a priority economic resource because it is used in areas of irrigation and
domestic consumption. The area of the aquifer is mainly occupied by agricultural
areas characterized by an increasing use of chemical fertilizers, in addition to
industrial discharges, which represent a permanent risk for the quality of the
groundwater.
The study of the vulnerability to pollution of this layer has been carried out by
applying standard DRASTIC and SI methods in a GIS environment.
The comparison of the vulnerability maps obtained shows that the results are very
different in terms of recovery rate, but that they have a degree of similarity in the
space. At the level of the representation of the vulnerability, the SI method makes it
possible to obtain a finer information.
