Evidence of contamination by domestic sewage and salinization of waters were shown to occur in a localized manner. The occurrence of reduced iron in well waters was generalized. Indices of vulnera-bility of the aquifers of various sub-areas are presented.

In this case, the sorption phenomena in soils play a key role, which determines the transport of toxic compounds to receiving waters, and consequently their fate. This chapter describes the importance of sorption me

In the light of these two aspects a new generation of geochemical models of coupled chemical reactions and solute transport has been developed. An equilibrium condition is not assumed a priori in these models. Despite its importance, validation of thes
