Perturbazioni antropiche irreversibili delle caratteristiche chimico-fisiche dell'acquifero sottostante la città di Bari

Abstract

During the last decades the coming up of new technologies as well as new needs has increased the interest in groundwater likely to be found in aquifers below massively urbanized areas, even where the groundwater quality does not permit any kind of use. Such an assumption has led to study the characteristics of chemical-physical degradation of groundwater flowing in the aquifer outcropping where the town of Bari is located. Surveys proved that significant groundwater alterations are mostly due to massive widespread water discharges and sewage releasing in the subsoil. Air-conditioning systems which often use groundwater for heat exchange play an important role. In order to assess the spatial effects of such heat exchanges, mostly unauthorized, numerical simulations were realised.
