Discharge conditions and variations of the main hydrological parameters of some coastal Apulian springs relating to sea water influence of groundwater

With the aim of examining closely the hydrological equilibrium of the aquifer flowing in the Murgia carbonate masses, investigations on the main Murgian coastal subaereal springs located on both Ionian versant and Adriatic one were carried out. The observations have mostly related to hydraulic features of outflow and ,the chemical-physical ones of the flowing waters. Surveys gave,the possibility of characterizing springs according to the coastal versant they flow owing to the different hydrological regimen,the different discharge temperature correlations and saline content values which do not exceed 4 g/l for Ionian spring waters while for the Adriatic versant ones they can even be of the order of 15 g/1. In the end, a completely different assumption about present sea waters involving in the saline contamination processes of the aquifer can be pointed out. ('|) lstituto
