Thermal waters of S. Maria is Acquas is located near Sardara along the NE border of Campidano graben. This area includes fivr springs with temperature ranging from 33°C to 60°C; they show sodium-bicarbonate-chloride chemical composition with salinity of 3.4 g/l. Both geophysical and geochemical methods were employed to evaluate quality and quantity of thermal resources. Geophysical investigations by electrical methods allowed to establish aquifer characteristics in its terminal part while detailed chemical composition, deep temperature and mixing with cold groundwaters were evaluated by geochemical data. Hydrodynamic parameters were found by pumping tests using Jacob method. No interference was observed among different springs in agreement with the geophysical and geochemical model.
