To assess the spatial and time trend of salt contamination due to seawater intrusion for Apulian groundwater, a salinity threshold value dividing fresh groundwater from seawater contaminated groundwater is determined. The trend of 0.5 g/l salinity contour line in the period 1981-2003 is analysed. The salt contamination is also characterised whit respect to 17 time series of monthly chlorine concentration, a parameter which can highlight the seawater contamination effects. Data from 1968 to 2001 are considered and compared with rainfall and temperature time series. The increased saline contamination is closely related to droughty years and to the increasing discharge by wells.
