Summary:This study deals with a chemical survey (major ions and Li+, F-, Br-, NO-3) on water samples of the Telese thermal spring emerging in the Benevento area, collected from April 1998 to April 1999 with a circa monthly frequency. The study was carried out in order to verify (and then investigate) possible variations in the chemical composition of the spring. Water samples were systematically of calcium-bicarbonate type, with small fluctuations of outlet temperature (20.05±0.23°C), pH (6.23±0.16) and TDS (2415±35 mg/l). The concentrations of major ions kept nearly constant, excepting for SO42- ion. The variations of the latter may be largely controlled by fluctuations in the supply of endogenic H2S. All analysed waters are saturated or oversaturated relative to calcite and dolomite, and undersaturated relative to gypsum and fluorite. The higher saturation indices of the water samples relative to calcite and dolomite observed during summer 1998 may be interpreted in terms of the lowered rainfall during the dry season, and then reduced flow of the recharge and lower supply of CO2 to the feeding aquifer at depth.
