22 nd Salt Water Intrusion Meeting: Salt Water Intrusion in Aquifers: Challenges and PerspectivesSANTA CESAREA COASTAL THERMAL SPRINGS (SOUTHERN ITALY)M. Polemio, P. P Limoni, L. E. Zuffianò, F. Santaloiam.polemio@ba.irpi.cnr.itIRPI, CNR, Bari, Italy.Abstract. The coastal carbonate Apulian aquifers, located in southern Italy, feed numerouscoastal cold springs and constitute the main local source of high quality water. The group ofSanta Cesarea springs constitutes the unique occurrence of thermal groundwater outflow,observed in partially submerged coastal caves. The spring water is rich of hydrogen sulfide;temperature ranges from 25 to 33 C°. For their properties, spring waters are used for spaactivities from several decades. Hydrogeological spring conceptualisations proposed up nowwere not able to justify water geochemical peculiarities or were not completely confirmed upnow. To reduce these uncertainties, a complex hydrogeological survey has been defined.Geological and structural surveys, chemical and isotopic groundwater analyses, spring andwell discharge measurements, well loggings, multi-parameters spring automatizedmeasurements, and cave explorations are ongoing. All available data have been used toimprove the knowledge of groundwater flow system, including the valuable deep aquifer, theorigin of the thermal waters, and to investigate the possibility of using low-enthalpygeothermal fluids to fulfil the thermal needs of the town of Santa Cesarea Terme.Keywords Carbonate aquifer; sulphur groundwater; thermal springs, coastal aquifer,Apulia, Italy1. INTRODUCTIONThe Santa Cesarea spring group is located in the town of Santa Cesarea Terme (terme is theItalian translation of spa), a touristic villages of Salento, the south-easternmost portion of theApulia region (Southern Italy; Figure 1). These springs are characterized by sulphureous andwarm waters (Zezza, 1980). Their special groundwater characteristics were discovered inancient times and were described by historians, such as Aristotele (III century BC), Strabone,Claudiano, Leto (I, III, and XV century respectively), as well as by recent authors. Springwater characteristics are almost variable as consequence of tides (Visintin 1944; Zezza 1988).In particular, the ion chloride content increases with tides, while the hydrogen sulphidecontent and temperature decrease. The paper presents some preliminary results of an ongoingresearch project of the (Italian) National Research Council, aimed at the assessment of thegeothermal potential of regions located in southern Italy (VIGOR Project).2. GEOLOGICAL AND HYDROGEOLOGICAL SETTINGSThe Santa Cesarea group is represented by four main springs, located in Salento Peninsula,along about 500 of the Adriatic coast, where the outcropping limestone of the Apuliancarbonate platform is dissected by a series of NO-SE faults dipping towards East and West.101
