A multitracing approach for the protection of groundwater resources of Simbruini Aquifer, Central Italy

This paper presents the results of some studies that, starting from lots of information about the geological and hydrogeolo gical properties of the north-west part of the Simbruini Mounta ins (carbonatic massif), and by a multitracing approach have determined the location of the most important recharge areas of this basinoInfact the multi tracing approach it is used for carrying out complex hydrogeological problems by the comparison of different chemical elements present in groundwaters . In this case study, the most interesting chemical water constituents of the carbonatic aquifer were conside red: calcium, magnesium, strontium and hydrocarbon. Concurrently isotopical analysis of water composition was carried out, identifyng Deuterium and 18-0xigen, since these isotopes can contribute to determining the recharging areas of the groundwaters coming out at the considered springs.
