Data to clarify the landfill role in the case of groundwater quality degradation (Southern Italy)

The data presented in this article are related to the research article described by “How can the role of leachate on nitrate concentration and groundwater quality be clarified? An approach for landfills in operation (Southern Italy)” (Cossu et al., 2018). The data set for this article contains chemical analyses of groundwater and leachate, isotope analysis of groundwater and leachate around a group of landfills located in the municipality of Conversano, close to Bari, the main town of the Apulia Region (Southern Italy). Groundwater samples were collected from eighteen wells. The hydrogeological and chemical study was used to define geochemical features, groundwater and leachate characteristics and to study their potential macroscopic mixing. The land use analysis highlighted quantity and type of used fertilizers permitting to compare these with groundwater in terms of isotopic signature.

Geochemistry of groundwater at the seawater/freshwater interface of the Santa Cesarea thermal springs (south Italy)

Geochemical processes occurring at the seawater/freshwater interface were studied for the aquifer feeding the Santa Cesarea thermal springs, located along the coastal sector of the Salento peninsula (southern Italy). In this coastal area, seawater is moving into the freshwater carbonate aquifer, pushing so inland beneath the freshwater and creating so an extremely active geochemical environment. In the transition zone, the interaction between the freshwater/saltwater and the aquifer rocks could affect the geochemical composition of the groundwater itself, modifying it even profoundly, as discussed in the paper. The geochemical processes occurring at a seawater/freshwater interface are also described together with the chemical composition of Santa Cesarea thermal springs.
