Assesses groundwater and surface water quality in a coastal aquifer, revealing salinization as the main threat to water resources.

The study aims to assess the quality of groundwater and surface water in the Metaponto coastal plain and identify factors affecting degradation.
Conducted seasonal sampling of groundwater and surface water over one year
Analyzed for major ions, trace metals, stable and radioactive isotopes
Utilized hydrochemical diagrams and multivariate statistics to interpret data
Examined seawater fraction and ionic deviation to understand salinization processes
Electrical conductivity varies from freshwater (<1,000 μS/cm) to highly saline (>10,000 μS/cm) in coastal areas.
Hydrochemical facies transition from Ca–HCO3 inland to Na–Cl dominance near coastal regions.
Stable isotopes indicate meteoric recharge with enriched values suggesting evaporation and saline mixing.
Heavy Metal Pollution Index indicates low metal contamination levels despite elevated salinity.
Paleo-groundwater found beneath the coastal aquifer, highlighting different age strata.
