Geochemical, Geological and Groundwater Quality Characterization of a Complex Geological Framework: The Case Study of the Coreca Area (Calabria, South Italy)

Hydrogeochemical characterization and statistical methods were used to investigate the groundwater quality origin of constituents (anthropic or natural) in Coreca area (Calabria, South Italy). is characterized by an articulated geological setting where three main complexes that distinguish Northern Calabria Peloritan Orogen (CPO) outcrop. This complex asset affects mainly exploited for irrigation use. In particular, presence ultramafic rocks (e.g., serpentinite metabasite) promotes release harmful elements such as Cr Ni. studied area, two groups waters identified: Ca-HCO3 strongly controlled interaction with Ca-rich phases limestone), Mg-HCO3 related meteoric water metamorphic units. Statistical elaboration allowed detect, group, a good correlation between Ni (not observed Ca waters) negative Cr, Al, agreement direct low concentrations CaO Al2O3. The concentration major trace has been compared Italian law limit values drinking guidelines provided World Health Organization (WHO). Only samples showed Mn higher than threshold. Furthermore, assessment was carried out using salinity metal indexes. classify resource “excellent good” “good permissible”; nevertheless, problem magnesium hazard found. Lastly, index (MI) calculation revealed <1 almost all samples, pointing overall quality. few value extremely 1, attributable prolonged and/or localized anthropogenic pollution. From general point view, generally except limited areas (and set analyzed) mild exceedance maximum thresholds must be monitored over time. Through multidisciplinary approach, it possible ascertain anomalies hosting not (with exceptions) anthropic processes.
