Boron isotope composition was used to identify boron sources in groundwater in the eastern part of central Italy, on the west side of the lower alluvial plane of the Pescara river, a few kilometres from the coastline. This area was characterized by two possible boron sources: human activity and a geogenic source.
A geochemical assessment of groundwater beneath a municipal solid waste landfill site in Central Italy was carried out using a hydrogeochemical and isotopic approach. The aim of this study was to verify the quality of groundwater using major ions, trace elements and boron isotopes as tracers of contamination due to the presence of the landfill. Results obtained show that Fe, Mn, Cr, Ni and B present high values in groundwater located downgradient from the landfill. With boron isotopes, it is possible to identify whether a contamination source is anthropogenic and/or geogenic.
