Oropos plain exhibits significant concentrations of Cr(VI) in groundwater. Chemicalanalysis of soil samples show high concentrations of Cr in soils of Oropos plain. Soil fractionationwith liquids of high specific gravity that separate soils into heavy and light fractions andsubsequent chemical analysis of the fractions showed that the heavy fraction has extremely highconcentrations of Cr (11,965 to 15,583 mg/kg). The mineralogical and chemical analysis of thosefractions shows strong evidence of ultramafic rock erosion products. The results support theevidence of geogenic origin of hexavalent chromium in soils and groundwater of Oropos Plain.Management of groundwater in the area would require studies that would delineate theanthopogenic from geogenic contamination.
