Abstract
Two different cases of Cr(VI) contaminated ophiolitic aquifers are presented herein. The first is located at Vergina (Northern Greece), where the maximum Cr(VI) concentration measured was 64μg/L, being one of the highest geogenic concentrations recorded globally in areas with similar geological background. The second case is located at Inofyta (Central Greece), a makeshift industrial area, where the maximum detected Cr(VI) concentration exceeds 10,000μg/L, indicating clearly anthropogenic activities as the main source. Although for the Vergina aquifer, area-wide institutional measures and in some cases pump and treat systems might be sufficient to ensure a safe water supply for domestic and agricultural use, this is not the case for the contaminated aquifer of Inofyta. There a comprehensive remediation scheme should be properly implemented adopting, however, realistic remediation targets, that should also take into account the geogenic contribution to the high Cr(VI) groundwater concentrations measured.
