CHARM - Chromium in Asopos Groundwater System: Remediation Technologies and Measures

charmAsopos river basin is located at the Region of Sterea Ellada and the River Basin District of East Sterea Ellada (RBD07). The groundwater system of Asopos presents high concentrations of chromium and hexavalent chromium and as a result there is an increased public concern, since part of the groundwater is used for water abstraction for human consumption and most of it for irrigation purposes. One interesting issue related to the groundwater quality of the specific groundwater system is related to the possible increased natural levels of chromium in the water, which makes it a more difficult task to tackle, with respect to the determination of rational threshold values (TVs) and proposal of appropriate remediation technologies and measures. The main objectives of the project are:

 

  • Evaluation of the effect of soil and groundwater properties and their contribution to high Cr (VI) natural background level (NBL)
  • Evaluation of the effect of high NBL (natural background level) of chromium and hexavalent chromium to the determination of the respective TVs.
  • Development of a rational methodology for the determination of threshold values (TV) considering the guidelines of Annex II of the GWD that could be adopted and applied in other parts of Greece and the EU.
  • Identification of activities related to pollution with chromium and estimation of the generated loads and their transport until entering the aquatic environment.
  • Demonstration of different technologies for remediation of groundwater bodies experiencing high concentrations of chromium and hexavalent chromium.
  • Establishment of a programme of measures (PoM) for the river basin of Asopos, which will involve the implementation of the most efficient technologies for chromium removal, supplementary administrative and legal instruments, for which active participation of stakeholders is anticipated.
  • Achievement of a social agreement on water resources management and protection.
  • The exploitation of European best practices and know-how on water resources management with emphasis to the implementation of the Groundwater Directive.
