After two large-scale applications in Spain and Portugal, groundwater samples were taken for more than 6 months. These samples, along with those collected before the application were analyzed to determine the concentration of the contaminants in liquid phase, and to assess the effectiveness of the application of REGROUND technology in these sites.

Filtered and unfiltered groundwater samples were analyzed using  ICP-MS/OES, UV-Vis spectroscopy and OC-analysis at Friedrich-Schiller-Universität Jena. Currently these data are being analyzed by the consortium, and are being compared to the results of laboratory tests. The early analysis seems promising results on achieving the remediation goals in both sites.
