This project was part of the EU's 7th Framework Programme (coordinated by Fundación Labein, Spain). Its objective was to develop remediation technologies for soil and groundwater contaminated with chlorinated hydrocarbons, with emphasis on assessing and minimizing side effects of chemical oxidation methods.

Project VaV MPO FR-TI/555. The outcome was software capable of interpreting, balancing, and visualizing site investigation results, as well as proposing, evaluating, and optimizing remediation strategies. The main benefit of the Toolbox is the improvement of the remediation planning process, considering future land use and associated costs to achieve compliance with the intended site use.

This technology was developed in cooperation with DEKONTA as the main partner within a research project co-financed by the Ministry of Industry and Trade of the Czech Republic (project FR-TI1/237). The result is an in-situ remediation method utilizing the biodegradation potential of indigenous microorganisms to treat rock environments contaminated with trinitrotoluene (TNT). The technology’s effectiveness was validated through two pilot-scale applications at a real contaminated site.

The RISCO technology was developed and validated in collaboration with the main project partner, DEKONTA, within the research project VaV funded by the Ministry of Industry and Trade of the Czech Republic (project FR-TI1/244). It is based on the sequential in-situ application of a surfactant and a strong oxidant (activated persulfate). It is particularly suitable for remediating hot spots of groundwater contamination with chlorinated hydrocarbons where a free phase is present. The technology's effectiveness was confirmed through four pilot-scale applications.

The Nano-Bio-Rem technology, developed with funding from TAČR (project TA01021792), is based on the sequential combination of abiotic Cr(VI) reduction using nanoscale iron and microbially mediated Cr(VI) reduction. Laboratory and pilot-scale tests confirmed high efficiency in permanently removing Cr(VI) from groundwater. The technology is environmentally friendly, does not introduce harmful substances into the subsurface, and does not cause long-term adverse changes in the hydrochemical composition or microbiology of groundwater. The project resulted in a validated technology and registered Utility Model No. 28124.

The circulation system enables active and remotely controlled dosing of remediation agents into the rock environment, resulting in more uniform distribution and, ultimately, reduces rebound of contaminant concentrations. It also shortens the time required to achieve target concentrations and reduces the total amount of agents needed. Online monitoring of key parameters and remote system control allows prompt response and increased efficiency of the remediation process. The system’s effectiveness was confirmed through successful application at a site contaminated with chlorinated hydrocarbons. The system was developed with support from the Technology Agency of the Czech Republic under the ALFA 4 program (project TA04021725) and is registered as Utility Model No. 29656.
