WP T1 Sustainable remediation of contaminated sites

During INSURE six pilot areas will be investigated and tested for the function of sustainable remediation alternatives.

The six pilot areas are located in Motala (Södra stranden), Sweden, two pilot sites in Valmiera, Latvia and Janakkala, Nastola and Virrat, Finland. Each pilot area has different historic contaminants. By testing suitable sustainable techniques for each site knowledge and experience will be developed within the project regarding what technique is suitable at what type of site. Soil from pilot areas will be simulated in laboratory conditions. This will result in a tool for evaluation of sustainable remediation techniques and when to apply them. Example of techniques that is planned to be tested is biostimulation, bioaugmentation, electro- kinetic pumping, increasing bioavilibility using biosurfactants, fenton reaction and phytoremediation.

In the process with selecting suitable techniques at the different pilot areas remedial alternative selection processes and risk valuation will be carried out. During the remedial alternative selection process different type of remediation techniques will be investigated. In the risk valuation process the different remediation alternates are evaluated regarding for example environmental-, economical-, and social aspects. Focus in this project will be to include and especially consider sustainable remediation techniques and climate change.

In development areas with contaminated sites, costs for investigations and remediation can often be crucial in the investment analysis. During the project cost effective analysis will be performed to give a view on correlation between sustainable remediation, prospective environmental impact and the possibility for city development.
