Sustainable remediation of contaminated sites

During INSURE pilot areas in Sweden, Finland and Latvia have been investigated and tested for the function of sustainable remediation alternatives. In this part of the project we have also done remedial alternative selections processes, risk valuation and cost effective analysis.

Pilot areas

The pilot areas are located in Motala, Sweden, two pilot sites in Valmiera, Latvia and Janakkala, Nastola, Virrat, Loppi and Karjaa, Finland. Each pilot area has different historic contaminants. By testing suitable sustainable techniques for each site knowledge and experience have been developed within the project regarding what technique was suitable at what type of site. Soil from pilot areas was simulated in laboratory conditions. This has resulted in a tool for evaluation of sustainable remediation techniques and when to apply them. Example of techniques that have been tested is biostimulation, electro-kinetic pumping, fenton reaction and phytoremediation. To know more about the pilot areas you can go to the page Pilot areas.


Below you can find out more about the results connected to the pilot areas and the methods used.

Investigation strategies for pilot areas

All pilot areas have a investigation strategy. The strategies were made in the beginning of the project and tell more about what activities the partners were planning on each area.

Site investigation reports for pilot areas

After investigations on the pilot areas the results have been reported in site investigation reports.

Remedial alternative selection process and risk valuation 

In the process with selecting suitable techniques at the different pilot areas remedial alternative selection processes and risk valuation have been carried out. During the remedial alternative selection process different type of remediation techniques are evaluated. In the risk valuation process the different remediation alternates are evaluated regarding for example environmental-, economical-, and social aspects. Focus in this project has been to include and especially consider sustainable remediation techniques and climate change. Below you can find out more of the results from the process of selecting techniques.

Cost effectiveness analysis 

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 have been performed to give a view on correlation between sustainable remediation, prospective environmental impact and the possibility for city development.
