Nastola
Villädhe/Nastola was one of University of Helsinkis test sites in Finland. The contaminant was oil and the method tested was biostimulation with electro-kinetic pumping.
WP T1 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
As the map to the right shows 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. Example of techniques that have been tested is biostimulation, electro-kinetic pumping, fenton reaction and phytoremediation.
One part of INSURE have been to use pilot areas to investigate and perform tests of different remediation methods. Some pilot areas that were planned to use in the beginning of the project were not as contaminated as predicted and have been replaces with others.
Pilot areas in Finland
Virrat
This was the test site for the partner Populus Oy. Since Populus left the project in 2018, University of Helsinki have been taken over the responsibility of the pilot test. The primary contaminat is oil hydrocarbons but there are also heavy metals.
Karjaa
Site Karjaa was one of University of Helsinkis (UHEL) pilot areas in Finland. Karjaa was included late in the project. The main contaminant is oil.
Loppi
Site Loppi was one of Univeristy of Helsinkis pilot areas in Finland. This site was included late in the project. The main contaminants are oil hydraocarbons and volatile organic compounds (VOC).
Janakkala
Janakkala was one of University of Helsinkis (UHEL) test sites in Finland.
Pilot areas in Latvia
Gaides iela, Valmiera
The pilot site of Vidzeme Planning Region is called Gaides iela and is located in Valmiera, Latvia. The former pilot site – Krustmali was investigated but turned out not to be as contaminated as expected.
Territory 9 Dzelzcela Street, Valmiera
The pilot site of Vamiera City Council is called Territory 9 Dzelzcela Street and is located in Valmiera, Latvia. The area is contaminated with heavy oil.
Krustmaļi
Krustmaļi was the former test site for Vidzeme Planning Region in Latvia. Samples taken in 2012 indicated that the area was contaminated with pesticides.
Pilot areas in Sweden
Motala södra stranden
“Södra stranden” is a part of Motala with a very attractive location beside the second biggest lake in Sweden and closeness to both the city center and the nature. Today, the area is characterized primarily by its history as an industrial area in the 20th century, as well as its link to boat activities.
Below you can find out more about the results connected to the pilot areas and the methods used. All reports and articles written about the pilot areas during the INSURE project are linked below.

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.
