The aim of the project is to demonstrate the use of multi-criteria analysis (MCA) in evaluating management and remediation alternatives to access their overall impact, with focus on soil function (ecosystem services and goods) and sustainability. As some aspects of soil function cannot be easily quantified in monetary terms, MCA offers a complementary approach in comparison to cost-benefit analysis (CBA). Maintained soil function is a key parameter in sustainable developments and the proposed project will demonstrate a method for including soil function and related geographical, cultural and soil use aspects of soil function into MCA. The project is based on studies of a few representative polluted sites provided via the EURODEMO network, and includes a range of conventional and innovative remediation technologies and strategies, including soft, low cost on-site, harder hard on-site, and off-site alternatives. The impact of the remediation strategies on soil function is assessed and used as input during the MCA. The analysis utilizes recent results regarding baseline levels for organic and metals pollutants and contaminants as well as input on fate of pollutants and contaminants on a regional scale (e.g. through the Snowman PERSPEC and the FP6 AquaTerra projects).
The project is carried out at the Division of GeoEngineering, research group Engineering Geology.
