The purpose of this study was to survey and risk evaluate 9 out of 23 disused landfills in Vilhelmina municipality, Västerbotten, Sweden. The study is based on MIFO methodology which is developed by the Swedish Environmental protection agency, EPA. The MIFO methodology is divided into two phases and this study deals with phase one. The intended use for MIFO is to evaluate the risk of these nine disused landfills and assess polluted soil and water areas. The results of the study are described for each landfill with respect to degree of pollution, the toxicity of the pollutants, conditions for distribution from soil to groundwater, soil to surface water, and surface water to sediments. The conclusions of the risk classification indicate that one landfill ended up in a class 2 and the other landfills ended up in class 3. Two of nine landfills are in need of action while the others need a control program to continuously monitor the status of the landfill. Metals were analyzed from soils of three landfills, and although these landfills were leaching, no levels exceeded the guideline value for land. Pollutants have been analyzed in surface water and groundwater of two of the landfills, but high detection limit and small sample sizes prevented accurate comparisons with available guidelines. More samples have to be analyzed to assure that guidelines are not exceeded. No acute environmental damages have been noted in this study, but in the future some of the landfills may need to be inventoried.
