If soil becomes so polluted that it can be assumed to pose unacceptable risks to health, theenvironment or natural resources, remedial action must be carried out. In 2006, aninventory study was compiled by the Swedish Environmental Protection Agency. The resultsshowed that more than 50% of the projects were completed via excavation of thecontaminated masses. Now 15 years later, the purpose of this report is to study remedialactions completed in Sweden over a 12-year period (2010–2021) and try to investigate howthe distribution of the methods used in practice reflects the development of knowledge onremediation. All 290 municipalities in Sweden were contacted and over 1000 reports ofremedial action were collected. Out of all 1000 reports only 114 was used due to the smallsize and short time allocated for this study. The result showed that in 113 of the 114 cases theremedial action was shown to be excavation, and, thus my conclusion is that excavation stillaccounted for the majority of remedial action methods used. It is not possible, based on theresults in this report, to determine exactly which factor or to what extent each factorcontributes to the majority of ex-situ remediation in Sweden. Probable reasons are the highcommercial availability of excavation remediation and traditions that exist in the industry,which means that it will not be possible for in-situ methods to establish themselves andbecome financially sustainable.
