Utvärdering av åtgärdsalternativ för Badöområdet med SGI:s verktyg SAMLA / Risk assessment of remedial alternatives with SGI’s tool SAMLA

Forsgren, Sophie January 2021 (has links)
The purpose of this work was to evaluate remedial alternatives for the Badö area in Uddevalla. Large parts of the area consist of heterogeneous filling and the contamination situation consists of, inter alia; arsenic, chromium, PAH, and petroleum. These contaminations are consistent with previous activities on the area. The evaluation of remedial alternatives was made using Swedish geotechnical institute’s (SGI) multicriteria tool SAMLA in which 5 remedial alternatives were examined. These were either solidification/stabilization or excavation, with various forms of land use possible after completed action. The purpose of this work was also to examine how well SAMLA is suited to be used in risk assessments. SAMLA evaluates remedial alternatives using three sustainability dimensions; environment, social and economy. The remedial alternatives are scored in relation to each other and the option of leaving the area without any measure taken. The results of the evaluation in SAMLA are presented as tables and charts and indicates that an option using excavation and resulting in the area being able to use for housing is rated the highest. In this stage there are more uncertainties using solidification/stabilization, and more investigations in the field are needed to examine the method further. The result concludes that SAMLA is considered user-friendly and relevant to use to shed light on several uncertainties and factors in different time perspectives, but preferably together with different actors involved in the process.
