Between 1928 and 1976, a sawmill was located at the shore of Brosjön in the small village of Ydrefors in Ydre municipality in eastern Sweden. During the last ten years of the sawmill's operating years, a product namned Servarex was used to prevent fungus attacks of the timber. Servarex caused a contamination of dioxins in the soil, as well as pentachlorophenol (PCP) in groundwater. In the main study, the sampling revealed concentrations of dioxins (610,000 ng/kg) that was the highest detected

The dioxins contaminated soil with levels above the hazardous waste limit (15,000 ng/kg) is not allowed to be deposed in Sweden. The soil was therefore successfully treated with chemical oxidation at RGS 90:s facility in Norrköping, Sweden.
