Norrbyskär: Contaminated historical environment freed from toxins

In the early 1900s, the island of Norrbyskär in the Swedish municipality of Umeå was the site of a sawmill whose operations spread toxic compounds known as dioxins over large areas. The island, which is regarded as having important cultural-historical values, is now to be remediated. Sweco has been commissioned to examine the ground and propose remedial measures to clear it of toxins.
