Residents of Longyearbyen in Svalbard have been told not to drink tap water due to heavy metal contamination linked to thawing permafrost, a consequence of climate change.
Longyearbyen, a remote town in Svalbard, relies on a dammed lake called Isdammen for its main drinking water supply. Rising temperatures have caused permafrost to thaw, exposing bedrock that leaches heavy metals into the water. Scientists attribute the contamination to the combination of thawing permafrost and the region’s geology, which includes shale rich in pyrite.
The municipality first alerted residents after manganese levels in the water were found to be 25 times higher than recommended. Emergency measures, including the provision of purified water from a local brewery, were implemented. Although manganese levels have since decreased, other contaminants such as sulphate and nickel have also exceeded safe limits, keeping the drinking water ban in place.
Why it matters
The contamination forces residents to rely on temporary water sources like the brewery-filtered tank.

What to watch
Watch for the local brewery's continued role in providing filtered water through the temporary tank.
