Tap water no longer drinkable in Norwegian town as climate-related thawing releases heavy metals
Warning for other Arctic communities as residents told not to use water in Longyearbyen in Svalbard, one of the fastest-warming places in the world
TL;DR
- Longyearbyen, Svalbard, has banned tap water consumption due to heavy metal contamination.
- Thawing permafrost and shale bedrock containing pyrite are leaching metals like manganese into the water supply.
- Manganese levels were found to be 25 times higher than recommended, with subsequent detection of elevated sulphate and nickel.
- Prolonged exposure to high manganese levels can cause neurological problems, especially in children.
- The municipality is considering expensive solutions like a new water mains supply or filtration and desalination plants.
- Scientists warn this event may be a sign of future freshwater contamination issues in other Arctic communities due to climate change.
