"Drink Tap Water Without Knowing the Risks, and You're in Trouble"... Climate Change Puts This Country's Drinking Water Supply on 'Heavy Metal Alert'

Manganese levels reach 25 times the limit; nickel exceeds recommended levels
Metals from bedrock seep into water as permafrost thaws

As climate change melts the permafrost, a Norwegian Arctic settlement has been left unable to drink its tap water. As the frozen ground thaws, heavy metals in the rocks are leaching into the drinking water supply.

According to the British daily The Guardian on October 19, residents of Longyearbyen, the largest settlement in the Norwegian-administered Svalbard archipelago, have been told by authorities not to drink tap water.

Longyearbyen's main drinking water source is the so-called "Ice Pond," a lake about 2.5 kilometers long formed when the flow of a river was blocked by an earthquake, volcanic activity, a landslide, or another event. However, rising temperatures are thawing the permafrost and exposing bedrock, allowing metals to enter the lake. The area is known to be warming five to seven times faster than the global average.

Associate Professor Marjolein Vere of the University Centre in Svalbard explained that the water supply is being contaminated by the interaction between thawing permafrost and shale bedrock containing pyrite. Acidic substances produced as the pyrite oxidizes dissolve heavy metals in the rocks, carrying them into the waterways.

In September 2025, the municipality detected manganese in the water supply at a level about 25 times the Norwegian public health authorities' limit of 50 micrograms per liter and advised approximately 2,600 residents to stop drinking tap water. At the time, Mayor Terje Aunevik expressed concern that "manganese levels have risen explosively." Long-term exposure to manganese can affect the nervous system, particularly in infants and children.

Authorities have since supplied residents with water purified at a local brewery and delivered to a central tank. Manganese levels have since fallen, but early in 2026, sulfate and nickel levels were also found to have exceeded recommended limits, so the ban on drinking tap water remains in effect.

Authorities are considering options such as installing filtration systems at the existing water source or setting up emergency desalination equipment. However, the enormous cost and extreme conditions, including subzero water temperatures, are seen as obstacles.

Mayor Aunevik said, "In Norway, where people have always taken it for granted that they can drink tap water at any time, it is difficult to accept the reality of having to transport water ourselves." He stressed that other small communities should also prepare for similar situations.
