Changes in water quality

The tap water in Longyearbyen currently does not meet water quality standards. The levels of sulfate and nickel exceed recommended limits. People who are sensitive to sulfate or nickel should therefore avoid drinking the tap water.

Manganese levels have decreased and are no longer considered a health concern.

It is still recommended to use free drinking water, which can be picked up in your own container at the Svalbard Store.

Since September 2025, the Longyearbyen Local Council has recommended not drinking tap water. Free drinking water can be collected at the Svalbard Store in your own containers.

This water is supplied from the water treatment plant at the Svalbard Brewery. The water is produced using reverse osmosis and meets all drinking water standards, including odor and taste.

Results from the latest analyses:

• Manganese: Levels in the water distribution system are around 200 µg/l. This is above the limit value, but not at a level that gives cause for concern regarding health effects.
• Sulfate: Levels have increased and are close to 1000 mg/l.
• Nickel: Levels have been measured up to 30 µg/l. The limit value in the regulations is 20 µg/l (World Health Organization, WHO limit value 70 µg/l)

What does this mean in practice?

For healthy individuals, this is unlikely to pose any health risk, but the water may have an unpleasant odor and taste.

People with stomach problems, young children, and the elderly may experience loose stools or diarrhea due to high sulfate levels.

Recommendation for residents

- Avoid drinking tap water if you are sensitive to sulfate or nickel

- Tap water can be used for showering, washing, and other purposes

- Free drinking water is available at the Svalbard Store

Moving forward

The Longyearbyen Local Council will continue to monitor water quality and work on measures to improve the water supply.

The goal is to ensure stable and satisfactory water quality for all customers.
