Järvisydän ensures the water quality of its spa with new Finnish technology – LIQUM 6th Sense monitors water in real time, 24/7

Järvisydän has implemented an advanced, AI-powered water quality monitoring technology at its spa — the Finnish innovation LIQUM 6th Sense service.

With this new system, Järvisydän can monitor water quality in real time, every moment of the day. The 6th Sense technology generates an electrochemical “fingerprint” of the water every minute. Artificial intelligence automatically analyses these fingerprints, performing 1,440 water quality analyses per day, enabling continuous monitoring at a level previously unavailable on the market.


“We also want to ensure, with this new Finnish technology, that the water in Järvisydän’s spa is always clean and safe for our guests,” says Markus Heiskanen, CEO of Järvisydän.

Liqum enables real-time monitoring of water quality, providing a concrete and continuous overview of the spa’s water conditions. “We receive a real-time report on the water and its changes more than 1,400 times a day — it’s like a fingerprint of the water,” Heiskanen explains.

LIQUM’s sensors are also used to monitor the water quality of Lake Saimaa.

“We want to ensure with this new Finnish technology that the water in Järvisydän’s spa is always clean and safe for our customers. At the same time, we aim to set an example of responsible water management and environmental protection,” says Heiskanen.

Järvisydän is also an active advocate for the protection of Lake Saimaa and the Saimaa ringed seal. The same LIQUM 6th Sense technology is used on Järvisydän’s Norppa Cruise vessel, which scans the water quality of Haukivesi between Järvisydän and Linnansaari every day during the open-water season.

The goal is to expand cooperation with Liqum and develop a broader water quality monitoring network for Lake Saimaa over the coming year — one that would eventually cover the entire lake system. The proven systems could, in the future, become part of the new Arctic Cruises network, enabling near-comprehensive monitoring of water quality across Lake Saimaa.

Järvisydän is committed to responsible operations and is continuously developing new, concrete solutions to promote environmental protection. While Lapland has already implemented air quality sensors as part of tourism development, a comparable water quality monitoring system has not previously been utilized within the tourism industry.

Järvisydän will play a central role in the development and advancement of sustainable water management and the protection of Lake Saimaa.

“The wellbeing of Lake Saimaa is crucial for the future of the entire region. New technological solutions help us take tangible actions to protect nature,” Heiskanen explains.

The purity of Saimaa is a shared responsibility

Lake Saimaa is the largest continuous lake district in Europe and one of the most valuable freshwater ecosystems in the world.

“It is the lifeblood of the entire region — a source of clean water, a cradle of biodiversity, and the heart of sustainable tourism,” says Heiskanen. “Saimaa’s clear waters are home to several endangered and unique species, such as the Saimaa ringed seal, the world’s only freshwater seal, as well as the genetically distinct Saimaa salmon and Saimaa char. The future of these species depends on how well we succeed in protecting the water — the very element that sustains both them and us all.”
