A high number of fecal-derived bacteria has been detected in the water at the Kernaalanjärvi beach in Janakkala

A systematic bathing water sample taken from the Kernaalanjärvi beach on July 9, 2026 has detected a quantity of e.coli bacteria exceeding the action limit, meaning that the water may contain disease-causing microbes. Swimming at the Kernaalanjärvi beach should be avoided until a repeat sample result below the action limit is obtained.

There is currently no clear reason why the bacterial concentration has increased.

The repeat sample will be taken on Tuesday, July 14. The results of the repeat sample will be posted on the beach noticeboard once they are complete.
