Swimming should still be avoided at Kellokoski beach
The enterococcus concentration in the swimming water at Kellokoski beach continues to exceed the action limit. A new sample will be taken from the swimming water on Tuesday, 8 July 2025, and the results will be announced once they are available.
In the bathing water samples taken by the Central Uusimaa Environment Centre on 26 June 2025, the levels of intestinal enterococci exceeded the action limit at the Kellokoski and Nummisten bathing beaches in Tuusula and Mäntsälä. On Tuesday, 1 July 2025, signs prohibiting swimming were put up at these beaches. Runoff caused by rainfall prior to sampling may have increased the bacterial concentrations in river water. Elevated enterobacter concentrations may also indicate contamination caused by wastewater.
Repeat samples were taken from the beaches on 1 July 2025. The enterococci concentration in the bathing water at Nummisten beach was below the action limit in the repeat sample, meaning that swimming is once again permitted at Nummisten beach. The enterococci concentration at Kellokoski beach still exceeded the action limit of 400 cfu/100 ml. Swimming should still be avoided at Kellokoski beach.
A new sample will be taken from the bathing water on Tuesday, 8 July 2025. The results will be announced once they are available.
