Advisory Notice issued for Dun Laoghaire Baths 22 - 29 July 2026

An advisory notice has been issued for bathing waters at the Dún Laoghaire Baths following the detection of elevated levels of E. coli.

An investigation into the source of the contamination is ongoing, although it is believed that the incident is likely linked to animal waste. As a precaution, bathers are being advised of the water quality issue while further monitoring and testing are carried out.

To reduce the risk of illness, you should take the following precautions:

• Avoid swallowing or splashing water
• Wash your hands before handling food
• Avoid swimming with an open cut or wound
• Avoid swimming if you are pregnant or have a weakened immune system

Elevated levels of bacteria are usually short-lived, and most bathers are unlikely to experience any illness.

The advisory notice will remain in place until additional test results confirm that water quality has returned to acceptable standards and that the pollution event has ended. 

Further testing is scheduled, and this notice is expected to remain in effect until at least 29 July.
