The Boil Water Notice for homes in Ros a Mhíl has been lifted this week after more than five months in place.
Uisce Eireann issued the BWN for some 250 homes supplied by the Rossaveal Reservoir at the end of last October.
It was lifted with immediate effect on Wednesday evening after consultation with the HSE.
All consumers on the Spiddal Public Water Supply served by Rossaveal Reservoir can now resume normal use of the water supply for drinking, food preparation and brushing teeth.
The notice was first issued due to low levels of chlorine and detections of Coliform bacteria in this part of the supply network.
Uisce Éireann Operations Lead, Eoin Hughes said: “Uisce Éireann wishes to thank the people of Rossaveal for their patience, co-operation and assistance during this Boil Water Notice.”
“We are grateful to the media, elected representatives and also members of the public who shared updates.”
