The Boil Water Notice enforced on the Whitegate Public Water Supply has been lifted with immediate effect.
The notice has been in place since Christmas Day of last year.
In a statement to RedFM News, Irish Water confirmed that remedial measures have been completed and that they and the HSE are safisified with water test results.
All consumers on the Whitegate Public Water Supply can now resume normal use of the water supply for drinking, food preparation and brushing teeth.
Irish Water and Cork County Council have warned that there is a possibility that the notice may have to be re-issued in the coming weeks or months if the raw water deteriorates again or if there is a bad spell of adverse weather.
Long-term plans for a significant investment in the water infrastructure in the area, which are necessary to end the frequent Boil Water Notices in East Cork over the last number of years, are proceeding.
This includes plans for a new treatment plant and significant upgrades to other treatment plant sites.
