A boil water notice, which has been in place for Ballymacarbry for more than a month, has now been lifted.
The notice was issued on the 13th of May because works to drill a new trail well had resulted in the water becoming very cloudy.
The new well was being bored to address water shortages that the area had experienced over previous summers.
Irish Water have now told WLR News that following the receipt of satisfactory monitoring results, the 671 customers on the supply no longer need to boil their water.
Their statement says, "This decision follows consultation undertaken with the Health Service Executive.
"Irish Water operations and compliance experts worked with colleagues in Waterford City & County Council to carry out the necessary works to enable the notice to be lifted as quickly as possible. All consumers on the Ballymacarbry Public Water Supply can now resume normal use of the water supply for drinking, food preparation and brushing teeth.
"Irish Water and the Waterford City & County Council - Health Service Executive, Water Local Liaison Group will continue to meet and review ongoing process control, monitoring and testing of the drinking water supply.
"The Irish Water Customer Contact Centre (1800 278 278) is available to answer customer queries in relation to the lifting of this notice. Further information is available on our website at www.water.ie."
