Islanders on Aran’s Inis Oírr have been informed that a “do not consume” notice for its public water supply has been lifted.
Irish Water had issued the notice after detecting elevated levels of manganese in the public water supply.
About 257 residents were affected by the notice on Inis Oírr, which was also issued for An Spidéal in Co Galway.
Irish Water said on Monday evening that Inis Oírr residents could resume using the public water for drinking, preparing food and brushing teeth.
Irish Water drinking compliance specialist Dr Pat O’Sullivan acknowledged the impact on the island community and said the agency sincerely regretted the inconvenience.
The situation would continue to be reviewed by Irish Water and the local authority/Health Service Executive liaison group, the agency said.
