A boil water notice has been issued today for Ballycastle Public Water Supply.
The HSE, Mayo county council and Irish Water issued the alert for the area supplied by the Ballycastle public water supply and the Corrower/ Sea Road Group water scheme and Lisbrin Group water scheme to protect consumers following a recent drinking water quality test.
Cryptosporidium was detected in the supply.
Consumers are advised to boil water before consumption until further notice.
Irish Water say they are monitoring the supply and will lift the notice as soon as it is safe to do so.
