Boil Water Notice
Over half a million people in Dublin and surrounding counties are being told to boil their drinking water.
The order follows issues with the treatment process at a water treatment plant in Leixlip.
The Boil Notice applies to parts of Fingal, areas in Dublin City Council, parts of South Dublin County Council, parts of Kildare and Dunboyne in Meath.
Irish Water says it's working to fix the problem as quickly as possible.
