The latest report from the Environmental Protection Agency shows the quality of drinking water in public supplies across the country remains high.
The EPA Drinking Water Report for 2017 shows a high level of compliance with microbiological and chemical standards, indicating that most of our water supplies are safe to drink.
However, there are currently 72 "at risk" supplies on the EPA Remedial Action List.
It's expected drinking water in Ireland will be in line with EU standards by 2010 - 16 years after the deadline for compliance.
The number of public water supplies on the Remedial Action List has fallen from 339 ten years ago to 72 at present.
Irish Water says upgrading works on 38 of these supplies will be finished by the end of the year.
There are no public water supplies in Co Mayo currently on the Remedial Action List, however, there are two in both counties Roscommon and Galway - both of which are due for completion by the end of this year.
9 water supplies across the country are currently on a boil water notice - including the Lough Talt scheme will supplies water to over 12,000 people mainly in Co Sligo.
A planning application has been submitted for a new plant to tackle water quality on the Lough Talt scheme, but the EPA says that due to planning difficulties, there is no timeframe available yet for the completion of these works.
