New figures show there are more than 560,000 people across Ireland drinking water from treatment plants where water contamination is possible.
The Environmental Protection Agency recently added eleven treatment plants to its remedial action list last week - which means there are people whose water supplies are at risk of contamination.
Although Irish Water had worked to bring this number south of 375,000 by the end of 2021 there are now 57 additional plants are now on the list.
