600,000 people are expected to be affected by the potential contamination.
On Tuesday night, Irish Water issued a notice stating that some contaminated water had entered the system at their Leixlip plant.
This resulted in the water being compromised and potentially dangerous, with up to 600,000 people being potentially affected.
The areas affected include parts of Dublin, Kildare, Meath and others, which you can find

Speaking on Morning Ireland on Wednesday, Yvonne Harris, Customer Strategy Manager with Irish Water, shed some light on the situation, saying that the problem was caused by "a small mechanical failure" within the plant and that it was corrected within a number of hours.
Harris said that the notice will remain in place for a day or so and that an update will be released when more information is available.
She went on to say that anyone with any doubts regarding the sanitation of their water supply should err on the side of caution, saying: "If it appears from our website, and from the maps you might have seen on social media, that you're affected - please boil your water. Err on the side of caution."
She also "sincerely apologised" for the incident, and said that it is "most inconvenient" and "far from ideal", while also thanking people who shared the news on social media.
