Dr. Tom Ryan:

-----is very inconvenient for people, but it is a layer of necessary protection. The increase we are seeing means that incidents are being responded to, boil water notices are being issued in consultation with the HSE and people are being protected. We are not there yet, however; there is a way to go. We continually detect issues of that nature, albeit not as big as in Ballymore Eustace or in Leixlip in 2019. There are ongoing issues. We know that there is a transition from one delivery model to another. That is a matter for the Department and Irish Water. A great deal has been learned from those incidents and we are seeing it come through.

The increases and the reversals are very disappointing. We have a report coming out at the end of this week which looks at 2021. The picture at the end of 2021 was on a very positive trajectory, but we have seen those gains eroded because of five additional plants going on to the remedial action list for various reasons.

Dr. Minihan can add more detail on this point.
