Mr. Des Joyce:

There has been a spike in manganese cases across the country in the last couple of years, whether it is related to sustained dry periods or not. We are carrying out a separate study on that at the moment and the Environmental Protection Agency, EPA, is also working on that. Within Uisce Éireann and also within other countries, an increase in manganese has been seen. We are working hard to figure out what is causing this and to try to be able to predict it and be able to treat it when it happens.
