Monitoring of drinking water supplies in the Dublin area is carried out by the relevant sanitary authorities in accordance with the requirements of the European Communities (Quality of Water Intended for Human Consumption) Regulations, 1988. A full analysis of drinking water quality monitoring results, including those for the Dublin area, is contained in annual national reports on the quality of drinking water in Ireland, copies of which are in the Oireachtas Library. Proposals to upgrade the water treatment plants in Dublin are at various stages of planning.
