Drinking Water Quality

Drinking water, is water used for human consumption whether for drinking, use in the preparation of food, making ice, making drinks with water and brushing teeth. Drinking water comes from different sources including groundwater ( e.g. boreholes or springs) and surface water ( e.g. lakes, rivers). All water is treated to make it safe to drink.

Since 1 January 2014, responsibility for public water supplies has transferred from local authorities to Irish Water, the new national water services authority. Local authorities will continue to operate public water supplies on behalf of Irish Water.

Irish Water is responsible for monitoring the quality of the public water. Monaghan County Council on behalf of Irish Water undertakes monitoring of all public supplies in Monaghan. Local authorities are responsible for the monitoring of private regulated water supply in their areas. Currently both public and private regulated water supplies are tested by Monaghan County Council to make sure that the water is safe to drink.

All drinking water must comply with “The European Communities (Drinking Water) Regulations, 2014 (S.I No. 122)” which set standards for 48 individual microbiological, chemical and indicator parameters.

Monaghan County Council carries out regular monitoring of public water supplies and private regulated water supplies in accordance with the Regulations. Monaghan County Council sends all of these monitoring results to Irish Water who in turn submit them to the Environmental Protection Agency. The results are published in the EPA Annual Report on Drinking Water Quality.

Irish Water is responsible for managing and delivering water services to homes and businesses served by Public Water Supplies and Wastewater Agglomerations.
