The EPA has a wide remit and is responsible for a range of tasks relating to the authorisation of activities that could have an impact on the environment or on human health. We carry out monitoring of the quality of our air, our freshwater, groundwater and marine waterbodies and our use of natural resources. Through our research and development programme, we are generating the knowledge and expertise needed to protect and manage Ireland's environment.
This section of our website contains a range of information services to the public on our activities and provides communication and guidance services for our regulated communities.

The Remedial Action list is a record of the public water supplies known to be at risk and where the EPA is requiring Irish Water to take corrective action. The EPA has instructed Irish Water to submit an action programme for the improvement of each of these supplies and has initiated enforcement action where action programmes were not being prepared or were not prepared to the satisfaction of the EPA. This includes issuing legally binding Directions requiring specific work to be carried out.
In Ireland, there are no national end-of-waste criteria for compost and digestate derived from source-separated materials. This study developed a quality standard for digestate and an updated standard for compost, it also recommends a strategy on how Ireland should implement national end-of-waste criteria for compost and digestate. It also examined best practice in other countries and options for having end-of-waste criteria.
