Transitional and coastal water quality reports and maps

An annual water quality indicators report gives a summary of the current status of Ireland’s estuaries and coastal waters. The assessment for each water body is based on data collected over a 5-year period. Find out more about the latest report Water Quality in Ireland 2001-2003.


More detailed information on the status of individual estuaries and coastal waters is available in the EPA’s national water quality overview reports. In addition to information on trophic status, these reports highlight the other main environmental issues that have the potential to impact on the quality of Ireland’s tidal waters environment. Find out more about the most recent report Water Quality in Ireland – Key Indicators of the Aquatic Environment
