Welcome to the EPA mapping online

The EPA have developed a number of free online mapping viewers for public use. They have been developed to enable the citizen to access information on the environment in a spatial context.

The main viewer available is know as ENvision and it enables you to view environmental information interactively on a map.

Information is provided on:

environmental quality -

  • the quality of Ireland's rivers, lakes, estuaries and coastal waters and the assessment of the risk that these might fail to reach WFD standards
  • the quality of bathing waters
  • air quality (via a link to the corresponding pages on the main EPA website)

facilities licensed by the EPA -

  • the locations of facilities with IPPC, waste and waste water treatment licences.

additional datasets - such as

  • land cover information - the Corine Land Cover data series (2006, 2000 and 1996)
  • indicative soil and subsoil datasets provided to the EPA by Teagasc
  • the locations of Water Framework Directive Protected Areas and River Basin Districts, hydrometric stations and river catchments
  • the location of towns, rivers and lake. 

There are also the following map viewers: 

  • Historic Mines map viewer to accompany a joint project with the Geological Survey of Ireland and the Exploration & Mining Division of the Department of Communication, Marine & Natural Resources entitled "Historic Mine Site - Inventory and Risk Characterisation (HMS - IRC)".
  • Splash: a portal to bathing water quality information at 136 bathing waters around Ireland. From here you can check out the latest bathing water quality during the bathing season together with information on blue flag status, weather, lifeguards and tides before you head to the beach.
  • The Pollutant Release and Transfer Register: this website is an emissions register resembling the register that exists in several countries in Europe. The website is an important milestone towards the Irish Government's ratification of the UN Protocol on PRTR.
