Bathing Water API

This is the Bathing Water Open Data API which has three API datasets: Locations, Measurements and Alerts.

Bathing water quality is monitored and assessed to make sure it is safe for swimming during the summer bathing season. Bathing water quality is monitored during the summer bathing season which is between 1 June and 15 September (some local authorities also voluntarily monitor outside of the summer bathing season).

This information is populated using the EPA’s CRM Bathing Water information service and the EPA’s central water quality database Aquarius. Local authorities report this information to the EPA via the Bathing Water Information System (BWIS) and Monitoring Data System (MDS) applications on EDEN (Environmental Data Exchange Network). The EPA provides this information to the public via the responsive beaches.ie website.
