Heavy rains in recent days have led to another wastewater overflow at the Ringsend treatment plant, as well as other pumping stations, that has prompted a new swimming ban at several Dublin Bay beaches.
It marks the second time this month that bathing has been prohibited at Dollymount Strand, Seapoint, Sandycove and the Forty Foot at Sandycove.
Both Dublin City and Dun Laoghaire-Rathdown councils say their bans will remain in place pending test for water quality, the first results of which are due on Thursday — in a week where Met Éireann forecasts higher temperatures.
While the bans do not affect Dun Laoghaire Harbour or other beaches in either council area, organisers of water-based sporting events have been advised to take note, as The Irish Times reports.
Notices will be put up on beaches today, Tuesday 25 June, according to RTÉ News.
Update 4.30pm: Dun Laoghaire-Rathdown County Council says tests on an ‘orange slick’ at Sandycove Beach confirm the presence of Noctiluca scintillans, a form of algae, and not raw sewage.
In a statement, the council said the non-toxic species is “a natural summer phenomenon in response to long day length, high nutrients and warm water” and is “not directly associated with the waste water overflows associated with the temporary bathing prohibition”.
