The public has been advised not to swim at Seapoint beach in south Co Dublin due to elevated levels of E.coli in the water there.
In an advisory notice for Seapoint issued on Friday, Dún Laoghaire-Rathdown County Council advised bathers against swimming there for the next five days.
All five bathing areas in the local authority’s jurisdiction had water samples taken earlier this week.
The results of this sampling effort showed elevated bacteria levels at Seapoint, and, following HSE advice, the council consequently erected the advisory notice advising not to swim at the beach.
Further testing is due to take place in this regard and the results will be available on the council's website and on beaches.ie.
The continuing problems with water quality in Dublin Bay – notably at locations in north Co Dublin; near Irish Water's wastewater treatment works at Ringsend, and in Seapoint – have led users of the amenity to call for year-round water testing.
