#DublinBay - Killiney Beach has had its Blue Flag lowered for the second time in four weeks after tests on Monday 11 August showed high levels of E.Coli and Enterococci in the water.
Dun Laoghaire-Rathdown County Council, which has also posted a no-swimming advisory at Sandycove Harbour for high levels of the latter contaminant, expects to learn the results of its latest water samples this Friday 15 August.
But for the meantime, Killiney's Blue Flag is removed pending the council's investigations into the cause of the high bacteria readings, which is not yet known.
Last month Killiney and White Rock in Dalkey were closed to swimming due to unsafe levels of bacteria in the coastal waters of south Dublin Bay.
It's the latest in a string of bad news for Dublin's beaches, following last week's bathing prohibition at 12 beaches in the north of the county, and the arrival of dangerous stinging sea creatures such as the Portuguese man o'war and the lions mane jellyfish.
