A temporary 'Do Not Swim' Prohibition Notice was erected at The Velvet Strand Portmarnock for 72 hours last week, just a week after the beach was awarded a Blue Flag.
According to the council, the notice was erected 'due to possible effect on water quality due to the storm water overflow at the pumping station'.
The council explained:'The likely cause was the heavy rain event locally.' Bathing water samples have been taken fortnightly at The Velvet Strand since the summer bathing season commenced and the water had been at an 'excellent' standard in each test.
The Velvet Strand, Portmarnock remained open but beach users were asked to respect the 'Do Not Swim' notice as it was put in place to 'ensure that the health of bathers is not compromised', according to the local authority. The notice has since been lifted.
Members of the public can check for water quality at any of the monitored bathing waters in Ireland in advance by accessing the EPA website at www.beaches.ie or by checking the notice board at the entrance to each beach.
