Swimmers are being reminded this weekend that a number of beaches in Dublin have bathing water warnings in place.
The areas affected are Dollymount, Sandymount and Merrion Beaches, with members of the public being advised not to swim in those areas.
The advice will remain in place over the weekend, with results of new samples due on Monday.
North Inner City Green Party Councillor Ciarán Cuffe believes the current system is not up to standard.
He argued: "Well I think Irish Water need to have a mechanism in place to have an early warning on possible pump failures. I think they need to have a back-up plan.
"I think it's ridiculous that the failure of one single pump can stop bathing all around Dublin Bay."
Cllr Cuffe added: "I'd say to the general public observe the warnings, and hopefully there'll be updates. With a bit of luck, we'll be back in the water very soon."
The bathing warning comes amid the continuing warm weather in the city, with temperatures of up to 22 degrees being forecast for today.
