Council authorities have reversed a swimming ban at four north Dublin beaches.
The temporary prohibition was issued on Saturday in response to suspected sewage discharge at the Balbriggan, Skerries, Loughshinny and Rush beaches.
Beach users had also been warned to take care entering the sea at three other Fingal beaches hit by pollution following an “overflow” from a sewage plant.
The advisory notice for the Claremont and Sutton beaches, where a range of restrictions had been placed on swimming, have now been lifted.
The notice for Portmarnock will remain in place until at least Monday, when the results of water sample tests will be made available to Fingal County Council.
Sample tests showed water quality at the six other beaches had returned to satisfactory levels, the local authority said.
Clare County Council has also lifted restrictions on bathing introduced at Kilkee beach due to bacterial contamination.
The council said water sampling tests carried out yesterday indicated the water is clean.
