Notices advising people not to swim at four beaches in north Co Dublin have been withdrawn.
These include Rush North, Skerries South, Velvet Strand Portmarnock and Loughshinny.
Results received today from samples taken on 27 August indicate a return to "excellent" status for all.
The notices advising people not to swim in the beaches have now have been lifted by Fingal County Council.
However the 'do not swim' notice issued earlier this week for Front Strand, Balbriggan has been extended for six days due to a poor water quality result.
Investigations are ongoing and no reportable sewage overflows/blockages were found.
Sampling of the River Bracken and this bathing water will continue and investigation of other sources of contamination are being progressed.
Bathers in north Dublin are encouraged to register for Fingal Alerts at alerts.fingal.ie
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.
