Three quarters of Ireland's bathing waters are of "Excellent" quality for a third year in a row.
The figures from the EPA also show six beaches failed to meet the minimum mandatory standard and were classified as 'Poor'.
Three were in Galway and three in Dublin.
The three in county Galway that failed to meet the minimum required standard were: Ballyloughane, Clifden and Trá na bhForbacha.
The report says these waters are all vulnerable to pollution events.
Overall the quality of Ireland's bathing waters remains very good with 130 of 140 meeting strict EU standards.
