Monitoring for the 2021 bathing season commenced on the 24th May 2021 and will continue until mid September 2021.  Sligo County Council will sample the bathing water at Enniscrone, Rosses Point, Streedagh, Dunmoran and Mullaghmore at least every 14 days during the bathing season.

Analysis of the bacterial count in the bathing water will be used to indicate the quality of the water and check that the levels of bacteria in the water are in accordance with the EU Bathing Water Directive parameters and Blue Flag water quality standards.  The parameters tested are E.Coli and Intestinal Enterococci.  The water quality of each sample is assessed as either ‘Excellent’, ‘Good’, ‘Sufficient’ or ‘Poor’.  These limits are qualitative and take account of regulatory limits set out in the Bathing Water Regulations 2008.

The significance of the results is explained in the table below.  In addition, trigger values have been agreed nationally with the HSE and EPA to protect public health.  Bathers will be advised using local beach signage if there is a risk to public health arising from a breach of these trigger values, or bathers can check for the latest updates.

What do the results mean?

Parameter Individual Sample Status





E. Coli  ≤ 250  251 - 500  501 - 1000  > 1000
Intestinal Enterococci  ≤ 100  101 - 200  201 - 250  > 250

Annual Water Quality Rating

The annual water quality rating is determined from results covering the previous four bathing seasons.  This approach averages out the impacts of seasonal variations and takes account of the spread of results.
