Details of Bathing Water status at Fingal's beaches for each of the past 4 years.

Bathing waters are monitored, assessed and managed under the requirements of the 2008 Bathing Water Quality Regulations. Bathing waters are sampled every two weeks from the end of May to mid-September to assess the microbiological quality of the water and to minimise any public health risk. Samples are tested for two types of faecal bacteria Escherichia coli (also known as E. coli) and Intestinal Enterococci.

E.coli (Escherichia coli) and Intestinal Enterococci, occur in very large numbers in the gut of warm blooded animal and human faeces. E.coli and Intestinal Enterococci are analysed in assessing bathing waters compliance and are used as “indicator” organisms where their presence in large numbers in bathing waters is a warning of a possible health risk from other harmful bacteria and viruses which might be present.

The annual water quality of bathing waters are assessed and classified as 'Excellent', 'Good', 'Sufficient' or 'Poor'. In the case of Excellent water quality the risk of contracting gastro-intestinal illness is predicted to be ca. 3%, in Good waters ca. 5%, in Sufficient waters 8-9% and in Poor waters ca. >10%.

The annual water quality status is determined from results covering a four year period rather than just the past season’s results using statistical methods rather than simple percentage compliance. This approach is more robust, as it averages out the impacts of seasonal variations and takes account of the spread of results.

Annual Bathing Water Classifications include:

* * * Excellent
* * Good
* Sufficient
- Poor

Classification*E.coliIntestinal Enterococci
Excellent<250<100
Good250-500100–200
Sufficient500-1000200-250
Poor Water>1000>250

* The quality assessment is determined by the poorest of the two microbial indicators e.g. E.coli 400, Intestinal Enterococci 20 would result in a ‘Good’ outcome – the poorer of the two being the E.coli
