Intro Text 

Dún Laoghaire-Rathdown County Council regularly monitors the water quality along the coast. Following receipt of the results from the samples taken on Monday the 28th September 2015, the Council have taken the precautionary steps of placing a temporary prohibition notice advising against swimming at Killiney Beach, White Rock and Seapoint. The results showed a high level of Ecoli and Enterococci.

  • Enterococci are widely distributed in the environment and are normal commensals of the intestinal tracts of animals, birds and humans. Its presence is indicative of faecal contamination.
  • E. Coli (Escherichia coli) is a faecal coliform and indicator organism because it occurs in the intestinal flora of both animals and humans. Contamination allows the organism to spread to water environments where its presence indicates faecal contamination.


The cause of these high levels are not known and an investigation has commenced. The water at these locations have been resampled and the results are expected back on Wednesday the 7th October 2015. If the resample results are acceptable, the temporary prohibition notice will be removed.
