Ongoing elevated bacterial results (E.coli and Enterococci) have been found from seawater sampling at Front Strand, Balbriggan, informs Fingal County Council.
Results received on August 4 continue to show elevated Enterococci results at the bathing water and this has resulted in an extension of the temporary prohibition (Do not swim) notice in place since July 26 last.
Balbriggan Beach remains open but beach users are asked to respect the notice as it has been put in place to ensure that the health of bathers is not compromised.
Initial investigations found no visible signs of pollution or network issues and resamples of the bathing water have been taken during this incident. River monitoring at the River Bracken has been conducted on scheduled bathing water sampling dates since the start of the bathing season (June). This resulted in a section of the river which flows through the town of Balbriggan being identified for focused investigation.
An in-channel river walk was conducted, and a visible sign of pollution found which could be a potential source of the elevated bacteria in the river. It is not clear yet what is the cause (possibly private misconnection of foul water to surface water or a leak from network or blockage) and an investigation is in progress involving Irish Water and Fingal’s Drainage and Water Pollution teams.
