A No Swim notice remains in place in the Bettystown area. Warning notices were erected yesterday when the results of tests taken on Monday became available.
A posting on the council website warned that swimming in the water may cause illness and that bathing is prohibited.
The council says preliminary test results on samples taken from the beach on Monday showed elevated bacterial levels.
The water was re-sampled yesterday and the results are awaited.
The cause of the elevated results is under investigation.
NO SWIM notices for the beach in Bettystown have been placed at strategic locations along Bettystown beach.
All updates will be posted on the Council’s website and twitter account and on EPA on-line bathing water quality website ( http://www.bathingwater.ie/" href="http://www.bathingwater.ie/">www.bathingwater.ie ).
The Prohibition will remain in place until results from sampling confirm bathing water quality has returned to satisfactory standard.
Cllr SharonTolan said the council had reacted more quickly in this instance than they had when similar problems arose last June and clear signage went up quickly.
