A SWIMMING BAN has been put in place at Balcarrick beach in Donabate, north Dublin.
Fingal County Council issued the temporary notice after the results of a routine sample showed a deterioration in the water quality.
It’s believed the contamination has been caused by animals and birds.
The HSE has asked people to stay out of the water until further tests show the quality has improved.
Another sample was taken today and sent for testing with the results due on Monday.
The beach is still open to the public but people are being asked to respect the notice.
