The results of the latest water samples from three north Sligo beaches are due around lunchtime today, Thursday, and it is hoped that bathing restrictions can be lifted.
A temporary ban on bathing at Rosses Point, Streedagh and Mullaghmore beaches was put in place on Friday after the level of intestinal enterococci in samples taken on June 20 showed non-compliance with nationally set standards.
The bacteria tested are indicators of faecal contamination, so as a precautionary measure the HSE advised a temporary prohibition on bathing.
Sligo County Council have said that the cause is unknown, however it is thought that the quality of water may have been affected by prolonged rainfall over the last week.
