Businesses and local people in Cahersiveen, Co Kerry have been told to boil their tap water after cryptosporidium was detected in their supply.
The boil water notice, which was issued this afternoon by Irish Water and Kerry County Council, will affect 1,400 customers supplied by the Cahersiveen Public Water Supply.
In a statement, Irish Water acknowledged the impact and inconvenience to local people.
It said the HSE has advised that while tap water is not safe for drinking, people can continue to use it for personal hygiene, bathing, flushing of toilets, and for hand washing in line with Covid-19 advice.
The company said the restoration of a safe drinking water supply is a priority and they are working with Kerry County Council and contractors to restore it as soon as possible.
