Ballymoney water problems still unresolved
Northern Ireland Water has said a quality issue with supply to around 3,000 properties in north Antrim will not be resolved by Friday.
This week people in Ballymoney have been advised that they will need to boil their water before use.
It had been hoped the issue would have been resolved within the next 24 hours.
Northern Ireland Water is expected to issue a further statement on Friday.
The company has been working with the Public Health Agency and Ballymoney Borough Council to solve the problem.
It appears to be linked to recent renovation of water mains in the area.
Customers in Bendooragh, Balnamore, Finvoy as well as the Ballymena Road and Bann Road areas of Ballymoney town have been affected.
Water used for bathing, showering and washing clothes is not a concern.
NI Water has apologised for the inconvenience caused to customers and will continue testing samples until the water quality returns to normal.
It has provided a list of postcodes affected by the problems.
It will then notify customers by card as well as through news and other media outlets.
