A boil-water notice remains in place for the vast majority of homes in Westport, Co Mayo, three weeks after an outbreak of cryptosporidium compromised the public supply.
Irish Water has announced that certain areas in the town are no longer subject to the notice, after an alternative supply from Lough Mask was provided to the town centre.
While this eases the situation for many businesses, a swathe of residential areas south of the rail line through the town are still affected by the notice.
The boil notice was issued on 6 May, following an increase in the number of people presenting with symptoms of cryptosporidiosis.
In a statement this afternoon, Irish Water said the notice remained in place for those areas served by the Westport public supply.
Those affected by the notice are being told to boil tap water if they intend to drink it, prepare food, brush teeth, make ice or prepare infant feeds.
