The Boil Water notice in south Sligo has been extended until further notice.
The boil water notice has not been in place for over six months, and it will be in place until at least mid September.
Irish Water have confirmed this afternoon that the HSE are continuing to investigate the cause of a number of cases of cryptosporidiosis in the Lough Talt water supply in South Sligo.
The HSE have indicated that the criteria for lifting this notice are zero detections of cryptosporidium,
together with a coinciding period of no reported illnesses in the community.
The next review of the boil water notice is now scheduled for mid-September.
Areas affected by the Boil Water Notice include the towns of Tubbercurry and Ballymote and a large rural hinterland including a number of South Sligo villages.
This boil notice also includes customers supplied by the Ogham Group Water Scheme (GWS) in Co Sligo and a number of areas in Co Mayo.
Irish Water is reminding people in the south and west of the county to continue to boil their water.
