Irish Water has confirmed that a Boil Water notice will remain in place on the Lough Talt water supply.
In a statement today, it says that testing and sampling is continuing on the supply.
Irish Water says it’s working with the HSE and Sligo County Council to monitor the Lough Talt Water Supply Scheme.
The bacteria cryptosporidium was detected in the supply earlier this month and a boil water notice was put in place on the 5th of February.
Since then 13,000 customers on the supply have had to boil their water for all basic household tasks and especially for drinking.
Areas affected by the Boil Water Notice include the towns of Tubbercurry and Ballymote and a large rural hinterland including the villages of Annagh, Aclare, Bellaghy, Bunnanaddan, Curry, Lavagh, Ballanacarrow, Carroweden, Kilmacteige, Quarryfield and Coolaney.
The notice also includes customers supplied by the Ogham Group Water Scheme (GWS) in Co Sligo.
Three areas in Co Mayo are also affected: Cloontia, Doocastle, and the Moylough GWS.
