Two weeks of sampling on the Lough Talt Water Supply Scheme is starting today.
It’s part of an action plan agreed between Irish Water and the HSE following the issuing of a Boil Water Notice on Monday.
That was after the parasite crystosporidium was found in treated water coming from the Lough Talt plant.
More than 13,000 people are affected by the Boil Notice which was put in place on Monday.
They are in Tubbercurry and Ballymote, as well as a large surrounding rural area that includes Annagh, Aclare, Bellaghy, Bunninadden, Curry, Lavagh, Ballinacarrow, Carroeeden, kilmactigue, Quarryfield and Coolaney.
The notice also includes customers supplied by the Ogham Group Water Scheme, as well as areas such as Cloontia, Doocastle and the Moylough Group scheme.
Following a two-weeks of testing and sampling, the results will be reviewed before further action is advised by the HSE.
Irish Water also says that it will be increasing its routine scouring on the Lough Talt scheme over the next few days.
This may cause discolouration of the water.
Irish Water points out that people must continue to boil the water until further notice.
Seamus Granahan, Regional Asset Operations Manager with Irish Water has been speaking to Claire Mulcahy. He says sampling has started today:
