#Pollution - RTÉ News reports on a new outbreak of cryptosporidiosis in Roscommon's water supply - the third such incident this year.

Five months ago Afloat.ie reported on the last outbreak of the water-borne parasite cryptosporidium, which saw at least 13 people treated for stomach complaints.

Three dead calves found in a stream that flows into one of Roscommon town's main water sources were alleged as the source of that previous surge of the disease-causing micro-organism.

The latest incident affects the Killegian Water Supply Scheme in the south of Co Roscommon near Athlone, and a 'boil water' notice has again been issued for the county.

#Pollution - Three dead calves found in a stream that flows into one of Roscommon town's main water sources have been alleged as the source of two outbreaks of the parasitic disease cryptosporidiosis that have seen 13 people treated for stomach-related complaints, as RTÉ News reports.

Council visits to farms in the catchment area of Roscommon's central water supply scheme have since identified 11 cases of poor management of run-off out of 66 occasions.

Residents in Roscommon and Boyle are still being asked to boil all tap water at home until further notice, and have been warned that home filters will not make the water potable.
