There was one finding of pesticides above allowed limits in Tipperary last year, according to to Uisce Éireann.
It happened in the Thurles area but the utility says it wasn’t a risk to human health.
The utility is warning people we need to think carefully before using sprays to protect the public water supplies.
Farmers, gardeners and greenkeepers across Tipperary should think before using pesticides.
Uisce Éireann is posing the question ‘to spray or not to spray’ this summer.
The number of pesticide exceedances in public drinking water supplies has decreased by more than 50% in Ireland since 2017.
However there was a small increase in the number of exceedances detected last year by Uisce Éireann’s public water supply monitoring programme.
Gareth O’Brien is Asset Strategy Technical Lead with Uisce Éireann says there is no risk to public health with any pesticide exceedance.
“In 2024 we detected pesticide exceedances above the drinking water limit on 66 occasions in our water supplies which was a slight increase from 2023.
“But we’d like to just raise awareness with any pesticide users be it farms or gardens with the nice weather or people maintaining sports grounds just to consider the local water supplies because one drop of pesticide that enters a water course can lead to an exceedance up to 30 kilometres away.”
