Scientists studying levels of arsenic in the country’s groundwater have traced higher levels to areas rich in sandstone, in a study led by NUI Galway.

Arsenic levels breached World Health Organisation (WHO) limits of 10 parts per billion (ppb) in areas of Co Kerry, which was selected as a sample county.
