Galway Bay fm newsroom - E. coli was found in eight private water supplies in Galway in 2020.
A report by the EPA which examines drinking water quality in private group schemes and small private supplies, found 20 of the 380 private group schemes sampled nationwide were found to have E.coli contamination.
THMs were also found, a by-product of the chlorine disinfection process which are formed where there is an excess of organic matter in the water source.
The report finds two Galway supplies had THM failures in the period.
Noel Byrne, Programme Manager of the EPA’s Office of Environmental Enforcement says there are a number of reasons for contamination.
