The Mayor of Galway says he has been contacted by a family who say the level of lead in their water is three times above the safe limit.
Padraig Conneely said he is deeply concerned that the problem with lead contamination may be more widespread in the city.
He said the family, who live in the Taylors Hill area of the city, wish to remain anonymous but have contacted him to say they had their water tested by a public analyst after becoming concerned about recent lead contamination findings in other areas of the city like Old Mervue.
The test result came back with a reading of 79 micrograms, which is three times the permissible level.
He said there is a need for more in-depth testing throughout the entire city and a more rigorous breakdown of the findings.
A spokesperson for Galway City Council said an agreed testing regime was in place following consultation between the council, the Health Service Executive and the Environmental Protection Agency.
In the meantime, the spokesperson said it was wrong to draw conclusions.
Contamination
Meanwhile, a UK consultant will meet engineers from Galway City Council on Friday to advise on best practice in tackling lead contamination.
Director of Services Ciarán Hayes said the council has devised a programme together with the HSE and EPA.
In the short term, work has begun to adjust the pH level of the water to reduce interaction between the water and the lead pipes.
Over the coming months the council intends to work to further reduce chemical interaction until the pipes can be replaced.
It is envisaged that full replacement of the lead pipe distribution network will be carried out over the next two to five years.
The HSE has confirmed that the 35 people living in the Old Mervue area of the city have been given the all clear after tests were carried out to determine the level of lead in their blood.
The tests followed findings of excessive lead levels in a number of houses in that area.
Water testing will continue to sample one to two houses per road in Old Mervue and one in 30 houses in other affected areas including Shantalla, Claddagh and Bohermore.
Water tanks are still in place in Old Mervue and free water supplies are being distributed to the elderly and people with disabilities.
The council is advising that infant formula be prepared with boiled water from the tanks in Old Mervue or suitable bottled water.
