Test results on water in the Clontarf suburb of Dublin are now fully compliant with drinking water standards with the exception of one area, the local authority said today.
Over a thousand residents were warned not to drink water from their taps up to yesterday due to the detection of high levels of bacteria.
In a statement, Dublin City Council said all tests results today were “fully compliant” with the exception of Castle Avenue.
“Work is ongoing at Castle Avenue to identify the source of the problem and restrictions will remain in place pending review of these investigations,” the council said.
It said it recognised the inconvenience that the restrictions had caused and apologised to those affected.
“We are already very appreciative of the residents’ forbearance and for their courtesy and support for our tanker crews and water service staff as they work to resolve the problem.”
The issue arose last Thursday when routine testing by the central laboratory indicated high levels of bacteria in 16 houses in the area. Further sampling following work to correct the problem in these houses indicated that the contamination might have spread to 1,400 houses.
Tests on the water have ruled out E.coli or metals such as lead, and there have been no reports of ill health as a result of drinking the water.
