Eleven water schemes in the county have been taken off the Remedial Action List since 2014.
That's according to a report by the Environmental Protection Agency.
The Remedial Action List identifies drinking water supplies that are at risk of failing to consistently supply safe, clean drinking water.
After a number of years of being on the Remedial Action List, the Ballinasloe water supply has now been removed.
It follows a 650-thousand euro investment by Irish Water for upgrade works including a new UV disinfection system, additional filters and an upgraded control system at the water treatment plant.
The utility says 8,500 people in Ballinasloe now have safe, reliable drinking water.
