Results from water-quality tests are expected by Friday evening after an overnight water main break and leak under the Great Miami River that left thousands of residents without water or with low water pressure.
The affected line was located just west of the Keowee Street Bridge, a spokesperson for Dayton says.
But a boil advisory remains in effect for parts of Montgomery County.
Approximately 30,000 service connections, or around 75,000 residents, are in areas affected by the boil advisory.
Montgomery County Health Commissioner Jeff Cooper says the boil advisory is a precaution.
"We’re asking all individuals to adhere to it until test results come back confirming that there is no contamination," Cooper says.
County officials also invite residents to call a helpline to find out whether your address falls under the current boil advisory: 937-781-2688.
