Aqua Ohio Customers: Taste and Odor Alert

February 2, 2026 -- Over the weekend, operators at Aqua’s Marion water treatment plant detected an organic odor caused by geosmin in the water entering the plant. The compound is not considered a health threat but may result in taste and odor issues in tap water. 

Staff continue to operate enhanced water treatment with the addition of carbon to absorb taste and odor causing organic compounds that may exist. Crews have also increased water quality testing and targeted flushing. 

The water meets state and federal requirements and there is no need to boil water. Aqua continues to work with the Ohio EPA to ensure safe water.

For more information customers can visit the disruption map or call Aqua customer service at 877.987.2782.

February 16, 2026 -- Earlier this morning, operators at the Marion water treatment plant again detected taste and odor issues in the water system. They made treatment and source water adjustments and have not been able to detect any issues since 6:00am.

Crews are working to locate any appearances of the compound causing the issue as it moves through the distribution system and are opening hydrants to remove it.

If you noticed a change in water taste or odor today, it is important to contact our customer service department at 877.987.2782. This will allow us to log the appearance and to dispatch staff to respond in that area. Tests have not indicated any regulatory exceedances and there is no need to boil water.
