Columbus Public Utilities officials say foul odors and tastes reported last month were caused by temperature changes that stirred up algae and organic minerals in the water in Hoover Reservoir.
More than 700 complaints have been received from people served by the Hap Cremean Water Plant and Hoover Reservoir. The city has increased water filtration and says the odor should be gone in the next few days. Officials say the water is safe for consumption. At this time last year, residents served by the Dublin Road water plant reported foul odors in the water.
