MESA, Ariz. — Mesa officials are warning city residents about a slight change in the odor and taste of their water for the next few weeks.
The city’s water resource department says the change is caused by a byproduct of seasonal algae called Geosmin.
Officials say Geosmin isn’t harmful and the water is safe to drink and use in daily activities.
They also say Mesa’s water continues to meet all state and federal drinking water standards.
At low concentrations, Geosmin causes a musty or soil-like odor and taste in the water.
Mesa’s water treatment plant is using carbon treatment to reduce geosmin in the water distribution system.
