DES MOINES, Iowa — Grimes residents may notice that their water tastes and looks a little different starting Monday.

The City of Grimes Water Department and Central Iowa Waterworks are changing the disinfectant used in the public water supply. Instead of chloramine, which is a combination of chlorine and ammonia, the city says free chlorine will be used.

The disinfectant switch begins on Monday and is expected to last two or three days.

Officials say residents may notice a stronger chlorine smell or taste in the water, and a slight discoloration or cloudiness. The differences are temporary, and the water is still safe for drinking, cooking, and bathing.

The city said the change is being made to make the city’s water compatible with the rest of the Central Iowa Waterworks communities to facilitate the combining of resources if needed.
