Taste and Odor Episode

DSC_1980

Des Moines Water Works uses the Raccoon and Des Moines Rivers as water sources.  By using surface water, there can be some seasonal variations that occur.  The treatment process should eliminate the variation in finished water, but sometimes there will be a slight change some customers may notice.  For example, there may be a slight increase in smell or taste, especially during a river’s thaw.  Although the water is safe to drink, DMWW adjusts its water treatment processes to remedy the situation. To help reduce tastes and odors in your drinking water, DMWW will make timely switches between our source waters as needed to insure the highest quality of water possible. In addition, powdered activated carbon is added at the Fleur Drive Treatment Plant. This material absorbs taste- and odor-causing compounds before settling out in the treatment process. The effective use of chlorine also destroys objectionable tastes and odors.

Some people are more sensitive to subtle changes in taste or odors. To help dissipate the taste and odor, try storing water for drinking in a pitcher in the refrigerator. If you are storing drinking water for convenient use, here are a few things to help prevent taste and odor issues.  Store water in a glass container, as plastic can impart taste or odors to the water.  Also make sure the container has a good seal.  Store in the refrigerator as water will have less flavor when chilled.  If the water has sat for a while, it may be flat.  If this is the case, pour it back and forth between containers or shake it to help aerate the water.  This will help to add oxygen to the water and remove the stale, flat flavor.
