The Downers Grove Water Division typically receives an increase in taste and odor complaints during the summer months when water temperatures increase. The number to taste and odor complaints have increased dramatically during the last few years.
Most complaints generally are that the water has an earthy, musty smell and taste.
The source of this taste and odor problem is directly related to higher levels of water vegetation. The application rate of PAC is based upon the concentration of water vegetation and the number of taste and odor complaints. Residents are urged to contact the Village with any taste and odor complaints. They are forwarded to the DuPage Water Commission, who then logs them with the Jardine Plant. When there is a rise in complaints, they increase their treatment.
