The City's Water Utilities Department will temporarily change how it disinfects the public water supply in June. Next month the department will use only free chlorine. The temporary conversion from chloramines to free chlorine ensures water safety in pipelines. Customers may see more flushing of fire hydrants and may note a slight change in the smell, taste and look of the water. This may include a “chlorine odor” and slight discoloration. Most symptoms should lessen after a couple of weeks; they do not affect the safety of the water. The Water Department will monitor chlorine levels and water-quality standards daily.
