City residents could notice a slight chlorine smell in their water for the next three weeks as the city’s water system undergoes a conversion from chloramines to free chlorine disinfection.

The preventive maintenance is intended to maintain the city’s water quality, according to a news release from the city.

The amount of chlorine used during the temporary change will result in between 2.5 and 3 parts per million of water.

Those who are sensitive to chemicals or have concerns should consult with a family physician. Those who use city water for dialysis machines also should consult with their physician.
