REF: Temporary Disinfectant Conversion
from Chloramine to Free Chlorine

The MEN WSC public water system, (PWS) ID 1750015, will temporarily convert the disinfectant used in the distribution system from chloramine to free chlorine. The conversion will begin on 5/18/22 and continue through 6/20/22. During this period, you may experience taste and odor changes associated with this type of temporary disinfectant conversion.

Public water systems are required to properly disinfect their water and maintain an adequate disinfectant residual in the distribution system. Chloramine, free chlorine combined with ammonia, is widely used as a disinfectant because it persists for long periods while also limiting the formation of disinfection by-product contaminants. Prolonged use of chloramine coupled with other factors that can affect water quality, such as high temperatures or stagnation of water, may result in the growth and/or persistence of organic matter within the pipes of the distribution system, which may hinder the ability to maintain an adequate disinfectant residual. A temporary conversion to free chlorine, partnered with flushing activities, helps to rid distribution pipes of this organic matter and improve the quality of your water overall.

MEN WSC has chosen to implement a temporary disinfectant conversion to free chlorine based on the following: Rising water temperature levels have contributed to increased nitrification causing a more rapid decrease in disinfection residuals. The process is similar to adding bleach (chlorine) to kill algae in pools or standing water, but the level of chlorine is maintained below required maximum limits.
