Chloramine to Temporary Free Chlorine Conversion

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 9/7/2021 and continue through 10/6/2021.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 tempertured or stagnation of water, may result in the growth and/ or persistence of natural 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 activites, 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:

High Nitrification Levels affecting disinfectant residuals.
