Temporary Disinfectant Conversion

Temporary Disinfectant Conversion

From Chloramine to Free Chlorine


The Lee County Water Supply Corporation public water system, (PWS) ID 1440005, will temporarily convert the disinfectant used in the distribution system from chloramine to free chlorine. The conversion will begin on July 26, 2021 and continue through August 23, 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 impact 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.


Lee County Water Supply Corporation has chosen to implement a temporary disinfectant conversion to free chlorine based on the following: Lee County WSC has been seeing Un- sequestered iron in the Lexington area which has brought to our attention that a preventive maintenance conversion to Free Chlorine from a Chloramine Burn-out may be needed. This is a maintenance dose and will be within all TCEQ guidelines.
