Public Notice
February 28, 2012

For many years, public water systems have added Chloramines to drinking water as a primary or secondary disinfectant. This is because of concerns of formation of disinfection by-product as the result of using free chlorine. The City of Tecumseh is purchasing water from the City of Shawnee which uses Chloramines. Please accept this notice as your 30 days notification (Pursuant to OAC 252:631-3-3(d)(1)), that Chlorine Dioxide/Chloramines disinfectants will be used in the City of Tecumseh water system and that these disinfectants could affect certain activities.

Hemodialysis: A potentially serious problem arises when tap water containing chloramines is used in hemodialysis (artificial kidney machines). Chloramines pass through the dialysis membrane and their toxicity to patients under dialysis conditions is undisputed (Eaton ct al. 1973). Chlorine Dioxide and its by-products may have similar effects. Operators of dialysis centers know that tap water must be treated before use in dialysis.

The Association for the Advancement of Medical Instrumentation has proposed a limit of 0.1mg/L for chloramines in hemodialysis water. It is imperative that dialysis centers and users of home dialysis systems to be aware that chlorine dioxide/chloramines will be used in the City of Tecumseh water system and that treatment is necessary to remove these parameters from hemodialysis water. The types of controls available to users include carbon filtration and reverse osmosis or chemical reduction. Other substances in tap water besides chloramines are also known to interfere with dialysis. These include copper, fluoride, sulfate, nitrate zinc and aluminum.

Fish tanks and fisheries: The toxicity of chloramines to fish is well-known. Most breeders and owners of tropical or other aquarium fish know that tap water should not be used in aquaria without proper treatment and aging. Yet, a number of cases of aquarium fish being killed by chloramines in tap water have been reported, particularly when conversion between disinfection methods has occurred at the treatment plant. Since chloramines are more persistent than free chlorine (which is also toxic to fish), treatment and aging of water to be used in aquaria is more critical when chloramines are present. Suggested action for fish fanciers, breeders, or pet shop owners includes the use of activated carbon filters. Care needs to be taken to replace filter cartridges before breakthrough can occur.
