- What is the current drinking water disinfection method?
The current method of disinfection used by the City of Havelock is Chloramination. Chloramination is the use of both ammonia and chlorine to disinfect water. When added at a carefully controlled level, the ammonia and chlorine react chemically to produce combined chlorine, referred to as chloramines. Chloramines are safe in drinking water and serve as an effective method of disinfection.

Fish owners can get more information from their local pet supply stores; kidney dialysis patients should speak with their healthcare providers if they have concerns.
