PUBLIC NOTICE TO DRINKING WATER CUSTOMERS
Beginning Wednesday, March 1, 2023 Harnett Regional Water will temporarily change its drinking water disinfection from Chloramines (Free Chlorine plus Ammonia) to just Free Chlorine by stopping the addition of ammonia to its water treatment disinfection process. The Water Plant will resume the addition of ammonia to form Chloramines for the water treatment disinfection process on Saturday April 1, 2023.
The County water system began adding ammonia to the water treatment process August of 1993. Using ammonia in the treatment process helps the County reduce the amount of Trihalomethanes and Haloacetic Acids, by-products formed when water is disinfected with chlorine. This return to chlorine only disinfection is not expected to cause any significant increase in Trihalomethanes or Haloacetic Acids. Trihalomethanes and Haloacetic Acids levels are strictly regulated in the drinking water industry, and the County has maintained compliance with all limits on Trihalomethanes and Haloacetic Acids since regulations were put in place.
Some users of water may be affected by the temporary change in the treatment process. Water customers should be aware that residual traces of ammonia and chlorine must be removed from the water prior to its use in fish aquariums and ponds, kidney dialysis and some commercial manufacturing of food and beverage.
The County along with the Town of Angier also conducts flushing of the water distribution system during this period to hasten the change of chloramines to chlorine residual disinfectant. The system flushing may result in some minor discoloration of the water.
If you have any questions about this change in the water treatment contact Town of Angier by phone 919-639-2071.
