Cary, NC – In accordance with state and federal recommendations, the Cary/Apex Water Treatment Facility will temporarily stop adding ammonia to its water treatment disinfection process beginning Sunday, March 1, 2020. Citizens who use water for kidney dialysis machines, fish aquariums or other chlorine sensitive uses should be aware that water may contain chlorine, ammonia, or a mixture of the two at the beginning and end of the process. This month-long, annual process is recommended for municipal water systems and is being conducted in conjunction with other municipalities in the area. The water treatment facility will resume adding ammonia to the water treatment process on Wednesday, April 1, 2020. The Cary/Apex Plant provides treated water to Cary, Apex, Morrisville, the Raleigh-Durham International Airport and the Wake County portion of Research Triangle Park.

To help keep drinking water safe, the Town uses chlorine and ammonia to reduce trihalomethanes, a byproduct formed when water is disinfected with chlorine alone. The State of North Carolina recommends all water systems with the chlorine/ammonia process to cleanse their systems annually by switching to free chlorine and flushing the systems.

“Completing the disinfection process is an integral part of maintaining our utility system and our award-winning water,” said Jamie Revels, Cary’s Utilities Director. “In some cases, water may be slightly discolored, but most residents will notice a minor increase in chlorine odor.” Revels pointed out that any minor changes are temporary and a normal part of the annual process, and citizens with health concerns should contact their healthcare practitioner.

Citizens are encouraged to check their water before washing white clothes. If the water appears discolored, flush house faucets for a few minutes. Citizens who have questions or who have water that fails to clear should dial 311 within Cary, or (919) 469-4000 outside town limits. For more, visit www.townofcary.org/waterchange.
