BRIDGEWATER, NJ - New Jersey American Water will resume using chloramines in water treatment at its Raritan-Millstone and Canal Road Water Treatment plants May 1.

The plants serve New Jersey American Water customers in Hunterdon, Mercer, Middlesex, Somerset and Union counties.

In mid-February, as part of an annual maintenance program for its water distribution system, New Jersey American Water temporarily changed the water treatment process from a chloramine residual to free chlorine residual. Chloramines have long been an effective method of water disinfection that meet all EPA and NJDEP drinking water standards, and have been used by New Jersey American Water since 1980s.

The three-month changeover to free chlorine residual enabled the company to perform routine maintenance on its chemical feed systems and remove any residual ammonia from the water distribution system.

During the transition to free chlorine residual, some customers may have noticed a slight chlorine taste and odor in their water. With the resumption of the chloramine process, the taste and smell of chlorine will subside.
