On April 19, New Jersey American Water will resume using chloramines in water treatment at its Raritan-Millstone and Canal Road Water Treatment plants. These plants serve New Jersey American Water customers in the following counties: Essex, Hunterdon, Mercer, Middlesex, Morris, Somerset and Union.

In mid-January, as part of an annual routine maintenance program for its water distribution system, New Jersey American Water temporarily changed the water treatment process from a chloramine residual (a combined residual) to a 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 the 1980s.

The treatment change applies to New Jersey American Water customers in the following communities: (Communities with an asterisk purchase water from New Jersey American Water.)

The three-month changeover to free chlorine residual enabled the company to perform routine annual maintenance. 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.
