New Jersey American Water will temporarily change their water treatment process to perform routine maintenance starting on April 18.
New Jersey American Water says they will resume using chloramines in water treatment at its Raritan-Millstone and Canal Road Water Treatment plants. Parts of Essex, Hunterdon, Mercer, Middlesex, Somerset, Morris, and Union counties will be affected. The changeover is expected to last two months.
The water services company says during the transition to free chlorine residual, some customers may notice a slight chlorine taste and odor in their water. With the resumption of the chloramine process, the taste and smell of chlorine will subside, the water services said.
In mid-February, 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. The water services company says chloramines have long been an effective method of water disinfection that meets 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:
