ESSEX COUNTY, NJ — On April 25, 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 Essex, Hunterdon, Mercer, Middlesex, Morris, Somerset and Union counties.
In mid-February, as part of an annual routine maintenance program for its water distribution system, NJAW temporarily changed the water treatment process from a chloramine residual, which is a combined residual, to a free chlorine residual. Chloramines have long been an effective method of water disinfection that meets all Environmental Protection Agency and N.J. Department of Environmental Protection drinking water standards and have been used by NJAW since the 1980s.
The treatment change applies to NJAW customers in the following Essex County communities: Irvington, Maplewood and Millburn.
The two-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.
