CAMDEN, NJ - After ceasing to use the disinfectants as part of its annual maintenance program, New Jersey American Water will, beginning April 22, again begin using chloramines in water treatment at its Raritan-Millstone and Canal Road Water Treatment plants.

The plants serve New Jersey American Water customers in Union, Hunterdon, Mercer, Middlesex, and Somerset 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 (combined) residual to free chlorine residual. According to the United States Environmental Protection Agency, chloramines have been used by water utilities since the 1930s. More than one in five Americans uses drinking water treated with chloramines
