New Jersey American Water Plans For Temporary Treatment Change in Water Treatment Plants Serving Central and Northern Parts of the State

Release Date: February 02, 2022

As part of an annual maintenance program for its water distribution system, New Jersey American Water will temporarily change the water treatment process from a chloramine (combined) residual to free chlorine residual at the company’s Raritan-Millstone and Canal Road Water Treatment plants. These surface water treatment plants serve New Jersey American Water customers in the following counties: Essex, Hunterdon, Mercer, Middlesex, Morris, Somerset and Union.

“This periodic, scheduled change in disinfectant is a standard water treatment practice that allows us to continue to provide safe, high-quality water for our customers,” said Matthew Csik, Director of Water Quality and Environmental Compliance, New Jersey American Water. “We perform this distribution system maintenance program every year as an added measure to further disinfect the pipelines in our distribution system.”

The temporary treatment process will begin the week of February 7, 2022 and continue until the end of April 2022. During this period, some customers may notice a slight taste and smell of chlorine in their water. This is normal and will only be temporary until the system maintenance is complete. Customers who wish to reduce the taste of chlorine can place water in an uncovered glass container in the refrigerator overnight to dissipate chlorine faster.

“We will continue to monitor water quality in the system to continue to provide service that meets or is better than federal and state drinking water standards,” Csik said.

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

New Jersey American Water has used chloramines in its water treatment process since the 1970s. For more information, visit newjerseyamwater.com

In addition, due to ongoing water treatment plant upgrades at the Raritan-Millstone Water Treatment Plant, New Jersey American Water has temporarily shut down the fluoridation system. The company anticipates that fluoridation will resume by the end of this year. Fluoride is considered a drinking water additive and the temporary absence will have no impact to the quality of your water.
