Temporary Treatment Change in Water Treatment Plants Serving Central and Northern Parts of the State

New Jersey American Water will temporarily change its water treatment process from using chloramine to using free chlorine residual at its Raritan-Millstone and Canal Road Water Treatment plants, starting the week of February 20, 2023, and continuing until the end of April 2023. The change is part of the company's annual maintenance program for its water distribution system and is meant to provide customers with safe and high-quality water.

According to Laura Norkute, Director of Water Quality and Environmental Compliance at New Jersey American Water, the temporary change in disinfectant is a standard water treatment practice and a measure of disinfection in the company's distribution system. During the maintenance period, some customers may notice a slight taste and smell of chlorine in their water, which is normal and will only be temporary. Customers who wish to reduce the taste of chlorine can place water in an uncovered glass container in the refrigerator overnight to dissipate the chlorine faster.

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 Laura Norkute, Director of Water Quality and Environmental Compliance, New Jersey American Water. “We perform this distribution system maintenance program every year as an added measure of disinfection in our distribution system.”

The temporary treatment change affects New Jersey American Water customers in various communities across Essex, Hunterdon, Mercer, Middlesex, Morris, Somerset, and Union counties, including cities like Trenton, Princeton, and Elizabeth, and towns like Maplewood, Millburn, and Cranford. New Jersey American Water will continue to monitor the water quality in its system to ensure that it meets or exceeds federal and state drinking water standards.
