Water Treatment to Revert to Chloramine Use in Central and Northern NJ

New Jersey American Water Announces Conclusion of Temporary Chlorine Treatment Phase

New Jersey American Water customers in parts of central and northern New Jersey are informed that the temporary shift to a free chlorine residual water treatment process will conclude in the week of April 15. 

The utility will resume the use of chloramines, a method in practice since the 1970s, for water disinfection at its Raritan-Millstone and Canal Road Water Treatment plants. This change marks the end of the utility's annual routine maintenance program initiated in mid-February for its water distribution system.

Affected Communities:

The transition back to chloramines affects customers in specific communities across several counties, including Essex, Hunterdon, Mercer, Middlesex, Morris, Somerset, and Union. Notable areas impacted include Irvington, Flemington Borough, Princeton, Edison Township, Chatham Township, and the City of Rahway, among others. This list encompasses a mix of direct service communities and those purchasing water from New Jersey American Water.

About the Treatment Change:

Chloramines, a compound of chlorine and ammonia, are utilized for their effective disinfection properties, meeting all Environmental Protection Agency (EPA) and New Jersey Department of Environmental Protection (NJDEP) drinking water standards. The temporary switch to free chlorine, which some customers may have recognized by a slight chlorine taste or odor, was part of the utility's proactive maintenance to ensure the continued safety and reliability of the water supply.

Transition Details:

As New Jersey American Water transitions back to its standard chloramine treatment process, customers can expect the chlorine taste and odor to diminish. This adjustment is part of the utility's commitment to providing high-quality drinking water and maintaining compliance with regulatory standards.

Customers seeking further details on the use of chloramine in water treatment or with specific inquiries about their water quality are encouraged to visit New Jersey American Water's website.
