New Jersey American Water’s Routine Maintenance to End at its Swimming River and Jumping Brook Water Treatment Plants

CAMDEN, N.J. – APRIL 10, 2025 – On the week of April 21, New Jersey American Water will complete its scheduled routine maintenance and resume using chloramines in water treatment at its Swimming River Water Treatment Plant in Colts Neck and its Jumping Brook Water Treatment Plant in Neptune. These plants serve New Jersey American Water customers in portions of Monmouth and Ocean Counties.

In mid-February, as part of an annual routine maintenance program for its water distribution system, New Jersey American Water temporarily shifted the water treatment process from using chloramine to chlorine for about nine weeks. Chloramines have long been an effective method of water disinfection that meets all US Environmental Protection Agency (EPA) and New Jersey Department of Environmental Protection (NJDEP) drinking water standards and have been used by New Jersey American Water since the 1970s.

The treatment change applies to New Jersey American Water customers in the following communities:

Aberdeen, Allenhurst, Asbury Park City, Atlantic Highlands,  Avon, Bay Head, Belmar, Bradley Beach, Colts Neck Township, Deal, Eatontown, Elberon, Fair Haven, Hazlet, Highlands, Holmdel Township, Interlaken, Keansburg, Lake Como, Little Silver, Loch Arbor Village, Long Branch City, Matawan, Middletown Township, Monmouth Beach, Neptune City, Neptune Township (incl. Ocean Grove), Ocean Township, Oceanport, Red Bank, Rumson, Sea Bright, Shrewsbury, Shrewsbury Township, Tinton Falls, Union Beach, Wanamassa, and West Long Branch.

This treatment change also applies to residents living in the following communities that purchase water from New Jersey American Water: Aberdeen Township, Avon, Belmar, Keyport, Lake Como, Matawan, Naval Weapons Station Earle, Keansburg and Point Pleasant Borough.

During the routine maintenance, some customers may have noticed a slight chlorine taste and smell in their water. With the resumption of the chloramine process, the taste and smell of chlorine will subside. For more information about the use of chloramine in water treatment, visit newjerseyamwater.com.
