New Jersey American Water will resume using chloramines in water treatment at their Swimming River Water Treatment Plant in Colts Neck and Jumping Brook Water Treatment Olant in Neptune beginning April 10.

For over a month now, they've been running their annual maintenance program for its water distribution system.

There's over a dozen Monmouth County towns that have been affected.

In early February, as part of an annual maintenance program for its water distribution system, NJAW temporarily changed the water treatment process from a chloramine (combination) residual to free chlorine residual.

The seven-week changeover to free chlorine residual enabled the company to perform routine maintenance.

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

Aberdeen, Allenhurst, Asbury Park City, 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, Lake Como, Matawan, Naval Weapons Station Earle, Keansburg and Point Pleasant.

During the transition to free chlorine residual, some customers may have noticed a slight chlorine taste and odor in their water.

With the resumption of the chlorination process, the taste and smell of chlorine will subside.
