New Jersey American Water Issues Mandatory Boil Water Advisory for Green Brook, Martinsville, Warren Township, and Watchung

APRIL 20, 2022 – As a result of the loss of water pressure from a water main leak at the intersection of Mountain Blvd. and Mt. Bethel Road in Warren Township, New Jersey American Water has issued a mandatory boil water advisory to customers within the following communities:

  • Green Brook
  • Martinsville
  • Warren Township
  • Watchung

A potential or actual threat to the quality of water being provided to the above areas currently exists. As a precaution, we are implementing a limited Boil Water Advisory until testing of the water supply is deemed satisfactory. New Jersey American Water will provide information as to when the advisory is lifted.

Effective immediately and until further notice, customers within the impacted area, listed above, are instructed to bring tap water to a rolling boil for one minute and allow cooling before using, or they should use bottled water.

Boiled or bottled water should be used for drinking; preparing foods; mixing baby formula, food, juices, or drinks; washing vegetables and fruit; cooking; making ice; brushing teeth; washing dishes until further notice. Boiling kills bacteria and other organisms in the water.

New Jersey American Water also recommends the following steps:

  • Throw away uncooked food or beverages or ice cubes if made with tap water during the day of the advisory.
  • Keep boiled water in the refrigerator for drinking.
  • Do not swallow water while showering or bathing.
  • Do not use home filtering devices in place of boiling or using bottled water, most home water filters will not provide adequate protection from microorganisms.
  • Use only water that has been boiled (and cooled) to treat minor injuries.
  • Rinse hand-washed dishes with a diluted bleach solution (one tablespoon of household bleach per gallon of tap water) or clean your dishes in a dishwasher using the hot wash cycle and dry cycle.
  • Upon boiling water for potable use, it is suggested that 2-3 gallons of boiled (and cooled) water be stored in the refrigerator in one-gallon containers for use in cooking, drinking, etc. Water can be stored in this manner for 2-3 days.
  • Pets should be provided with drinking water that has been boiled (and cooled) in the manner indicated above.

Impacted customers are being notified of this boil water advisory via the company’s emergency notification system.

New Jersey American Water is working to resolve the issue as quickly and safely as possible. Please continue to boil your water or use bottled water until the company issues follow-up communication when the advisory is lifted. Updates are also available on the website at, under Alerts. If customers have any questions, they should contact 1-800-272-1325.


UPDATE: From New Jersey American Water

The Mandatory Boil Water Advisory issued for the Green Brook, Martinsville, Warren Township, and Watchung service area has been lifted. Normal water use may now be resumed.
