This article has been updated to include statements from the DEP and Hopewell Township.

A boil water advisory has been issued for parts of Trenton Water Works’ service area, but confusion abounds to which parts exactly.

An advisory issued by the state Department of Environmental Protection says people in downtown Trenton and small portions of Ewing and Hamilton should boil their water.

The boil water notice affects residents along Route 29, between West Upper Ferry Road and the junction of Lamberton Road and Canal Boulevard, according to a statement released by Hopewell Township. The Hopewell statement emphasized there is no known impact to Hopewell Township’s portion of the Trenton Water Works system.

The “small portion” in Hamilton has been confirmed by Hamilton Township officials as the Deutzville neighborhood. Deutzville includes Hamilton Township streets of Henry, Hewitt, Durand, Deutz, Bunting, Gibson, High and Cherry.

All water in the affected areas—including for bathing, showering, drinking and cooking—should be boiled before use.

The boil water advisory will remain in effect for the affected portions of the Trenton Water system until satisfactory laboratory sample results are returned. The statement from Hopewell Township said tests are being taken today, with earliest possible results being available late tomorrow (Tuesday, Jan. 16).

The alert was issued due to a plant shutdown 5 a.m. Jan. 15. Operations ceased because of elevated turbidities and inadequate disinfection of delivered water. Turbidity refers to the cloudiness or haziness of the water.

This is due to the Delaware River is running rapidly with high water levels, overwhelming the system with water, ice and debris.

“The rapid increase in water levels of the Delaware River has caused turbidity issues,” Trenton Mayor Eric Jackson said in a statement. “Some Trenton Water Works customers have experienced issues. We are working with the Department of Environmental Protection and other partners to address this matter. We will provide more information as it becomes available.”

There continues to be confusion regarding where in the Trenton Water Works system the boil advisory applies. Ewing Township, on its website, says the boil water advisory does not include its residents, contradicting the DEP release. DEP spokesman Robert Geist, in an email, said he was working to confirm the agency’s information with Ewing Township.

When contacted at 2 p.m. Jan. 15, a Trenton Water Works employee could not say which parts of TWW service area were affected by the notice.

“Give me 15 minutes,” the employee said.

Trenton Water Works has not yet reached back to clarify.

Lawrence Township—the only other suburban municipality served by Trenton Water Works—has not issued a statement at this time. Trenton Water Works serves parts of Ewing, Hamilton, Lawrence and Hopewell, as well as the City of Trenton.

Any questions should be directed to Trenton Water Works at (609) 433-9700.

This is the latest in a string of incidents involving Trenton Water Works. Earlier this month, the water company reveled tests in 2017 show its water contains haloacetic acid 5 (HAA5) in levels exceeding federal limits. Last summer, TWW revealed it also exceeded federal lead limits in 2017.
