A luxury tower in the heart of Newark’s downtown does not have elevated lead levels in its tap water, city officials announced Sunday, two days after the building’s management urged tenants to use bottled water.

Mayor Ras Baraka said the city performed additional tests through an independent laboratory that found the tap water contained undetectable levels of lead at 1180 Raymond Blvd. He urged buildings to use state-certified labs for future testing to ensure accuracy.

The building is serviced by the Wanaque treatment plant "where the source water does not contain elevated levels of lead and the corrosion control system is effective at preventing lead from entering the water in buildings with lead service lines,” Baraka said in a statement.

On Friday, the management at Eleven80 sent residents an email warning that new test results from an independent consultant found lead in the water and instructing residents to use bottled water for drinking and cooking.

But city officials did additional sampling on Saturday -- in the presence of building staff -- which showed the water contained less than 5 parts per billion of lead. The federal limit for the contaminant is 15 parts per billion.

Cogswell, which owns the building, did not immediately return a request for comment on Sunday. But in a follow up email to residents on Saturday said city officials were working “feverishly” to evaluate new samples.

“Be advised there is a testing protocol that has to be followed, as mandated by federal regulators,” management wrote. Residents said they had not received any updates from management as of Sunday afternoon.

It’s unclear what company performed the tests for the building that found the elevated lead levels or if they were certified by the state Department of Environmental Protection.

City officials said Saturday’s results were consistent with tests they ran at the building in January, which showed the water was safe.

The confusion comes as the city distributes bottled water to residents with lead services lines -- garden-hose sized pipes that connect underground water mains to homes. Large buildings like Eleven80 do not use lead service lines.

“Large buildings require pipes far larger than lead service lines,” Baraka clarified.

Newark’s lead levels spiked in 2017 when lead from old pipes dissolved into the tap water. That happened because the treatment meant to form a protective crust inside the pipes failed at the Pequannock plant that pumps water to residents in the West and South wards and parts of the North and Central.

Eleven80 is serviced by the Wanaque plant, run by the North Jersey District Water Commission, a coalition of water authorities.

“The Wanaque water system has been thoroughly tested by various entities, and it does not have any trace of elevated lead," spokesman for the commission, Bill Maer, previously said. A federal judge on Friday agreed that residents in the Wanaque area were not at risk and did not order bottled water distribution to these homes.

Newark is rolling out a $132 million program to replace all 18,000 lead service lines across the city in three years and has also changed the treatment at Pequannock which will take months to work.

The filters distributed by the city as a stopgap measure, meanwhile, are under the microscope after two tests found they were not removing lead at expected levels. Those results prompted a mass distribution of bottled water to 14,000 homes.
