More than a week after warning residents not to drink the water, leaders at a luxury building in Newark’s downtown announced there are no elevated levels of lead in the drinking supply, as previously confirmed by the city.

In a letter to tenants on Saturday, management at 1180 Raymond Blvd. said the results of 30 samples showed lead levels were below the federal action level of 15 parts per billion. In 29 samples, lead levels were undetectable; the other sample registered at 0.6 parts per billion.

The building, known as Eleven80, urged its residents to use bottled water to cook and drink on Aug. 30 after independent tests showed elevated lead levels. City officials, who have long assured apartment buildings are not affected by the ongoing lead crisis, rushed to test the water and quickly found the water was fine.

The building is serviced by the Wanaque treatment plant, which has not had any systemic failures with its anti-corrosion treatment that keeps lead from flaking off old pipes.

“The previous test which precipitated our original notice to you last week appears to be anomalous and confined to an isolated piece of plumbing in the basement,” the building’s Sept. 7 letter to residents said. “The piece of plumbing that was sampled should not affect the water in the residential units or elsewhere within the building.”

Building officials said residents could continue their “normal activities" and apologized for the inconvenience.

Residents living in about 14,000 homes in the western side of the city, serviced by the Pequannock water treatment plant, continue using bottled water. City and state officials are sampling hundreds of homes to understand why two filters meant to reduce lead in the water weren’t working as expected.
