MARQUETTE — Northern Michigan University is closing three campus buildings as a precautionary measure to facilitate additional water testing after inconsistent lead level readings from limited test areas in each facility, an NMU press release states.

The PEIF, Thomas Fine Arts and the Learning Resources Center will remain closed until NMU receives expedited independent laboratory results — potentially over the weekend — and makes a determination of whether additional investigation and testing is required.

Employees in the three impacted buildings should contact their supervisors about working arrangements for the remainder of this week. Updated information is available at www.nmu.edu/watertest.

The move followed the two-day cautionary closure of the Jacobetti Complex in response to elevated lead readings. Later tests confirmed the Jacobetti levels are safe and fall below the EPA action level of 15 parts per billion, the release states.
