Two more Baltimore City buildings have been found to have elevated levels of Legionella bacteria in the water — Baltimore City Hall and the Abel Wolman Municipal Building.

“Due to the elevated levels of bacteria found, the city is moving forward with cleaning, system maintenance, and other mitigation efforts, including flushing and chlorination, to address the presence of Legionella bacteria in these buildings, beginning this afternoon,” the mayor’s office wrote in a statement Friday.

Despite not yet having test results for the Benton Building, the building will undergo precautionary remediation measures alongside City Hall and the Wolman Building this weekend, the statement explained.

The buildings closed early Friday, it said, to accommodate the mitigation efforts.

The results for the Benton Building are expected on Jan. 5. The city received the test results for City Hall and the Wolman Building Friday, the statement said.

The Baltimore City circuit courthouses and the District Court on East Fayette Street reopened Thursday after being treated for Legionella bacteria earlier this week.

Legionella is the bacteria which can cause Legionnaires’ disease, a severe form of pneumonia. The city recommended the courthouses close last week, although the health department did not require such a measure.

The courthouses were retested for the bacteria after being treated Monday and Tuesday.

No cases of Legionnaires’ disease have been reported in connection to the courthouses or any of the other city buildings where high levels of the bacteria were detected.

Government buildings across Baltimore are under scrutiny for Legionella due to a new proactive testing regime from the state Department of General Services. Since November, a total of six office buildings and five courthouses have tested with high levels of the bacteria. Several of the buildings have since been cleared.
