• The county's proactive monitoring is working - routine testing identified a localized issue in the North Oakland Health Center and the Resource and Crisis Center, allowing for immediate preventive action.
• Swift remediation is underway with filters being installed, systems being flushed and follow-up testing being scheduled in accordance with public health guidance.
• Safety remains the county's priority: No known cases are linked to the facilities and overall risk remains low.

Pontiac, Mich. - Oakland County is proactively implementing remediation measures at the North Oakland Health Center (NOHC) and the Resource and Crisis Center (RCC) after routine water sampling detected the presence of Legionella bacteria. There are no known cases of Legionnaires' disease associated with either facility and the risk to employees and the public remains low.

The county's Facilities Management Department has begun installing 0.2-micron point-of-use filters on all fixtures and will undertake further remediation measures, like flushing the building water systems. Testing confirmed that the incoming water supply for both facilities is negative for Legionella.

Water samples - six from NOHC and five from RCC - were collected on Jan. 19. Results - two positives in NOHC and two positives in RCC - were reported to the county on Jan. 27. Alongside remediation, Oakland County is directly communicating with employees and visitors at both facilities to ensure transparency and awareness. Legionella is commonly found in the environment, although infections are rare, with only 41 cases in all of Oakland County last year.

Follow-up routine testing will be conducted after initial remediation. Because these results came from routine monitoring - not a disease investigation - the county is following established CDC guidelines for its routine testing program.

Oakland County continues to maintain rigorous preventive practices across all county buildings, including routine system flushing and water temperature monitoring. Routine water sampling at the Oakland County Jail began Jan. 27. Results are expected within approximately two weeks.
