What is likely happening
Cooling towers carry both mechanical and public-health risk, including Legionella, so flow, scaling, and water treatment problems should be corrected promptly. Several cities and states require tower registration, water management plans, and regular testing.
What you can safely check
- Check that water treatment is running and logs are current.
- Look for heavy scale, algae, or mist drifting onto nearby areas.
What an inspector will look at
- Water management plan
- Treatment and sampling records
- Mechanical condition
Does this affect compliance?
NYC and some states require registration, inspection, and Legionella sampling for cooling towers.
When it becomes urgent
Urgent if Legionella sampling came back positive.
