Why Test for Legionella?
Legionella testing is increasingly recognized as an important part of a water management program for both potable and non-potable water systems. New York, ASHRAE, and Centers for Medicare & Medicaid Services mandate or recommend testing to validate the water management program and to monitor its effectiveness.
