Legionella prevention and control
Legionella risk starts in the conditions created by the system, not in the laboratory report.
Temperatures, stagnation, storage, recirculation and aerosol-producing outlets must be understood before choosing representative sampling points.

Context first. Testing plan second.
We consider the building type, water use, periods of inactivity, vulnerable users, network layout and available records. Only then do we select sampling points and parameters that answer a specific question.
A result must lead to a decision.
The laboratory report is read together with the sampling location and conditions. If a problem is found, priorities, corrective actions and an effectiveness check are defined.
