Which option should the hospital's WMP team undertake regarding the POE Legionella findings?

The best course of action for the hospital's Water Management Program (WMP) team, following the identification of Legionella in the Point of Entry (POE) testing, is to notify the water provider. This step is essential because Legionella is a pathogen that can cause serious health issues, especially for vulnerable populations such as patients in a hospital setting. By informing the water provider, the WMP team enables appropriate responses that may include investigating the water supply for contamination, executing corrective actions, and implementing measures to safeguard public health. The collaboration between the hospital and the water provider is crucial to mitigate risks of Legionella transmission and ensure safe water quality for patients and staff.

In contrast, ignoring the results poses a significant risk to health and safety, and conducting additional sampling without taking action does not address the immediate health concerns. Merely informing hospital staff without taking broader measures does not provide a solution that extends to the water source itself, leaving the potential threat unaddressed. Thus, notifying the water provider represents a proactive and responsible response to managing the risk of Legionella.
