Management of Legionella in Water Systems - Follow-up Event
Channel: National Academies - Earth and Life Studies
Date: 2020-12-11

This ad hoc meeting of the committee will feature expanded discussion of the report’s recommendations related to environmental monitoring. Topics to be discussed include:

- Pros and cons of monitoring for Legionella species vs. Legionella pneumophila
- Making action levels and thresholds more operational and specific to different exposure routes, to different water system types, and to different locations within complex water systems
- What method(s) should be used, and how would the 50,000 CFU/mL threshold be recalculated for molecular methods
- Collaborative national survey of Legionella

Agenda
-Introductory presentation on the Legionella report
-Purposes of environmental monitoring of Legionella
-Refining action levels for Legionella monitoring
-Where to monitor in complex water systems, from distribution systems to buildings
-Audience questions/comments
