Evaluating Legionella Detection Rates and Occurrence by Distribution System Characteristics in a Community Water System

Project Update

The goals of this project are to examine Legionella occurrence and concentration throughout a public water distribution system and to analyze these by distribution system characteristics and water quality parameters. Although growing evidence from the scientific literature contributes to the understanding of the larger role of community water systems in Legionella transmission, there remains a need for direct results linking Legionella detection results with distribution system infrastructure or water quality parameters within a community water system. Therefore, findings from this work may allow for a more global interpretation, applicable to other surface water systems interested in potential Legionella vulnerabilities.
