Legionella is part of the normal ecology of public water systems and frequently detected in regulatory-compliant drinking water. Despite the consensus that preventing the proliferation of Legionella is the responsibility of building owners and operators, water utilities may be implicated in Legionnaires’ disease outbreaks. Water utility owners are increasingly expected to have a working knowledge of Legionella within their distribution systems. A WRF Tailored Collaboration Program project, Evaluating Legionella Detection Rates and Occurrence by Distribution System Characteristics in a Community Water System (4983), was conducted with Passaic Valley Water Commission to implement a Legionella monitoring protocol. The project determined the occurrence of Legionella throughout the system and evaluated correlations with Legionella detection by gradient characteristics as well as with a variety of water quality parameters. This webcast discussed findings and lessons learned to provide recommendations for public water utilities interested in monitoring for Legionella.
