Legionella have a ubiquitous occurrence in diverse water environments including water systems where their presence could be an issue because human infections may be acquired through inhalation of contaminated droplets. Drinking water and reclaimed water distribution systems have been shown to be reservoirs for Legionella.
This webcast will present results from a WateReuse Research Foundation project (12-05) designed to assess the occurrence of Legionella following conventional and advanced treatment processes, understand the impact of commonly used disinfectants on the viability of Legionella and associated amoebae in matrices of varying water quality, and utilize advanced methodologies to characterize the Legionella species and serogroups detected.
The presentation will give an overview of the Legionella organisms, occurrence in water, factors contributing to growth and survival, sensitivity to disinfection, and their relationship to free living amoebae. Factors contributing to increased risk and best management practices will be summarized
