Legionella Management and Treatment
January 28 @ 2:00 pm - 3:00 pm
This webinar is part of the Small Systems Monthly Webinar Series from the Environmental Protection Agency (EPA).
Presentation 1— Public Water System Characteristics That May Affect Legionella Occurrence in Building Water Systems (Presented by Ken Rotert, EPA’s OW). This presentation will highlight EPA’s efforts to reduce Legionella risks through regulatory revisions, treatment technologies, and research on premise plumbing. An overview of public health impacts, challenges to addressing Legionella in drinking water, and potential risk factors in municipal supplies will be included.
Presentation 2— Impact of Chlorine and Chloramine on the Detection and Quantification of Legionella pneumophila and Mycobacterium Species (Presented by Maura Donohue, EPA’s ORD). Potable water can be a source of transmission for legionellosis and nontuberculous mycobacteria (NTM) infection and diseases. This presentation will investigate the influence of disinfectant type and total chlorine residual (TClR) on the detection and concentration of the five leading pathogens associated with these infections and diseases.
