Homeland Security Research Webinar - Decontamination of Legionella in Home Plumbing Systems and Drinking Water Infrastructure Decontamination at EPA's Water Security Test Bed

Harmful bacteria such as Legionella pneumophila, which causes Legionnaires disease, can live in home plumbing systems when water is stagnant, temperatures are high and the amount of disinfectant (like chlorine) in the water decreases. These conditions help bacteria grow on the pipe walls and form layers of slime called biofilms. L. pneumophila can live in or stick to these biofilms. This webinar will cover the results of research into how to remove, or decontaminate, chemicals and bacteria that stick to the inside of the water pipes that make up home plumbing.
