28 Aug EPA Releases Final Guidance on Efficacy Testing of Antimicrobial Pesticides Against Legionella Pneumophila in Cooling Tower Water
The U.S. Environmental Protection Agency (EPA) released the final guidance and a test method to evaluate efficacy claims for antimicrobial products against Legionella pneumophila (L. pneumophila) in cooling tower water. Legionnaires’ disease (LD) is a serious type of pneumonia (lung infection) acquired by breathing in water droplets contaminated with L. pneumophila bacteria.
