Since 1981, SPL's research team has made seminal contributions to the fields of microbiology and infectious diseases. Dr. Janet Stout and the SPL team was the first to make the link between Legionella in drinking water and disease in hospital water systems. That discovery shifted the focus of research and water treatment from cooling towers to drinking water as the primary source of disease. With more than 30-years' experience, we continue to make major contributions in Legionella detection, clinical and environmental microbiology, epidemiology, and statistical analyses. To date, we evaluated and introduced all major Legionella disinfection technologies used in the field today and continue to explore new technologies.
