According to a study published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology, the investigators developed a model system that enabled measurement of biofilm formation and growth of legionella. 

They compared a water supply system with a very low concentration of dissolved organic matter with one with a high concentration.

Drinking water from sources with higher concentrations of organic matter induced higher biofilm concentrations that supported legionella growth, according to the study.
