Splash pad aerosol

Definition

Fine water droplets generated by spray jets that can carry chlorinated water — and, rarely, pathogens — into the air around the pad and into kids' lungs.

Aerosolization is the mechanism by which a few rare splash-pad outbreaks have spread Legionella to nearby visitors. The risk is highest at recirculated pads with chemistry lapses and stagnant tank water. Proper recirculation, UV treatment and routine flushing eliminate aerosol pathogen risk. Outdoor pads have far lower aerosol-illness risk than indoor pads because air dilutes constantly.
