Overview

• The CDC identified 60 waterborne disease outbreaks at splash pads between 1997 and 2022, resulting in 10,611 illnesses, 152 hospitalizations, and 99 emergency visits, with no reported fatalities.
• Cryptosporidium, a chlorine-resistant parasite, caused 67% of outbreaks, accounting for 91% of cases and 81% of hospitalizations, primarily affecting young children.
• Splash pads face unique challenges in maintaining adequate chlorine levels due to the aerosolization of water, which reduces disinfectant concentration.
• The CDC recommends enhanced safety practices, including public education, improved facility management, and the adoption of secondary disinfection methods like UV or ozone treatment.
• Parents are urged to prevent sick children from using splash pads, ensure frequent bathroom breaks, and avoid behaviors like sitting on water jets to reduce contamination risks.
