How often is splash pad water tested?

Testing frequency depends on the system and the state. In states like Texas, Florida, Ohio, and Minnesota that regulate splash pads as 'aquatic venues,' operators must log free chlorine, combined chlorine, pH, and temperature every 2-4 hours during operating hours. A full bacterial sample (heterotrophic plate count, E. coli, sometimes Pseudomonas) goes to a certified lab weekly or biweekly. Cryptosporidium spot checks happen after any reported diarrheal incident. Flow-through pads using municipal potable water test less often because the supply is already disinfected. Health inspectors review the logbook during monthly or quarterly visits, and a failed test can shut down operations until follow-up samples come back clean. The full inspection report is usually a public record you can request.
