Water quality testing log
Definition
A daily handwritten or digital record of chlorine, pH, temperature and turbidity readings — typically kept in a binder at the pump house — required by state pool code to be available for health-department inspection.
Water quality testing logs are the paper trail that proves a splash pad is operated safely. State codes typically require chemistry checks every 2–4 hours during operation, with readings recorded immediately and the log retained for 1–3 years.
Municipal pads have shifted to digital logs (Pentair, Hayward) that auto-record sensor readings every 30 seconds and flag any out-of-range value. The digital log is emailed to the parks director nightly and shared with the health department on request. A missing log is one of the fastest paths to a forced closure.
