What these findings mean

Health authorities word their findings differently, so we group them by what they mean for the people using the facility. Higher-risk findings are the ones that could directly cause illness or injury, such as water that is not properly treated.

  • Pool and spa water qualityHigher risk

    For pools, spas and splash pads, inspectors test disinfectant levels, pH and water clarity, and check safety equipment. Water that is not properly treated can spread skin, ear and stomach infections.

    Recorded 5 times across 4 separate inspections, most recently on June 11, 2026. For example: pH is within required range

  • Chemicals and toxic substancesHigher risk

    Pool chemicals such as chlorine and acid must be labelled, stored apart from each other and handled safely. Mixing them by mistake can release toxic gas, so storage and handling problems are treated seriously.

    Recorded 3 times across 2 separate inspections, most recently on June 18, 2025. For example: Chemical feeder is provided to administer chlorine, chlorine compound or a bromine compound

  • Permits, records and postingLower risk

    Operating permits, water-test logs, posted bather rules and emergency procedures. Daily test logs are how operators show the water was checked and treated between inspections.

    Recorded 4 times across 3 separate inspections, most recently on March 10, 2026. For example: Other tests and records completed and signed

  • Other findingsLower risk

    Findings that do not fit the categories above, such as follow-ups that confirm an earlier violation was corrected, or requirements specific to this type of facility.

    Recorded 12 times across 4 separate inspections, most recently on September 17, 2025. For example: Water heater equipped with an operational tamper-proof upper limit cut-off switch
