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 2 times across 2 separate inspections, most recently on February 6, 2026. For example:
Is the bacteriological quality of the water in this pool satisfactory (Non-Critical)?
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 once on January 10, 2024. For example:
Is the chemical quality of the water in this pool satisfactory (Critical)?
Food safety training and certificationLower risk
Many jurisdictions require trained pool operators and certified lifeguards. These findings mean required training, certification or staffing records were missing at the time of inspection.
Recorded once on March 19, 2025. For example:
Does the pool have adequate written policies, plans and posted rules and safety information to ensure that the pool is operating in a safe manner?
