What can be a consequence of inadequate pool maintenance?

Inadequate pool maintenance can lead to significant health risks and reduced patron safety, which is why this is the correct answer. Regular maintenance, including monitoring water chemistry, filtration, and cleanliness, is crucial for preventing issues such as the growth of harmful bacteria and algae. These organisms can cause skin infections, respiratory issues, and other illnesses that pose risks to swimmers.

Additionally, neglecting routine maintenance can lead to unsafe swimming conditions, such as slippery surfaces or poor water clarity, which can increase the likelihood of accidents. Addressing these maintenance needs is vital for ensuring that patrons feel safe and comfortable while using the facility.

Choosing the other options would misrepresent the consequences of poor maintenance. Increased patron satisfaction and an improved facility reputation typically stem from proper maintenance and care; thus, inadequate maintenance would have the opposite effect. Similarly, neglecting maintenance would likely lead to a shorter lifespan of pool liners and other equipment due to increased wear and tear from unaddressed issues.
