Naples's score of 64 matches the Florida state average, and below the nationwide average of roughly 78/100 across all U.S. states.

For anyone moving to Naples, the local tap water reflects the unique environmental demands of a large Southeast coastal city experiencing dense population growth. Sourced from the region's characteristic limestone aquifer geology, the drinking water is distributed across multiple local systems that maintain a mediocre, middle-of-the-road quality standard. Prospective homebuyers should anticipate that water characteristics may vary depending on which of the city's utility systems serves their property. While functional, the overall average performance suggests that residents in this part of Florida might experience water quality that, while acceptable, has noticeable room for improvement.
