Fairview Shores is a settled suburb on the north side of Orlando, set near Lake Fairview in Orange County, and it is served largely by municipal water. Most homes here are not on a private well.
Where the wells are is on the older and lakefront lots that kept a private well, and on homes that run a separate irrigation well to keep a lawn green. Those wells draw the Floridan Aquifer, commonly 100 to 400 feet down, through Central Florida limestone that leaves hardness and mineral scale inside pumps, tanks, and check valves over time.
