Probably the swimming pool uses salt for conditioning.
I just returned from The Villages visiting family, and their pool uses salt
instead of chlorine. They have a bird cage as per regulations.
I also was informed that a lot of houses have extensive lightning rods
protection on the roofs...I could see the little spikes and grounding system
on the rooftops

The modeling over a metal pool structure would involve interpreting the
effect of the fresh water pool on the antenna ground conditions, and also
the ground effect of the metal structure. The analogy could be made to
modeling a mobile whip over a car structure. This has been done and was
written up some years back in "Communications Quarterly" or "QEX". I
believe by a VE ham who worked for Canada's Propagation Laboratory. A
segmented outline of the car shape was used in the calculation of fields,
much as you use segments of the antenna in NEC Antenna modeling.
