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.
