My read of that study, which has a fair few bits of extrapolation to my mind, is yes, you are in the "moderate to severe" regions. However, given the indoor issues that you are experiencing, I would have expected far more issues outdoors, e.g. door handles, window trim, down spouts, outside AC condensers, etc. if salt spray/chloride in the air were the prime cause, especially given your home's exposure to hurricanes and hurricane force winds.That is in line with my feelings on the matter too. I think it there is a combination of things going on. Some salt in the air, everywhere, and some chlorides from the well water inside the house.
I have attached a study of atmospheric corrosion which shows that, depending on how you represent the data, my area can be said to be somewhere barely affected and severely affected. And it seems that the air can be corrosive far far inland. Like as in the whole state of the Florida has a corrosive atmosphere according to some of the representations.
So, I am back on the page of not understanding the magnitude of the indoor issues. It is just off the charts in my experience, and I lived in a location with indoor water with lots of chloride. What is the typical winter and summer relative humidity in your house?
All the best,
