Actually, it wasn't the well water that exposed it. It was "tap water" from a utility source.

There was a recent survivor.

This was the answer I got from CDC on the parasite in Florida springs.
Naegleria fowleri is a heat-loving microbe. It grows best at higher temperatures up to 115ºF (46ºC) and can survive for short periods at higher temperatures. It is less likely to be found in the water as temperatures decline in such temps that you see in your cave diving.. The ameba can be found in lake or river sediment at temperatures well below where one would find the ameba in the open water into temps such as mid 80's. The hard flow will also help keep the parasite down in the spring. It can grow I'm temps that reach freezing, however it is very rare to find it below 73ºF.
Hope that helps some.
