I've usually observed rust on metal, just above the water line...

Rust is actually a characteristic of iron.
While other metals oxidize...
They are not referred to as rust...
That said...both oxygen (O2) and water (H2O) are required to produce rust (Fe2O3).
Why?
Because that is nature...
The iron oxidizes in water...
Giving off 2 electrons...
These react very quickly with the hydrogen ions and the dissolved oxygen in the water.
If you are concerned...
Lower the pH of the water so it is less acidic...
This should help to thwart off the corrosion of your plant pots...

iron can rust in water as long as there is dissolved air (more particularly, oxygen) in the water as well.
