[Bored chemist]

We shouldn't ever get fringes underwater if everything is decohering.

My diffraction grating popsicle shows that you are wrong.
This is no great shock.
You started off by saying

H2O atoms are not bonded to other H2O atoms.

which is not even wrong.
There's no such thing as a water atom.
And water molecules are quite strongly bonded to eachother (in the condensed phase) which is why water has a much higher boiling point that, for example, methane or hydrogen sulphide.

So, it's pretty clear you do not know what you are talking about.
