Aside from that collected in the form of rain water, fresh water did not, for a long time, exist. Thus, it became necessary to come up with a simple spell which can be cast by nearly anyone to create fresh water from salt water. To that end, some of the most talented wizards and other spellcasters in the world simplified purify food or drink so that any caster (aside from those who can already cast the original spell) can use it with a minimum of learning or talent.
Desalinate works as purify food or drink, but it serves only to remove the salt and impurities from seawater. It has no effect on any object other than water, and it has no effect on any object that is already affected by any spell or magical effect.
