Rain is nearly pure water rain usually contains a small amount of harmless bacteria and may also be contaminated by various forms of air pollution. It is not salty unless the rain happens to fall through a blown cloud of salt from a nearby salt flat, which is extremely unlikely as salt flats tend to form only in places that have extremely infrequent rain. Rain at sea will be pure, fresh water, fit to drink. The rain that falls into the sea actually reduces the salinity of the seawater somewhat. The salt that is in the sea comes overwhelmingly from land, carried there by rivers.
