My world is a life-bearing moon orbiting a gas giant. There will be plenty of geysers due to gravitational tectonic activity. Is it possible for geysers to happen in the middle of hot and arid biomes? If yes, could they serve as drinking water?

What I imagined is that hot and salty water is violently expelled and then stays in puddles where bacteria separate the salts and other noxious elements from the water.

With the water being purified in such a way, could it serve as drinkable water and could life forms thrive inside this bacteria-rich pooling water?
