One idea is that all the bodies in our early solar system were bombarded with water containing objects, explaining how Earth got its water. Water
would have likely been delivered to the moon in a similar process, so the question then becomes, how much of that water can it hang on to? Not much on
the surface, obviously, with the exception of polar craters, but water in the pore spaces of underground rocks shouldn't be too surprising. Even if it
was icy rocks that impacted the moon, the impacts could have liquified the water allowing it to flow underground. Earth too has lots of water
underground, and since the crusts are made out of similar porous materials, why shouldn't the moon also have water underground?
Now, the state of the water, liquid versus ice, would depend on the thermal gradient of the moon's interior. Do we know what that gradient is? I don't
think it's ever been measured, though we might be able to guess at it, using models.

I remember seeing a video feed from a satellite showing a geyser shooting on the moon
But cant find it again.. If anyone know it please reply the link to me
I never saw that from Earth's moon.
Were you thinking of Saturn's moon?
