Water is water, as long as it's not full of moon sand and not radioactive it should be fine
If there really is no water on the moon it's a huge setback. something that can and will be worked out for sure, but delaying a permanent moon-base by a couple of decades at least.
there's no way we will "import" water from earth to the moon, and we can't just, as someone said, condense water there in wet-rooms, that's not how space works.
I reccon we're going to get ahold of an ice asteroid and get the water we need from it.
I've no idea what to write here.
Meh, can't be any worse then water in Mexico.
Radioactive contamination occurs when radioactive materials (like uranium) are dispersed into air, water, dirt. The air, water, and dirt does not in itself become radioactive - it is simply the holding and dispersal mechanism for the radioactive material. The only way for a material to become radioactive is a large flux of high energy neutrons, and ambient cosmic rays do not provide that concentration in short enough periods even to something lacking a magnetosphere like the moon, especially given that 99% of cosmic rays are simply ionized atoms. It is not like a battery where you "charge up" the level of radiation.
I don't believe that using water from the moon with all the effort and technology that would be required to get at it would necessarily be cheaper than just sending supplies from earth and using a water reclamation system on the moon.
They could also use low-radiation weapon designs. It's just some ideas that have been used, but it's likely they'll be used one day. After all, it is not feasible to send an Earth Mover to Mars. Martian Earthbuilders will have to be fabricated there. Barring that, the required underground base any early martian colony will need will have to be built using explosives.
On topic: If you need water there, I'm sure it's possible to gather some asteroid with a decent amount of water-ice on it, and land it on the moon. Or we could just hop the moon and go for Mars or one of the Jupiter moons that we know have water.
