    john do you mean if it breaks down by sunlight or do you mean is it diluted by more water? If you mean by sunlight then yes i think it does break down.

    Read-Only: umm ground water isnt able to be drunk mostly, the salt content is to high as is the levels of heavy metals. It requires ALOT more treatment than rainwater does at the very least.

    I do know you can get it because my cousin and her husband have put in a bore for the garden but its no good for drinking water. Actually its no good for showering or any inside use, end up dirtier than when you started, as do your cloths and it also has a tendancy to destroy plumbing which is why you cant use it in the toilet (apart from the fact that its BROWN)

    It is a gas, it dissipate into the air. If it is agitated it will dissipate quicker, the sun is not, afaik, a factor,

    put it this way Read-Only, there was a suggestion to use some ground water that isnt part of the great arteasian baisin (can use GAB water because the murry system is already bad enough and if we take its ground water to it would be royally FUCKED). The reason this was suggested was because the desal plant needed to make the water usable wouldnt have to work as hard because its only about half as salty as sea water.

    So if you were to put a RO unit in your house i surpose you could use the ground water but as i looked into getting one and they are VERY expencive (plus you then have to add some of the salts and stuff your taking out again anyway) rain water where you dont have a polution issue is a much better solution. The reason rain water for drinking is illegal in the cities is air polution. Apart from that as long as your roof is treated with an intert sealer (and they do advertise those now) its compleatly safe

    john come on you have an aquarium, what does it say on the back of the aquarium salt?

    No you cant pull salt out by ANYTHING other than 1) evaporation (uses lots of energy) or 2) FORCING it against its osmotic pressure through a semi permiable membraine (again uses LOTS of energy and there is also alot of waste water that has to be thrown out)

    Though there actually MAYBE a third option which of running an electric current through the water but that will only pull out salts and not any of the other gunk and again takes alot of energy

    carbon will pull out organic chemicals like amonia. I belive it will also remove chlorine (the chemical rather than chlorine salts) and chlorimine but it WONT pull out elements like salts (sodium, potasium, magnisium, chloride ect). I know it also wont pull out floride, the one i just dont know about is lead.

    I know a pura tap only leaves floride and the salts in the water because i asked the guy who was fixing ours if it pulls copper out (copper kills invertibrates

    I knew Australia could be bad, didn't know it was quite that bad. So, I guess that satisfies the conditions which I placed on my initial post.

    I'd have to be pretty hard up to drink water that ran off my roof. Seems like you're pretty hard up out there. So, chug-a-lug.

    Ingenuity and all that.

    IN at least i know for a fact that no one has pissed in the rain watter. If you get your water out of a stream god knows how many people have showed, pissed in it ect.

    Also you can NEVER get choloria from rain water nor i belive can you get criptosperidium (something i know for a fact contaiminated the water in sydney)
