You realize that Water goes through the SAME process before it hits your pipes to come out as drinking water. The main difference is that it's just the water distilled, not the rest.
Now, while there is a difference between your drinking water and Distilled water, it still goes through similar treatment. Especially bottled water.
For your regular faucet water:
It's boiled and then filtered. This boils off some of the bacteria that dies in heat. Following this, it's cooled and filtered again. This is because lowering water temperature decreases the amount of minerals and chemicals that can be saturated into the filter. This usually pulls out most of the heavy metals like mercury and some others. Finally, the water is filtered again though another filter before going to the storage tanks. ACtually, the best time to get water, is before it hits the tanks because roughly 40% of the toxins in the water come from when it's waiting in the storage tanks.
Now, bottled water:
Bottled water is first filtered through a numble of filters before being boiled once and then cooled. This removes almost anything that shouldn't be in the water.
Now, with dystilled water, it goes through a bit longer process:
After being filtered numerous times, the water is cooled to near freezing, which results in the solidifying of a number of the dangerous chemicals as well as minerals. The water is then sent through another set of filters before being boiled to steam. It's sent through a tube made out of a conductive material that (somehow) removes excess ions (or something (i'm not a physist)) and then it's cooled back to liquid. AFter this, it's filtered and then the boiling and cooling is repeated. Then, the water is tested for purity before it's either bottled or re-boiled and steamed. Part of the reason dystilled water is so expensive is becuase it takes more boiling and cooling depending on the amount of toxins in the water ahead of time.
Now, that might not be EXACT processes, but it's as close as I can remember from when I took the "field sterilization and water treatment" classes when I was in the Army.
BTW, did you know that it's not only possible to turn urine into drinking water, but not that difficult?
Also, I know how to get water from various other methods from survival training, including blood.
And since WHEN has E Coli been found in poo? Thats found in undercooked meats...
Seriously, tell that guy he's a complete fucking retard and to do SOME research before he tries something retarded.
