Here is the basics ....

Preparing Water to Drink
There are a number of methods used to purify biologically contaminated water in order to make it safe to drink. When using these methods it is important that you do not cross-contaminate water you have purified with water that has not been treated. For example, do not collect suspect water using your canteen, pour this into a container for treatment, and then pour the treated water back into your canteen.

Of all the water treatment methods, I am a strong advocate of boiling water to make it safe to drink. Boiling your water is the number one method of ensuring you have destroyed all disease causing organisms. These organisms will not survive a boiling, but they often can survive the various chemical treatments and filters on the market today.

How to Boil Water to Make it Safe to Drink
The old adage that you should boil water for ten or 15-minutes in order to make it safe to drink is incorrect. You will only be wasting fuel.

Water temperatures above 160 degrees F will destroy all pathogens within half an hour. Add another twenty-five degrees to 185 F and that time is reduced to just a few minutes. The fact is, once you get the water to a rolling boil (212 degrees F at sea level) your task is finished: the water is now safe to drink. Even at high altitudes where the boiling point of water is below 212 F, the water is still hot enough to have completely destroyed any disease causing organisms.

Actually, there are organisms that can live in extreme temperatures.  I think they are called thermophiles.  So I still think boiling for 15 minutes would still be a good idea.  I still would like to know how to make my river water safe to drink with chemicals from factories in it.  I don't think just boiling will kill those factory chemicals.

Do you think distilling water would remove all chemicals in addition to other impurities?: http://www.fleetsubmarine.com/fresh_water.html

It seems there should be an easier way available to produce fresh water. Perhaps an alcohol still could suffice and achieve the same end result?

"there are organisms that can live in extreme temperatures.  I think they are called thermophiles"
True, but what is their ecological niche?

From http://spider.ipac.caltech.edu/staff/jarrett/LiU/class/Project/thermophiles.html :
"Organisms which live in extraordinarily heated climates are called thermophiles. Thermophiles (means “heat lovers”) live in such places as deep-sea hydrothermal vents, inside volcanoes, and in the hot springs of Yellowstone Park. Those which can withstand temperatures above 80 C are usually referred to as hyperthermophiles. These recently discovered organisms force us to look outside the box and expand our current perception of the habitable zone."

Ryan:
Good stuff.
It's important to remember that there's a difference between water 'filtration', and water 'purification'. The filtration isn't guaranteed to take out the microscopic bad stuff. Gotta boil or pasteurize or use special tablets.
