  • Thank you for the notes on what boiling doesn’t purify out of water. It’s simple enough to boil it and call it clean, but we can forget that the source of the water is very important when it comes to how to purify it. Like you say, runoff from urban areas has to be avoided unless you have a chemical filter. I try to teach that to everyone I meet on the trail.

  • It is said that humans need to take several glasses of water per day, and, therefore, it is save to say that hikers and people in the outdoors should take even more water than a normal person, because they are getting dehydrated in the process of doing whatever they are doing. However, just taking water will not cut it. The water needs to be as safe to drink as possible to avoid possible illnesses as we try to flush out toxins from our bodies.
