Ephemeral….thanks. I’ve researched this topic for years and that was a clear/concise explanation. Potable water is complicated. Getting some of the bad stuff out is good. Getting MOST out is much, MUCH better.
In some circumstances, you do the best you can. And your best should include something in your EDC. Like the gal they finally located in the Maui forest, she took a chance but kept hydrated. If she had any type of water device, she would not have risked as much with pig/bird poo, etc. Dehydration would have killed her before her rescue. Certain contaminates could have done that also.
