I refilled my water stock at a mountain stream on the side of the dirt road leading to Batopilas. I had run out of bottled water and was parched. Sure, could have waited for arrival in Bato, but point is, didn't have to. City, country, forest, field - if you can find water you can treat it and drink it. I suppose if someone wanted to expand this discussion to what about industrial chemical removal we could be here all day - for the rest of us, the gist is just carry something to treat water and so if you run out of bottled water you're not stuck.
