      Boiling water renders it biologically safe. No giardiosis, etc…

      If you are drinking water with significant heavy metals, concentrating by evaporating a few cups when boiling a gallon, isn’t your problem.

      You’re not even concentrating it that much when you boil it. Keep the lid on the pot next time so you lose less to steam and evaporation.

        Also, “concentrating it” makes it sound like you’re making it worse, but the total amount (mass/moles) stays the same.

        Plus if you build a simple condensation setup, boil the whole thing and drink the condensed steam, you’re also getting rid of 99%* of those heavy, inorganic impurities

        *out-of-my-ass number

      I’d like to read a survival guide based on actual locations rather than old boy scout tricks.

      If you strand on a deserted island in the year 2026 you will find a heap of plastic bottles and other trash that can be made into a solar powered distillery or desalination device. It might still be full of micro plastics but whatever so is the the bottled water in the grocery store.

      Actually if you ever get in a survival situation besides falling off a ship, your best option is probably to rob the nearest grocery store. It’s a great resource that can be found in the most desolate places.

        If you have an entire grocery store to rob what kind of survival situation are you in? Zombies?

          Day to day survival in a lage stage capitalism.

          I’d choose the zombie apocalypse and catastrophic events any day. At least that doesn’t have the existential dread looming over your every move.
