Mini Lesson

A stream can look clear, cold, and perfect to drink. But water in streams, lakes, and puddles can carry tiny germs. They are far too small to see. These germs can make you very sick. That is why you never drink wild water that has not been treated.

🌿 The Wild Way (safe water only)

  • LOOKS CAN TRICK YOU: clear, cold water can still have germs you cannot see.
  • NEVER DRINK IT UNTREATED: not from a stream, lake, puddle, or melted snow.
  • BRING YOUR OWN: carry enough safe water from home for the whole trip.
  • ADULTS TREAT IT: only an adult makes wild water safe, for example by boiling it.
  • KEEP BOTTLES CLEAN: wash your bottle at home, and do not let others drink from it.
  • TELL AN ADULT: if you swallow wild water by accident, tell an adult right away.
⚠️

An adult is always in charge of treating wild water - never try it on your own, and never drink wild water just because it looks clean. If you swallowed some by accident, tell an adult right away. Stay calm - the adult decides what to do.

💡

🧠 Survivor’s Trick: before a hike, fill your bottle at home and check it is full. Take small sips often so it lasts, and tell your grown-up when it is getting low - never fill it from a stream yourself.
