How to Purify Water While Hiking? Reliable Methods, Professional Equipment & Expert Advice
Whether trekking, bivouacking, or expeditioning, water is your vital resource. Clear water isn't necessarily drinkable : it can contain bacteria, viruses, or invisible contaminants. This premium guide details all the effective methods , the selection criteria according to your terrain, and directs you towards quality equipment tested and recommended by experienced practitioners.
1) Essential principles
Purifying water involves eliminating or neutralizing:
- Bacteria (E. coli, Salmonella)
- Protozoa (Giardia, Cryptosporidium)
- Viruses (hepatitis A, rotavirus)
- Chemical pollutants (heavy metals, pesticides)
- Solid particles (sediments, organic matter)
2) Risks associated with untreated water
Drinking untreated water can lead to:
- Gastroenteritis, severe diarrhea
- Typhoid or viral fevers
- Long-lasting parasitic infections
- Slow chemical poisoning
These problems can interrupt an expedition and put your life in danger far from any help.
3) Reliable methods
3.1 Boiling
The safest method: heat the water to 100°C for at least 1 minute (3 minutes above 2,000 m altitude). Effective against bacteria, viruses and protozoa.
- Advantages: maximum reliability
- Limitations: Requires fuel, stove and time
3.2 Mechanical filtration
Uses <0.2 µm membranes to remove bacteria and protozoa. High-end models combine activated carbon to improve taste and remove certain pollutants.
- Advantages: fast, light, no chemicals
- Limitations: ineffective alone against viruses
3.3 Chemical treatment
Chlorine dioxide or iodine tablets or drops. Effective against most microorganisms, but waiting time of 30 min to 4 h.
- Advantages: ultra-light, easy to store
- Limitations: altered taste, delay
3.4 UV-C Purification
Portable lamp emitting UV-C rays (254 nm) that destroy the DNA of microbes in less than a minute.
- Advantages: ultra-fast, retains natural taste
- Limitations: only works on clear water, requires battery
3.5 Optimal Combinations
For maximum safety: mechanical filtration + UV or filtration + chemistry . This covers almost all biological risks.

7) Technical FAQ
Do I always need to purify water?
Yes, except for a guaranteed potable source (treated network). In nature: always purify.
Are UV rays enough?
Yes, on clear water. Otherwise, filter first to prevent particles from blocking the light.
