How to drink river, spring or lake water in nature completely safely?
There’s nothing quite like a cool drink of water after a long hike. But the most important principle in nature tourism is to never underestimate water. A river or spring that looks crystal clear could contain microorganisms that could turn your trip into a nightmare.
To ensure your health while traveling, you should be familiar with effective water purification methods. Here, we compare the most common methods to help you make the best choice.
1. Microbial Threats: Why is Natural Water Dangerous?
Natural waters, even at high altitudes, may be contaminated with animal or human pathogens. The main threats include:
* Bacteria: such as E. coli, which cause acute gastrointestinal diseases.
* Protozoa: such as Giardia and Cryptosporidium, which cause chronic gastrointestinal diseases.
* Viruses: which can be transmitted through water in areas with high human traffic.
Eliminating these microorganisms is vital to maintaining health.
2. Comparison of Traditional Water Treatment Methods in Nature
| Method | Advantages | Disadvantages and Limitations |
| :— | :— | :— |
| Boiling | Kills 100% of microbes. | Time-consuming: Requires a lot of fuel and takes a long time. Heavy: Carrying the fuel and pot is heavy. Taste: Boiled water has a flat, bland taste. |
| Chemical tablets (iodine/chlorine) | Lightweight and portable. | Odor: Gives water a chemical taste. Slow: Usually requires 30 minutes or more to take effect. Incomplete: May not be effective on some protozoan cysts such as Cryptosporidium. |
| Pump or gravity filters | Removes particles, silt, and some bacteria. | Requires physical effort: Pumping is tedious. Physical only: Does not remove viruses and smaller microorganisms. Cartridge replacement: The filter must be cleaned and replaced regularly.
3. UV-LED: A new era of natural disinfection with PUWA
