Why do I need to Purify Water from Rivers, Streams or Lakes?

Purifying water from rivers and streams is essential before drinking. Parasites and bacteria can live in the water, and if you drink it you could end up with a bad belly or worse.

The only exception is if you drink water from an underground spring, where it has been flowing and there is no chance of livestock or other animal faeces or contaminants.

How can I Purify Water in the Wild?

One of the best ways to purify water in the wild is to boil it. But, setting up your stove or building a fire is not always possible or convenient. That is when having a personal water filtration system as part of your hiking gear makes a big difference!

You can also use iodine or chlorine tablets to get rid of nasties in water, however they don’t taste great and you are just adding to the toxic load in your body. But, they will save your life in a drinking water emergency.

By far, the best way of purifying water fast in the wild is to use a filtration system.

Best Places to Get Drinking Water the Wild

  • The best wild water is that which is fast flowing, preferable over mossy rocks. This means that it will have already have some natural filtration.

  • Still water such as lakes and pools can be good sources of water, as long as it looks clear.

  • Avoid water that is stagnant and bad smelling, unless in a life or death situation.

  • Unless you are getting water directly from a spring that is naturally filtered, water must be purified before drinking. If you don’t you may end up with a bad belly, or worse, a serious illness.

Thankfully, with a personal water filtration system, you can safely drink from most water sources.
