Purifying water before use

With the disaster in Japan March 2011, I thought I would reprint the article I wrote on my website on water purification.

.

When drinking water from an unknown source in the outdoors, make sure to boil it first for at least two minutes, or if your above 2,500 ft. in elevation, three minutes minimum. Only boiled water should be used for drinking, brushing teeth, washing fruit and vegetables, and rinsing eating utensils. Boiling water for tea and coffee and for cooking, you should boil first and then use a filtration system, if it is murky.

 .

Portable filters are convenient for treating outdoor water. In most cases, a small microfilter is used to pass water through filters that remove organic contamination. Most filters use either activated charcoal or extremely fine ceramic mesh, some with iodine, to remove viruses. For most waters, to remove any micro-organism present, filters should have a pore size of 0.5 microns or smaller. To make sure the highest degree of removal when choosing a filter, look for an absolute style, as opposed to a nominal one. You can make your own filter by constructing one from “homemade filter”.

 .

Use carbon-cored ceramic filter systems to treat water while on trips. Your choice of model should be based on ease of use, reliability, durability, and the ability to process large quantities of water in a short time. One of the favourite hand pump filters is the one made by “Katadyn”. You can find this type of filter in Canada at any “MEC” under the hiking/camping section and look for water purification.

 .

Whatever system is used, boiling or filtration, having a spare with a backup filter and/or chemical treatment is important. A knowledge of the system and how to clean, maintain, and repair is important.

  .

Water is a necessity of life, you cannot survive long without it. To make sure you have a fun-filled and virus-free time in the great outdoors, practice healthy routines when drinking, swimming, and washing up.
