Water Treatment

Sawyer Water Filter

Water treatment is essential!
Water cannot be freeze-dried nor is it practical to carry enough for an extended trip. In the Northern (non-agricultural areas) canoe areas the most common waterborne pathogen is Giardai sp. It’s a common protozoa that once ingested will cause a condition commonly referred to as “Beaver Fever”. Symptoms appear a few days after ingestion and usually include severe diarrhea & fever.

Many people, including myself, have drank untreated water without a problem. Giardia spores are heavy and sink to the bottom of clear calm lakes I would strongly insist that you treat all water before use. The following methods will ensure all bacteria, protozoa and viruses are removed they will not ensure that the water is free of chemical contaminants so in areas where heavy agricultural or industrial activity are suspected or existup stream; take the ultimate precaution and bring bottled water. Be forewarned, that in warm weather it is easy to consume at least 4 liters (1 gallon) per person per day.

BOILING

Traditionally used and considered the most reliable method for treating water Just bring the water to a boil for one minute will ensure that it is free of all common pathogens and viruses. Although it is the most reliable method it tends to require quite a bit of fuel and if fires are restricted it may not be practical and tends to flatten out the taste of the water. This can be remedied by vigorously shaking the water or though the use of flavour crystals.

CHEMICAL

Iodine is a cheap and popular method with many people. It is however not recommended for pregnant or nursing mothers or those with thyroid issues. Personally, although more expensive, I prefer Chlorine Dioxide tablets which are commonly available and work against all bacteria, protozoa and viruses.
