Water Treatment
Should we treat our Water?
It is possible to drink straight from backcountry streams and never become ill. In our opinion, it is not a practice worth the accompanying risks.
Even stream water that looks fresh and clean may contain bacteria, giardia, cryptosporidium and other nasty microbes that could make you ill, or worse.
This is a brief overview to help clean up the confusion surrounding which type of water-treatment system is right for you.
1. Remember the difference between a filter and a purifier. While both remove bacteria from water particles using a mechanical process of pumping then forcing water through a filtering device, only purifiers can render viruses inactive using either an additional chemical or electrostatic process.
2. Waterborne viruses are believed to be less common in North American wilderness waters. But if you're traveling outside of the United States or Canada, you may want to opt for the more involved, and hence perhaps more expensive, purifying system.
3. When comparing filters and purifiers, look for an absolute—not nomimal—pore size of 0.2 microns. This industry wide benchmark indicates the system's smallest filtering capability. No bacteria larger than 0.2 microns can get through. Though a larger pore size of 0.3 or 0.4 may suffice in most situations, why take chances with your health?
4. Depending on its function, a water-treatment system can have numerous parts, some of which will need to be maintained or replaced on a regular basis. If your travel plans include many nights away from a reliable water source, you will not only have to pack the filter but the back-up and replacement parts that go with it.
5. And finally, to get the cleanest water possible be sure to clean and dry your filtering system regularly. When in the outdoors, try to collect still, clear water. Whenever possible, boil the water before treating it. Then, just as if you were seasoning a skillet, let the first few streams of water pass before you begin collecting your treated water.
Free-flowing mountain streams, for all their beauty and clarity, are not always the fountains of purity we imagine them to be. Backcountry water sources — crystal-clear rivers, lakes and streams — sometimes harbor microscopic pathogens (disease-causing agents) that are tough to pronounce, difficult to spell and, for many people, awful to ingest.
Giardia lamblia. Cryptosporidium. Campylobacter jejuni. Hepatitis A. All are members of an invisible fluvial zoo that may be present in pristine-looking backcountry water.
Water becomes tainted by animal or human feces. What impact could such microbes have? They can leave you with diarrhea, abdominal cramps, nausea, weight loss and fatigue. These symptoms can last between 4 and 6 weeks or longer.
