Every Outdoor enthusiast has asked themselves this question. Microorganisms generally come from human or animal waste and are spread by rain and runoff. A pristine stream may be safe one day and contaminated the next. It all depends upon what's happened upstream. Most of us would like to think that our lakes, streams and rivers are as clean as they are sparkling. Unfortunately, the U.S. Environmental Protection Agency (EPA) reports that 90 percent of the world's fresh water is contaminated. While Giardia is often considered the primary water-safety concern, wilderness studies suggest that many backcountry illnesses are actually caused by bacteria or viruses. Since you never know what's in the water, it makes sense to always protect yourself with a quality water system.

Katadyn's unique products provide safety and convenience for many user groups including militaries, health organizations, and outdoor adventures worldwide.
