This video is Part 6
This video is Part 6 in a series on Backcountry Water Treatment methods.
It is a discussion of Ultraviolet light’s germicidal capacity and the disinfection capabilities of available UV products, including the Steripen. Topics include the relative effectiveness against different pathogen types (cyst, bacteria, viruses), the effect of water condition on performance, safety hazards involved with UV devices, and issues regarding proper use for making water as safe as possible.
