How To Purify Water Using The Sun

The water should be from a clean, well known water source, such as a lake or stream. Running water is best. Avoid standing water; smelly water; water with an oily look; and water near latrines and sewers.

The ambient air temperature is not a factor, it is the strength of the UV sunlight that is significant. If there is a question about the proper length of time because of the sky conditions, it is best to err on the side of caution and allow the full 2 days of exposure.
