COOKING
WATER
DRINK PLENTY OF FLUID each day, in cold weather as well as warm. Drink enough so that your urine remains clear-at least two quarts a day in normal conditions and up to eight quarts during hard exertion in hot, dry climates. Bring the water from home or use the water from public supplies. Water collected from springs, lakes, or streams must be purified before use.
Public Supplies
Water from faucets and drinking fountains in campgrounds and Scout camps usually has been tested by public health officials. It is almost always safe to use.
Open Water
Water taken from streams, lakes, and springs could contain bacteria and parasites too small for you to see. Disinfect any water that does not come from a tested source.
Water From Snow
On winter trips and hikes in high mountains, you can get your water horn melting than snow. Gently heat a pot of snow over a stove or fire. A cup of water in the bottom of the pot will speed the process.
