How to Purify Water 

Boiling  

If you have electricity available, boil water vigorously for 1 minute.  Filter the water through paper, gauze or finely woven fabric to help remove particles or let particles settle to the bottom, then slowly pour off the clean water. There is no guarantee that this will remove all contaminants.  

Water Purification Tablets  

Follow the directions on the package.  Available at most drug stores, travel or camping stores. 

Bleach Purification  

Liquid chlorine bleach (LCB) should be used.  It must contain hypochlorite, preferably 5.25%.  Let stand 30 minutes after application.

Purification compounds must be in contact with the water for at least 30 minutes to kill the bacteria.  The water must be well mixed. The treated water should have a slight chlorine smell and taste.
