Water Purification Tablets
When you follow the directions on the bottle carefully, they will take care of most water borne diseases. Check the label to determine what disease organisms it is effective against. Chlorine bleach and 2 percent tincture of iodine is also effective. Use 10 drops of either in one quart of water. All three methods of water purification require a minimum of 30 minutes contact time. Do not cut the time short. If your water is very cold or cloudy, give additional time.
