Here is some useful information on purifying water for use, whether it is stored in barrels at home, or collected elsewhere:
1. If water is cloudy, smelly or therwise polluted, strain it through a paper towel or several layers of clean cloth into a container in order to remove any sediment or floating matter.
2. Water that is boiled vigorously for one full minute will usually be safe from harmful bacterial contamination. Boiling for 3-5 minutes is safer, if you have heat to spare.
3. If boiling is not possible, strain the water as above and treat by adding ordinary liquid chlorine household bleach (4-6% chlorine) or tincture of iodine (from your medicine chest–2%chlorine) in the following amounts.
a. CHLORINE: Add 2 drops (with eye dropper) per quart of clean water, 4 drops per quart of cloudy water. (This equates to 1/2 tsp. per 5 gallons of clean water, or 1 tsp. per 5 gallons of cloudy water.
FOR A 55 GAL. DRUM, USE 2 TBSP / 4 TBSP. of bleach).
b. IODINE: Add 5 drops per quart of clean water, 10 drops per quart of cloudy water.
Mix thorougly in container. Let it stand for 30 minutes. A slight chlorine odor should be detectable in the water; if not, repeat the dosage and let the water stand for an additional 15 minutes before using.
It is a great idea to store powdered drink mix to improve the taste of stored water. Drink mix and disposable drinking cups should be part of your emergency supply.
Thanks Kim. Also, what a find with that pgward.org site. What a great wealth of information.
Here’s a six page document I put together a few months ago on water storage/purification that might be of help on this issue.
Have not thought about drinking cups or using mix until now. Thanks for the info.
