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.

    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.
