Iodine will work, but there have been some medical problems associated with it's use. Clorox is very capable of purifying water and it is MUCH cheaper. 4 drops will treat a quart of water. Double it if it is cloudy. Double it again if the water is below 45*F.

Just be careful that the container is leak proof.
