Chlorine and iodine have a negative effect on your thyroid gland. Don't drink these things. I suggest boiling all the water as you need it or 1 to 2 gallons in advance for cooler water and that's only if you have reason to suspect it is contaminated.
Store water now. We use the large apple juice bottles (2gal) and change the water in them every few months. Like they said above, don't store them in sunlight, keep them in an unused closet or cabinet. Put some water in the empty bottles and shake it vigorously to clean it. If it has any juice in it, bacteria will form feeding on the sugar in the juices.
For gathering water from exposed natural sources, I suggest a portable filter. Some are very compact. One micron, as stated above.
