Here is a company that sells water treatment and storage products. They have a how to section that answers your question. Plus other water treatment solutions.

Gack ! 3 cups for 100 gallons ??? I think that’s what you would add if you were making a solution to disinfect a surface. If you drank water with that concentration I think you’d get poisoned.

I know, three cups sounds like a lot. I promise this was for drinking water, though. The information was with a whole bunch of other stuff about purifying drinking water after a natural disaster (tornadoes and the like). And a hundred gallons is a lot of water.
Not to knock you guys, but Stoidela, why in the wide, wide world of sports are you putting your trust in the SDMB about how much bleach to add to water to make it potable when you should really get out the phone book and call the county health department?! Hell, if I tell you to add one gallon of bleach per 55 gallon drum, would you do it? Would you belive me?
For brief time, (I claim insanity!) I used to manage an Applebee’s and yes, you add two capfuls of bleach to a 5-gallon bucket for use as a disinfectant. And yes, you could drink this mixture. You might get sick but unless you have a weak constitution, you won’t die from it. We also use that same amount to clean the ice machines on a routine basis.

A swimming pool has a huge surface area open to the air. Survival water storage jugs/drums do not. Adding the right amount of bleach to clean water, and then storing it in an airtight container, is supposed to keep the water potable for 5 years.
I once made the mistake of paying $16.99 for a one-fluid-ounce bottle of “water preservative.” The ad on the label read, “Chlorine bleach has never been proven to preserve water, but this product has!”. … I later read the ingredients on the bottle, and they were identical to Clorox, right down to the percentages used. D’OH!
The truth, as always, is more complicated than that.
