Bleach Water Purification

CostCo sells two-packs of one-gallon bottles of un-scented, no-dye bleach. One gallon of bleach will purify an absolute crap-ton (a scientific term) of poop-infused water, so it’s handy to have around the house, flat, apartment, boat, cabin, or Undisclosed Location.

There are a few ratios of bleach-to-water on the interwebz. The WA state USA Department of Health guys seem to be on the “more is better” end of the scale, which I think is good for water that may have poop floating around in it. I’m generally not a fussy drinker, but I do draw the line somewhere.

Their page is here. From this page, we have this excellent chart:

Treating Water with a 5-6 Percent Liquid Chlorine Bleach Solution
Volume of Water to be Treated Treating Clear/Cloudy Water:
Bleach Solution to Add
Treating Cloudy, Very Cold, or Surface Water: Bleach Solution to Add
1 quart/1 liter 3 drops 5 drops
1/2 gallon/2 quarts/2 liters 5 drops 10 drops
1 gallon 1/8 teaspoon 1/4 teaspoon
5 gallons  1/2 teaspoon 1 teaspoon
10 gallons 1 teaspoon 2 teaspoons

I already had a bleach bottle cached away for poopy water so I printed
off this table (on label paper no less!), put it on the bottle, and then put some clear packing tape over that for good measure. Because you never know when zombie blood might get on your bleach bottle and ruin your print-out…

Some people might not like the flavor of bleach in their water. The apocalypse might not cure that. For these folks, a bunch of activated charcoal in a 5-gallon bucket with some holes cut in the bottom should sort that out. JUST NEVER PUT UN-BLEACHED POOPY WATER DIRECTLY INTO THE CHARCOAL, for hopefully obvious reasons.

Speaking of which – if you can actually SEE poop in the water, some filtering before the bleach is likely in order – even just an old tee-shirt will do for that.
