Bleach (No, I don't know what the bleach is for. NOBODY knows what the bleach is for, but it's traditional, so GET some!)

BurgerMeister, The bleach is for treating polluted water. One Tbs. per gallon will do it, BUT make sure it's plain old bleach, not the scented kind. After hurricane Hugo, Charleston, SC's water was bad, my sister heard that one should use bleach to treat the tapwater. She had on hand the lemon scented variety and used it. It gave her whole family what my Granny called "the green apple quick step" AKA diarrhea.
When I arrived 2 days after the storm with 120 gallons of my well water, they were ready to kiss my stinky feets.
