Many food products will market themselves around a 4 week / 30-32 day / 1 month timeline for one person. Which was fine for us, because we standardize against two weeks but assume that an average household is two people. So it’s easy to buy a “30-day supply for one person” — assuming the calories per day are appropriate — and use it as a two-week supply for two people.
Potable Water Supply –Your basic supply should be a gallon per day, that will cover drinking and basic sanitation. That is per person, and is a baseline. Hotter climates necessitate more, and some people just need more water. Your next trip out to the grocery, grab at least a 3 day supply. You should have no less than a week’s worth of water on hand for all family members. Get extra if you are storing a lot of food that requires water to prepare.
Anyway, another thought runnin’ round my brain as of late is a mistake Gaye’s friend did, “Yes, you can use oxygenators and all that stuff. I tried that and I ended up throwing out all the food. It was rancid. I processed $1,200.00 of food at a local church facility in Salt Lake City, Utah. I threw it out one year later. It was a volunteer church group that did not know how many oxygenators to put in each #10 can.” – //foodstoragemoms.com/2015/11/dehydrating-food-for-long-term/
