One of our daughters is a bottled water freak and refuses to give it up. She say's it's ok because she recycles - whatever.....
We've been on well water every place we've lived for the last 42 years. As for back-up water, I keep about 2 dozen milk jugs (yes, they're plastic)
filled with water mostly for when electric goes out. I change them out, using them to water stuff, to keep the water fresh.
I buy bottled water whenever we travel or visit anyone as I can't drink city aka fluoridated water. Makes me sick.
I was able to find 1 gallon canning jars and I use them for ice water in fridge, orange juice, my smoothie, etc. We have a second fridge in the garage and I keep a quart canning jars in there of water for when I'm working in the garden.
