Those pictures make me so sad. I don't know how those people do it and just think of all the illness and death that has to be causing. But yeah, that could easily be us in the not so distant future. Maybe not so much a lack of water, but dirty, contaminated water for sure.
Shoot, I can't even count on "good" water now, lol! The rural water district here has horrible water even on it's best day. It's really hard and tastes bad all the time, and we have lots of notices of this and that being at unacceptable levels.
I just got another notice that there were way high, unacceptable levels of several different heavy metals and bacteria in the water...for almost all of 2013!

They never notify us until well after the fact...gee thanks, what are we supposed to do about it now?
When I first moved out here, I drank the water, figured it was just hard and I'd get used to it. But then my doctor suggested the water might be causing some of the skin and GI issues I was having, and I started developing hemochromatosis liver indices with way too much iron...after being anemic and needing extra iron my whole life. I even had to stop using my cast iron to cook in, wahh! I started using my Berkey daily and the issues got better real quick.
I've been using it regularly ever since, but hate that I have to test it all the time to make sure it's working properly. Even so, after drinking out of my insulated mug all day, by evening it has white deposits on the inside of the cup. I don't like the idea of that coating the insides of ME too, lol, but I don't know what to do about it.
I had always thought with the Berkey I was safe, until Common Tator had her issues. I have a Royal Berkey for the house, a travel Berkey for road trips or camping and a couple of Sport Berkeys for running errands or hiking. But I'm planning to also get a couple of Life Straws and something else bigger for the house, just not sure what yet.
