What is the best source of water for those on paleo? (Lets assume we don't live where there is reasonable access to a well, spring, or some other ideal source that our ancient ancestors might have used.)
It's not obvious to me how to weigh the pluses and minuses of the various options: tap water contains minerals (good, healthy from our paleo perspective) but also chemicals added (bad and not paleo). Bottled water is probably cleaner and safer (good in general) but also has the minerals removed.
I drink filtered water from a Berkey gravity-fed filter system in which I have added the fluoride filters. This filter has been around for a long time and is highly regarded. If I owned my own home, I'd get a reverse osmosis, whole-house filter. But since we live in an apt and travel a lot, we can take the Berkey with us.
A good source of spring water. You may even be able to bottle your own for free, but (as per your question), if we assume you can't, you may still be able to find a distributor (a company that delivers water to homes and businesses) of good spring water close by. To me this makes a lot more sense- just bottle good water at its source instead of worrying about filtering it.
Consider the normal alternative- take (polluted ?) water, filter it some, add a bunch of toxic chemicals to kill pathogens, and send it to your home. At that point you have to filter at the toxic chemicals they added in addition to what might be existing. And filtering out fluoride is a pain. By the time you are done filtering (this is very true in the case of reverse osmosis) you have a mineral-depleted water that needs to be re-mineralized to avoid losing minerals every time you drink water. Spring waters generally has very high amounts of minerals so you can actually gain them as you drink water.
I am lucky to live somewhat close to what some consider one of the best spring water sources in the world, so I get a lot of good minerals without having that bad of an environmental impact. Of course I am using the re-usable large water jugs, so no plastic being thrown away. And I am within walking distance of a distributor, so I get a big discount for picking up the water myself.
I've got no fear of fluoride (my dad's a dentist, I grew up taking fluoride SUPPLEMENTS :gasp: due to un-fluoridated water in my neighborhood), so I'm very happy drinking my city tap water pored through a Brita for taste reasons (kinda coppery from old pipes).
I like the concept of buying a basic mineral filter, and pouring distilled water (available in most grocery stores) through it to add some stuff back to it. It's not a perfect solution, but it's better than the chlorine and fluoride found in most municipal water
