There is a lot of research out there about spring water bottled. This water is filtered at the source of the spring and then possibly can be treated with chemicals like fluoride.

As for collecting and drinking natural spring water I would recommend taking a sample and having it tested for contaminants. Contaminants can leak into the water table from miles and miles and miles away and up to over a hundred & fifty feet. So although it may be coming from the ground it still may be contaminated, best to check.

I am now going to be purchasing this portable reverse osmosis machine from this company. And I will get back to you when I try it out and see how it works.

Much much love in your adventure.
