I am going to take a different position than some of you on this matter. But - it is only because I have experienced "mineral enriched" water that darn near killed me. Not kidding a bit. ( Not going into it here...PM me if you want my files on Uranium in well water - and why you may not know it or other heavy metals are there - and the health risks.)
If All you drank was water, and did not take in anything else - then, fine...I would agree with the concern about "over-purified" water via Reverse Osmosis. But - that is not the case. anything else that you consume - contains minerals, as well as other nutrients. ANY sodium, magnesium, calcium ( and a host of other minerals) provide electrolytes which encourage or allow for adsorption an utilization of said food intake. All you need to do is ensure that you have good dietary nutrition. I know that there are some of us that joke about "no greens" - but I assume that you also know of their value to your health - chiefly iron and other essentials.
What I have learned, and in a very hard manner, financially and my health - is that the ONLY way to ensure that you are consuming "clean" water is via Reverse Osmosis. Not even distillation can isolate and remove some VOC's or petroleum components, agricultural pesticides, etc..... And - ANY mechanical or even ionic filter cannot differentiate and separate all of the "other molecules". No filter can identify ions that are good -from those that are bad and separate the good water from the bad and send you only the good water.. It just is not possible at this point in a filter that will fit in a home.
Unless - you "strip" everything from the water. And that is only accomplished in a practical way with R.O. Specifically, a TFC membrane equipped R.O. system, with a pressure pump to maximize the efficiency of the system. R.O. does not work most efficiently at house pressures. As well -- you can set up an R.O. to be as efficient as a 1- to - 1 product to reject ratio.
This is much better than the old 4 to 1 systems from a few years ago.
There are numerous resources that I would encourage each of you to read and research from. But, here is something that we ALL know: You cannot know what is in your water. Because - it changes from day to day. You cannot control, or know when crops are sprayed up-stream from your well's aquifer. Or - that of your city or county water resource, whether that is a river, lake or well. And - because you cannot control that on the input side of the equation - and even the best municipal systems are fluid - meaning, constant thru put ...They cannot stop to test every gallon sent to your home. It is not possible. Nor - do the drinking water labs where your water may come from via a city or county water system or their techs have the equipment at their disposal to test for all of the pollutants (including naturally occurring heavy metals) that can and do occur in "normal" tap water. Do not bee fooled into thinking that your water came "from the mountains" - so it is "above" any pollution. Underground aquifers that feed rivers and wells do not all flow downhill - as based on surface topography.
In the 1970's the philosophy about water purification was "The answer to pollution is dilution". Folks - that just is no longer true. That world is dead and gone. We have over polluted that only resource that we cannot do without.....And - if you doubt what I write here, then ponder this for a moment:
Every time a toilet flushes - there is not just the high probability but a certainty that hormones, antibiotics, anti-depressants and other mood modifiers, and ADD meds. are going directly into the plant that processes your water. They cannot be all completely removed by municipal filtration means and methods. And - if you are on a well - you have even LESS potential filtration, other than layers of what ever geologic rock formation and soils are between you and the source of pollution.
Don't lull yourself into thinking that because you can't see, smell or taste anything - that the water must be good. I will assure you, it can kill you and be great tasting at the same time.
