Even water out of the tap (be it well water or from city water supply) may be tainted. probably to a lesser degree we hope. Suspect all water found in nature. <br><br>

Everyone I know I recommend getting a charcoal or better shower head filter, (for showers and baths),
and drinking only distilled or good-filtered/ro bottled water.
In a couple days to two weeks (I tell them 2 to 3 months; but they always call sooner than that) , they THANK ME ! Troubles they had with their skin for years often clears up! YEAH!
It does "feel" better all the time - as if getting a water softener , they say right away.....
