One suppposes that rainwater, wellwater and stream water would be free,
if you can access it. Maybe this lady lives in the city and is only
familiar with tap water.

Most people are aware that there is a controversy surrounding public
fluoridation of drinking water. Here is a list of ways to obtain
drinking water without fluoride. In addition, I've listed water
purification methods which do /not/ remove fluoride from water.
*Ways to Remove Fluoride from Water*
* *Reverse Osmosis
<http://chemistry.about.com/od/waterchemistry/a/reverseosmosis.htm>
Filtration*
This is used to purify several types of bottled water (not all), so
some bottled waters are unfluoridated. Reverse osmosis systems are
generally unaffordable for personal use.
* *Activated Alumina Defluoridation Filter*
These filters are used in locales where fluorosis is prevalent. They
are relatively expensive (lowest price I saw was $30/filter) and
require frequent replacement, but do offer an option for home water
filtration.
* *Distillation Filtration*
There are commercially available distillation filters that can be
purchased to remove fluoride from water. On a related note: When
looking at bottled water, keep in mind that 'distilled water' does
not imply that a product is suitable for drinking water and other
undesirable impurities may be present.
*These Do NOT Remove Fluoride*
* *Brita, Pur, and most other filters.*
Some websites about fluoride removal state otherwise, but I checked
the product descriptions on the companies' websites to confirm that
fluoride is left in the water.
* *Boiling Water*
This will concentrate the fluoride rather than reduce it.
* *Freezing Water*
Freezing water does not affect the concentration of fluoride.
*Steps to Reduce Fluoride Exposure*
* *Don't take fluoride supplements.*
* *Read labels on bottled beverages.*
Unless they are made using distilled or reverse-osmosis water, they
are probably made with fluoridated public water.
* *Consider using unfluoridated toothpaste.*
* *Avoid drinking black or red tea.*
There are many health benefits associated with chemical compounds
found in tea, but this may be a beverage to avoid if you need to
reduce your fluorine intake. Black and red tea come from two
different types of plants, but both leaves naturally contain high
amounts of fluorine.
* *Be wary of tinned fish and canned food items.*
Fluoride may be used as a preservative.
* *Avoid black or red rock salt or items containing black or red rock
salt.*
* *Avoid using chewing tobacco.*
* *Avoid long term use of medication that contains fluorine.*
Certain antidepressants and medications for osteoporosis contain
fluorine.

RO and Fluoride
According to a 2008 University of Nebraska guide, reverse osmosis can
remove many typical impurities from water. These include dissolved
minerals such as calcium and magnesium, as well as solid particles and
pesticide contaminants. The guide states that RO systems will remove
fluoride ions from water. This guide also notes that RO units can be
configured to produce enough fluoride-free water for an entire
household, and recommends that a reliable water treatment dealer be
consulted to choose and install the most appropriate
