does boiling water for drinking purpose rid the water of fluoride that
has been added to the water supply?

Boiling water will not remove fluoride; it will, instead, concentrate
the fluoride. Here are a few sites that make reference to this fact:

"Boiling Water: This will concentrate the fluoride rather than reduce
it."

About.com: Chemistry

"Fluoride is not removed by boiling, home water softening systems,
sediment filters or ultraviolet systems."

Calgary Regional Health Authority: Fluoridation
http://www.crha-health.ab.ca/pophlth/hp/fluoride/hpremove.htm

"Boiling water will increase, not reduce, the amount of fluoride." 

New Mexico Environment Department: Health Advisory for Fluoride in
Groundwater
http://www.nmenv.state.nm.us/gwb/hafluor.htm

"Remember that boiling water removes dissolved chlorine, but only
concentrates fluoride."

Fluoride Alert: Accidents
http://www.fluoridealert.org/accidents.htm

"Residents were warned by phone and public radio of high fluoride
levels. Officials warned that the more water consumed with elevated
fluoride, the worse the danger becomes, and that boiling water could
concentrate the fluoride even further. Boiling water in preparing
foods always concentrates the fluoride even with 1.0 ppm."

"What about boiling water? Boiling water with fluoride concentrates
the fluoride, rather then eliminating it. The reason for this is
because the fluoride is heavier then water, and while the amount of
water decreases through evaporation, the fluoride does not escape. So
if you were to completely boil the water until there were none left,
you would have only fluoride, and other heavier then water chemicals
left on the bottom of the pot."

Fast, detailed information.Thank you.

Fluoride carries a net (-) charge on it's surface.  Boiling water that
contains fluoride, does not remove this chemical. As mentioned,
boiling the solution, results in an evaporation of water and a
concentration of the fluoride.

Because the fluoride species is charged ( i.e. ionic), it can be
removed from water by using resins called ion-exchange resins.  The
resins bind to charged molecules and not to non-charged, neutral
molecules.  Boiled water, that contains fluoride, can be passed
through the ion-exchanger and the fluoride will still bind to the
resin and deplete the water of the contaminating fluoride.

Only half the answer.

If the steam rising of your boiling water was passed thru any kind of
condenser (see Leipzig condenser) then you would have removed the
fluoride (and all other) contaminants. This is by far the cheapest and
simplest way of purifying water.
