I enjoy the taste of water in Carlsbad, NM (lots of
dissolved limestone!), but not Denver tap water, which
is also classified as "hard," so I filter before I
drink (I also live in a 1940's house, and lead is
detectable if the water has been 'sitting in the
pipes' over a long weekend).

There can be some benefits to mineral water:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=12449291&dopt=Abstract
...RESULTS: Dietary calcium intake provided by the
various food groups did not differ between the 4
consumer groups, except for calcium provided by
mineral water. According to its calcium concentration,
mineral water may contribute to one fourth of the
total daily calcium intake. Subjects who regularly
drink mineral-rich water have a calcium intake that is
significantly higher (P< 10(-3)) than those drinking
either low-mineral-content water or tap water. Dietary
magnesium intake provided by the various food groups
did not differ between the 4 consumer groups, except
for magnesium provided by mineral water. Depending on
the magnesium concentration of the mineral water, it
contributed 6% to 17% of total daily magnesium intake.
Drinkers of magnesium-rich mineral water and water
with a moderate mineral content had magnesium intakes
significantly (P< 10(-3)) higher than those of
drinkers on low-mineralized or tap water.
APPLICATIONS: Mineral-rich water may provide an
important supplementary contribution to total calcium
and magnesium intake. For dietetics professionals, it
may provide-in place of the usual recommendations
concerning the consumption of dairy products-a good
way to improve calcium and magnesium intakes,
particularly in subjects who don't like dairy
products.

(There were several other studies about calcium and/or
magnesium intake WRT mineral water; some studies
looking at effects (frex, calcium-rich water and
possible effect on renal stone formation) are both
quite small, and - when using "normal" individuals as
subjects - may not apply to the affected group.)

This abstract had nothing beyond the conclusion, but
suggests that certain skin problems are improved by
mineral water consumption:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=12325458&dopt=Abstract
Deep sea water intake improves skin symptoms and
mineral imbalance and decreases serum IgE levels...in
patients with atopic eczema/dermatitis syndrome
(AEDS), while distilled water intake fails to do so.

Kevin (I think) asked about tooth decay and distilled
water; while I found nothing in PubMed to suggest a
relationship, there may be some benefit to
mineral-containing water WRT tooth enamel:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11556958&dopt=Abstract
...Thus, mineral waters appear to offer a safe
alternative to more erosive acidic beverages and their
complex mineral ion compositions may positively
influence any dissolution processes at the tooth
surface.

However, high sodium chloride may negate the benefits
of a low-salt diet (for hypertension):

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=12013486&dopt=Abstract
...CONCLUSION: Consumption of sodium chloride-rich
mineral water can abolish the blood pressure reduction
induced by dietary salt restriction in elderly
individuals. Sodium bicarbonate-rich mineral water in
conjunction with a low-salt diet may have a beneficial
effect on calcium homeostasis.

When used to make infant formula, it can also affect
blood pressure:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11821704&dopt=Abstract
...CONCLUSIONS : Diluting milk formula with tap water
containing a high concentration of sodium will result
in the infant being fed a high-salt diet. To
equilibrate with breast milk, formula should be
diluted with low-salt water. Blood pressure in the
neonate is increased by a high sodium intake via
drinking water.

But the source needs to be considered; if they don't
test for impurities (I'd assume that info should be
available on their website; Denver Water sends out a
report to customers each year, listing what they test
for and how Denver scored in relation to national
standards), you may be getting more than you wanted:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=12141610&dopt=Abstract
Radioactivity in some Tunisian thermo-mineral springs
(11 hot mineral springs and one cold spring) has been
determined for the first time in Tunisia using
radiochemical separation procedures. The obtained
results show that 238U activity concentrations vary
between 1.5 and about 43 mBq/l... Radioactivity in the
only cold mineral water from Ain Oktor is very low,
and thus health hazards due to the consumption of this
water are not expected.

Distilled water had the lowest radon levels in this
study:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=8061662&dopt=Abstract
Tap water, flushing water and drinking water including
natural mineral water, artificial mineral water and
distilled water have been investigated for their radon
concentrations. It has been found that the radon
concentration in natural mineral water samples is the
highest and that in tap water is the second highest,
while other categories have values very near to the
detection limit. 

This tiny study adds another reason for Julia's
caution WRT infants and plain water:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11803176&dopt=Abstract
This study in 10 term infants investigated the effects
of different fluids on the coordination between
swallowing and breathing during bottle feedings.
Sucking pressure, swallowing, breathing and O(2)
saturation were examined in each infant during bottle
feedings with breast milk, formula and distilled
water. When receiving breast milk, the infants showed
a significantly higher breathing rate than with the
other liquids. Swallows followed by inspiration were
demonstrated less often with breast milk compared with
formula or distilled water. In conclusion, expressed
breast milk is suitable for neonates because better
coordination between swallowing and breathing could be
obtained and subclinical aspiration could be
prevented. 

Regarding chlorinated tap vs. distilled or
non-chlorinated, there is a trade-off: greatly reduced
GI illnesses like typhoid fever, with small increased
risk of certain birth defects at high levels of
chlorination/byproducts (per large studies published
2002; earlier studies either found only a 'possible
link' if at all, and frequently suggested the need for
larger studies), and possibly some cancers:

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=9273924&dopt=Abstract
This review discusses the relation between by-products
of drinking water chlorination and cancer in the light
of present toxicological and epidemiologic evidence.
During the chlorination of drinking water, a complex
mixture of by-products forms from chlorine and the
organic and inorganic compounds present in raw water.
The quality and quantity of such compounds depend on
the specific nature of the organic material in raw
waters, the inorganic material in raw water, pH,
temperature, other water treatment practices, and the
chlorine timing and dose added. Chlorination
by-products are important mainly when surface water is
used for drinking water as more organic compounds are
present in surface waters than in ground waters. The
gastrointestinal and urinary tract are the cancer
sites that are most often associated with the use of
chlorinated surface water or with the quantity of
chlorination by-products in the water-supply network.
Yet the microbial quality of drinking water should not
be compromised by excessive caution over the potential
long-term effects of disinfection by-products because
the risk of illness and death resulting from exposure
to pathogens in untreated drinking water may be
several orders of magnitude greater than the cancer
risks from chlorination by-products.

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=12181108&dopt=Abstract
To assess the effect of water chlorination by-products
on specific birth defects, the authors conducted a
nationwide cross-sectional study of 285,631 Norwegian
births in 1993-1998. Risks of birth defects according
to four chlorination by-product exposure categories
were compared on the basis of chlorination (yes/no)
and level of water color (mg Pt/liter), representing
the amount of natural organic matter: high...medium.. 
..and low exposure, with no chlorination and low color
as the reference category. In logistic regression
analysis, the risks of any birth defect...[was]
significantly associated with exposure (medium and
high combined). Regarding risk of specific birth
defects, only that for ventricular septal defects was
significantly elevated...Furthermore, risk of neural
tube defects was related to high color...

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11834464&dopt=Abstract
Concern for exposures to drinking water contaminants
and their effects on adverse birth outcomes has
prompted several studies evaluating chlorination
disinfection by-products and chlorinated solvents.
Some of these contaminants are found to be teratogenic
in animal studies...The studies of THMs
(trihalomethanes) and adverse birth outcomes provide
moderate evidence for associations with SGA (small for
gestational age), neural tube defects (NTDs), and
spontaneous abortions. Because fewer studies have been
conducted for the chlorinated solvents than for THMs,
the evidence for associations is less clear.
Nevertheless, the findings of excess NTDs, oral
clefts, cardiac defects, and choanal atresia in
studies that evaluated TCE-contaminated drinking water
deserve follow-up.

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=9504283&dopt=Abstract
...These ecologic data are compatible with
trihalomethanes in drinking water being either
unrelated or weakly related to breast cancer risk.

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=9778177&dopt=Abstract
...A small, statistically significant,
exposure-related excess risk was found for kidney
cancer for men... 

It is harder for the body to absorb pure water than
water mixed with a few electrolytes and a little bit
of sugar.  That is why when infants/toddlers have
diarrhea/vomiting, something like Pedialyte is
recommended as rehydration fluid rather than straight
water.  Same goes for an adult with vomiting - you're
less likely to throw up something like weak tea with a
spoonful of sugar, or diluted fruit juice, than plain
water.  OTOH, concentrated sugars, as in straight
fruit juices or colas, are *not* good for young
children who are dehydrated/nauseous, and can make
diarrhea worse (despite the old-timey nausea remedy:
Coca-cola syrup, which worked, according to some older
patients ).
