That's distilled (H2O) water I presume, not "heavy water" (D2O) which
has a specifig gravity of 1.107. G Ice cubes made from D2O sink in
regular water.

The town water where our business is located has enough bad taste to it
that I bet it even has a different density.G

There's so much salt in it (from years of road salt finding its way into
the well water.) that the town has to tell all property owners that if
they are on a restricted salt diet, "Don't drink the water."

Interestingly enough, there's no town regulation requiring the property
owners to inform office tenants like us, or apartment tenants. Seems
like they should though. I happen to know about it because we lived in
the town about 19 years ago and they were doing it then. Friends who
live in the same town now tell me they still get notices in the mail
from the town once a year.

We use a "MultiPure" brand filter ahead of our office water dispenser,
and we use the same one at our home in the next town, though the
unfiltered water at home tastes a lot better than the stuff at the office.

Happy Holidays,
