First off, Bert, it is Comet Tempel, not Comet Temple, and you need to do
more research before making up facts on your own. Read this...

https://en.wikipedia.org/wiki/Tempel_1

... where it says... "Water ice was detected in the ejecta.[7] The water
ice
came from 1 meter below the surface crust (the devolatized layer around
the
nucleus)."

Here is a paper that was written after the data was studied which talks
about the distribution of water on Tempel 1...

http://www.planetary.brown.edu/pdfs/3546.pdf

This paper says that there was not much water near the surface of Tempel 1
but that there was plenty of water everywhere down to about 30 meters
below
the surface. This is not really much of a surprise because most comets
contain lots of water.


*** With every fly-by the exposure to the Sun vaporizes water by
penetrating
deeper and deeper into the passing comets. The vents which expel the steam
actually can change the orbits of the comets, albeit only slightly.



Such an effect they think may be propelling the strange object Oumuamu,
causing it to accelerate as it leaves the solar system. They are more
comfortable believing that than that it might be a self-propelling alien
probe!!!
