This Google search result and the article it points to, which is
available for purchase from the American Physical Society, may be
of interest to you:

"breakdown voltage of distilled water"

'Electric Breakdown Field Intensity of Water and Aqueous Solutions'
Y. Toriyama and U. Shinohara
Laboratory of High Voltage Engineering, Hokkaido Imperial University,
Sapporo, Japan

Let me know if this satisfies your interests...

They may, but access to the articles requires subscription to the
journal. I do not have access.

The value I am looking for is a particular voltage. I would imagine it
is in the hundreds of thousands of kilovolts, or mabe even megavolts.
Obviously I require substantive source material to verify the voltage

I would like to try to get the value from this Google Answers question
prior to purchasing access to the articles.

         If answer would be a single number, this qestion at this price
could probably be answered. 

 However, the quantity (as described)  is not well defined.

 Breakdown of gas is one thing.  In case of polar liquid, response to a pulse
 would depend om a frequency, temperature, degree of purity ...

   For a DC, do you have any references which shows deviations from the Ohm law?

I suggest you visit a nearby college library, where journals are available for free.

Thank you for the suggestion about the college library, I will check things out.

As for this question, the answer I am looking for is in strick
compliance with Ohms law involving straight DC.

Just to paraphrase my question, I am interested in the voltage that is
required for a pure quantity of distilled water to become conductive.
This is the same phenomena that occurs with lightning as atmosphere
becomes conductive at a particular voltage.
There is no answer at this time.

One doesn't have to pay for the articles from Physical Review.  If you
live anywhere near a college that has a physics department, just go to
the physics department's library (not the main university library)
where they should have a complete set of Physical Review journals.  Go
to page 680 of Volume 51 (from April 1937), and see what it says.
