Excellent question, Michael. I also have questions about the "Ozonated" process that is indicated on my supplies of distilled water. It does state it is purified by steam distillation, filtered and ozonated. I have always wondered if the ozonation process has anything to do with the fact I can never get Xtol to last more than a few weeks before going flat, even though I store in Boston rounds sealed with Saran wrap. Hope someone can address this issue.
I did find this online:
Ozone is a very strong oxidation medium, with a remarkably short life span. It consists of oxygen molecules with an extra O-atom, to form O3. When ozone comes in contact with odour, bacteria or viruses the extra O-atom breaks them down directly, by means of oxidation. The third O-atom of the ozone molecules is than lost and only oxygen will remain.

Since oxidation is a primary killer of developer, is this perhaps what is zapping my Xtol? Is the Purified Water perhaps a better choice? I will check at the market and see which bottled water products are ozonated today.
Apparently the half life of ozone (O3) is about 20 minutes but when that time has elapsed, O3 breaks down into O2. It is my assumption that this is in the form of dissolved oxygen. If so, not good for developer.
