Hi Dale, In a word, dosage. Copper as a nutrient is needed in microgram amounts. When used topically as in electrophoresis it is used only occasionally. I do not know how much is absorbed into the bloodstream when that is done. I do not know erosion rates of distilled water in copper, but still manufacturers nix it for distilled distribution systems. That is likely because of rapid perforation of the piping and too-high copper concentration in the water. Check with a site listing toxicology information. FDA probably has info on the web.

We had a discussion on this list a few months ago about distilling water using copper tubing vs. stainless tubing. In that discussion it was stated that copper tubing was NOT a good idea because it would produce traces of copper in the water which is (or, was...) highly toxic. This is also one of the reasons for using .999 or better silver for making CS. Copper is often used as an alloy in silver (along with other metals) to harden it. Now, we're being told that copper is good. I don't understand. I haven't been on the list for a while, and perhaps I've missed something. Or, perhaps we were misinformed earlier. Or, perhaps we've evolved....8^} Anyway, I would appreciate a clarification of why copper tubing is not acceptable for a water distiller, but colloidal copper is good for us.
