Thanks for clarifying that. The person at the water dept I spoke with
was the one who tests our drinking water, and the way he explained it
was that boiling the water in a covered pot was like distilling it,
albeit back into itself. Personally, I just collect rain water from the
rain gutters and that seems to work fine.
