Hi Neville,
Our roof has copper gullies between gables and I know other roofing materials 
could be problematic, especially where there is heavy industry nearby, like 
fracking. It's for that reason that I'd never recommend rainwater use to anyone 
whose circumstances I didn't know. That said, and where DW is impossible, 
obviously one chooses the best available, and yes, in a health emergency, I 
don't think less well-made CS, used briefly, would be catastrophic.

My generator simply shuts off if the water isn't void of any contaminants, even 
reacting to prilled water, so that rules here.

As for fluoride, I've brought my son and DIL up to speed as Marin County, CA 
may become yet another place to succumb to fluoride 'disposal' into their water 
mains. So depressing that this can still happen. Like the frackers want to 
dispose of their frack water as 'ice melt ' and 'dust control' in poor counties 
and townships where snowy roads are an issue and an expense. Like we really 
need benzene, toluene, proprietary toxins, and radioactivity draining into 
local streams, blowing in the wind, etc.

Be well,
Léna
