And all have MCL (maximum contaminant level allowed)...

I'll have some wine, thanks...

Fluoride is not added to tapwater in Japan...

I was taking a big overview without clarifying... That's a list (from a city in the US) of SOME of the potential contaminants tested for; the list of possible contaminants for any city would be larger, of course.
In Japan's big cities, many of which (I'm thinking particularly of Osaka here) get their water downstream from a long urban/industrial upstream, I expect fluoride (if added) would be their only problem with a positive aspect...

So how much is it going to cost me to test for all of these in my well water, I wonder?

Well now I don't feel so bad that I never come close to drinking enough water every day....maybe I'm better off. Well, it makes me feel better to think it.

I do wonder if they test the wine I like to indulge in too. And who are "they"? Maybe we had better not try to clarify...
