This is perhaps unhelpful for those of you who have replied 
to this thread already but for others, I just went through 
the motions of finding out where my water is from and 
thought I'd share this information; maybe someone can tell 
me if this seems wrong.

I found an English description on a government web site 
about how water is supplied in Japan:

http://www.mhlw.go.jp/english/policy/health/water_supply/menu.html

And then on this Japanese Wikipedia page, there is a summary 
of water purification plants.

http://ja.wikipedia.org/wiki/%E6%97%A5%E6%9C%AC%E3%81%AE%E6%B5%84%E6%B0%B4%E5%A0%B4%E4%B8%80%E8%A6%A7

I searched for my area and made the big assumption that the 
plant closest to my home is where my water was from.  Copied 
and pasted the "water supply business" in Japanese into 
Google and on their first page is usually the test results 
(I tried a few because I kept getting my city wrong :-) ).

Of course, I can't make too much sense of the numbers (I'm 
at least assuming increasing numbers are bad...), but I 
think it is a bit better than assuming that Kanto's water 
supply is provided by one gigantic river...the values will 
vary even within Tokyo.  No doubt the media will always 
report the maximum value to us...
