Re: uranium in hair

I believe the EPA monitors U in drinking water as part of the SDWA.  I 
recall compiling a lot of this data a while back, and noted a lot of 
variation in both U and Ra concentrations from less than MDA to 50 or 
100 pCi/l.  The local water supplier would likely have this information, 
though you may have to ask a bunch of them to find the person who files 
the results.
