[Homeroast] Distilled H2O

"all that benzine (sic)"  I just have to ask, all what benzene?  In 
15 years analyzing for benzene, I never found it once in water that 
was not a ground monitoring well (and not used for drinking).  As for 
what organics, usually those refer to THM's and HAA's - both 
disinfection by products of chlorination.   And all 18 mohm and RO 
systems I ever used had carbon filters also in place to deal with 
removing those low level organics.
