Hi Dale, Unfortunately you are citing another example of junk science pobular knowledge. "...they only know that drinking water from lead pipes (or with leaded solders) is bad for you." The first part refers to the Roman aqueducts that contained lead linings and pipes—a study I read not too long ago actually attributes the Pb-poisioning of the roman nobility to the fact that they drank their wine [acitic] from Pb-leaching vessels [Brian, please correct me if I am wrong on this]. the second one with the Pb-bearing solder used to solder copper water pipes is definitely a red herring. In New Jersey, the copper pipes were initially replaced with PCP pipes—these leach indefinitely, but what was worse, they sand blasted the Pb-containing paint off of highway bridges [how many kids have you seen chewing paint off of a highway bridge?] which of course made it air-borne and thus contaminated the backyards of people's houses close by.
