Lead levels may exceed overly protective federal standards, but there is no evidence anyone is being harmed.
Every substance is toxic at high enough doses. But no child — not even anyone in Flint, MI — has been shown to have dangerous level of lead in their blood. All children have blood lead levels way below what anyone over the age of 35 or so grew up with. It is false that any exposure to lead is dangerous.
USA Today alarms:
in my village in france (and obviously numerous others) the first municipal water supply was in the beginning of the 19th century using lead piping. Till this day i still have a mains lead pipe stuck to my house, as do many others. No clusters of mental problems related to lead apparent in France since the 19th century till now.
Lead water piping theory falsified
