Are You Putting Your Health in Hot Water?

"When you're in a rush, it's tempting to use hot H2O from
the faucet to brew your Earl Grey. But this shortcut can expose
you to contaminants like lead, copper, and rust. "Hot tap water
is more likely to leach these compounds from your pipes," says
James M. Symons, the author of Plain Talk About Drinking Water.
That may put you at risk for potential problems, such as lead
poisoning. For the safest sip, bring cold water to a boil."
