Taking the get out the lead.

I'm Bob Karson with "The Discovery Files"-- new advances in science and engineering from the National Science Foundation.

For a few months after results of tap water tests were released in the nation's capital, a joke made its rounds about the waiter who asks patrons who order water, "Would you like leaded, or unleaded?"

While those results are being questioned and evaluated nationally, a new study is looking more toward the source of lead in the water supply, and how we test for it.

The first place everyone looks is the pipes.

But a group of researchers from Virginia Tech believes there are flaws in the current testing of fixtures. Valves and faucets manufactured using small amounts of lead may, by current testing standards, be certified "safe."

The group's findings indicate that upgraded testing procedures for lead may lead to safer drinking water for all of us.

"The Discovery Files" covers projects funded by the government's National Science Foundation. Federally-sponsored research -- brought to you, by you! Get the full story at Click on "news."
