How can I tell if my water pipe is lead?

Short answer

Find where the water line enters your home, usually near the meter. Lightly scratch it with a coin or key. Lead is soft, dull gray, scratches to shiny silver, and a magnet will not stick. Galvanized steel attracts a magnet. Copper scratches to a penny color. Confirm with your utility.
