If you want to have your water tested for metals the Department of Natural Resources has a webpage of laboratory listings for a lab nearest you.
Corrosion can occur when water reacts with metal plumbing.
Corrosion can cause unsafe levels of lead and copper to dissolve into your drinking water. It may also eventually cause leaky pipes, faucets, hot water heaters, or other plumbing fixtures.

Lead can be especially dangerous to young children, infants, and the unborn.
