Typically, lead enters your water after the water leaves your local treatment plant or well. Lead can enter drinking water when the water comes in contact with plumbing materials such as lead pipes or lead solder, or when it comes in contact with faucets, valves, and other components. This interaction is referred to as corrosion. See: Actions You Can Take to Reduce Lead in Drinking Water, EPA810-F-93001, June 1993).
