How could lead get into the drinking water?

Lead is a common and naturally occurring metal that is found throughout the environment. However, it is rare to find lead in surface water supplies such as lakes and rivers. If lead is detected in drinking water, it is primarily due to of corrosion in lead pipes that connect some older homes (pre-1986) to the water system and/or household plumbing such as brass or chrome plated brass faucets that contain lead.
