How does lead get into my drinking water?

Lead is rarely found naturally in our source water or in the treated water flowing through the distribution system. More commonly, lead dissolves into water over time through corrosion—a chemical reaction between water and your plumbing. Lead can dissolve into water from pipes, solder, fixtures, faucets (brass) and fittings. The amount of lead in your water depends on the types and amounts of minerals in the water, how long the water stays in the pipes, the water’s alkalinity, corrosivity, pH and water temperature.
