<human>: I've heard a lot about the dangers of lead in drinking water. Is this true?
<bot>: Yes, it is true that lead can be found in drinking water and can be harmful to health if consumed in high levels. Lead can leach from pipes, fixtures, and solder used to connect pipes together, as well as from brass faucets, valves, and other metal components. It can also enter drinking water through corrosion of plumbing materials or through old lead service lines connecting homes to the main water supply.
