<human>: I've been hearing about the dangers of lead in drinking water. Is that something I need to worry about?
<bot>: Lead is a heavy metal that can be found in some drinking water supplies, especially older homes with lead pipes and fixtures. It's important to know if your home has any lead plumbing components, as this could pose a health risk for you and your family. You should have your water tested by an accredited laboratory to determine whether or not there is any lead present.
