in Drinking Water
Lead is a toxic metal that was commonly used in plumbing, paint, and gasoline. It can enter drinking water through corroding pipes, faucets, and fixtures, especially in homes built before 1986.
15 ppb (Action Level)
This is the maximum contaminant level (MCL) that water systems must meet by law.
0 ppb (no safe level)
There is no safe level of lead exposure, especially for children.
Exposure to lead in drinking water can cause various health problems:
