What is the EPA's lead action level for drinking water?

The Environmental Protection Agency (EPA) has established a lead action level of 0.015 milligrams per liter (mg/L) for drinking water. This standard is significant because it helps ensure public health by reducing lead exposure, which can have serious health consequences, particularly for young children and pregnant women. The lead action level is a threshold that triggers specific actions to be taken by water suppliers if lead levels exceed this amount.

When lead concentrations are found to be higher than the action level, utilities must take steps such as corrosion control, public education, and additional lead monitoring to reduce lead levels in drinking water. The focus on such a precise action level reflects the critical nature of preventing lead contamination, which can originate from lead pipes, fixtures, and solder in plumbing systems. Understanding this standard is essential for sanitation professionals as they work to ensure safe drinking water for the public.
