What is the Environmental Protection Agency's (EPA) action level for lead in drinking water?

The Environmental Protection Agency's action level for lead in drinking water is established at 15 parts per billion (ppb). This threshold is significant as it serves as a guideline for water systems to take necessary measures if lead levels exceed this concentration. The EPA's regulation aims to protect public health, especially in vulnerable populations such as children and pregnant women, who are at greater risk for lead exposure and its associated health effects.

When lead levels are found to be above this action level, the water system is required to take corrective actions, which may include notifying consumers, optimizing corrosion control treatment, and replacing lead service lines. This proactive approach helps to mitigate the potential risks associated with lead in drinking water and ensures safer water for all consumers.
