What is the action level for lead in drinking water?

The action level for lead in drinking water is established at 0.015 mg/L. This threshold is set by regulatory bodies such as the Environmental Protection Agency (EPA) to safeguard public health. Practically, this means that if lead levels in a water system exceed this action level, the water system is required to take specific actions. These may include initiating corrosion control treatment, replacing lead service lines, or informing the public about the potential health risks associated with lead exposure.

Lead is a harmful contaminant, especially for children and pregnant women, as it can lead to serious health issues, including developmental delays and cognitive impairments. Therefore, it is crucial for water operators and systems to monitor lead levels closely and implement strategies to keep them below the action level.

While other figures may exist for various contaminants, the benchmark of 0.015 mg/L for lead has been recognized and enforced to protect public health.
