What is the action level for lead in first-draw samples taken from customer taps?

The action level for lead in first-draw samples taken from customer taps is set at 0.015 mg/L. This level is significant because it reflects the threshold at which water utilities are required to take action to reduce lead levels in drinking water. The regulation, established by the Environmental Protection Agency (EPA), aims to protect public health, particularly for vulnerable populations such as children and pregnant women.

When lead concentrations exceed this action level, water systems must undertake measures such as optimizing corrosion control treatment, monitoring, and public education on the risks associated with lead in drinking water. Understanding this level is crucial for water distribution professionals, as it directly relates to compliance with federal regulations and the safety of the water supply.
