What is the lead action level set at?

The lead action level is set at 0.015 mg/L, which is critical for ensuring public health and safety in drinking water. This value is established under the Lead and Copper Rule, a regulation aimed at reducing lead and copper levels in drinking water, particularly to protect vulnerable populations such as children and pregnant women.

When the concentration of lead in drinking water exceeds this action level, water systems are required to take specific actions, including monitoring, public education, and potential corrosion control measures. The significance of this action level lies in its role in preventing lead exposure, which can lead to serious health issues, including developmental problems in children and cardiovascular effects in adults.

Other values provided do not reflect the established action level for lead in drinking water. Understanding this action level is essential for water treatment professionals, as it guides regulatory compliance and public health protection efforts.
