What is the action level for lead in drinking water?

The action level for lead in drinking water is set at 0.015 mg/L. This standard is established by the Environmental Protection Agency (EPA) to protect public health, particularly vulnerable populations such as children and pregnant women, from the harmful effects of lead exposure. If the lead concentration in drinking water exceeds this level, water systems must take specific actions to reduce lead levels, including notifying the public and implementing corrosion control measures. This action level is critical for ensuring safe drinking water and aligns with regulatory requirements designed to minimize lead contamination in water supplies.
