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 critical for protecting public health, particularly for vulnerable populations such as children and pregnant women, as exposure to lead can have serious health implications. When water systems exceed this level, they are required to take action to mitigate lead contamination, which may include steps like optimizing corrosion control or replacing lead service lines.

By defining this specific action level, public health authorities can ensure that water systems monitor and reduce lead levels effectively to minimize health risks associated with lead exposure. This standard is supported by extensive research linking lead in drinking water to various health issues, reinforcing the importance of maintaining water quality within this limit.
