What is the maximum allowable lead concentration in drinking water as per the EPA?

The maximum allowable lead concentration in drinking water, as established by the Environmental Protection Agency (EPA), is 0.015 mg/L. This limit is set to protect public health, particularly for vulnerable populations such as children and pregnant women, who are more susceptible to the harmful effects of lead exposure. The EPA's Lead and Copper Rule is designed to minimize lead and copper levels in drinking water to safeguard consumers. Lead can enter drinking water primarily through corrosion of lead-containing plumbing materials, so maintaining a low concentration is crucial for ensuring safe drinking water.
