What is the maximum allowable lead concentration in drinking water set by the EPA?

The maximum allowable lead concentration in drinking water set by the Environmental Protection Agency (EPA) is 0.015 mg/L. This standard is established to protect public health, particularly to avoid the harmful effects of lead exposure, which can have significant health implications, especially for children. Elevated lead levels can lead to developmental issues and other serious health concerns.

The specific limit reflects extensive research and risk assessments done by the EPA, taking into account the potential for lead exposure from plumbing and other sources. By setting this limit, the EPA aims to reduce lead levels in drinking water to a point that is considered safe for human consumption and minimizes any associated health risks.
