What is the threshold limit for lead concentration in drinking water?

The threshold limit for lead concentration in drinking water is established at 0.015 mg/L. This limit is based on guidelines from the U.S. Environmental Protection Agency (EPA), which aim to protect public health, especially for vulnerable populations such as children and pregnant women. Lead is a toxic metal that can cause serious health problems, including developmental issues in children and various health complications in adults.

Setting the limit at 0.015 mg/L is intended to minimize the risk of lead exposure from drinking water, while also balancing the need for practical and achievable water quality standards for water suppliers. The regulations reflect scientific research on the health impacts of lead and help ensure that drinking water remains safe for consumption. This threshold limit is crucial for maintaining public health and preventing lead-related health issues in the community.
