What is the Maximum Contaminant Level (MCL) for Lead (Pb) in drinking water?

• A. 0.005 mg/L
• B. 0.015 mg/L
• C. 0.025 mg/L
• D. 0.035 mg/L

Answer: (B)

The Maximum Contaminant Level (MCL) for lead (Pb) in drinking water is established at 0.015 mg/L. This standard is set by regulatory bodies like the Environmental Protection Agency (EPA) to protect public health by minimizing lead exposure through drinking water. Lead is a toxic metal that can have serious health consequences, particularly for pregnant women and young children, including developmental effects and neurological harm. By setting the MCL at this level, it is aimed at significantly reducing the risk of lead exposure from drinking water sources, while also accounting for the feasibility of treatment and detection methods available for water systems. The purpose of the MCL is to ensure that drinking water is safe and to guide water utilities in managing lead in their distribution systems effectively.
