What federal regulation requires that samples from customers' taps be analyzed for the presence of lead and copper?

• A. Safe Drinking Water Act
• B. Clean Water Act
• C. Lead and Copper Rule
• D. Water Quality Improvement Act

Answer: (C)

The Lead and Copper Rule is a specific regulation established under the Safe Drinking Water Act that mandates utilities to conduct testing for lead and copper levels in drinking water, specifically in samples taken from customers' taps. This rule aims to minimize the risks of lead and copper exposure from drinking water supplies, particularly focusing on preventing corrosion of plumbing materials that can leach these metals into the water.

The significance of the Lead and Copper Rule lies in its targeted approach to water safety and public health. It requires utilities to monitor their water systems for these contaminants, to inform consumers about lead and copper levels, and to take action when lead or copper levels exceed the established action levels. This is vital for protecting vulnerable populations, such as children, whose health can be adversely affected by lead exposure. Therefore, this regulation plays a crucial role in ensuring that safe drinking water standards are maintained, thereby contributing to overall public health initiatives.
