Wastewater Treatment Operator Certification Practice Test

Which law regulates wastewater discharge to receiving water?

1. Wastewater Act

2. Clean Water Act

3. National Discharge Act

4. Federal Effluent Act

The correct answer is: Clean Water Act

The Clean Water Act is the primary federal law in the United States that regulates the discharge of pollutants into the waters of the country, including rivers, lakes, and coastal waters. This act establishes the framework for regulating the quality of surface waters and aims to ensure that water bodies meet appropriate quality standards for various uses such as recreation, drinking, and habitat for wildlife. Under the Clean Water Act, the Environmental Protection Agency (EPA) has the authority to set water quality standards and enforce regulations for the discharge of pollutants. It requires facilities that discharge wastewater to obtain a National Pollutant Discharge Elimination System (NPDES) permit, ensuring that discharges do not harm aquatic ecosystems or public health. The act emphasizes the importance of maintaining clean and safe water resources for the community and the environment, making it a cornerstone of water pollution control efforts in the U.S. The other options mentioned either do not exist under those names or are not specifically responsible for the regulation of wastewater discharges to receiving waters in the same comprehensive way that the Clean Water Act is.
