According to U.S. law, what is one act that grants authority for pollution control measures?

The Clean Water Act of 1972 is a pivotal piece of legislation in U.S. environmental law that aims to restore and maintain the integrity of the nation’s waters. It grants the federal government significant authority to regulate discharges of pollutants into navigable waters, thus establishing a comprehensive framework for water quality standards and point source pollution control. Through this act, the Environmental Protection Agency (EPA) is empowered to set limits on pollutants that can be released into water bodies, effectively providing a mechanism for enforcement and accountability in pollution control measures. This legislation plays a crucial role in protecting aquatic ecosystems and ensuring safe water for public consumption and recreation.

While other acts listed in the question also address pollution control—such as the Clean Air Act, which focuses on air quality, and the Safe Drinking Water Act, which pertains to drinking water standards—they are specific to their respective domains. The Clean Water Act specifically targets water pollution, making it the most appropriate answer concerning authority granted for pollution control measures related to water bodies.
