What is the objective of the Clean Water Act?

• A. Set maximum permissible amounts of water pollutants that can be discharged into waterways
• B. Increase water use
• C. Regulate groundwater withdrawals
• D. Protect wetlands only

Answer: (A)

The key idea is controlling pollution by setting limits on what can be discharged into waters. The Clean Water Act establishes maximum allowable amounts of pollutants that can be released from a point source into waterways, and it enforces these limits through permits and measurable effluent standards. This framework is designed to protect water quality and aquatic life by ensuring dischargers treat and reduce pollutants to meet those set limits.

Other options don’t capture the main purpose: increasing water use isn’t the aim, groundwater withdrawals are managed under different laws and programs, and while protecting wetlands is important, it isn’t the sole objective of the act—the focus is on regulating discharges into surface waters and maintaining overall water quality.
