The act that governs wastewater standards for industry is often cited as which of the following?

• A. Water Quality Act
• B. Clean Waters Act
• C. Clean Air Act
• D. CERCLA

Answer: (B)

Industrial wastewater standards come from the Clean Water Act. This federal law focuses on protecting the nation’s waterways by regulating what pollutants industries can discharge into rivers, lakes, and coastal waters. It uses the NPDES permit program to set specific effluent limits that facilities must meet, requiring treatment to bring discharges within those limits. The Clean Water Act also establishes water quality standards to maintain the usability of water bodies. Other acts address different areas: the Clean Air Act regulates air pollution, CERCLA concentrates on cleaning up hazardous waste sites, and the Water Quality Act is an older framework that preceded the comprehensive controls of the Clean Water Act. So the Clean Water Act is the primary reference for industrial wastewater standards.
