Which act established safety standards for drinking water and is distinct from environmental discharge controls?

• A. Water Quality Act
• B. Primary Sewage Treatment
• C. Clean Drinking Water Act
• D. Harmful Algal Blooms

Answer: (C)

The main idea here is that protecting drinking water focuses on setting enforceable safety standards for the water that people actually drink. An act like this creates maximum contaminant levels, treatment requirements, and monitoring rules for public water systems so consumers receive water that meets health-based standards. This is separate from environmental discharge controls, which govern what pollutants can be released into waterways from sources like factories or wastewater plants and how those discharges are treated before entering rivers or lakes. The option named “Clean Drinking Water Act” is addressing drinking-water safety directly, rather than regulating discharges into the environment. The other options either refer to processes or programs about water quality in a broader sense, or to wastewater treatment, which are not about establishing drinking-water safety standards for consumers.
