Which 1975 act is focused on ensuring safe drinking water standards?

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

Answer: (A)

The main idea being tested is which law sets nationwide standards to protect the quality of drinking water delivered to the public. The act that does this is the Safe Drinking Water Act, which established national health-based standards for drinking water and the framework for oversight of public water systems. It was enacted in the early 1970s and implemented in the following years to ensure tap water is safe for consumption.

From the options, the one that most closely matches the concept of protecting drinking water quality is the entry that references drinking water, but the official title is Safe Drinking Water Act rather than the wording shown. The Clean Water Act addresses the protection of surface waters and pollution control for discharges, not the standards for drinking water itself. The Water Quality Act is an earlier, broader step in water quality regulation but not specifically focused on drinking-water standards. Primary Sewage Treatment is not a formal act focused on drinking-water safety.

So, the correct idea is Safe Drinking Water Act, which is the law that focuses on safe drinking water standards. The wording in the option that resembles that idea isn’t the official title, which is why the precise correct answer is the act dedicated to drinking-water safety.
