Which term describes enforceable standards for drinking water that can be violated with penalties?

• A. The Secondary Drinking Water Standards
• B. The Primary Drinking Water Regulations
• C. The Safe Drinking Water Act amendments
• D. The Clean Water Act provisions

Answer: (B)

Primary Drinking Water Regulations are the enforceable standards for drinking water that can be violated with penalties. They set legally binding limits on contaminants in public water systems, including maximum contaminant levels and required treatment techniques. When a system fails to meet these standards, agencies like the EPA or state authorities can impose penalties and require corrective actions. In contrast, Secondary Drinking Water Standards are guidelines for taste, odor, and appearance that are not enforceable and carry no penalties. Amendments to the Safe Drinking Water Act change the law itself rather than a specific standard, and provisions of the Clean Water Act address discharges and protection of surface waters rather than drinking-water quality standards.
