Under the Safe Drinking Water Act definition, a public water system is defined as having which combination?

• A. 15 service connections or regularly serves 25 people
• B. 25 service connections or regularly serves 15 people
• C. 15 service connections or regularly serves 15 people
• D. 25 service connections or regularly serves 25 people

Answer: (A)

Under the Safe Drinking Water Act, a public water system is defined by meeting one of two size criteria: a minimum number of service connections or a minimum number of people served regularly. The correct option mirrors this structure exactly, using an "or" to connect the two independent thresholds: if a system reaches either the service-connection threshold or the daily-people-served threshold, it is considered a public water system. This distinction matters because the regulation applies to those systems that reach at least one of these size benchmarks, triggering federal oversight and compliance requirements. The other choices misstate the thresholds or switch the relationship from "or" to "and" or otherwise alter the criteria, which is why they don't align with the definition.
