What is the population threshold for a public water system classification?

The classification of a public water system is determined by specific thresholds related to population size and the number of service connections. For a system to be classified as a public water system, it must serve at least 25 people or have a minimum of 15 service connections. This classification is critical for regulatory purposes, as public water systems are subject to various health and safety standards to ensure the water provided is safe for consumption.

Being aware of these thresholds is essential for those working in environmental health, as it helps in identifying which systems fall under federal or state regulations for public health protection. Understanding the classification allows health specialists to ensure compliance with water quality standards, monitor safety practices, and address any potential public health risks associated with water supply.
