What term describes a physical connection that allows non-potable water to enter potable water systems?

The term that describes a physical connection allowing non-potable water to enter potable water systems is a cross connection. This connection can create a pathway for contaminants from non-potable sources, such as irrigation systems or industrial processes, to flow into the drinking water supply, which poses a significant health risk.

Recognizing cross connections is crucial for maintaining water quality and preventing contamination. Effective backflow prevention devices are often installed to protect the integrity of potable water systems from any potential hazards associated with cross connections. Understanding this concept is vital for operators, as it ensures they can implement appropriate measures to safeguard public health and comply with regulatory standards.
