A cross connection is?

A cross connection is?

• A. Cast Iron pipe connected to concrete pipe
• B. Steel pipe connected to asbestos pipe
• C. Potable (Drinkable) water pipe connected to a supply of questionable origin
• D. Lateral line connected to an interceptor

Answer: (C)

A cross connection refers specifically to an undesirable connection between a potable water supply and a system that contains non-potable water or contaminants. This situation can lead to the contamination of the drinking water supply if backflow occurs. Therefore, the correct answer identifies a scenario where a drinkable water pipe is linked to a supply that may be questionable, meaning there is a risk of contamination. The other options involve various types of pipe connections that do not directly relate to the concept of cross connections or the risk of contamination of potable water. For example, connections between different materials, such as cast iron to concrete or steel to asbestos, focus more on material compatibility and structural integrity rather than the health risks presented by mixing potable and non-potable water sources. Similarly, a lateral line connected to an interceptor pertains to wastewater management and does not address the critical issue of potential drinking water contamination.
