What does "cross-connection" refer to?

A cross-connection specifically refers to a physical link between potable (drinkable) water and non-potable (non-drinkable) sources. This type of connection is critical to understand because it poses a potential risk for contamination of the drinking water supply if non-potable water backs up into the potable system. Cross-connections can occur in various scenarios, such as garden hoses connected to chemical sprayers or irrigation systems that are improperly designed.

Using the correct terminology helps illustrate the importance of maintaining system integrity for public health, as cross-connections must be managed and mitigated to prevent the hazards they pose. Recognizing the implications of cross-connections is vital for water distribution professionals, as they work to ensure safe and clean drinking water for the community.
