Final answer:

A cross-connection is a link between safe and contaminated water, representing a risk for public health. Such connections can allow polluted water to contaminate clean water supplies. It is vital to prevent these connections to maintain water purity and safety.


Explanation:

Understanding Cross-Connections


A cross-connection is an unwanted link between two different systems that can lead to contamination. Specifically, it refers to a connection between safe and contaminated water, which poses a significant health risk as it can allow polluted water to enter a clean water supply.


For example, if a hose used for watering plants is submerged in a contaminated bucket, and the water pressure drops, it's possible for dirty water to flow back into the clean supply. This relationship illustrates why maintaining an appropriate separation between potable and non-potable systems is crucial.


Importance of Preventing Cross-Connections



  • Protects public health by preventing waterborne diseases.

  • Preserves the integrity of municipal water supply systems.

  • Ensures compliance with water safety regulations.
