Final answer:

A cross-connection is a link between the public water supply and a source of contamination, posing significant health risks. It's crucial to understand these connections to protect drinking water safety. Preventing cross-connections is essential to avoid waterborne diseases.


Explanation:

Understanding Cross-Connections


A cross-connection is a physical link between the public water supply and a source of contamination. This may occur when pipes carrying safe, potable water are connected to systems that can introduce contaminated water, jeopardizing the safety of the drinking water supply. This situation can happen through backflow, where contaminated water from a non-potable system can seep back into the potable water supply.


The Importance of Preventing Cross-Connections


Preventing cross-connections is crucial for public health, as it can prevent the possibility of waterborne diseases. For example, if a garden hose is submerged in a pool of contaminated water and there is a drop in water pressure, the contaminated water can be pulled back into the public water mains, posing health risks to community members.
