What can be one result of improperly managed cross-connections?

One result of improperly managed cross-connections is an increased risk of waterborne diseases. Cross-connections occur when there is a direct link between potable (drinking) water and non-potable sources, which can allow contaminants to enter the drinking water supply. When these cross-connections are not managed properly, pollutants, chemicals, or pathogens from non-potable sources can flow back into the potable water system, leading to contamination. This contamination poses a significant health risk, as it can result in the spread of diseases transmitted through contaminated water, such as cholera or giardia.

By ensuring that cross-connections are properly managed and protected against potential backflow, water utilities can maintain the safety and integrity of the drinking water supply, thus significantly reducing the risk of waterborne illnesses.
