What is a potential consequence of backflow into a potable water system?

  1. Increased flow pressure

  2. Water contamination

  3. Clogging of pipes

  4. Improved water quality

The correct answer is: Water contamination

The potential consequence of backflow into a potable water system is water contamination. When backflow occurs, it can allow non-potable water, which may contain harmful pathogens, chemicals, or other pollutants, to flow back into the drinking water supply. This creates a significant health risk for consumers, as contaminated water can lead to disease outbreaks and other serious health issues. In a potable water system, maintaining the integrity and safety of the water supply is critical. Backflow events compromise this safety by introducing potentially hazardous substances that were not present in the original drinking water. Recognizing the importance of backflow prevention measures is essential to protect public health and ensure a reliable source of clean water.
