What does the term "cross-connection" refer to in water systems?

• A. A connection that enhances water pressure
• B. A link between potable water and non-potable sources
• C. A type of water filtration system
• D. A method of water disinfection

Answer: (B)

The term "cross-connection" specifically refers to a link between potable (drinkable) water and non-potable sources. This concept is critical in understanding water safety and preventing contamination. A cross-connection poses a significant risk because if the non-potable source becomes pressurized, it could lead to the backflow of contaminants into the potable water supply. This situation can occur in various scenarios, such as improper plumbing installations or the use of garden hoses submerged in contaminated water sources. Recognizing cross-connections helps water systems implement necessary safeguards, such as backflow prevention devices, to maintain water quality and protect public health. Understanding this term is essential for water system operators and public health officials, as it directly relates to ensuring safe drinking water and effective management of water resources.
