Define "cross-connection" in the context of water supply.

• A. A connection that allows backflow of non-potable water
• B. A link between two potable water sources
• C. A system that monitors water purity
• D. A network of pipes in a distribution system

Answer: (A)

A cross-connection refers to a point in the water supply system where a non-potable water source can potentially mix with the potable (drinkable) water supply. This is a critical concern in water quality management, as such connections pose health risks if contaminants are introduced into the clean water system. Backflow can occur in these situations, leading to situations where harmful substances can enter the drinking water supply, which is why preventing cross-connections is a fundamental aspect of water distribution safety practices. This concept is crucial for water operators to understand, as it underscores the importance of proper plumbing practices and backflow prevention measures to ensure the safety of public water supplies.
