What is the primary purpose of a cross-connection control program?

The primary purpose of a cross-connection control program is to prevent contamination of the public water supply. Cross-connections occur when there is a direct physical link between the potable water supply and a source of contamination, which can lead to backflow and the potential introduction of harmful substances into the drinking water system. Implementing a cross-connection control program involves identifying, monitoring, and managing these connections to safeguard public health by ensuring that the water supply remains safe and uncontaminated.

Programs typically include regular testing of backflow prevention devices, educating the public about potential hazards, and setting regulations that restrict improper connections. This proactive approach is essential for maintaining the integrity and safety of the water supply, thereby protecting the community from potential waterborne illnesses and other health risks associated with contaminated water.
