What must be documented when there is a health-related violation in a water system?

When a health-related violation occurs in a water system, it is crucial to document public notification details. This is essential because when violations pose a risk to public health, the water system must communicate effectively with its customers regarding the nature of the violation, the potential health risks involved, and the steps being taken to rectify the situation. This documentation ensures that all stakeholders, including consumers and regulatory bodies, are informed, which is vital for maintaining trust and compliance with public health standards. Proper notification allows affected individuals to take necessary precautions and reflects the system's commitment to public health and safety.
