When addressing a cross connection contamination incident, it is crucial for a qualified tester to take comprehensive action to effectively manage the situation. The correct response involves not only identifying and isolating the source of contamination but also notifying both the customer and the health department. Identifying and isolating the source is essential as it prevents further contamination and protects public health. By isolating the source, you can ensure that no additional water supplies or systems are affected, mitigating the risk of widespread contamination. Notifying the customer is vital for them to understand the potential risks and the steps being taken to rectify the situation. However, informing the health department is equally important. In many jurisdictions, public health agencies need to be made aware of such incidents to assess the impact on the broader community and coordinate appropriate public health responses. Overall, this comprehensive approach highlights the importance of not only managing the immediate fallout of contamination but also engaging with relevant authorities to ensure public safety and compliance with regulations.
