What should be done after measuring chlorine levels post GAC filter 1?

After measuring chlorine levels post GAC filter 1, the most appropriate action is to report to the medical officer. This is crucial because chlorine levels are directly related to water safety and treatment efficacy. If the chlorine levels are outside the acceptable range, it might indicate a malfunction or issue with the filtration system, which could impact the safety of the water supply. Reporting to the medical officer ensures that the situation is assessed by a qualified individual who can take necessary actions to ensure public health and safety.

While measuring again after tank 1 may seem like a logical step, it does not address potential immediate risks associated with the water being treated or supplied. Similarly, resuming treatment immediately without confirming the safety of the water could lead to significant health hazards. Decreasing the flow rate might be a suitable response in specific scenarios, but it does not take precedence over the need to report potentially hazardous conditions to a medical officer who is trained to handle such matters. In critical situations involving water treatment, prioritizing communication with health authorities is essential for ensuring compliance with safety protocols and regulations.
