Monthly disinfection of holding tanks and water distribution loops is aimed at controlling which of the following?

Monthly disinfection of holding tanks and water distribution loops is primarily aimed at controlling bacterial contamination. This process is crucial in maintaining safe and potable water for consumers, as bacterial contamination can lead to serious health risks and waterborne diseases. Regular disinfection ensures that any potentially harmful bacteria present in the water systems are effectively eliminated, thereby reducing the risk of outbreaks of infections.

While other factors such as algae growth might be relevant to water quality, the main purpose of routine disinfection specifically targets bacterial organisms which can thrive in these environments. This proactive strategy is essential for ensuring that water meets safety standards and maintains public health.
