The number of monthly distribution system chlorine residual samples required is:

The number of monthly distribution system chlorine residual samples required is:

• A. Fixed for all systems
• B. Based on population
• C. Determined by type of water source
• D. Decided by state regulations

Answer: (B)

The requirement for monthly distribution system chlorine residual samples is based on population. The rationale behind this is that larger populations typically require a more robust monitoring system to ensure safe drinking water standards are met. A greater number of samples can help detect variations in chlorine residual levels and potential contamination issues, ensuring that all consumers receive water that is safe and within regulatory limits. Smaller systems with fewer connections may have less stringent sampling requirements because they present a lower risk of widespread contamination. Thus, the number of required samples directly correlates with the population served, which ensures that each system is appropriately monitored based on its specific needs. This approach allows for a more tailored and effective regulatory framework that takes into account the varying risks associated with different system sizes.
