Monthly Operational Reports (MORs) are required to be kept for what duration?

Monthly Operational Reports (MORs) are critical documents that help ensure the safe and effective operation of drinking water treatment facilities. The requirement to retain these reports for a specific duration is primarily tied to regulatory compliance and the ability to verify operational performance over time.

In this case, retaining Monthly Operational Reports for 10 years allows for a comprehensive review of long-term operational trends and performance. This duration ensures that operators can track any changes in water quality, evaluate the effectiveness of treatment processes, and ensure compliance with applicable regulations over an extended period. It also assists in identifying recurring issues, helping to demonstrate compliance during audits or inspections.

Retention for 10 years strikes a balance between having sufficient historical data available for review, while also aligning with commonly established practices in the water treatment industry. Regulatory agencies often set such timeframes to facilitate both operational transparency and public health assurances.
