What best describes data integrity expectations in wastewater laboratory reporting?

• A. Data must be accurate and complete.
• B. Data must be accurate, traceable, complete, and auditable; maintain audit trails.
• C. Data integrity requires only accuracy.
• D. Data integrity is not regulated in lab reporting.

Answer: (B)

In wastewater laboratory reporting, data integrity means information is trustworthy across its entire lifecycle: it must be accurate, complete, traceable, and auditable, with an ongoing audit trail. Accuracy ensures the results reflect the true measurement, while completeness means no essential data or metadata are missing. Traceability connects every data point to its source—the instrument, method, date and time, and the person who performed the work—so you can follow how a result was produced. Auditable data have a verifiable history of how data were created, changed, or deleted, including who made the change and when. Maintaining audit trails is essential so investigators can reconstruct events and verify authenticity. Together, these elements align with regulatory and QA/QC expectations for reliable, defensible reporting.
