The monthly bacteriological sample should be marked with which label?

• A. Construction
• B. Approved
• C. Rejected
• D. Pending

Answer: (A)

Labeling the monthly bacteriological sample as Construction is about identifying the context of the collection. When a site or portion of the distribution system is under construction, water quality can be affected by temporary changes, contamination risks, or different sampling points. Marking the sample Construction ensures it’s tracked separately from routine samples and handled with the appropriate procedures, so the lab and operators interpret the results correctly and can trace any issues back to the construction activity. Labels that indicate Approved, Rejected, or Pending refer to the test result status, not the sampling context, so they aren’t as helpful for distinguishing samples gathered during construction.
