Regulations and Compliance Practice Questions for Level 1 · Entry

2 free sample questions on regulations and compliance for the Level 1 · Entry wastewater treatment operator exam. Try each one, then open the answer to check your work.

  1. Question 1

    Before submittal, a draft DMR value differs from the laboratory bench sheet. The QA-approved laboratory report agrees with the bench sheet. What should the operator do?

    1. Update the DMR record
    2. Submit the draft entry
    3. Average both entries
    4. Replace the lab record
    Show the answer

    Answer: A. Update the DMR record

    The bench sheet and QA-approved report agree, so the draft DMR record should be updated before submittal. Submitting the draft error, averaging unlike entries, or changing the laboratory record would make the report inaccurate.

  2. Question 2

    A permit-required weekly TSS sample was missed, and no valid substitute sample exists. The monthly report is due. What should the operator do?

    1. Report the missing data
    2. Use the last valid sample result
    3. Estimate using turbidity data
    4. Average the nearby valid results
    Show the answer

    Answer: A. Report the missing data

    The operator should report the missing monitoring data as required and document why no valid weekly TSS result exists. Reusing the last result, estimating from turbidity, or averaging nearby results would create a value that was not measured for the missed sample.
