Required Lab Test Report Information requires data to be reported under whose direct supervision?

• A. Chapter 252 requires reporting of data by environmental laboratories to be done under the direct supervision of a laboratory supervisor.
• B. All data must be reported within 24 hours.
• C. Laboratories publish their data in public registry.
• D. Results must be archived for 10 years.

Answer: (A)

The key idea is that data reported by environmental laboratories must be under the direct supervision of a laboratory supervisor. This requirement exists to ensure the integrity and reliability of the test results: a supervisor is responsible for confirming that the testing was conducted correctly, that personnel are properly trained, and that appropriate QA/QC checks are performed and documented. The supervisor reviews methods, validates calculations, signs off on final results, and ensures records are complete and compliant with approved procedures.

Timeliness (reporting within 24 hours), publishing data in a public registry, or archiving results for a set number of years are separate requirements that govern how information is handled or shared, not who supervises the reporting.
