After a well is drilled, contractors must provide a DEC ___________ report to the well owner.

• A. Drilling log
• B. Water quality
• C. Well completion
• D. Site assessment

Answer: (C)

Documentation after a well is drilled that verifies proper construction and records key details is what regulators require to be reported to the owner. The well completion report communicates the final construction specifics—such as depth, casing and screen details, grout placement, pump setting, and any tests or observations gathered during completion—and provides a formal record that the project met the required standards. This helps the owner plan maintenance and gives the regulatory agency a clear record of how the well was built.

Drilling log records activity during drilling itself, not the final completion details. Water quality information is typically gathered through separate testing and reporting, not the completion documentation. A site assessment is done before drilling to evaluate conditions and feasibility, not after completion.
