Is the statement 'The gravel pack is fine gravel placed around the screen to reduce pumping bacteria' true?

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (B)

The gravel pack around a well screen is meant to create a stable, coarse filtration zone that keeps formation fines and sand from entering the well and helps protect the screen from clogging, not to reduce bacteria. Bacterial control comes from proper well construction, sealing, disinfection, and treatment of the water, not from the gravel pack. So the statement is false.
