ASBOG Practice of Geology (PG) VIP Exam
ASBOG — The ASBOG (Association of State Boards of Geology) administers two national licensure exams — the Fundamentals of Geology (FG) and the Practice of Geology (PG) — each consisting of 100 multiple-choice questions over 4 hours, with a passing score typically set near 70% scaled score, used by most U.S. states to license Professional Geologists.

Question 1 of 29👑 VIP
A hydrogeologist conducts a constant-rate pumping test in an unconfined sand aquifer. After 60 minutes of pumping at 15 gallons per minute, the drawdown at an observation well 50 feet away is 3.2 feet, and the hydraulic gradient between the pumping well and observation well is 0.064. The saturated thickness of the aquifer prior to pumping is 40 feet. Using the Dupuit assumption, what is the most appropriate conclusion about delayed yield in this aquifer? A. Delayed yield is negligible because the aquifer is fully saturated throughout the test. B. Delayed yield is likely occurring, as evidenced by a flattening of the time-drawdown curve before typical Theis behavior resumes. C. Delayed yield only occurs in confined aquifers and is therefore irrelevant here. D. The 60-minute test duration is sufficient to eliminate delayed yield effects entirely.
