ASBOG FG PG case studies
ASBOG FG PG · Put your knowledge to work in context.
ASBOG - the National Association of State Boards of Geology - is a national association of state geology licensing boards whose stated mission is "to promote the competent practice of geology by delivering rigorous licensure examinations, expanding license availability and mobility, and fostering academic training that protects public health, safety, and welfare." The Association administers the geology licensure examinations used by its member boards in regulated states, commonly referred to as the Fundamentals of Geology (FG) and Practice of Geology (PG) examinations. The FG exam is generally the entry-level examination for candidates completing or recently completing a geoscience degree; the PG exam is the practice-level examination tied to professional experience requirements set by the individual state board. The ASBOG FG PG case studies are 5 cases and about 4,303 words.
1Siting a Second Municipal Well: Interference Drawdown vs Pump Setting
A municipal wellfield pumps from a sand aquifer with transmissivity 850 m²/d and an estimated storativity of 4×10⁻⁴. Well A, screened across the full 18 m saturated thickness, has produced 2,500 m³/d for years.
