Introduction to Groundwater Monitoring
questions and answers graded A+
Define aquifer - correct answer ✔✔saturated geologic unit that can store transmit and yield
groundwater in sufficient quantity to constitute a usable supply
What is the upper boundary in an unconfined aquifer - correct answer ✔✔water table
What is the lower boundary in an unconfined aquifer - correct answer ✔✔impervious layer
What is the potentiometric surface - correct answer ✔✔the height the water could potentially
rise to if the confined aquifer is tapped by a well
When do flowing artesian conditions occur - correct answer ✔✔when the potentiometric
surface is above the top of the well casing
