- A test to determine hydrologic properties of the aquifer involving the withdrawal of measured quantities of water from or addition of water to a well and the measurement of resulting changes in head in the aquifer both during and after the period of discharge or additions .

Aquifer test — An aquifer test (or a pumping test) is conducted to evaluate an aquifer by stimulating the aquifer through constant pumping, and observing the aquifer s response (drawdown) in observation wells. Aquifer testing is a common tool that… … Wikipedia
Aquifer — Typical aquifer cross section An aquifer is a wet underground layer of water bearing permeable rock or unconsolidated materials (gravel, sand, or silt) from which groundwater can be usefully extracted using a water well. The study of water flow… … Wikipedia
Slug test — A slug test is a particular type of aquifer test where water is quickly added or removed from a groundwater well, and the change in hydraulic head is monitored through time, to determine the near well aquifer characteristics. It is a method used… … Wikipedia
