Question

artesian wells are a unique feature associated with confined aquifers. these wells tap into groundwater that is under pressure. what will happen when such a well is drilled? the water will rise to the surface or even flow continuously due to the pressure. the well will only produce a small amount of water, making it unreliable. the water table will rise higher and higher leading to flooding. the quality of the water will become poor, requiring extensive treatment before use.

Explanation:

Artesian wells tap into confined aquifers with groundwater under pressure. When drilled, the pressure forces the water to rise to the surface or flow continuously. The other options are incorrect: the well isn't unreliable (it's from a pressurized aquifer), drilling an artesian well doesn't cause the water table to flood (water table is for unconfined aquifers), and pressure - related drilling doesn't inherently reduce water quality.

Answer:

The water will rise to the surface or even flow continuously due to the pressure.
