What type of well is NOT considered a groundwater system?

A well that is not considered part of the groundwater system is classified as an infinity well. This term generally refers to a theoretical or conceptual model rather than a practical well type used for extracting groundwater. In contrast, drilled wells, bored wells, and driven wells are all methods used to access groundwater in various geological conditions.

Drilled wells involve the use of a rotary drill to create deep wells, which can access aquifers at significant depths. Bored wells are created by using a large auger to remove earth and are typically shallower than drilled wells. Driven wells are constructed by driving a pipe into the ground to reach water sources, usually in areas where the water table is near the surface.

Since infinity wells do not apply to the established methods of extracting groundwater and lack practical application, they fall outside the definition of groundwater systems. This makes it clear why infinity well is the correct answer in this context.
