What are driven and jetted wells characterized by?

Driven and jetted wells are specifically characterized by the use of a well point system, which typically includes a filtered screen. This screen allows water to enter the well while preventing sediments and larger particles from contaminating the water supply. In driven wells, this system is physically pushed into the ground through mechanical force, while jetted wells utilize water jets to create the borehole. The design and construction of these wells make them suitable for accessing shallow groundwater sources, often found in unconsolidated sedimentary deposits.

This well point setup is vital for ensuring the efficient extraction of groundwater without excessive sedimentation. Other options incorrectly attribute methods, depth, or treatment requirements that do not align with the fundamental characteristics of driven and jetted wells.
