What is a test well primarily used for?

A test well is primarily used for exploring for groundwater. This involves drilling a well to assess the quantity and quality of groundwater in a specific area. By testing the well, drillers can gather vital information about water levels, flow rates, and the geological characteristics of the aquifer being investigated. This data is fundamental in determining the viability of groundwater extraction for various uses such as agricultural, industrial, or municipal. Additionally, test wells can be instrumental in understanding how groundwater interacts with surface water and surrounding ecosystems.

Monitoring water quality, although important, is typically a subsequent step that may follow the exploratory phase. Removing surface water and discharging aquifer water are not primary functions of a test well; these processes generally involve other types of systems designed for managing water resources rather than assessing or investigating groundwater potential.
