Aquifer testing is a method used to evaluate the properties of an aquifer, which is a geological formation that can store and transmit water. This testing helps determine how much water can be extracted sustainably, the rate of water flow, and the quality of the water. Common tests include pumping tests and slug tests, which measure changes in water levels over time. During a pumping test, water is pumped from a well, and the response of nearby wells is monitored. This data helps hydrogeologists understand the hydraulic conductivity and storage capacity of the aquifer. The results are essential for managing water resources and ensuring a reliable supply for communities and ecosystems.
