Well tests are done in completed wells to gather information about the water flow in the well and surrounding areas. Different tests are conducted, like step‐drawdown tests and constant rate pumping tests, to measure water level changes and estimate how water moves in the aquifer. Recovery tests are also done to see how quickly the water level goes back to normal after pumping stops. A slug test is used in small wells to estimate how water flows in the ground. Overall, these tests help scientists understand how water moves in the ground and how to manage it effectively.
