After completion of construction, a well test is performed to determine the capacity of the well to yield water over time. This can be done with a pump, a bailer bucket, or by blowing compressed air into the well bore. A component of this test is the monitoring of the well's drawdown. Drawdown is the change in water level in the well due to pumping. * A 1-hour test is considered the minimum period necessary to evaluate a well, with 4-hour and 24-hour tests being more reliable. This information is necessary to determine the usefulness of the well for its desired purpose and the size of pump it can support.
