Description
This photograph shows a scientist taking a depth to watertable measurement using a piezometer (the PVC tube in the ground with openings into the groundwater near its bottom) and an electric sensor. The sensor has positive and negative electrodes that are insulated from one another. When the contact the groundwater the electrical circuit is completed and a buzzer sounds on the sensor. A tape measure on the role of wire that feeds the sensor down the piezometer allows the user to measure the depth to the watertable.
