Currently, there is a search designated to looking for water in New South Wales central west, using aerial electromagnetic technology.
The search conducted has been primarily funded by the New South Wales Government, in search of groundwater, with the purpose to secure drinking water in the regional communities, which are set to run dry soon.
Given that the government have taken extensive measures to find groundwater, it just goes to show how serious the problem in New South Whales have become. Water is becoming scarcer, hence why the aerial electromagnetic searches have been conducted.
It works by detecting groundwater and minerals, approximately 500 meters below the earth’s surface. The research survey will cover over 19,000 square kilometers, which is roughly 1 ½ times than the Greater Metropolitan in Sydney’s size.
How it Works
According to John Greenfield, the Director of Geoscience Information at Geological Survey explained that the sensor is towed by a high-performance helicopter, which flies at a 60-meter height. It works just like metal detectors and is designed with a transmitter inside of the sensor, which sends out electromagnetic signals, that interact with soil, rocks, as well as the water below the ground. The sensor is then returned and then measured using its return signal and providing an indication of precisely what may be located below the ground and at its exact location.
This aerial electromagnetic technology is referred to as the metal detector of the sky and is an invention hoped to deliver successful results, which will offer many benefits to countries that are experiencing less rainfall or severe water scarcity. Thus far, the technique has been successful, being successfully used in both the U.S. and in South Africa. This new technology could also possibly serve countries by gathering information to prevent future water shortages.
