Scientists from the University of Bath, UK (www.bath.ac.uk) have developed a low cost device that could be used in developing countries to monitor the quality of drinking water in real time without costly lab equipment. Current methods of detecting pollu- tants in water such as mass spectrometry are costly, time consuming and require specialist technical exper- tise. However, researchers from the University in col- laboration with Bristol Robotics Laboratory at the Uni- versity of the West of England, have created a low cost sensor using 3D printing technology that can be used directly in rivers and lakes for continuous water quality monitoring.
