According to the World Health Organization (2012), about 780 million – about 1 in 9 – people lack access to clean water and 3.4 million peopled died as a result of contaminated water, with 99% of those deaths occurring in the developing world (2008). And, while communities and organizations struggle to improve the quality of drinking water in these areas, methods for detecting water contaminants may be necessary to determine whether or not a water supply is safe. Relying on a sample of electricity producing bacteria and 3D printing technology, researchers at the University of Bath’s Department of Chemical Engineering have developed a low-cost solution to this problem, that doesn’t require expensive lab equipment.…
