Low-Cost Water Pollution Spectrometer for Monitoring Map
Doyeon Pi of PiQuant and Ki-Hun Jeong of the Korea Advanced Institute of Science and Technology both in the Republic of Korea will develop their small, low-cost, water quality test equipment and a GIS-based monitoring system to continuously map water quality in real time across Vietnam. Despite the extensive river network running though the country, many Vietnamese remain short of clean water. Drinking water can be polluted by many different pathogenic microorganisms such as Salmonella that cause disease. Spectroscopic devices are used to monitor water quality, but they require expensive time-consuming procedures to remove background noise and improve accuracy. They have built a small spectroscopic device incorporating a noise-cancelling algorithm that can quickly and accurately measure water quality at a much lower cost than traditional devices. They will collaborate with universities and research institutes in Vietnam to identify the major water pollutants in each region and develop a prototype water scanner. This will be distributed in a pilot area to demonstrate preliminary proof of performance for measuring water quality. They will also set up a GIS-based monitoring system that maps the water quality data and provides users with easy access.
