Achievements: 
Ashok Gadgil received an award from San Jose’s (CA) Tech Museum of Innovation, which honors people who use technology to help humanity, for developing a water purification system that kills bacteria with ultraviolet light. The system, called UV Waterworks and marketed by WaterHealth International, Inc., is used daily by about 300,000 people in Mexico, the Philippines, and several other countries. Several systems will soon be installed in his native India. Money is currently being raised to install the system in tsunami-stricken regions of Sri Lanka and India. His invention appeared in Forbes Magazine in 2003. Ashok Gadgil is also developing a cheap and effective way to provide safe drinking water to 60 million Bangladeshis who live under the specter of arsenic poisoning. His idea is to create arsenic filters from coal ash, the fine gray powder that piles up at the bottom of furnaces at all coal-fired power stations, waiting to be discarded. Although still in the investigational stage, Gadgil’s technique would involve coating the ash with a compound that attracts arsenic, filling teabag-sized pouches with the powder, and distributing the filters throughout the countryside, one per family per day. Water drawn from any one of the millions of contaminated wells that dot Bangladesh could then be poured through the filter and safely consumed. Gadgil has numerous publications spanning the areas of drinking water efficiency and indoor air quality.
