Making the paper: Scott Fendorf.

The article reports on the work of Scott Fendorf to prevent health crisis in south and south east Asia regions due to arsenic contamination. It notes that Fendorf began collaborating with a colleague who had hydrological and geochemical data from the Ganges-Brahmaputra delta in Bangladesh and the Mekong Delta in nearby Cambodia. A physician working for the Cambodia-based nonprofit organization and Cambodian government also collaborated with Fendorf's group work. His group came up with a well array that would first determine water flows, and later allows water and soil monitoring. Fendorf added that it would take more than 100 years for arsenic to travel naturally through river-based sediments to reach the underlying aquifer.
