Water is essential for human life but millions in India do not have access to safe drinking water. One of the contaminants of groundwater is Arsenic, a metalloid naturally present in Earth’s crust. Some regions have much higher arsenic concentrations than others due to geological and anthropogenic activities, and this can be problematic. A 2011 survey found 17 districts in Assam with arsenic contamination. Titabor subdivision, comprising 20 gaon panchayats, was the most affected. In this episode we speak to Prithvi Ram, a researcher working on critical issues related to water resources management in south Asia in general and arsenic contamination in Titabor in particular.
