Ltd., a company that is tackling the widespread problem of arsenic contamination using a technology developed through years of research. Arsenic contamination is a serious health concern in India, with the potential to cause cancers, neurological and cardiovascular diseases, and impaired cognitive function, especially in children. The toxic chemical is mostly found in groundwater, the source of drinking water for many rural communities in the country. This led to a research-backed, field-tested technology to purify arsenic-tainted water, which garnered support from government and national institutions. The Bengal basin has the highest incidence of arsenic contamination, with areas such as Patna, Vaishali, Bhagalpur, Munger, and Buxar affected.
