Executive Summary:

200 million historically marginalized people worldwide have no choice but to drink water containing toxic levels of arsenic. Chronic arsenic poisoning has no cure. Consequences include painful disabilities, internal cancers, and death. We invented and have successfully deployed a robust arsenic-removal technology (ElectroChemical Arsenic Remediation, “ECAR”) to provide poor rural communities with safe, affordable drinking water. ECAR is inexpensive and designed to work even under harsh conditions. It allows water to be purified locally in marginalized communities and sold at affordable prices while creating local employment and generating sufficient revenue for sustainable operation and further expansion. With additional funding, we will build 1,004 plants in India, USA, and Nigeria to provide safe drinking water to 4-5 million people. Our scale-up will demonstrate the financial viability and community engagement needed to cross the adoption tipping point, ending what the World Health Organization has called “the largest mass poisoning in recorded history.”
