The Problem:

About 60 million individuals in West Bengal and Bangladesh, along with millions more in China, Nepal, and Cambodia, are exposed to high levels of naturally occurring arsenic every time they drink from their local well.

The Solution:

The team have developed and patented Electro Chemical Arsenic Remediation (ECAR) which enables low cost affordable arsenic-remediation of water, within a sustainable service delivery model. Under this model, safe water would be provided to school children while excess may be sold at a low cost affordable price. This public-private partnership would ensure that the plant is not abandoned due to failed maintenance that has plagued other implementations.
