Living in poverty often means consuming contaminated drinking water. Assembled by the Blum Center for Global Engagement, Katya Cherukumilli earned recognition in June 2015 at the University of California Irvine’s Designing Solutions for Poverty challenge. She has been addressing and innovating ways to cheaply eradicate fluoride from drinking water by using a remediation solution in groundwater. In doing so, she is helping to protect those without any other source for cleaner water.

Katya Cherukumilli developed a cheap way to use bauxite, a material that produces alumina and aluminum, in order to filter out fluoride in drinking water. She is a PhD student at the University of California, Berkley, set to complete an Environmental Engineering Degree in 2017. Her work with the Gadgil Lab for Energy and Water Research found a cheap solution to the problem concerning fluorosis.

The Gadgil Lab is located at the University of California, Berkley. Its mission is to alleviate poverty using research and engineering studies. Katya Cherukumilli is working specifically with fluoride removal. Having been born near the district of interest, Nalgonda, she feels, according to Alex Chan with Daily Pilot, “This is something that is very close to my heart. Access to clean water does not seem like something people should die for.”

According to Gadgil Lab, drinking excessive levels of fluoride, above 1.5 mg/L, can cause anemia, discolored enamel and bone deformities, also known as skeletal fluorosis. Affected groundwater exists on a global scale in places like Sri Lanka, China, Est African Rift Valley, northern Mexico and Argentina.

With 200 million people drinking toxic water, 66 million in India are at risk. A site is open for examining the water in Telegana, where contamination is the most acute and fixated. Ten percent of this district has been affected and 10,000 are permanently deformed.

Groundwater in the Nalgonda District in India has a toxic amount of fluoride that causes deformities with excess intake. Skeletal fluorosis patients reside here. Granite rocks underground are breaking apart and contaminating drinking water with fluoride.

A toxic level of fluoride in drinking water is a problem that has been known for six decades. When rural areas cannot reach safer alternatives, the problem continues. Responding to this issue takes time and manpower. Areas where innovations are costly, difficult to set up or culturally ineffective make it difficult to introduce defluoridation. Gadgil Lab lists a few requirement guidelines addressing the issues.

Any technology useful to the cause must be local, affordable, and appropriate for the culture. It should require minimal maintenance and must function very successfully in the rural area.

To satisfy these requirements, Cherukumilli has been researching bauxite ore. She found that remediating groundwater fluoride needs to be more cost-effective. Cherukumilli is refining bauxite in order to minimize expenditure per person per year from $50 to $1.

Her method to reduce cost includes improving sustainability, so less material is required. Also less energy and carbon costs are needed to solve the issue.

Forty community leaders, scientists, business partners and investors at the competition agreed her progress in this field of study has absolute potential. It will protect the less fortunate from further disfigurement that affects them socially, economically and medically. Her presentation at the Irvine’s Designing Solutions for Poverty challenge received the popular vote among three others.
