The new method uses water hyacinth, a weed known for its ability to spread rapidly over water bodies. It is used for cleansing polluted water bodies owing to its remarkable capacity of absorbing pollutants.

How Balasore became recognised as a fluorosis-affected district in Odisha

Back in 2015, the Member of Parliament (MP) from Balasore, Odisha got to know about a strange problem in his constituency. There were reports of a number of bone deformities and crippled people in areas surrounding Patripal village of Remuna block. They seemed to be related to fluoride in water, causing a disease called Skeletal Fluorosis.
