This happened following a thunder burst on April 5.
According to Mahammad Ashlam of KBK Samachar, the local news agency, the downpour lasted 45 minutes and resulted in a huge run-off of the toxic waste into nearby water bodies from a crack in the pond wall of the one-million-tone refinery. Red mud or bauxite residue is a waste product of the alumina manufacturing process.
A video shot by KBK Samachar shows seepage of red mud into some water bodies.
