'Chemplast claims about zero liquid discharge false'

Twice in the past five months, residents near Mettur in Tamil Nadu have noticed liquid seeping from under the compound wall of Chemplast Sanmar’s PVC plant into the drain running alongside the wall. There was a terrible smell coming from the drain. The recent rains had flushed out the effluent and due to the gradient, the effluent flooded some fields that had been freshly planted with millets. Residents took water samples both times from the drain. The results from the samples taken in May show high levels of chemicals including carcinogens in the water.
