The Central Pollution Control Board (CPCB) has stated in its report that the reverse boring technique was allegedly used at the Zira ethanol plant to dispose of harmful chemicals, which led to contamination of underground water, thus making it unfit for drinking.
Ironically, the management had claimed that it was a ‘zero liquid discharge unit’.
Kapil Arora, member, Public Action Committee, said the reverse boring method was used to dispose of toxic chemicals into the ground at the ethanol plant.
The plant management had reportedly drilled 25 borewells to dump toxic waste, which polluted groundwater within a radius of 15 km.
