In a major crackdown, the vigilance team of Gujarat Pollution Control Board (GPCB) unearthed illegal discharge of hazardous effluents into Sabarmati and a nearby lake by certain textile processing firms in Narol-Piplaj industrial area.

Six units - Shraddha Processors, Geeta Processors, Vinod Denims, Harekrushna Fabrics, Blue Blend Denims and Mahak Processors - are facing a closure for this unscrupulous discharge. "These units will be closed for at least 15 days," GPCB member-secretary Hardik Shah told TOI.
