The indiscriminate act of dumping hazardous solid waste on the roadsides has commenced once again in Erode town and its suburbs. More than 50 bags of sludge from the textile processing and tannery units have been dumped in Choolai, a thickly populated residential colony in Erode town on Wednesday.

Though the activity had been going on, on the sly, for years in different parts of the district, the units had stopped the dumping for a brief period as the officials in the revenue department and Tamil Nadu Pollution Control Board (TNPCB) stepped up the vigilance.
