Ludhiana, Sept. 22 -- After residents of Guru Nanak Nagar, near Noorwala Road, complained about hot and discoloured water coming from their submersible pumps, the Punjab Pollution Control Board (PPCB) has taken cognisance of the issue and initiated action.

Residents had been alarmed after noticing unusual coloured and warm water coming out of their underground water supplies. They suspected illegal discharge from nearby dyeing units into the sewerage system, which could be polluting the groundwater.

Following the complaint, PPCB officials visited the area and collected water samples from the sewerage lines and a nearby dyeing unit, which is allegedly involved in releasing untreated waste.
