The Centre for Water Resources Development and Management (CWRDM) informed the SPCB that to identify the source of contamination of well water, the tracer study would be most effective if conducted during summer season. "This is because there will be more draft of water which leads to faster movement of groundwater during summer", CWRDM said.

The electroplating units were inspected by SPCB, November 19, 2021. Two of the units were not working during the time of inspection. The effluent treatment plant of the electroplating units were found functional and the treated water was found being reused in the process.

It is submitted that even though these units have zero discharge, standards have been specified for the quality of treated effluent in the consent to operate, as a matter of abundant caution. Treated water samples were collected and forwarded to lab for analysis and the results are awaited, the report dated December 24, 2021 said.
