PANJIM: The state government has decided to ask the Central Pollution Control Board (CPCB) to remove from the list of polluted rivers five river sections — Chapora, Assonora, Valvonti, Khandepar and Talpona, because the quality of the water meets standards.

In 2018, the CPCB, in a list submitted to the National Green Tribunal (NGT), had designated the Mandovi, Zuari, Sal, Talpona, Assonora, Bicholim, Chapora, Khandepar, Sinquerim, Tiracol and Valvanti rivers as polluted rivers according to criteria III , IV and V, i.e. have a biochemical oxygen demand (BOD) between 10 and 20 mg/l, between 6 and 10 mg/l and between 3 mg/l. A total of 11 rivers have been identified in the polluted list.

During the State River Rejuvenation Committee (RRC-Goa) meeting held on Wednesday, Environment Secretary Arun Kumar Mishra reviewed the follow-up action and requested an update on the status of all relevant departments with regard to the on-site implementation of the various action plan strategies listed. in the action plan prepared for the regeneration of 11 polluted river sections.

The meeting reviewed the assessment of water quality parameters – PH, Dissolve-Oxygen (DO) and BOD), total/fecal-colliform according to the CPCB classification with respect to the trend for a period from May 2019 to April 2021.

During the review, it was noted that out of 11 river sections, five river sections namely Chapora, Assonora, Valvonti, Khandepar and Talpona are in compliance with the standards prescribed by the CPCB.
