CANACONA: River Rejuvenation Committee constituted by the order of the National Green Tribunal has proposed the implementation and execution of the action plan to rejuvenate the polluted stretches of Talpona river.
Talpona River which originates in the dense, mixed pristine jungles of Ravan Dongar in between Nane and Kuske on the Sahyadri Mountains is one of the important rivers of Goa.
While meandering through the jungles it traverses about 40 kms sustaining vast species of flora and fauna since millions of years ago.
The river which was unpolluted till now has a total basin area of 233 sq km which is 6.30% of Goa’s geographical area and has a runoff of 515.6 Million Cubic Metres (MCM) and is important in all aspects to the people of Canacona and more for the drinking water needs of the taluka.
On the basis of the study conducted by Goa State Pollution Control Board (GSPCB) between January 2015 and December 2018, the Central Pollution Control Board has classified this stretch within Talpona River as polluted and has placed it under Priority IV for having Biological Oxygen Demand (BOD) level of 6.8 mg/lit.
The action plan published by the River Rejuvenation Committee says that the report of monitoring for the period April 2015 to December, 2018 at one location for the parameters of Dissolved Oxygen (DO), Biological Oxygen Demand (BOD) and Total Coliform (TC) have been taken into consideration for the preparation of the Action Plan to rejuvenate the Talpona River.
It is also stated that the action plan strategies will be implemented by stakeholder departments concerned by taking necessary action for disconnection of direct discharges of domestic sewage and improvement in the collection and storage of the solid waste in the panchayat concerned.
The NGT / CPCB on the basis of the results compiled by GSPCB has also declared 5 km upstream of Talpona river from where it meets the Arabian sea as polluted stretch and has categorised it under Class-C (drinking water source).
The proposed action plan for Talpona River rejuvenation includes total disconnection of the direct discharge into the river/storm water drain/nallahs; installation of bio-toilets construction of septic tanks and soak pits by residential houses; toilet facility at the fishing jetty at Talpona; controlled ground water extraction and periodic quality assessment; periodic monitoring of ground water resources and regulation of ground water extraction by industries particularly over exploited and critical zones.
