Q. Industrial pollution of river water is a significant environmental issue in India. Discuss the various mitigation measures to deal with this problem and also the government’s initiatives in this regard.

Model Answer:

Industrial effluents containing heavy metals and toxic chemicals severely degrade India’s riverine ecosystems, threatening both water security and public health.

Mitigation Measures for Industrial River Pollution

• Zero Liquid Discharge (ZLD): Mandating complete wastewater recycling in highly polluting industries to entirely eliminate toxic liquid discharge.
• Common Effluent Treatment Plants (CETPs): Building pooled treatment infrastructure for MSME clusters to ensure economic viability (e.g., Tiruppur textile cluster).
• Stringent Enforcement: Deploying real-time monitoring with heavy penalties and closure notices for non-compliant Grossly Polluting Industries (GPIs).
• In-situ Treatment: Employing bioremediation, phytoremediation, and constructed wetlands to naturally degrade pollutants before reaching main river streams.

Key Government Initiatives

• Statutory Framework: Strict regulation and penalization of unauthorized industrial discharge (Water (Prevention and Control of Pollution) Act, 1974).
• Namami Gange Programme: Continuous monitoring, upgrading CETPs, and sealing non-compliant GPIs specifically across the Ganga river basin.
• OCEMS Portal: The Central Pollution Control Board’s (CPCB) Online Continuous Effluent Monitoring System for 24×7 tracking of industrial discharge.
• National River Conservation Plan (NRCP): Providing federal financial and technical assistance to states for upgrading effluent treatment infrastructure.

Shifting towards a circular water economy by strictly enforcing the “Polluter Pays Principle” and incentivizing green technologies is crucial for revitalizing India’s rivers.
