Untreated sewage, industrial effluents, agricultural runoff and weak enforcement of environmental regulations have degraded several river systems. According to the Central Pollution Control Board\u2019s (CPCB) 2025 assessment, based on water-quality data from 2022 and 2023, India had <\/span><b>296 polluted river stretches across 271 rivers in 32 States and Union Territories<\/b><span style=\"font-weight: 400;\">, down from 351 stretches identified in 2018.<\/span><\/p>\n<p><b>Why in the news?<\/b><span style=\"font-weight: 400;\"> In October 2026, during ongoing suo motu proceedings concerning pollution in Rajasthan\u2019s Jojari-Luni-Bandi river system, the Supreme Court warned that it could order a Central Bureau of Investigation (CBI) probe into alleged illegal mining and the regularisation of mining leases. The case highlights the need for stronger pollution control, regulatory accountability and river restoration.<\/span><\/p>\n<h2><b>What is River Pollution?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">River pollution refers to the contamination of river water by harmful substances, including untreated sewage, industrial waste, agricultural chemicals and solid waste. It degrades water quality and affects aquatic ecosystems, human health and livelihoods that depend on rivers.<\/span><\/p>\n<h3><b>Key Water-Quality Indicators<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Water quality is assessed through physical, chemical and biological parameters. Three important indicators for understanding river pollution are:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b><a href=\"https:\/\/vajiramandravi.com\/upsc-exam\/biological-oxygen-demand-bod-is-a-standard-criterion-for\/\" target=\"_blank\">Biochemical Oxygen Demand<\/a> (BOD):<\/b><span style=\"font-weight: 400;\"> Measures the oxygen required by microorganisms to decompose organic matter in water. Higher BOD generally indicates greater organic pollution.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Dissolved Oxygen (DO):<\/b><span style=\"font-weight: 400;\"> Refers to the oxygen available in water for aquatic organisms. Low DO can stress or kill fish and other aquatic life.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Faecal coliform:<\/b><span style=\"font-weight: 400;\"> Bacteria used as an indicator of faecal contamination and possible microbial health risks. Their presence can signal contamination from sewage or animal waste.<\/span><\/li>\n<\/ul>\n<h2><b>Major Causes of River Pollution<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">River pollution results from the discharge of untreated waste, unsustainable land use and inadequate enforcement of environmental regulations.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Untreated sewage:<\/b><span style=\"font-weight: 400;\"> Domestic wastewater released without adequate treatment introduces organic matter, pathogens and nutrients into rivers.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Industrial effluents:<\/b><span style=\"font-weight: 400;\"> Industries such as textiles, tanneries, chemical manufacturing and paper production may release toxic substances and heavy metals into water bodies.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Agricultural runoff:<\/b><span style=\"font-weight: 400;\"> Fertilisers and pesticides enter rivers through surface runoff, contributing to nutrient pollution and harming aquatic life.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Solid waste and plastics:<\/b><span style=\"font-weight: 400;\"> Dumping plastic, household waste and other refuse degrades water quality and can harm aquatic organisms.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Religious and cultural activities:<\/b><span style=\"font-weight: 400;\"> Poorly managed disposal of offerings and non-biodegradable materials can add to river pollution.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Urbanisation and encroachment:<\/b><span style=\"font-weight: 400;\"> Construction, stormwater runoff and encroachment on riverbanks increase pressure on river ecosystems.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Mining and sand extraction:<\/b><span style=\"font-weight: 400;\"> Unregulated mining and sand extraction can disturb riverbeds, increase sedimentation and damage aquatic habitats.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Weak enforcement:<\/b><span style=\"font-weight: 400;\"> Inadequate monitoring, insufficient sewage-treatment capacity and non-compliance with environmental standards allow pollution to continue.<\/span><\/li>\n<\/ul>\n<h2><b>Effects of River Pollution<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">River pollution affects human health, ecological balance, economic activities and the availability of safe water.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Human health:<\/b><span style=\"font-weight: 400;\"> Contaminated water can spread waterborne diseases and expose people to toxic substances.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Aquatic biodiversity:<\/b><span style=\"font-weight: 400;\"> Low dissolved oxygen, toxic chemicals and altered habitats threaten fish and other aquatic organisms.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Agriculture:<\/b><span style=\"font-weight: 400;\"> Polluted water used for irrigation can affect soil quality and introduce harmful contaminants into the food chain.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Drinking water:<\/b><span style=\"font-weight: 400;\"> Pollution increases the cost and complexity of treating water for domestic use.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Economic losses:<\/b><span style=\"font-weight: 400;\"> Fishing, tourism and other river-dependent livelihoods can suffer due to declining water quality.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Eutrophication:<\/b><span style=\"font-weight: 400;\"> Excess nutrients from sewage and fertilisers can cause algal blooms, reduce oxygen levels and harm aquatic life.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Ecosystem degradation:<\/b><span style=\"font-weight: 400;\"> Pollution damages river habitats and disrupts ecological processes.<\/span><\/li>\n<\/ul>\n<h2><b>Measures to Control River Pollution\u00a0<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Immediate pollution-control measures must focus on preventing untreated waste from entering rivers and ensuring compliance with environmental standards.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Sewage treatment:<\/b><span style=\"font-weight: 400;\"> Expand sewage-treatment capacity and ensure wastewater is treated before discharge into rivers.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Industrial compliance:<\/b><span style=\"font-weight: 400;\"> Enforce effluent standards and require industries to operate and maintain appropriate treatment systems.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Solid waste management:<\/b><span style=\"font-weight: 400;\"> Improve waste collection, segregation and disposal to prevent plastics and household refuse from entering waterways.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Agricultural practices:<\/b><span style=\"font-weight: 400;\"> Promote balanced fertiliser use, responsible pesticide application and vegetative buffer zones along riverbanks.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Regular monitoring:<\/b><span style=\"font-weight: 400;\"> Strengthen water-quality testing and use monitoring data to identify pollution sources and track compliance.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Environmental compensation:<\/b><span style=\"font-weight: 400;\"> Impose penalties and recover environmental compensation from polluters in accordance with applicable law and judicial directions.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Community participation:<\/b><span style=\"font-weight: 400;\"> Involve local bodies, civil society organisations and residents in river-cleaning and pollution-prevention activities.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Riverbank protection:<\/b><span style=\"font-weight: 400;\"> Control encroachment and regulate activities that damage river channels and riparian
