SOCIAL ISSUE / ENVIRONMENT: Groundwater That Glows Yellow-Green
UPSC | CSE SYLLABUS
GS-III (Environment/Pollution); GS-II (Governance — implementation gaps between NGT orders and State action); Static GK — industrial pollutants and their health effects.
Why in News
Decades of industrial waste dumping have contaminated groundwater with hexavalent chromium (Chromium VI) across parts of three districts in Uttar Pradesh — Fatehpur, Kanpur Dehat, and Kanpur Nagar — exposing villagers to unsafe water and serious health risks.
Key Facts
|
Aspect |
Detail |
|
Contaminant |
Hexavalent chromium (Chromium VI) — bright yellow-green, highly reactive, a naturally occurring metal compound produced by chemical industries (electroplating, wood preservation) |
|
Source |
Chromium sulphate manufacturing for the Kanpur leather-tanning industry (tanneries operating since the 19th century) |
|
2025 govt. report finding |
73-96% of blood samples from affected residents had above-permissible levels of Chromium (VI) |
|
Largest dump |
~62,225 metric tonnes of chromium waste at Rania, Kanpur Dehat (came up ~1976); removed only in 2025 after NGT-ordered deadlines were missed |
|
Health impacts reported |
Liver infection, chronic gastro-intestinal issues, skin rashes; IARC classifies Chromium (VI) as a carcinogen when inhaled |
|
Regulatory timeline |
2005: U.P. Pollution Control Board identified 6 polluting factories in Kanpur Dehat, shut them down. 2017: NGT ordered removal of chromium dumps in Kanpur Nagar |
Static/Conceptual Linkage
- Hexavalent chromium is used in electroplating, wood preservation, and leather tanning (chromium sulphate).
- International Agency for Research on Cancer (IARC) — under WHO — classifies substances into carcinogen groups; Chromium (VI) compounds fall under Group 1 (carcinogenic to humans) when inhaled.
- National Green Tribunal (NGT) — statutory body under the National Green Tribunal Act, 2010, for expeditious disposal of environmental cases.

GS-I (Geography — interstate rivers); GS-III (Environment — EC process, NBWL role); Inter-state river water disputes (Karnataka-Goa), akin to Cauvery (Karnataka-Tamil Nadu) discussed elsewhere in this edition.
Mahadayi Diversion
Why in News
The Union government told the Lok Sabha that there is no proposal before it from Karnataka seeking Environmental Clearance (EC) for diversion of the Mahadayi river for various projects — a reply given by Minister of State for Environment, Forest and Climate Change Kirti Vardhan Singh to a question by a Goa MP.
Key Facts
|
Aspect |
Detail |
|
River |
Mahadayi (also called Mandovi in Goa) — flows from Karnataka through Goa |
|
Dispute |
Karnataka's plans (Kalasa-Banduri Nala diversion project) vs. Goa's drinking water security concerns |
|
NBWL status |
National Board for Wildlife has NOT approved Karnataka's proposal to use 10.6852 hectares of forest land for the Kalasa Nala Diversion Scheme, which falls in the tiger corridor between Kali and Sahyadri Tiger Reserves |
|
Pending studies |
No Cumulative Impact Assessment (CIA) or Carrying Capacity Study (CCS) of the Mahadayi basin has been submitted by concerned State governments |
|
Goa's concern |
Potential impact on drinking water security, saline ingress, and freshwater aquifers in the river basin |
3. GEOGRAPHY / ENVIRONMENT: MSC Elsa 3 Sinking — No Significant Impact on Lakshadweep, Says Study
Source: The Hindu,
Why in News
A comprehensive assessment by the Chennai-based National Centre for Sustainable Coastal Management (NCSCM) on the potential environmental impact of the MSC Elsa 3 shipwreck (sunk off the Kerala coast on May 25, 2025) on the Lakshadweep islands found no measurable ecological or socio-economic damage to the archipelago.
Key Facts
|
Aspect |
Detail |
|
Vessel |
MSC Elsa 3 — container ship carrying hazardous cargo; sank off the Kerala coast in the Arabian Sea, May 25, 2025 |
|
Study body |
National Centre for Sustainable Coastal Management (NCSCM), Chennai — under directives of the National Green Tribunal |
|
Findings |
Physiochemical parameters of seawater/sediments within natural baseline ranges; no stress in plankton, benthic assemblages, coral reefs, seagrass meadows, or lagoonal habitats |
|
Trigger for study |
NGT took suo motu cognisance of a report titled 'Containers from sunken ship likely to drift towards Alappuzha, Kollam Coasts in 48 hours: INCOIS', published in The Hindu |
|
Broader lesson |
Underscores the vulnerability of remote island ecosystems to maritime accidents; highlights need for early warning systems, island-specific contingency planning, and sustained environmental monitoring |
Exam Relevance
GS-I (Geography — Lakshadweep archipelago, Arabian Sea); GS-III (Disaster Management, Environment); Static — INCOIS (Indian National Centre for Ocean Information Services), NGT suo motu powers.
