(15 marks)

Model Answer

Introduction

As highlighted in The Assam Tribune (06 February 2026), arsenic contamination in groundwater continues to affect several districts of Assam, particularly in the Brahmaputra floodplain. Often termed a “silent killer”, arsenic contamination poses long-term health risks while remaining largely invisible in its early stages. The issue reflects the complex linkage between geology, water governance, public health, and social equity.

Body

A. Causes of Arsenic Contamination in Assam

Geogenic Factors

Naturally occurring arsenic is released from alluvial sediments into groundwater under specific hydro-geological conditions.

Overdependence on Groundwater

Excessive use of shallow tube wells for drinking water increases exposure.

Hydrological Dynamics

Seasonal flooding and changing redox conditions in the Brahmaputra basin mobilise arsenic.

Inadequate Water Quality Monitoring

Limited testing and delayed identification of contaminated sources.

B. Impacts

Public Health Consequences

Long-term exposure leads to arsenicosis, skin lesions, cancers, and organ damage.

Social and Economic Costs

Affects productivity, increases healthcare expenditure, and deepens rural poverty.

Water Security Challenge

Undermines access to safe drinking water, especially for marginalised communities.

Intergenerational Risk

Chronic exposure impacts children’s physical and cognitive development.

C. Challenges in Mitigation

Detection Gaps due to inadequate testing infrastructure.
Infrastructure Deficit, particularly limited piped water supply in rural areas.
Low Public Awareness about arsenic risks and symptoms.
Health System Constraints in diagnosis and long-term care.
Fragmented Governance across water, health, and rural development departments.

D. Way Forward

Safe Water Supply Expansion

Accelerate Jal Jeevan Mission coverage with surface-water-based piped supply.

Regular Testing and Mapping

Community-level water testing and public disclosure of results.

Alternative Water Sources

Promote rainwater harvesting and treated surface water.

Health Surveillance

Early diagnosis, medical support, and nutrition-based interventions.

Integrated Governance Approach

Coordination between water resources, health, and local governance institutions.

Conclusion

Arsenic contamination in Assam is not merely an environmental issue but a human development and governance challenge. Addressing it requires a shift from reactive responses to preventive, science-based, and people-centric solutions. Ensuring safe drinking water is fundamental to public health, social justice, and sustainable development, making arsenic mitigation a critical priority for Assam’s governance agenda.
