Human-Made Dams Are Shifting Earth’s Poles & New Rules for Contaminated Site Management in India
Introduction
In a world where human interventions are increasingly impacting the environment, two crucial developments have recently drawn attention — the discovery that human-made dams have shifted Earth's poles and the notification of new rules for contaminated site management in India. Both are highly relevant for UPSC aspirants and environmental policy enthusiasts. Here's a comprehensive breakdown by BrainFRA IAS, your trusted platform for UPSC preparation.
Part I: Human-Made Dams Have Shifted Earth’s Poles
What Is True Polar Wander (TPW)?
True Polar Wander (TPW) refers to the rotation of Earth’s crust and mantle about the liquid outer core. It helps Earth maintain rotational balance due to mass redistribution.
Traditionally, What Caused TPW?
Glacial melting
Ice sheet melt
Tectonic plate shifts
Ocean swell
How Are Dams Responsible?
Reservoirs trap large volumes of water that would naturally stay in oceans.
This shifts Earth’s mass inland, disturbing the planet's rotation.
The shift is not uniform — it varies depending on the size and location of the dams.
Effects of This Shift:
Navigation Problems: Affects satellites and space telescopes relying on Earth's rotation.
Longer Days: Days on Earth are getting longer gradually — and this trend is accelerating.
Part II: New Rules for Contaminated Site Management in India – 2025
The Ministry of Environment, Forest and Climate Change (MoEFCC) has released updated rules under the Environment Protection Act, 1986, titled:
Environment Protection (Management of Contaminated Sites), 2025
Key Features of the Rules:
✅ Contaminants Covered:
189 hazardous substances under Hazardous and Other Wastes Rules, 2016.
❌ Exclusions:
Radioactive waste
Mining waste
Oil spills at sea
Solid waste dumps (governed separately)
🔄 Response Levels:
Set differently for agricultural, residential, commercial, and industrial zones.
Framework for Contaminated Site Management:
🔍 Site Identification:
Local bodies must report suspected sites twice a year to State Pollution Control Boards (SPCBs).
🧪 Site Assessment:
SPCBs inspect sites and report findings to CPCB through a central portal.
👥 Polluter Identification:
If the land has a new owner, they may be liable.
🛠 Clean-Up Plan:
Polluter must:
Use an approved clean-up agency.
Pay for the clean-up.
If polluter is unknown ➝ SPCB undertakes clean-up.
💰 Funding:
Initial costs may be covered by:
Central Government via Environmental Relief Fund under Public Liability Insurance Act, 1991
State Governments
If polluter is later identified ➝ they must repay the cleanup cost in 3 months.
⚖️ Penalties:
State Boards may fine owners for failure to clean up.
Especially strict if the site is a health hazard.
