The Bihar Illegal Sand Mining Scam

A Rajasthan-based company allegedly excavated ₹131 crore worth of river sand from Bihar's Banka district over seven years without paying royalties — a network the ED traced from Patna to Delhi and Jaipur using satellite imaging.

The Promise

Riverbed sand mining in Bihar will occur only under valid state mining licences, with royalties paid on all extraction, protecting river ecosystems and state revenue alike.

Bihar mining and geology department regulatory framework, State regulator of riverbed sand mining licences and royalty collection · 1 April 2015

The ED's investigation centres on Mahadev Enclave Private Limited, a company controlled by Ashok Chandak and his son Raghav Chandak of Sriganganagar, Rajasthan, alleged to have illegally mined sand from rivers in Banka district over several financial years.

02

The Standard

Sand mining conducted strictly within licensed limits, with royalties paid to the state exchequer on all extracted volumes, and no unlicensed commercial exploitation of riverbeds.

Bihar Minor Mineral Concession Rules and state mining royalty regulations.

The Reality

The ED alleges that Mahadev Enclave Private Limited illegally extracted sand from rivers in Banka district, Bihar, between financial years 2015-16 and 2022-23, with the value of illegally mined sand estimated at over ₹131 crore, causing losses to the state exchequer through unpaid royalties. The agency's case draws on a geospatial analysis commissioned from IIT Patna in October 2024, which found evidence of large-scale illegal excavation. On 17 July 2026, the ED conducted searches at eight locations across Banka and Patna in Bihar, Delhi-NCR, and Jaipur and Sri Ganganagar in Rajasthan under the Prevention of Money Laundering Act, seizing ₹1.53 crore in cash. The ED has also formally flagged the ₹131 crore scam to the Bihar government and sought a fresh FIR.

Verdict

Under TrialLow confidence

Preliminary verdict, pending fuller research: the ED's use of satellite/geospatial analysis to quantify illegal riverbed mining is a notable investigative approach, but the case remains at the raid-and-referral stage, with no criminal case yet formally registered by Bihar authorities as of the most recent reporting reviewed.

This entry is based on a handful of independent reports of the July 2026 ED raids and referral; it has not been possible to confirm whether Bihar authorities have since registered the fresh FIR the ED sought.

09

What remains incomplete

  • This is a stub entry; whether the Bihar government has registered the fresh FIR the ED requested has not been confirmed.
  • Whether any arrests have followed the July 2026 raids has not been tracked.
  • A separate, larger reported figure of a ₹2,407 crore illegal sand mining network across Hyderabad, Jaipur, and Coimbatore may or may not be linked to this same company; this has not been reconciled here.

The Green Revolution Made India Food Self-Sufficient. Six Decades On, Punjab's Water Table Is Paying the Bill

India's Green Revolution of the 1960s and 70s was framed as the answer to famine and food-grain dependence -- high-yield seeds, irrigation and fertiliser to make the country self-sufficient. It largely delivered that goal, transforming India into a major food producer and exporter. But the same package of practices, concentrated heavily in Punjab, Haryana and western Uttar Pradesh, has been linked by decades of subsequent research to severe groundwater depletion, soil degradation and regional inequality that policymakers are still grappling with.
