Hudson River: 60 Years of Radioactive Water Discharge
10 Apr
Summary
- Millions of gallons of radioactive water discharged annually for over 60 years.
- A 1970 federal investigation documented massive fish kills and chemical concerns.
- New plan approves annual release of 45,000 gallons from the defunct plant.

Radioactive water was discharged into New York's Hudson River for over 60 years, with millions of gallons released annually during the operation of the Indian Point nuclear plant. This practice is facing renewed scrutiny following a recent court approval for a plan to release an additional 45,000 gallons of treated radioactive water per year from the now-shuttered facility.
Records indicate the plant discharged an average of two to three million gallons of processed wastewater yearly between 1962 and 2021. A federal investigation in 1970 found that millions of fish died due to the plant's cooling system and documented chemical discharges that exceeded state safety limits. Testing near the plant also detected increased radioactivity in nearby water, sediment, vegetation, and fish.
Holtec International, the plant's current owner since 2021, states that no releases under its ownership have exceeded federal limits and that all discharged batches are tested. The company is responsible for the plant's decommissioning, including managing stored wastewater. Despite past investigations finding no definitive proof of widespread ecosystem collapse, significant harm was documented.
Environmental advocates remain concerned about the cumulative impact of decades of releases. With ongoing restoration efforts for the Hudson River, future discharges will be closely monitored for their potential effects on the waterway's recovery.
