Ezeiza Atomic Centre in Buenos Aires, Argentina

The Ezeiza Atomic Centre is a nuclear waste facility and research centre. Surrounding communities are concerned about the nuclear waste being stored on site and lack of transparency from the government about uranium contamination levels.


The Ezeiza Atomic Centre, located in a suburb of Buenos Aires, Argentina, is a nuclear research facility which specialises in radioisotope and nuclear fuel production and nuclear radioactive waste storage. It is operated by the National Atomic Energy Commission (CNEA) [1].

Court decision (undecided)
Development of alternatives:A study was produced by a geologist from the University of Buenos Aires who was contracted by a judge after lack of funding to have water quality tested abroad. In 2004, he produced a report over 600 pages long which became anonymously public and caught the attention of locals, but also the Argentine Nuclear Regulatory Authority (ARN). The report shows significant uranium contamination of drinking water, and other radioactive agents. In response to this, the ARN stated that they carry out regular testing and results always comply with government standards [3].
Do you consider this an environmental justice success? Was environmental justice served?:No
Briefly explain:The Ezeiza Atomic Centre is not disclosing most of its reports and other information regarding contamination levels, radiation levels etc, and therefore environmental justice is not currently served unless independent studies are conducted, transparency is enabled and the issues are resolved.

Moreover, residents felt angered by the lack of action once the report from University of Buenos Aires was released, as they criticised the judge who ordered the report to be conducted for not taking precautionary measures, and many say that the report was never supposed to be seen by the public [3]. The lack of concern from the ARN regarding the report findings and their arguments against the contamination levels leaves the public feeling as if no one is protecting them from the dangers.
