Enewetak

Enewetak Atoll, also spelled Eniwetok Atoll, is a coral atoll in the Marshall Islands in the western Pacific Ocean. It consists of a ring of dozens of small islets surrounding a central lagoon, forming a relatively large atoll geometry. The atoll is administered as part of the Marshall Islands and remains sparsely populated, with a small community on select islets.

Enewetak is notable for its role in the United States’ nuclear testing program during the late 1940s through the 1950s. Beginning in 1948, the atoll hosted a series of nuclear detonations, including atmospheric and other tests conducted as part of the broader Cold War weapons development. The tests resulted in substantial radioactive contamination of land, lagoon waters, and ecosystems, and the resident population was relocated to other islands during the testing period.

In the following decades, cleanup and remediation efforts were undertaken under arrangements between the United States and the Marshall Islands. Contaminated soil and debris were removed, and parts of the atoll were rehabilitated for habitation, though some areas remain restricted due to residual radiation. The environmental and health impacts, along with compensation and long-term monitoring, have continued to be areas of concern and study.

Today, Enewetak stands as a historical site reflecting the nuclear testing era and its legacy. It remains part of ongoing environmental monitoring and research within the Marshall Islands, contributing to broader discussions about nuclear history, remediation, and the rights and well-being of affected communities.
