Chupadera Mesa

Approximately 28 miles northeast of the Trinity atomic bomb test site on the White Sands Missile Range , Northeast of Bingham , New Mexico

The Chupadera Mesa Site is privately owned land northeast of the White Sands Missile Range and the city of Bingham in New Mexico. The site was in the fallout zone of the first nuclear weapons test, the Trinity test, conducted on July 16, 1945. The test was part of the Manhattan Project that was established during World War II to conduct research for the development and production of nuclear weapons.

The U.S. Atomic Energy Commission and successor organizations monitored the site between 1945 and 1985. In 1986, DOE determined that residual radioactive materials met applicable standards, did not require remediation under FUSRAP, and released the site for unconditional use.

No supplemental limits or institutional controls are in effect at the site, and DOE does not require on-site monitoring or surveillance. Legacy management activities consist of managing site records and responding to stakeholder inquiries.
